Precautions While Using Viagra

Sildenafil has not been studied with other medicines used for treatment of erectile dysfunction. Presently, using them together is not recommended .

It is important that you tell all of your healthcare providers that you take sildenafil . If you need emergency medical care for a heart problem, it is important that your healthcare provider knows when you last took sildenafil.

Use sildenafil exactly as directed by your doctor . Do not use more of it and do not use it more often than your doctor ordered. If too much is used, the chance of side effects is increased.

If you experience a prolonged or painful erection for 4 hours or more, contact your doctor immediately. This condition may require prompt medical treatment to prevent tissue damage of the penis and possible permanent impotence.

This medicine does not protect you against sexually transmitted diseases. Use protective measures and ask your doctor if you have any questions about this.

It is important to tell your doctor about any heart problems you may have now or may have had in the past. This medicine can cause serious side effects in patients with heart problems.

If you experience sudden loss of vision in one or both eyes, stop using sildenafil and contact your doctor immediately.

Before Using viagra

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For sildenafil, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to sildenafil. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy—Sildenafil is not indicated for use in women. Sildenafil has not been studied in pregnant women. However, sildenafil has not been shown to cause birth defects or other problems in animal studies.

Breast-feeding—It is not known whether sildenafil passes into breast milk. Sildenafil is not indicated for use in women for erectile dysfunction. Mothers who are taking this medicine for pulmonary arterial hypertension and who wish to breast-feed should discuss this with their doctor.

Older adults—Elderly people are especially sensitive to the effects of sildenafil, which may increase their chance of having side effects. Patients 65 years of age and older who are taking this medicine for erectile dysfunction are started on a low dose, 25 mg, of sildenafil. Patients who are taking this medicine for pulmonary arterial hypertension may also need to be started at a lower dose. The dose may be increased by a doctor as needed and tolerated.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking sildenafil, it is especially important that your health care professional know if you are taking any of the following:
Alpha-blockers (medicine for high blood pressure—Sildenafil when taken together with an alpha-blocker medicine may cause very low blood pressure. Sildenafil doses above 25 mg should not be taken within 4 hours of taking an alpha-blocker medicine.
Bosentan (e.g., Tracleer)—May increase amounts of bosentan in the body
Cimetidine (e.g., Tagamet)
Erythromycin (e.g., E.E.S. or Ery-Tab)
Itraconazole (e.g., Sporanox)
Ketaconazole (e.g., Nizoral)
Mibefradil (e.g., Posicor)
Ritonavir (e.g., Norvir)
Saquinavir (e.g., Fortovase or Invirase)—These medicines may increase the unwanted effects of sildenafil, unless lower starting doses of sildenafil are used
Erectile dysfunction medicines—These medicines should not be used at the same time as sildenafil because the safety of using these medicines in combination has not been proven.
Nitrates, such as nitroglycerin (e.g., Nitrostat or Transderm-Nitro)—Sildenafil increases the lowering of blood pressure by nitrates too much and their use together is not recommended

Other medical problems—The presence of other medical problems may affect the use of sildenafil. Make sure you tell your doctor if you have any other medical problems, especially:
Age greater than 50 years or
Coronary artery disease or
Diabetes or
Hyperlipidemia (excess of lipids in the blood) or
Hypertension (high blood pressure) or
Low cup to disc ratio (“crowded disc”) or
Smoking—These conditions may increase risk for a serious eye problem called NAION.
Arrhythmias (irregular heartbeat) or
Coronary artery disease or
Heart attack, history of (within the last 6 months) or
High blood pressure or
Low blood pressure or
Stroke, history of (within the last 6 months)—Chance of problems occurring may be increased
Abnormal penis, including curved penis and birth defects of the penis—Chance of problems occurring may be increased
Bleeding problems or
Retinitis pigmentosa—Chance of problems occurring may be increased. It is not known if the medicine is safe for use in these patients
Conditions causing thickened blood or slower blood flow, including leukemia; multiple myeloma (tumors of the bone marrow); or polycythemia, sickle cell disease, and thrombocythemia (blood problems) or
Priapism (history of)—Although sildenafil does not cause priapism (erection lasting longer than 6 hours), patients with these conditions have an increased risk of priapism and it could occur while using sildenafil
Heart or blood disease—Sexual activity increases the heart rate and blood flow and can increase the chance of problems occurring for some patients who use any type of medicine, including sildenafil, that increases sexual ability
Kidney problems (severe) or
Liver problems (severe)—Chance of problems occurring may be increased. Lower starting doses may be used and doses increased as needed and as tolerated
NAION (serious eye condition) in one or both eyes, previously—May increase your chance of getting NAION again.
Pulmonary veno-occlusive disease (high blood pressure in the blood vessels of the lungs)—May make heart problems worse in patients with this serious condition

