Lansoprazole and naproxen
Generic Name: lansoprazole and naproxen (lan-SOE-pra-zole and na-PROX-en)
Brand Name: Prevacid NapraPAC
Lansoprazole and naproxen contains a nonsteroidal anti-inflammatory drug (NSAID). It may cause an increased risk of serious and sometimes fatal heart and blood vessel problems (eg, heart attack, stroke). The risk may be greater if you already have heart problems or if you take lansoprazole and naproxen for a long time. Do not use lansoprazole and naproxen right before or after bypass heart surgery.
Lansoprazole and naproxen may cause an increased risk of serious and sometimes fatal stomach ulcers and bleeding. Elderly patients may be at greater risk. This may occur without warning signs.
Lansoprazole and naproxen is used for:
Treating rheumatoid arthritis, osteoarthritis, or ankylosing spondylitis in certain patients with a history of gastric ulcer. It may also be used for other conditions as determined by your doctor.
Lansoprazole and naproxen is a combination package that contains an NSAID and a proton pump inhibitor (PPI). Exactly how the NSAID works is not known. It may block certain substances in the body that are linked to inflammation. NSAIDs treat symptoms of pain and inflammation. The PPI works by decreasing the amount of acid produced in the stomach. This decreases the risk of developing an ulcer from using an NSAID.
Do NOT use lansoprazole and naproxen if:
- you are allergic to any ingredient in lansoprazole and naproxen
- you have had a severe allergic reaction (eg, severe rash, hives, trouble breathing, growths in the nose, dizziness) to aspirin or an NSAID (eg, ibuprofen, celecoxib)
- you have recently had or will be having bypass heart surgery
- you have moderate to severe kidney problems
- you are in the last 3 months of pregnancy
- you are taking an HIV protease inhibitor (eg, atazanavir)
Contact your doctor or health care provider right away if any of these apply to you.
