Can I cut an extended release pill?
Last updated September 3, 2026.
No by default: cutting an extended-release pill destroys the slow-release structure and dumps the full dose at once, per NHS pharmacy guidance. Rare exceptions exist, a few scored modified-release tablets designed for halving, and some capsules whose beads can be swallowed uncrushed, but both are drug-specific facts, not guesses. The NHS patient rule: never crush, split, or open a medicine without medical advice. If the issue is size, dose, or cost, ask the pharmacist about lower strengths, liquids, or scored versions instead.
What to do
- Do not cut ER pills unless the pharmacist confirms that exact product allows it.
- Score line means designed to split; no line means no.
- Never crush capsule beads; swallow them whole if opening is allowed.
- Ask for a lower strength or liquid if the dose or size is the problem.
