Nalfon is used to treat osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. It helps relieve associated symptoms such as joint pain, swelling, stiffness, and decreased joint movement.
Nalfon is an NSAID that works by inhibiting cyclooxygenase (COX) enzymes, which are responsible for producing prostaglandins—chemicals that trigger inflammation, pain, and fever in the body.
Like all NSAIDs, Nalfon carries risks of gastrointestinal bleeding, cardiovascular events, and kidney problems. It should not be used during late pregnancy and may interact with blood thinners, other NSAIDs, and certain blood pressure medications. Patients should take it with food to reduce stomach upset.
