Since antabuse is a prescribed drug, your doctor or pharmacist should already be aware of any possible drug interactions you may experience, and may be monitoring them for you. It is important that you do not start, stop, or change the dosage of any medicine while on antabuse treatment, before consulting with your doctor. Also, if you are to going to have a surgery of any sort, be sure to clarify with your doctor that you are taking antabuse.

Antabuse must not be used with the following drugs because of very serious drug interactions that may happen: any alcohol-containing products (cough and cold medicines, aftershave, lotions, perfume, etc.), amprenavir oral solution (protease inhibitor used in HIV infection treatment), metronidazole (medication commonly used in the treatment of infections initiated by susceptible organisms).

Before you start taking antabuse, inform your doctor if you are using any of the medications listed above.

Before using antabuse, tell your doctor or pharmacist of all prescribed and nonprescriptional/herbal products you use, especially of: amitriptyline, any “blood thinning” drugs (warfarin), certain seizure medications (phenytoin or fosphenytoin), theophylline, isoniazid.
