In the English National Health Service and NHS Wales the Blacklist (officially Schedule 1 to the National Health Service (General Medical Services Contracts) (Prescription of Drugs etc.) Regulations 2004) is a list published in Part XVIIIA of the NHS Drug Tariff denoting medicines and/or specific brands of medicines that cannot be prescribed on NHS medical prescriptions. If such a prescription is dispensed then NHS Prescription Services will refuse to refund the cost to the dispensing pharmacy.
Some brand name medicines on the blacklist can be dispensed against prescriptions for generic drugs (if the approved generic name is not itself included in the blacklist). For example, Calpol can be dispensed for a prescription for paracetamol suspension, but it is generally cheaper to dispense the generic form, and it is at the pharmacy's discretion to do otherwise.
Review of homeopathic treatments
Following a threat of legal action by the Good Thinking Society campaign group in 2015, the British government has stated that the Department of Health will hold a consultation in 2016 regarding whether homeopathic treatments should be added to the Schedule 1 list.
