Users of Naprosyn should avoid drinking alcohol while taking the drug, according to Drugs.com. Combining alcoholic beverages with Naprosyn or other products containing naproxen sodium, the generic equivalent of Naprosyn, can increase the user's risk for stomach bleeding.
Naprosyn is classified as a nonsteroidal anti-inflammatory drug, or NSAID, according to Drugs.com. Naprosyn works by causing a reduction of the hormones that cause pain and inflammation in the body. It is prescribed for an array of conditions that are characterized by pain and inflammation, including gout, bursitis, menstrual cramps, tendinitis, spondylitis, osteoarthritis and rheumatoid arthritis, among others.
Naprosyn is not for use in all patients, notes Drugs.com. Patients with allergies to aspirin or other NSAID drugs should avoid its use. The use of Naprosyn may cause an increase in the risk of stroke or heart attack. This is particularly true of those who are already diagnosed with heart disease or people who use the drug long term. The intestinal and stomach bleeding that may be caused by the drug can be severe or even life-threatening.
Naproxen sodium is sold under several brand names other than Naprosyn, including Aleve, Anaprox, Leader Naproxen Sodium, EC-Naprosyn, Anaprox-DS, Naprelan 375 and Midol Extended Relief, as of 2015.
