Difficulty splitting the tablet can occur, but changing the dose on your own may lead to unwanted effects or reduce its benefits. Try using a proper tablet cutter to get an even half, or ask your pharmacist if the same medicine is available in a lower-strength tablet so you do not need to split it. Keep the dose timing consistent at night and watch for any changes in memory, sleep, or behaviour if doses vary. Avoid giving a full tablet suddenly, as this may increase side effects like dizziness or stomach upset. Note any worsening confusion or unusual symptoms after dosing changes. Consult the prescribing doctor before adjusting the dose or switching to a different strength.

Follow your neurologist's guidance.
