All medicines are controlled by the Medicines Act 1968 and the Human Medicines Regulations (2012). The Medicines Act remains the primary legislation in force and the Human Medicines Regulations updated and clarified this. These set out the requirements for the legal sale, supply and administration of medicines.

These are medications which can be purchased from any licensed retailer, such as a supermarket.

There are still some controls in terms of the quantity that can be purchased, the strength of the medication and age limits of the purchaser.
