Naprosyn (naproxen) is a nonsteroidal anti-inflammatory drug (NSAID) widely prescribed for its potent anti-inflammatory, analgesic, and antipyretic properties. As a trusted option in both acute and chronic pain management, it works by inhibiting the production of prostaglandins, chemicals in the body that cause inflammation, pain, and fever. Its extended duration of action allows for less frequent dosing compared to some other NSAIDs, providing sustained relief and improving patient compliance. Available in both prescription and over-the-counter forms, Naprosyn is a cornerstone in the treatment of various musculoskeletal and inflammatory conditions.

Common use
Naprosyn is commonly prescribed for the management of pain and inflammation in conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, juvenile arthritis, tendinitis, bursitis, and acute gout. It is also used for the relief of mild to moderate pain, including menstrual cramps (dysmenorrhea), headache, toothache, and musculoskeletal injuries. Additionally, it is indicated for the reduction of fever. Its broad anti-inflammatory action makes it suitable for both short-term symptomatic relief and long-term management of chronic inflammatory disorders.
Dosage and direction
For adults, the typical dosage for inflammatory conditions such as rheumatoid arthritis is 250 mg to 500 mg twice daily. The maximum daily dose should not exceed 1,500 mg for limited periods, though maintenance doses are often lower. For pain and dysmenorrhea, an initial dose of 500 mg may be followed by 250 mg every 6–8 hours as needed, not exceeding 1,250 mg on the first day and 1,000 mg on subsequent days. The oral suspension should be shaken well before use, and tablets should be taken with a full glass of water to reduce the risk of gastrointestinal upset. It is recommended to take Naprosyn with food or milk to minimize stomach irritation. Dosage adjustments are necessary for elderly patients or those with renal impairment.
Precautions
Patients should use the lowest effective dose for the shortest duration possible to minimize risks. Caution is advised in individuals with a history of gastrointestinal bleeding or ulceration, cardiovascular disease, hypertension, fluid retention, heart failure, or kidney impairment. Naprosyn may cause dizziness or drowsiness; patients should avoid driving or operating machinery until they know how the medication affects them. Prolonged use requires periodic monitoring of renal function, liver enzymes, and hemoglobin levels. Avoid alcohol consumption during treatment, as it may increase the risk of gastrointestinal bleeding. Use during pregnancy, especially in the third trimester, should be avoided due to potential risks to the fetus.
Contraindications
Naprosyn is contraindicated in patients with known hypersensitivity to naproxen, aspirin, or other NSAIDs. It should not be used in individuals who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Contraindications also include a history of prostaglandin-sensitive asthma, perioperative pain in the setting of coronary artery bypass graft (CABG) surgery, and severe heart failure. It is not recommended for use in patients with active peptic ulcer disease or gastrointestinal bleeding.
Possible side effect
Common side effects include nausea, heartburn, stomach pain, dizziness, headache, drowsiness, and mild fluid retention. Less frequently, it may cause ringing in the ears (tinnitus), blurred vision, skin rash, or itching. Serious side effects, though rare, can include gastrointestinal bleeding or perforation, hepatotoxicity, hypertension, heart attack, stroke, kidney injury, and severe skin reactions such as Stevens-Johnson syndrome. Patients should seek immediate medical attention if they experience symptoms such as black/tarry stools, vomiting blood, chest pain, shortness of breath, weakness on one side of the body, or slurred speech.
Drug interaction
Naprosyn may interact with several medications, including anticoagulants like warfarin (increased risk of bleeding), other NSAIDs or corticosteroids (increased risk of GI toxicity), ACE inhibitors or ARBs (reduced antihypertensive effect), diuretics (reduced efficacy and risk of renal impairment), lithium (elevated lithium levels), methotrexate (increased toxicity), and selective serotonin reuptake inhibitors (SSRIs; increased bleeding risk). Concomitant use with aspirin may diminish Naprosyn’s effectiveness and increase gastrointestinal risks. Always inform your healthcare provider of all medications, including over-the-counter drugs and supplements.
Missed dose
If a dose is missed, take it as soon as you remember. However, if it is almost time for the next scheduled dose, skip the missed dose and resume the regular dosing schedule. Do not double the dose to catch up. Consistent dosing is important for maintaining therapeutic levels, especially in chronic conditions, but occasional missed doses are unlikely to cause significant issues due to the drug’s long half-life.
Overdose
Symptoms of overdose may include drowsiness, heartburn, indigestion, nausea, vomiting, lethargy, epigastric pain, or rarely, more severe effects such as gastrointestinal bleeding, respiratory depression, coma, or acute renal failure. In case of suspected overdose, seek immediate medical attention or contact a poison control center. Treatment is supportive and may include gastric lavage, activated charcoal, and symptomatic care. Hemodialysis is not effective due to high protein binding.
Storage
Store Naprosyn at room temperature (20–25°C or 68–77°F), in a tightly closed container, and away from light, moisture, and heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. For the oral suspension, discard any unused portion after a certain period as indicated on the label—usually within a few weeks of opening.
