Neomycin sulfate 2.5 g by mouth every day for ten days. Available dosage is 500 mg tablets. How many tablets should be given per day?

Unit conversion and dosage calculation are being tested. You need 2.5 g by mouth each day, and each tablet is 500 mg. Convert 2.5 g to mg: 2.5 g = 2500 mg. How many 500 mg tablets fit into 2500 mg? 2500 ÷ 500 = 5. So you should give 5 tablets per day. The ten-day duration would total 50 tablets (5 per day × 10 days), but the daily dose remains five tablets.
