No the prescription charge is set by the Government and you pay that charge for each item on the list.
The charge is set - if you want the pills you pay that amount, there is no alternative.
Each item can cover any prescribed item in a very large or very small quantity according to the prescription. This means that the patients perceived value of the charge can vary enormously - the actual cost of the medicine given out may vary from a few pence to hundreds of pounds. However, medical practitioners can prescribe a maximum three month supply of the medication in order for it to be covered under the NHS. If a medical practitioner wishes to prescribe a supply in excess of three months, the prescriber must write a separate, private prescription for the balance of the medication supply in excess of three months for which the patient must pay the actual price as charged by the pharmacist. Certain groups of patients are exempt from this charge, such as those over 60, under 16 (or under 19 if in full-time education), patients with certain medical conditions (who have a current medical exemption certificate), those on certain income related benefits and those with an HC2 certificate, which is issued if a patient can prove their income is under £8,000 per year. Prescription fees are currently £7.20 per item in England.
