What is Lactulose?

Lactulose is a nonabsorbable synthetic disaccharide composed of galactose and fructose linked by a lactase-resistant bond. Lactulose is not taken up in the small intestine but ferments in the colon to produce short-chain fatty acids, carbon dioxide, and hydrogen, lowering faecal pH. The sugar is undetectable in the stool of healthy volunteers given 20 g of lactulose medications daily. Some pass through the colon unchanged in higher doses.

Lactulose is a laxative that softens the stool and is available as a sweetened syrup. Adults take it orally to treat constipation, as it can help you regain control of your bowel movements and relieve constipation symptoms. But can you buy lactulose over the counter? Or do you need a prescription? Here we'll look at why it's necessary and what you'll need to get one.

Can it be purchased over the counter?

Lactulose is classed as a pharmacy medication, which means it can only be purchased from a pharmacy. This can be either in-store or online but under a pharmacist's supervision. This is different from prescription-only medicines (POM), requiring a physical prescription to obtain a specific medication. Since Lactulose is a pharmacy medicine, it may not be displayed openly on shelves. The pharmacist may also ask you questions before your purchase, including if you know how to use the medication, if you've used it before and your health status. They may inquire into your cause for buying the product to determine if you should seek advice from a doctor.
