Tablet count and pill splitting calculator

Your dose is in milligrams but the tablets come in a different strength? See how many tablets make up each dose and how many you need in total.

Only split a tablet if your pharmacist says it can be split. Some tablets must be swallowed whole.

Arithmetic only, not medical advice. Your doctor or pharmacist sets your doses.

How it works

The dose divided by the strength of one tablet gives the tablets in each dose. Both are converted to milligrams first, so a dose in micrograms and a tablet labelled in milligrams still line up (1 mg is 1,000 mcg and 1 g is 1,000 mg). Tablets per dose times doses per day times days gives the total, rounded up to whole tablets.

If the answer is a half, you need half tablets. Many tablets have a score line for this, but a score line does not always mean a tablet is meant to be split. Slow-release and coated tablets often must not be cut. Your pharmacist can tell you, and can often supply a strength that avoids splitting altogether.

Your phone can count the tablets

In Cadence you set a dose as a number of tablets with their strength, such as 1.5 tablets of 500 mg. Each dose you log, including half doses, comes off your supply, and you get a reminder before the pack runs low.
