ED treatment is easily treated through the UK's NHS from your GP if you are healthy enough. A man suffering from ED should get a medical history and physical check as some medical problems make most ED treatments dangerous. Heart disease especially. Especially if you take nitroglycerin. If you have any certain medical conditions, please tell me as the pills would be cheaper if you have, for example, multiple sclerosis, Parkinson's, spina bifida.
Otherwise, 4 tabs cost between £17 and £30 for those without the conditions needed for an NHS prescription.
All warnings given with these Viagra-type pills should be duly noted--like chest pain or faintness and prolonged erection. There are other drug treatments like alprostadil sticks (inserted into the penis opening) available from your GP's prescription as well as other non-drug treatments like the Post-T-Vac, which can be purchased online.
This is advice only and not to replace local medical care.
