Naproxen 275mg

Naproxen Sodium 275mg – Quick Overview

Naproxen Sodium 275mg is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, inflammation, and fever associated with conditions such as arthritis, muscle pain, and menstrual cramps. It works by blocking enzymes that produce pain- and inflammation-causing chemicals in the body. Naproxen Sodium 275mg is available by prescription for acute pain dosing, and should be used at the lowest effective dose for the shortest time needed, as directed by a doctor.

Medical Supervision & Regulatory Status

Naproxen and naproxen sodium tablets received initial FDA approval in 1976. The 275mg strength (half of a 550 mg tablet) is used in prescription dosing regimens for acute painful conditions. Naproxen Sodium 275mg carries an FDA boxed warning for cardiovascular and gastrointestinal risks, so it requires physician guidance to determine appropriate use, dose, and duration.

Clinical Context

Pain and inflammation from conditions like osteoarthritis, rheumatoid arthritis, tendinitis, bursitis, and acute musculoskeletal injuries can significantly limit mobility and quality of life if not adequately managed. NSAIDs like naproxen are a mainstay of pain and inflammation control across many of these conditions.

Because the sodium salt of naproxen is more rapidly absorbed, naproxen sodium is often recommended for acute painful conditions when prompt onset of pain relief is desired, making the 275mg dose useful for flexible, as-needed dosing intervals.

Naproxen Sodium 275mg fits within the broader NSAID drug class, which doctors weigh against other pain-relief options based on a patient’s cardiovascular risk, GI risk, kidney function, and other health factors.

How Naproxen Sodium 275mg Works

Naproxen belongs to the nonsteroidal anti-inflammatory drug (NSAID) class. It works by inhibiting cyclooxygenase (COX-1 and COX-2) enzymes, which reduces the production of prostaglandins — chemical messengers responsible for pain, inflammation, and fever.

By lowering prostaglandin levels, Naproxen Sodium 275mg helps reduce swelling, stiffness, and pain associated with inflammatory and musculoskeletal conditions, while also helping to lower fever when present.

The recommended starting dose of naproxen sodium tablets is 550 mg followed by 550 mg every 12 hours, or 275 mg (one half of a 550 mg tablet) every 6 to 8 hours as required, allowing flexible dosing for acute pain relief under medical guidance.

What is Naproxen Sodium 275mg?

• Drug Class: Nonsteroidal anti-inflammatory drug (NSAID)
• Active Ingredient: Naproxen sodium (equivalent to 275mg naproxen sodium)
• Mechanism: Inhibits COX-1 and COX-2 enzymes to reduce prostaglandin-driven pain, inflammation, and fever
• Form: Oral tablet
• Dosing Frequency: Every 6–8 hours as needed, per prescribed regimen
• Regulatory Status: Prescription-only at this strength/regimen in the United States

Uses / Indications

• Osteoarthritis, Rheumatoid Arthritis, and Ankylosing Spondylitis: Helps reduce joint pain, swelling, and stiffness.
• Acute Painful Conditions (e.g., musculoskeletal injury, tendinitis, bursitis): Naproxen sodium tablets are recommended for management of acute painful conditions when prompt onset of pain relief is desired.
• Primary Dysmenorrhea: Used to relieve menstrual cramping pain.
• Mild to Moderate Pain and Fever: Used for general short-term pain and fever relief as directed by a doctor.

How to Use / Dosage

The initial total daily dose of naproxen sodium should not exceed 1375 mg, and thereafter the total daily dose should not exceed 1100 mg. The morning and evening doses do not have to be equal in size, and taking the drug more frequently than twice daily does not generally improve response. A doctor determines the exact regimen based on the condition being treated, symptom severity, and individual risk factors. Naproxen Sodium 275mg should be taken with food or a full glass of water to help reduce stomach upset, unless a doctor advises otherwise.

If a dose is missed, it should be taken as soon as remembered unless it is close to the next scheduled dose, in which case it should be skipped rather than doubled. Naproxen Sodium 275mg should not be used for longer than directed or at higher doses than prescribed without consulting a doctor, since prolonged or excessive use increases cardiovascular and gastrointestinal risk.

Side Effects

Most people tolerate short-term use of Naproxen Sodium 275mg reasonably well, though side effects can occur and should be discussed with a doctor.

Common side effects may include heartburn, stomach upset, nausea, headache, dizziness, and drowsiness.

Serious side effects can include gastrointestinal bleeding, ulceration, and perforation of the stomach or intestines, which can occur at any time during use and without warning symptoms, as well as increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can occur early in treatment and increase with duration of use.

Emergency Warning Signs — seek immediate medical attention if you experience:

• Chest pain, shortness of breath, or slurred speech (possible heart attack or stroke)
• Black, tarry, or bloody stools, or vomiting blood
• Severe stomach pain that doesn’t go away
• Sudden weight gain or swelling of the ankles, feet, or hands
• Yellowing of the skin or eyes (possible liver problems)
• Signs of a severe allergic reaction (swelling, rash, difficulty breathing)
• Unusual bruising or bleeding

Warnings & Precautions

Naproxen Sodium 275mg carries a boxed warning for increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal, and this risk may occur early in treatment and increase with duration of use. It is contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Elderly patients and those with a prior history of peptic ulcer disease or GI bleeding are at greater risk for serious gastrointestinal events.

Naproxen-containing products are not recommended for patients with moderate to severe or severe renal impairment (creatinine clearance below 30 mL/min). Concurrent use with other NSAIDs, aspirin, blood thinners (such as warfarin), corticosteroids, or SSRIs may increase the risk of GI bleeding, and use with certain blood pressure medications or lithium may alter their effectiveness or levels.

Use of NSAIDs during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus, so NSAIDs should be avoided in pregnant women starting at 30 weeks gestation. NSAIDs are also associated with reversible infertility, and withdrawal of naproxen may be considered in women who have difficulty conceiving. Breastfeeding should be discussed with a physician before use.

Who Should Not Use This Medication

• Patients with a known allergy to naproxen, aspirin, or other NSAIDs
• Patients undergoing or recovering from CABG surgery
• Patients with moderate to severe kidney impairment
• Patients with active or a history of recurrent GI ulcers or bleeding
• Patients in the third trimester of pregnancy (30 weeks gestation or later)
• Patients without a valid prescription or medical evaluation for this dosing regimen

Storage Instructions
