Is DXM legal in United Kingdom?
- Legal status
- Over-the-counter cough medicine, NOT a controlled drug (not scheduled under the Misuse of Drugs Act 1971). Single-ingredient dextromethorphan (DXM) linctus is a Pharmacy (P) medicine sold under pharmacist supervision; the MHRA restricted paediatric OTC cough medicines to pharmacy supply (ages 6-12), while some lower-dose combination products remain General Sale List (GSL).
- Consequences if caught
- No Misuse of Drugs Act offence for DXM; supplying it outside the P/GSL framework is a medicines-regulatory offence under the Human Medicines Regulations 2012.
- If prescribed or medical
- Cough-suppressant status: OTC — Pharmacy (P) medicine for single-ingredient DXM, some GSL combinations; no prescription required.
- Documentation
- Travellers can buy DXM cough medicine at a UK pharmacy without a prescription; single-ingredient linctus is kept behind the pharmacy counter.