Description viagra

Sildenafil (sil-DEN-a-fil) belongs to a group of medicines that delay the enzymes called phosphodiesterases from working too quickly. The penis is one of the areas where these enzymes work. Sildenafil is used to treat men who have erectile dysfunction (also called sexual impotence).

By controlling the enzyme phosphodiesterase, sildenafil helps to maintain an erection that is produced when the penis is stroked. Without physical action to the penis, such as that occurring during sexual intercourse, sildenafil will not work to cause an erection.

Sildenafil is also used to treat the symptoms of pulmonary arterial hypertension. This is the high blood pressure that occurs in the main artery that carries blood from the right side of the heart (the ventricle) to the lungs. When the smaller blood vessels in the lungs become more resistant to blood flow, the right ventricle must work harder to pump enough blood through the lungs. Sildenafil helps by increasing the supply of blood to the lungs and reducing the workload of the heart.

This medicine is available only with your doctor's prescription, in the following dosage form(s):
Oral
Tablets (U.S.)

How should you take Viagra?

Taking Viagra approximately 1 hour before sexual activity works best for most men. Depending on how and when the drug works for you, an interval of one-half hour to as much as 4 hours may prove ideal.

--If you miss a dose...

Viagra is not for regular use. Take it only before sexual activity.

--Storage instructions...

Store at room temperature.

Why should Viagra not be prescribed?

Do not take Viagra if you are taking any nitrate-based drug, including nitroglycerin patches (Nitro-Dur, Transderm-Nitro), nitroglycerin ointment (Nitro-Bid, Nitrol), nitroglycerin pills (Nitro-Bid, Nitrostat), and isosorbide pills (Dilatrate-SR, Isordil, Sorbitrate). Combining Viagra with these drugs can cause a severe drop in blood pressure.

If Viagra gives you an allergic reaction, do not use it again.

Recommended dosage

Doses range from 25 milligrams to 100 milligrams, depending on the drug's effect. The usual dose is 50 milligrams. If you are over 65, have liver or kidney problems, or are taking erythromycin, ketoconazole, itraconazole, ritonavir, or saquinavir a dose of 25 milligrams may be sufficient. Your doctor will adjust the dosage if the drug is not working properly for you.

Take Viagra only before sexual activity. The manufacturer recommends a maximum of 1 dose per day (1 dose every 2 days for those taking ritonavir).

To avoid low blood pressure, do not take the 50-milligram or 100-milligram dose of Viagra within 4 hours of taking an alpha-blocking drug such as Cardura.

Possible food and drug interactions when taking Viagra

If Viagra is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Viagra with the following:

Other impotence remedies including Caverject and Muse
Alpha-blockers such as doxazosin (Cardura)
Amlodipine (Norvasc)
Cimetidine (Tagamet)
Erythromycin (E-Mycin, Ery-Tab, PCE)
Itraconazole (Sporanox)
Ketoconazole (Nizoral)
Nitrates such as Isordil, Nitro-Bid, and Nitro-Dur
Rifampin (Rifadin, Rimactane)
Ritonavir (Norvir)
Saquinavir (Fortovase, Invirase)

Special warnings about Viagra

If you have heart problems severe enough to make sexual activity a danger, you should avoid using Viagra. Use it cautiously--if at all--if you've had a heart attack, stroke, or life-threatening heart irregularities within the past 6 months. Be equally cautious if you have severe high or low blood pressure, heart failure, or unstable angina (crushing heart pain that occurs at any time).

