The drug is, at present, subject to prescription control as it is listed in Schedule 1 of the Medicinal Products (Prescription and Control of Supply) Regulations 2003 as amended. No exemptions from prescription control are contained in Schedule 1 in respect of this drug and, therefore, it may not be supplied without prescription.
The drug is also listed in Schedule 3 of the Misuse of Drugs Regulations 1988 as amended. As a Schedule 3 controlled drug, additional controls apply to the prescription and supply of this drug over and above those applying to other prescription medicines; for example, prescriptions for this drug must primarily be in the prescriber's handwriting and are only valid for 14 days from the date of writing of the prescription.
