Many excellent and important medicines are available Over The Counter (OTC) at pharmacies. They do not not need to be prescribed by a Doctor and indeed you can save yourself a lot of money as many are cheaper than the Prescription Charge. Pharmacists are highly trained in giving sensible advice about self-help for minor illness, please ask them or take a look here.
As part of the Self Care promotion by NHS England we have recommended you purchase a prescription for a condition which meets the criteria for this initiative. Please see the link below for more information & speak to your community pharmacist.
