What is Genace?

Acetaminophen is a pain reliever and a fever reducer.

Aspirin is in a class of drugs called salicylates. It works by reducing substances in the body that cause pain and inflammation.

Caffeine is used in this product to increase the pain relieving effects of acetaminophen and aspirin.

Genace is used to treat pain from conditions such as headache (including migraine), muscle aches, menstrual cramps, arthritis, backache, toothaches, colds and sinus infections.

Genace may also be used for purposes other than those listed in this medication guide.
