Anxiety, tension, fatigue, agitation, and withdrawal symptoms of alcoholism; also prescribed for irritable bowel syndrome and panic attacks.
General Information
Chlordiazepoxide is a member of the group of drugs known as benzodiazepines.
Benzodiazepines work by a direct effect on the brain. They can relax you and make you more tranquil or sleepier, or they can slow nervous system transmissions in such a way as to act as an anticonvulsant. Many doctors prefer benzodiazepines to other drugs that can be used to similar effect because they tend to be safer, have fewer side effects, and are usually as effective, if not more so.
Cautions and Warnings
Do not take chlordiazepoxide if you are allergic or sensitive to any of its ingredients or to another benzodiazepine, including clonazepam.
Chlordiazepoxide can aggravate narrow-angle glaucoma, but you may take it if you have open-angle glaucoma and are receiving therapy for it.
Other condkjo(\SiVN\,NhjCb chlordiazepoxide should be used with caution are severe depression, especially with suicidal tendencies, severe lung disease, sleep apnea (intermittent cessation of breathing during sleep), liver disease, drunkenness, and kidney disease.
Chlordiazepoxide should not be taken by psychotic patients because it is not effective for them and can trigger unusual excitement, stimulation, and rage. It has also produced similar reactions among hyperactive and aggressive pediatric patients.
Chlordiazepoxide is not intended for more than 3-4 months of continuous use. Your condition should be reassessed before continuing chlordiazepoxide beyond that time.
Chlordiazepoxide may be addictive. Drug withdrawal may develop if you stop taking it after only 4 weeks of regular use, but is more likely after longer use. It may start with anxiety and progress to tingling in the hands or feet, sensitivity to bright light, sleep disturbances, cramps, tremors, muscle tension or twitching, poor concentration, flu-like symptoms, fatigue, appetite loss, sweating, and changes in mental state.
Dosage of chlordiazepoxide should be decreased gradually over 4-8 weeks after prolonged use.

Taking chlordiazepoxide with these drugs may result in excessive depression, tiredness, sleepiness, breathing difficulties, or related symptoms.

taken with cimetidine, contraceptive drugs, disulfiram, flu-
oxetine, isoniazid, ketoconazole, metoprolol, probenecid,

•    Theophylline may reduce chlordiazepoxide’s sedative effects.

Acamprosate (ah-CAM-pro-sate)
Brand Name Cameral
Type of Drug
Synthetic neurochemical similar to the amino acid homotaurine.
Prescribed For Alcoholism.
General Information
Acamprosate is used to help alcoholic patients stay alcohol-free after they have stopped drinking. Unlike other drugs used to help people stay away from alcohol, it does not cause people to have a physical reaction to alcohol. Acamprosate restores the balance between two chemical systems in the brain, glutamate and GAGA, that are known to become unbalanced in alcoholics, but its exact action is not known. It may reduce alcohol craving. Acamprosate should be part of a program that includes counseling and support, and it should be started as soon as possible after alcohol withdrawal and continued even if the patient starts drinking again. This medication has not been proven to help patients if they are still drinking when they start treatment. Acamprosate has not been studied in patients who abuse other substances together with alcohol. Tolerance or addiction has not developed with acamprosate. It passes out of the body through the kidneys.
Cautions and Warnings
Do not take acamprosate if you are allergic or sensitive to any of its ingredients or if you have severe kidney disease. People with moderate kidney disease require a lower dosage of acamprosate.