If you take Viagra and develop cardiac symptoms (for example, dizziness, nausea, and chest pain) during sexual activity, do not continue. Alert your doctor to the problem as soon as possible.

If you have a condition that might result in long-lasting erections, such as sickle cell anemia, multiple myeloma (a disease of the bone marrow), or leukemia, use Viagra with caution. Also use cautiously if you have a genital problem or deformity such as Peyronie's disease. If an erection lasts more than 4 hours, seek treatment immediately. Permanent damage and impotence could result.

If you have a bleeding disorder, a stomach ulcer, or the inherited eye condition known as retinitis pigmentosa, use Viagra with caution. Its safety under these circumstances has not yet been studied.

To avoid low blood pressure, do not take the 50-milligram or 100-milligram dose of Viagra within 4 hours of taking an alpha-blocking drug such as Cardura.

Remember that Viagra offers no protection from transmission of sexually transmitted diseases, such as HIV, the virus that causes AIDS.

What should I avoid while taking diazepam?

Do not drink alcohol while taking diazepam. This medication can increase the effects of alcohol. Diazepam can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Avoid using other medicines that make you sleepy (such as cold medicine, pain medication, muscle relaxers, and medicine for seizures, depression or anxiety). They can increase some of the side effects of diazepam.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine. An overdose of diazepam can be fatal.

Symptoms of a diazepam overdose may include extreme drowsiness, confusion, muscle weakness, fainting, or coma.

What happens if I miss a dose?

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.

How should I take diazepam?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Your doctor may occasionally change your dose to make sure you get the best results from this medication.
Do not crush, chew, break, or open an extended-release capsule. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking or opening the pill would cause too much of the drug to be released at one time.

Measure the liquid form of diazepam with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Diazepam should be used for only a short time. Do not take this medication for longer than 4 months without your doctor's advice. Diazepam may be habit-forming and should be used only by the person it was prescribed for. Diazepam should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it. Contact your doctor if this medicine seems to stop working as well in treating your symptoms. Do not stop using diazepam suddenly without first talking to your doctor. You may need to use less and less before you stop the medication completely.

Your symptoms may return when you stop using diazepam after using it over a long period of time. You may also have seizures or withdrawal symptoms when you stop using diazepam. Withdrawal symptoms may include tremor, sweating, trouble sleeping, muscle cramps, stomach pain, vomiting, unusual thoughts or behavior, and seizure (convulsions).

To be sure this medication is not causing harmful effects, your blood and liver function may need to be tested on a regular basis. Do not miss any scheduled visits to your doctor.
Store diazepam at room temperature away from moisture, heat, and light.

Keep track of how many pills have been used from each new bottle of this medicine. Benzodiazepines are drugs of abuse and you should be aware if any person in the household is using this medicine improperly or without a prescription.

What should I discuss with my healthcare provider before taking diazepam?

Do not use this medication if you have narrow-angle glaucoma, or if you are allergic to diazepam or to other benzodiazepines, such as alprazolam (Xanax), chlordiazepoxide (Librium), clorazepate (Tranxene), lorazepam (Ativan), or oxazepam (Serax).

Before taking diazepam, tell your doctor if you are allergic to any drugs, or if you have:

glaucoma;

asthma, emphysema, bronchitis, chronic obstructive pulmonary disorder (COPD), or other breathing problems;

kidney or liver disease;

epilepsy or other seizure disorder;

a history of depression or suicidal thoughts or behavior; or

a history of drug or alcohol addiction.

