Cutting imipramine tablets into halves or quarters lets you reach smaller doses when your dose lands near a clean fraction. Enter your tablet strengths and target below — the calculator shows the closest achievable cut and how far it is from your target.

Cutting rarely lands exactly on a target dose — the calculator rounds to the nearest piece you can actually cut, so the achievable dose may differ from what you want. Quarters are approximate and can crumble. If the difference matters, ask your prescriber or pharmacist about a liquid or a compounded strength.

Cutting tablets, step by step

Method The maths above gives the number; these steps are the practical part. Adapted from the RELEASE Toolkit. Adjust the amounts to what your prescriber agreed.
  1. Check which tablet strengths you have, and enter them above.
  2. Use the calculator above to find the combination of pieces closest to your target.
  3. Cut along the score line where there is one; press the cutter straight down on a flat surface.
  4. Take the pieces together as your dose; store any remainder in a labelled container.

About cutting tablets

A pill cutter splits a tablet into halves or quarters. Halves are reliable; quarters can crumble or split unevenly. Because you can only cut so finely, the calculator rounds to the nearest piece you can actually cut — so the achievable dose often won't match your target exactly. It shows you the difference both ways (just below and just above) so you and your prescriber can decide whether that's close enough, or whether a liquid or compounded strength would be more accurate.

You can enter more than one strength if you have them. Diazepam, for example, comes as 5 mg and 2 mg tablets — many people hold both — so the calculator works out the doses you can make by combining cut pieces of each.

Don't cut modified-release, enteric-coated or film-coated tablets — the release profile or absorption changes. If your target dose doesn't fall close to a clean cut, the liquid or bead method is usually more accurate.
