People who have lots of prescriptions may be able to buy their medicines more cheaply by using a Prepayment of Prescription Charges certificate (approx 90 per year ask at the pharmacy, Health Centre or Post Office). Some medicines can be bought more cheaply over the counter than on prescription. Some people are entitled to free prescriptions (e.g. those who are unable to go out without help from another person or who receive Income Support or Disability Working Allowance), for more details contact:
