Niko Ds (naproxen Sodium)

# Niko Ds (naproxen Sodium) ## Overview Niko DS is a nonsteroidal anti-inflammatory drug (NSAID) providing analgesic, anti-inflammatory, and antipyretic effects by inhibiting COX-1 and COX-2 enzymes. Naproxen sodium is the salt form, which offers faster absorption than naproxen base. ## Primary Indications * Osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. * Acute musculoskeletal pain. * Dysmenorrhea. * Acute gout flares. * Migraine (acute treatment). ## Adult Dosing * **General Pain/Inflammation:** 275 mg to 550 mg every 12 hours. Maximum dose is 1,375 mg/day. * **Acute Gout:** 825 mg initially, followed by 275 mg every 8 hours until the attack subsides. * **Migraine:** 550 mg at onset; may repeat 550 mg once if needed (wait at least 30 minutes after the first dose). Maximum 1,100 mg/day. ## Pediatric Dosing * **Juvenile Idiopathic Arthritis (Age ≥2 years):** 10 mg/kg/day divided into two doses. Do not exceed 1,000 mg/day. * *Note: Dosing for other indications in children is often off-label or varies by institutional protocol; confirm with local pediatric formulary.* ## Dose Adjustments * **Renal Impairment:** Avoid in severe renal impairment (CrCl <30 mL/min). Use with caution in mild-to-moderate impairment; consider dose reduction. * **Hepatic Impairment:** Use with caution. Monitor closely; dose reduction may be required. * **Geriatric:** Use the lowest effective dose for the shortest duration due to increased risk of gastrointestinal (GI) toxicity and cardiovascular events. ## Contraindications * History of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. * Coronary artery bypass graft (CABG) surgery (perioperative pain management). * Active GI bleeding or peptic ulcer disease. * Severe heart failure or renal failure. ## Adverse Effects * **Common:** Dyspepsia, nausea, abdominal pain, dizziness, headache. * **Serious:** GI bleeding, ulceration, myocardial infarction, stroke, renal insufficiency, fluid retention/edema, and serious skin reactions (e.g., Stevens-Johnson syndrome). ## Key Drug Interactions * **Anticoagulants (e.g., Warfarin):** Increased risk of bleeding. * **Antiplatelets (e.g., Clopidogrel, Aspirin):** Increased GI toxicity/bleeding risk. * **SSRIs/SNRIs:** Increased risk of GI bleeding. * **ACE Inhibitors/ARBs/Diuretics:** Reduced antihypertensive effect and increased risk of acute kidney injury. * **Lithium/Methotrexate:** Increased plasma concentrations and risk of toxicity. ## Monitoring * Baseline and periodic CBC (hemoglobin/hematocrit). * Renal function (BUN/SCr) and electrolytes. * Blood pressure monitoring. * Signs and symptoms of GI bleeding (melena, hematemesis). ## Clinical Pearls * **GI Protection:** Consider a PPI (e.g., omeprazole) in patients with high GI risk factors (e.g., age >65, prior ulcer history, concomitant corticosteroids/anticoagulants). * **Administration:** Take with food or milk to decrease gastric upset. * **CV Risk:** All NSAIDs (except aspirin) carry a boxed warning for increased risk of serious cardiovascular thrombotic events. * **Timing:** Naproxen has a longer half-life than ibuprofen, allowing for twice-daily dosing, which may improve patient adherence. *** **Disclaimer:** This information is for educational purposes only.
