In certain situations, your pharmacist can extend your prescription for a period of time. Your pharmacist can replace, extend and renew some existing prescriptions; issue a new prescription for pre-existing conditions in an emergency situation; alter prescriptions to accommodate special needs; change the drug dosage/formulation and make therapeutic substitutions.
Increased pharmacist involvement will actually help monitor which patients should be referred to physicians instead of patients self-treating indefinitely. This will help reduce the risk for patients. Please check with your pharmacist for details.
