Result

1/2 tablet

25 mg is 50% of a 50 mg tablet.

Arithmetic only, not medical advice. A pharmacist or prescriber must confirm the exact product can be split and that the prescribed dose is appropriate. Do not use the fraction to make a clinical decision.

How it works

  1. Enter the strength of one tablet and the prescribed dose, choosing the unit for each.
  2. The tool converts the units and divides prescribed dose by tablet strength.
  3. Use the exact result as an arithmetic cross-check, not as permission to split a tablet.

The optional formulation and scoring fields make the safety limitation visible, but they do not diagnose a product or approve tablet splitting. Check the label and ask a pharmacist or prescriber for the medication-specific answer.

FAQ

Is this medical advice?

No. This tool performs dose arithmetic only. Always confirm with a pharmacist or prescriber whether the exact medication and formulation can be split and whether the prescribed dose is appropriate.

Is my data uploaded anywhere?

No. The calculation runs in your browser and the entered values are not sent to a server.

How is the dose fraction calculated?

The tool converts the two entered units to a common basis, then divides the prescribed dose by the strength of one tablet. For example, 25 mg divided by 50 mg equals 0.5 tablet.

Can I split any tablet?

No. The result cannot establish that a tablet is safe to split. FDA guidance says to check the product labeling and consult a healthcare professional; many sustained-, controlled-, or timed-release products are not intended for splitting.