If you have any of these conditions, you may not be able to use diazepam, or you may need a dosage adjustment or special tests during treatment.
Diazepam can cause birth defects in an unborn baby. Do not use diazepam without your doctor's consent if you are pregnant. Tell your doctor if you become pregnant during treatment. Use an effective form of birth control while you are using this medication. Diazepam may pass into breast milk and could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby. The sedative effects of diazepam may last longer in older adults. Accidental falls are common in elderly patients who take benzodiazepines. Use caution to avoid falling or accidental injury while you are taking diazepam. Do not give this medication to a child younger than 6 months old.

What is diazepam?

Diazepam is in a group of drugs called benzodiazepines (ben-zoe-dye-AZE-eh-peens). Diazepam affects chemicals in the brain that may become unbalanced and cause anxiety.

Diazepam is used to treat anxiety disorders, alcohol withdrawal symptoms, or muscle spasms.

Diazepam may also be used for purposes other than those listed in this medication guide.

What is the most important information I should know about diazepam?

Do not use this medication if you are allergic to diazepam or to other benzodiazepines, such as alprazolam (Xanax), chlordiazepoxide (Librium), clorazepate (Tranxene), lorazepam (Ativan), or oxazepam (Serax). This medication can cause birth defects in an unborn baby. Do not use diazepam if you are pregnant.

Before taking diazepam, tell your doctor if you have any breathing problems, glaucoma, kidney or liver disease, or a history of depression, suicidal thoughts, or addiction to drugs or alcohol.
Do not drink alcohol while taking diazepam. This medication can increase the effects of alcohol.

Avoid using other medicines that make you sleepy. They can add to sleepiness caused by diazepam.
Diazepam may be habit-forming and should be used only by the person it was prescribed for. Diazepam should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.

Precautions While Using Valium

If you will be taking a benzodiazepine regularly for a long time :
Your doctor should check your progress at regular visits to make sure that this medicine does not cause unwanted effects. If you are taking a benzodiazepine for convulsions (seizures), this is also important during the first few months of treatment.
Check with your doctor at regular visits to see if you need to continue taking this medicine.

If you are taking a benzodiazepine for epilepsy or another seizure disorder :
Your doctor may want you to carry a medical identification card or bracelet stating that you are taking this medicine.

If you are taking a benzodiazepine for insomnia (trouble in sleeping):
If you think you need this medicine for more than 7 to 10 days, be sure to discuss it with your doctor. Insomnia that lasts longer than this may be a sign of another medical problem.
You may have difficulty sleeping (rebound insomnia) for the first few nights after you stop taking this medicine.

Benzodiazepines may be habit-forming (causing mental or physical dependence) , especially when taken for a long time or in high doses. Some signs of dependence on benzodiazepines are:
A strong desire or need to continue taking the medicine.
A need to increase the dose to receive the effects of the medicine.
Withdrawal effects (for example, irritability, nervousness, trouble in sleeping, abdominal or stomach cramps, trembling or shaking) occurring after the medicine is stopped.
If you think you may have become mentally or physically dependent on this medicine, check with your doctor . Do not stop taking it suddenly.

If you have been taking this medicine in large doses or for a long time, do not stop taking it without first checking with your doctor . Your doctor may want you to reduce gradually the amount you are taking before stopping completely. Stopping this medicine suddenly may cause withdrawal side effects, including seizures. Stopping this medicine suddenly is most likely to cause seizures if you have been taking it for epilepsy or another seizure disorder.

This medicine will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. This effect may last for a few days after you stop taking this medicine. Check with your doctor before taking any of the above while you are taking this medicine .

If you think you or someone else may have taken an overdose of this medicine, get emergency help at once . Taking an overdose of a benzodiazepine or taking alcohol or other CNS depressants with the benzodiazepine may lead to unconsciousness and possibly death. Some signs of an overdose are continuing slurred speech or confusion, severe drowsiness, severe weakness, and staggering.

Before you have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of the metyrapone test may be affected by chlordiazepoxide.

