Antiseizure Medications. Antiseizure drugs, such as carbamazepine (Tegretol) or divalproex sodium (Depakote) may be useful for reducing the requirements of a benzodiazepine. In two comparison 2002 studies, carbamazepine alone was superior to the benzodiazepine lorazepam in reducing withdrawal symptoms, including anxiety and sleep disturbances. Reduction in post-treatment drinking was also reported in one of the studies. Studies are also showing good results with divalproex. When used by themselves, however, they do not appear to reduce seizures or delirium associated with withdrawal.

Other Supportive Drugs. Beta-blockers, such as propranolol (Inderal) and atenolol (Tenormin), are sometimes used in combination with benzodiazepines. They slow heart rate and reduce tremors. They may also reduce cravings.

Note on Treating Alcohol Withdrawal with Alcohol. Some medical centers give patients alcohol to help with withdrawal. Experts do not recommend this approach. There is no evidence that this approach is safe or effective, while there is substantial evidence on the safety and effectiveness of benzodiazepines.

Specific Treatment for Severe Symptoms

Treating Delirium Tremens. People with symptoms of delirium tremens must be treated immediately. Untreated delirium tremens has a fatality rate that can be as high as 20%. Treatment usually involves intravenous anti-anxiety medications. It is extremely important that fluids be administered. Restraints may be necessary to prevent injury to the patient or to others.

Treating Seizures. Seizures are usually self-limited and treated with a benzodiazepine. Intravenous phenytoin (Dilantin) along with a benzodiazepine may be used in patients who have a history of seizures, who have epilepsy, or in those with ongoing seizures. Because phenytoin may lower blood pressure, the patient's heart should be monitored during treatment. Chlormethiazole, a derivative of vitamin B1, is presently used in Europe for reducing agitation and seizures.

Psychosis. For hallucinations or extremely aggressive behavior, antipsychotic drugs, particularly haloperidol (Haldol), may be administered. Korsakoff's psychosis (Wernicke-Korsakoff syndrome) is caused by severe vitamin B1 (thiamine) deficiencies, which cannot be replaced orally. Rapid and immediate injection of the B vitamin thiamin is necessary. One study reported benefits from a combination of fluvoxamine (Prozac) and clonidine (Catapres), a drug used for Tourette’s syndrome.
