Do not drink Ethanol-containing beverages while taking Isoniazid, INH. Side effects from Isoniazid, INH can get worse. Ethanol may also decrease the actions of Isoniazid, INH by reducing the amount of INH in the body. If you develop fatigue, loss of appetite, unusual tiredness or weakness, or nausea/vomiting, contact your health care provider immediately. Also, some ethanol-based products also contain tyramine which can cause flushing, chills, or racing or pounding heartbeat if taken with Isoniazid, INH. These products include some beers (including reduced-ethanol and ethanol-free beer), red wines, sherry, hard liquor, and liqueurs. Avoid ethanol-containing beverages while taking Isoniazid, INH.
