Before taking Nalfon

Nalfon can increase your risk of fatal heart attack or stroke, even if you don't have any risk factors. Do not use this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

Nalfon may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using this medicine, especially in older adults.

You should not use Nalfon if you are allergic to it, or if you have ever HAD an asthma attack or severe allergic reaction after taking aspirin or an NSAID.

Tell your doctor if you have ever had:

heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;

a heart attack, stroke, or blood clot;

You should not breastfeed while using Nalfon.
