Formula

Tablets = ordered dose ÷ strength of one tablet (same units)

How it is used

• Convert both numbers to the same unit first (1 g = 1,000 mg; 1 mg = 1,000 mcg).
• An answer that is not a whole or half tablet is a signal to recheck the order and the supply.

Key points

• Never split capsules, extended-release (XR, SR, CR) or enteric-coated tablets.
