What is diphenhydramine and naproxen?

Diphenhydramine is an antihistamine. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID).

Diphenhydramine and naproxen is a combination medicine used to treat occasional insomnia associated with minor aches and pains. This medicine is not for use in treating sleeplessness without pain, or sleep problems that occur often.

Diphenhydramine and naproxen is for use in adults and children at least 12 years old.

Diphenhydramine and naproxen may also be used for purposes not listed in this medication guide.

Naproxen can increase your risk of fatal heart attack or stroke. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG). Naproxen may also cause stomach or intestinal bleeding, which can be fatal.

Use this medicine exactly as directed. Taking too much diphenhydramine can lead to serious heart problems, seizures, coma, or death.
