Naproxen IR dose is

Naproxen IR dose is

• A. 250-500 mg PO BID
• B. 500-750 mg PO daily
• C. 750-1000 mg PO daily
• D. 125-250 mg PO QID

Answer: (A)

Naproxen IR is dosed in divided, moderate per-dose amounts for adults, typically 250-500 mg every 6–8 hours as needed, with a maximum of about 1250 mg per day. The option that fits this practice is 250-500 mg taken twice daily, which provides about 500-1000 mg per day—within the usual safety range and spaced to maintain relief throughout the day. This reflects the common real-world approach to NSAID analgesia, balancing efficacy with GI and renal safety. Other dosing patterns either assign a daily total that doesn’t align with the typical per-dose amount or require more frequent administration than is standard for naproxen IR, making them less consistent with how the medication is usually used.
