Listed prices are only an estimate, compiled from the Drug Tariff and other public pricing references, not an offer from any particular seller. Actual prices vary by pharmacy, pack and location, so check with the pharmacy for the number that applies to you. A price that seems oddly cheap next to this range should raise a red flag about who is actually selling it.

This medicine is available without a prescription: general sale list medicines are sold off the shelf, and pharmacy medicines are supplied after a quick word with the pharmacist.

Dextromethorphan is a general sale list (GSL) medicine under GSL rules in the UK. Read the pack leaflet first before buying, and check with a pharmacist about interactions. Some pack sizes of this product are kept behind the pharmacy counter and supplied by the pharmacist, so it helps to ask if you do not see it displayed.

About Dextromethorphan

Dextromethorphan is a cough suppressant, also called an antitussive, used to reduce coughing. Product-specific strengths, forms, generic availability and prescription status are not specified here.

Coughing can have many causes, so a pharmacist or doctor can help assess whether a dextromethorphan product is appropriate, especially when symptoms are persistent, severe or accompanied by other concerns. Different products may contain different ingredients and may be supplied in different forms, but no specific forms or strengths are listed here.

Dosage from the label

The label lists no available forms or strengths for dextromethorphan. The usual starting dose is not specified.

How Dextromethorphan works

Dextromethorphan is generally described as an antitussive, meaning a medicine that suppresses coughing. It acts on parts of the nervous system involved in the cough reflex, reducing the urge to cough.

This effect may lessen the symptom without treating every possible underlying cause of coughing. The precise product-specific mechanism, formulation and strength are not specified here, so a pharmacist can provide advice about a particular preparation and its ingredients.
