Your G.P. will issue a private prescription if the medicine he prescribes is not paid for by the N.H.S. for example certain travel vaccines, and malaria drugs.
Other Medical Practitioners such as Hospital Doctors or Consultants can’t write N.H.S. prescriptions, they will either write a private prescription or instruct your G.P. to write an N.H.S. prescription for the drugs they advise.
The big difference between the two is that, you must pay for private prescriptions.
Private prescriptions are priced according to guidelines set in place by the Pharmaceutical Society of Northern Ireland, and no V.A.T is charged.
