Nalfon or fenoprofen calcium is a nonsteroidal anti-inflammatory drug (NSAID) used for the treatment of various pain and inflammatory disorders such as osteoarthritis, rheumatoid arthritis, and gout. It comes under the class of propionic acid derivatives, which works by inhibiting the production of prostaglandins that cause pain, swelling, and inflammation. Uses: Nalfon is used for the symptomatic relief of mild-to-moderate pain and inflammation associated with osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, tendinitis, bursitis, gout, and menstrual cramps. It inhibits the synthesis of cyclooxygenase (COX), an enzyme involved in the production of prostaglandins, thereby reducing pain and inflammation. Dosage: The recommended dose of Nalfon for adults is 200 mg to 600 mg taken orally three to four times daily. The maximum daily dose should not exceed 3,200 mg per day. The dosage may vary depending on the severity of the pain and the condition being treated. It is recommended to take Nalfon with food or milk to reduce the risk of gastrointestinal side effects. Demographic: Nalfon is indicated for use in adults only. The safety and efficacy have not been established in children under the age of 18. It is contraindicated in patients with a history of allergic reactions to NSAIDs, aspirin, or other drugs with similar action. Side Effects: Like all NSAIDs, Nalfon has potential side effects. The most common side effects include gastrointestinal upset, nausea, vomiting, dizziness, headache, and abdominal pain. More severe side effects include increased risk of heart attack, stroke, or gastrointestinal bleeding. Patients who experience any unusual symptoms should immediately consult their healthcare provider. Interactions: Nalfon may interact with other drugs, supplements, or conditions. It is contraindicated in patients who are taking other NSAIDs, anticoagulants, or corticosteroids. It may also interact with lithium, methotrexate, and ACE inhibitors. Patients who are taking any medications should inform their healthcare provider to avoid potential drug interactions. Generic Options: Nalfon is available as a generic drug under the name fenoprofen calcium. It is comparable to the brand name drug in terms of efficacy, safety, and dosage.
