Question 6

Interpreting information

Riverside Surgery publishes these rules for repeat prescriptions.

Requests can be made online or in writing. Telephone requests are accepted only from patients aged 75 or over, or from patients registered as housebound.

Each medication review with a GP covers a patient's repeat prescriptions for 12 months. Once a review is overdue, one further repeat prescription can be issued; after that, no more can be issued until the review has taken place.
