How old do you have to be to buy Calpol?

In the UK, there is no specific age restriction for purchasing Calpol, as it is an over-the-counter medication. However, it is generally advised that parents or guardians purchase it for children, as it is intended for use in young children. Pharmacists may recommend that the product should only be given to children over a certain age and weight. Always consult with a healthcare professional if unsure about its use.
