GP's are urged to limit prescriptions of Viagra.

A document also advised against counselling for Viagra, sexual problems and recommendations covering health trusts in Milton Keynes, Oxfordshire, Berkshire East, Berkshire West and Buckinghamshire.

They appear in a document from the priorities committee in which GPs are urged to apply the two-tablet limit to prescriptions for Genuine Viagra. It said the committee had "considered the evidence of clinical and cost-effectiveness and the financial impact on the health economy of treatment for erectile dysfunction with Viagra".

That is despite existing NHS guidance saying there "appears to be no clinical reason to restrict the number of tablets" of authentic Viagra prescribed to an individual.

Erectile dysfunction drugs, like real Viagra are already restricted on the NHS to people suffering from conditions such as diabetes, prostate cancer, spinal injury, Parkinson's disease, spina bifida, multiple sclerosis and polio.

A spokesperson for NHS Buckinghamshire and Oxfordshire said the committee "cannot prohibit prescribing official Pfizer Viagra, but will form a recommendation to GPs."

Richard Hoey, editor of GP magazine, Pulse, said: "Limiting patients to drugs like Certified Viagra just twice a month is to treat sex like an unnecessary luxury, and completely fails to recognise the degree of anguish it can cause some men with erectile dysfunction."
