The liquid method, 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. Cut a reboxetine tablet to the portion you need with a pill cutter.
  2. Crush the piece between two spoons over a small plate.
  3. Stir it into a measured volume of water to make a known concentration. Shake or stir to disperse.
  4. Stir again immediately before drawing your dose — the active ingredient settles quickly.
  5. Measure your prescribed dose with an oral syringe and take it.
  6. Make a fresh liquid each day and discard any unused liquid in the rubbish.

About the liquid method

You crush or disperse a known strength of tablet into a known volume of water, then draw the fraction containing your target dose. Works for many SSRIs and some other psychotropics — not for modified-release formulations.

The dedicated sertraline · liquid page has a step-by-step worked example adapted from the RELEASE Toolkit; the same method applies to most immediate-release SSRI tablets.
