Does viagra have a 100 per cent success rate – what are the alternatives?
Mark L, London No. Viagra is not always 100 per cent effective There are three drugs of the Viagra group, Viagra, Cialis and Levitra. Each has its own merits. The time taken for each to be effective, the persistence of the effect (it is not always, but is sometimes, an advantage to have a long action) and the side effect profile varies. Not all these three drugs mix equally well with food or alcohol. If one of the three is not successful it is worth trying others. Viagra was the first on the market and is therefore perhaps is best known. Viagra, Cialis and Levitra are indicated for the treatment of men who have poor quality, inadequate erections for a physical reason, a poor blood supply to the penis, rather than any psychological cause. However they are always worth a trial even in those men who are unable to have any form of serviceable erection.
