The doctor or dentist may have prescribed you medication. If the centre you are visiting has an on-site pharmacy, you can conveniently fill your script there. The pharmacists have immediate access to the doctor to obtain clarity if required. Your doctor will explain your medication to you, but feel free to ask the pharmacist questions.
The pharmacist can provide you with extra information to help you understand your prescription and also give you advice about over the counter medicine. The pharmacist can provide you with the cost for the medication and suggest generic alternatives that may be more cost-effective. The choice is up to you.
