Tablet Dosage Calculator

How to calculate tablet dosage?

The dosage calculation uses the ratio-proportion method to match the prescribed amount with the available tablet strength.

Formula: (Prescribed Dose) / (Tablet Strength) = Number of Tablets

Using the Tablet Dosage Calculator: an example

Consider a scenario where 500mg is prescribed using 250mg tablets twice daily for 5 days.

Step-by-step calculation:

• Divide 500mg by 250mg to get 2 tablets per dose
• Multiply 2 tablets by 2 times per day for a daily total of 4
• Multiply 4 daily tablets by 5 days for a 20-tablet total

Frequently Asked Questions

Can all tablets be split in half?

Only tablets with a score line should be split, as others may have special coatings for timed release.

What if the calculation results in a fraction?

Consult your healthcare provider; some medications allow for half-tablets, while others require a different strength.

Does this apply to liquid medication?

No, liquid medications require volume-based calculations (mg/mL) rather than simple unit counts.
