General Information
Diazepam and the other drugs named above are benzodiazepines, used as antianxiety agents, anticonvulsants, or sedatives. Some are more suited to a specific role because of differences in chemical makeup that give them greater activity in a certain area or characteristics that make them more desirable for a certain function. Often, individual drugs are limited by the applications for which their research has been sponsored. Benzodiazepines directly affect the brain. In doing so, they can relax you and make you either more tranquil or sleepier, or can slow nervous system transmissions in such a way as to act as an anticonvulsant, depending on which drug you use and your dosage. Many doctors prefer the benzodiazepines to other drugs that can be used for similar effects because they tend to be safer, have fewer side effects, and are usually as, if not more, effective.
Cautions and Warnings
Do not take Diazepam if you know you are sensitive or allergic to it or to another benzodiazepine drug; including Clonazepam.
Diazepam can aggravate narrow-angle glaucoma. However, if you have open-angle glaucoma, you may take it. Check with your doctor.

In all of these conditions, the depressive effects of Diazepam may be enhanced and/or could be detrimental to your overall condition.
Diazepam should not be taken by psychotic patients, because it doesn’t work for them and can cause unusual excitement, stimulation, and rage.

Drug Interactions
- Diazepam is a central-nervous-system depressant. Avoid alcohol, other tranquilizers, narcotics, barbiturates, monoamine oxidase {MAO) inhibitors, antihistamines, and antidepressants. Taking Diazepam with these drugs may result in excessive depression, drowsiness, or difficulty breathing.
- Smoking may reduce the effectiveness of Diazepam by increasing the rate at which it is broken down by the body.
- The effects of Diazepam may be prolonged when taken with Cimetidine, oral contraceptives, Disulfiram, Fluoxetine, Isoniazid, Ketoconazole, Rifampin, Metoprolol, Probenecid, Propoxyphene, Propranolol, and Valproic Acid.
- Theophylline may reduce the sedative effects of Diazepam.
- If you take antacids, separate them from your Diazepam dose by at least 1 hour to prevent them from interfering with the passage of Diazepam into the bloodstream.
- Diazepam may increase blood levels of Digoxin and the chances for Digoxin toxicity.
- Levodopa’s effect may be decreased if it is taken with Diazepam.
- Phenytoin blood concentrations may be increased if taken with Diazepam, resulting in possible Phenytoin toxicity.
