On the NHS, Viagra or generic Sildenafil are not routinely prescribed. A GP will assess your suitability and the underlying causes of erectile dysfunction (ED).
If you meet the the qualifying criteria as set out by the NHS prescribing guidelines, you will be eligible to receive a maximum of 4 tablets per month.
NHS treatment is generally reserved for patients whose erectile dysfunction is linked to certain health conditions, treatments, or surgeries.
Medical conditions that allow Viagra on an NHS prescription include:

Generic Sildenafil is the NHS-approved version of Viagra and works the same way by improving blood flow to help with erectile dysfunction.
It can be obtained through a GP prescription after a consultation to assess your health and the cause of your symptoms.
Not everyone will be eligible to get a prescription for Sildenafil on the NHS, as you need to meet certain criteria.
In most cases, private clinics or online licensed pharmacies are the route for most men to obtain this medication. This is due to less restrictions on the quantities of tablets that private prescribers can prescribe.

Even if you meet the criteria to receive ED treatment on the NHS, Viagra is rarely prescribed, because generic Sildenafil is much cheaper, and just as effective.
Branded Viagra can still be obtained through private prescriptions or online clinics, where patients pay the full cost. Like the generic version, it requires a consultation to ensure it’s safe and suitable.
Just like generic Sildenafil, if your doctor is willing to prescribe Viagra on an NHS prescription, you will need to meet certain criteria.
