What is lansoprazole and naproxen (Prevacid NapraPAC)?
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing substances in the body that cause inflammation, pain, and fever.
Lansoprazole is a proton pump inhibitor. It decreases the amount of acid produced in the stomach.
The combination of lansoprazole and naproxen is used to treat symptoms of osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. The lansoprazole in this medication helps reduce the risk of stomach ulcers in people who may be at risk for them while receiving treatment with an NSAID.
Lansoprazole and naproxen may also be used for purposes not listed in this medication guide.
