Aleve contains 200 milligrams of naproxen and 20 milligrams of sodium, as stated on the official product website. The addition of sodium helps the active ingredient naproxen to dissolve more quickly.
Naproxen is a nonsteroidal anti-inflammatory drug that reduces pain- and inflammation-causing hormones, according to Drugs.com. Naproxen may provide relief from ankylosing spondylitis, tendinitis, bursitis, menstrual cramps, arthritis and other conditions. The ingredient can increase the risk of heart attack, stroke, stomach bleeding and intestinal bleeding. Patients should consult a doctor before taking naproxen if they have a history of heart problems, a history of stomach ulcers, asthma, a bleeding disorder or nose polyps. Patients should also speak with a doctor if they are pregnant or plan to become pregnant during the course of treatment.
Although Aleve does not include gluten ingredients, it may not be 100 percent gluten-free, as the manufacturing facility hosts other products that may contain gluten, according to the official product website. Aleve does not contain caffeine, aspirin or ibuprofen, but patients who have had an allergic reaction to other pain relievers should not take Aleve. The product Aleve PM includes 220 milligrams of naproxen sodium and 25 milligrams of diphenhydramine HCI, a sleep aid. Aleve-D is a non-drowsy formula with 120 milligrams extended-release pseudoephedrine HCL in addition to 220 milligrams of naproxen sodium.
