Before taking Generic Antabuse, tell your doctor if you have any of the following:
Do not drink alcohol while taking disulfiram. Flushing, fast heartbeats, nausea, thirst, chest pain, vertigo, and low blood pressure may occur when alcohol is ingested during disulfiram therapy.
Do not take disulfiram for at least 12 hours after drinking alcohol.
Reactions may occur from drinking alcohol for several weeks after you have stopped taking disulfiram.
Be aware of the alcohol content of other common products such as cough and cold medicines, mouth washes, tonics, sauces, vinegars, and other food products. Alcohol in these products can also cause a reaction.