If you develop any unusual and strange thoughts or behavior while you are taking this medicine, be sure to discuss it with your doctor. Some changes that have occurred in people taking this medicine are like those seen in people who drink alcohol and then act in a manner that is not normal. Other changes may be more unusual and extreme, such as confusion, agitation, and hallucinations (seeing, hearing, or feeling things that are not there).

This medicine may cause some people, especially older persons, to become drowsy, dizzy, lightheaded, clumsy or unsteady, or less alert than they are normally. Even if taken at bedtime, it may cause some people to feel drowsy or less alert on arising. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert .

Proper Use of Valium

For caregivers administering diazepam rectal gel :

For patients taking clorazepate extended-release tablets :
Swallow tablets whole.
Do not crush, break, or chew before swallowing.

For patients taking alprazolam, diazepam, or lorazepam concentrated oral solution :
Measure each dose carefully using the dropper provided with the medicine.
It is recommended that each dose be mixed with water, soda or soda-like beverages, or semisolid food such as applesauce or pudding, just before it is taken.
Take the entire mixture right away. It should not be saved to be used later.

For patients taking lorazepam sublingual tablets :
Do not chew or swallow the tablet. This medicine is meant to be absorbed through the lining of the mouth. Place the tablet under your tongue (sublingual) and let it slowly dissolve there. Do not swallow for at least 2 minutes.

For patients taking alprazolam oral disintegrating tablets :
Make sure your hands are dry. Just prior to taking the tablet, remove the tablet from the bottle. Immediately place the tablet on top of the tongue. The tablet will dissolve in seconds, and you may swallow it with your saliva. You do not need to drink water or other liquid to swallow the tablet. If you have split apart a tablet and only taken one half of the tablet, you should throw away the unused part of the tablet right away because it may not remain stable.

Take this medicine only as directed by your doctor . Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. If too much is taken, it may become habit-forming (causing mental or physical dependence).

If you think this medicine is not working properly after you have taken it for a few weeks, do not increase the dose . Instead, check with your doctor.

For patients taking this medicine on a regular schedule for epilepsy or other seizure disorder :
In order for this medicine to control your seizures, it must be taken every day in regularly spaced doses as ordered by your doctor . This is necessary to keep a constant amount of the medicine in the blood. To help keep the amount constant, do not miss any doses.

For patients taking this medicine for insomnia :
Do not take this medicine when your schedule does not permit you to get a full night's sleep (7 to 8 hours) . If you must wake up before this, you may continue to feel drowsy and may experience memory problems, because the effects of the medicine have not had time to wear off.

For patients taking flurazepam :
When you begin to take this medicine, your sleeping problem will improve somewhat the first night. However, 2 or 3 nights may pass before you receive the full effects of this medicine .

Dosing—The dose of benzodiazepines will be different for different patients. Follow your doctor's orders or the directions on the label . The following information includes only the average doses of benzodiazepines. If your dose is different, do not change it unless your doctor tells you to do so.

The number of capsules or tablets, or the amount of solution that you take, or the number of injections you receive, depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are taking benzodiazepines .

Before Using valium

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For benzodiazepines, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to benzodiazepines. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes. Certain benzodiazepine products may contain lactose, parabens, or soybean oil.

Pregnancy—Chlordiazepoxide and diazepam have been reported to increase the chance of birth defects when used during the first 3 months of pregnancy. Although similar problems have not been reported with the other benzodiazepines, the chance always exists since all of the benzodiazepines are related.

Studies in animals have shown that clonazepam, lorazepam, and temazepam cause birth defects or other problems, including death of the animal fetus.

Too much use of a benzodiazepine during pregnancy may cause the baby to become dependent on the medicine. This may lead to withdrawal side effects after birth. Also, use of benzodiazepines during pregnancy, especially during the last weeks, may cause body temperature problems, breathing problems, difficulty in feeding, drowsiness, or muscle weakness in the newborn infant.

Benzodiazepines given just before or during labor may cause weakness in the newborn infant. When diazepam is given in high doses (especially by injection) within 15 hours before delivery, it may cause breathing problems, muscle weakness, difficulty in feeding, and body temperature problems in the newborn infant.

