1.6.2 Stimulant laxatives

NHS England (NHSE) has published new prescribing guidance for various common conditions for which over-the-counter (OTC) items should not be routinely prescribed in primary care (quick reference guide). One of these conditions is infrequent constipation.

Many laxatives e.g. bisacodyl and senna, are cheap to buy and are readily available OTC along with advice from pharmacies. Some self-care medicines are available from shops and supermarkets. Please click here for further information, exceptions, and a patient leaflet.

Excessive use of stimulant laxatives can cause diarrhoea and related effects such as hypokalaemia; risk of electrolyte imbalance with prolonged use (in children).
