text: In the UK, pseudoephedrine is available over the counter under the supervision of a qualified pharmacist, or on prescription. In 2007, the MHRA reacted to concerns over diversion of ephedrine and pseudoephedrine for the illicit manufacture of methamphetamine by introducing voluntary restrictions limiting over the counter sales to one box containing no more than 720 mg of pseudoephedrine in total per transaction. These restrictions became law in April 2008. No form of ID is required.