Breast-feeding—Benzodiazepines may pass into the breast milk and cause drowsiness, difficulty in feeding, and weight loss in nursing babies of mothers taking these medicines.

Children—Most of the side effects of these medicines are more likely to occur in children, especially the very young. These patients are usually more sensitive than adults to the effects of benzodiazepines.

It is possible that using clonazepam for long periods of time may cause unwanted effects on physical and mental growth in children. If such effects do occur, they may not be noticed until many years later. Before this medicine is given to children for long periods of time, you should discuss its use with your child's doctor.

Older adults—Most of the side effects of these medicines are more likely to occur in the elderly, who are usually more sensitive to the effects of benzodiazepines.

Taking benzodiazepines for trouble in sleeping may cause more daytime drowsiness in elderly patients than in younger adults. In addition, falls and related injuries are more likely to occur in elderly patients taking benzodiazepines.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking or receiving benzodiazepines it is especially important that your health care professional know if you are taking any of the following:
Central nervous system (CNS) depressants (medicines that cause drowsiness)—The CNS depressant effects of either these medicines or benzodiazepines may be increased; your doctor may want to change the dose of either or both medicines
Fluvoxamine (e.g., Luvox) or
Nefazodone (e.g., Serzone)—Higher blood levels of benzodiazepines may occur, increasing the chance that side effects will occur; your doctor may want to change the dose of either or both medicines, or give you a different medicine
Itraconazole (e.g., Sporanox) or
Ketoconazole (e.g., Nizoral)—These medicines should NOT be used if you are taking a benzodiazepine.

Other medical problems—The presence of other medical problems may affect the use of benzodiazepines. Make sure you tell your doctor if you have any other medical problems, especially:
Alcohol abuse (or history of) or
Drug abuse or dependence (or history of)—Dependence on benzodiazepines may be more likely to develop
Brain disease—CNS depression and other side effects of benzodiazepines may be more likely to occur
Difficulty in swallowing (in children) or
Emphysema, asthma, bronchitis, or other chronic lung disease or
Hyperactivity or
Mental depression or
Mental illness (severe) or
Myasthenia gravis or
Porphyria or
Sleep apnea (temporary stopping of breathing during sleep)—Benzodiazepines may make these conditions worse
Epilepsy or history of seizures—Although some benzodiazepines are used in treating epilepsy, starting or suddenly stopping treatment with these medicines may increase seizures
Glaucoma, acute narrow angle—Benzodiazepines should NOT be used if you have this condition.
Glaucoma, open angle—Benzodiazepines can be used but your doctor should be monitoring your condition carefully.
Kidney or liver disease—Higher blood levels of benzodiazepines may result, increasing the chance that side effects will occur

Description valium

Benzodiazepines ((ben-zoe-dye-AZ-e-peens)) belong to the group of medicines called central nervous system (CNS) depressants (medicines that slow down the nervous system).

Some benzodiazepines are used to relieve anxiety. However, benzodiazepines should not be used to relieve nervousness or tension caused by the stress of everyday life.

Some benzodiazepines are used to treat insomnia (trouble in sleeping). However, if used regularly (for example, every day) for insomnia, they usually are not effective for more than a few weeks.

Many of the benzodiazepines are used in the treatment of other conditions, also. Diazepam is used to help relax muscles or relieve muscle spasm. Diazepam injection is used before some medical procedures to relieve anxiety and to reduce memory of the procedure. Chlordiazepoxide, clorazepate, diazepam, and oxazepam are used to treat the symptoms of alcohol withdrawal. Alprazolam and clonazepam are used in the treatment of panic disorder. Clobazam, clonazepam, clorazepate, diazepam, and lorazepam are used in the treatment of certain convulsive (seizure) disorders, such as epilepsy. The benzodiazepines may also be used for other conditions as determined by your doctor.

Benzodiazepines may be habit-forming (causing mental or physical dependence), especially when taken for a long time or in high doses.
