This question is about what a clinical pharmacist does and clinical pharmacist.
Yes, clinical pharmacists can write prescriptions. In this area, they are just as qualified as a medical doctor or psychiatrist. They can write these prescriptions in any professional context, be it at a hospital or a community pharmacy.
However, a clinical pharmacist does not physically give you your medication, nor can they override a medical doctor's prescription.
Having a clinical pharmacist diagnose you and prescribe your medication can save you a trip to the general physician's office. The main limitation is that pharmacists are not qualified to prescribe Schedule 8 drugs, such as oxycodone and morphine.
