How should I take Aceta-Gesic (acetaminophen and diphenhydramine)?
Use this medication exactly as directed on the label, or as prescribed by your doctor. Do not take this medicine for longer than recommended. Cold or allergy medicine is usually taken only for a short time until your symptoms clear up.
Do not take more of this medication than is recommended. An overdose of acetaminophen can damage your liver or cause death.
Stop taking the medicine and call your doctor if you still have a fever after 3 days, or you still have pain after 10 days (or 5 days if treating a child). Also call your doctor if your symptoms get worse, or if you have any redness or swelling.
If you need surgery or medical tests, tell the doctor ahead of time if you have taken this medicine within the past few days.
Store at room temperature away from moisture and heat.
