Q: Is viagra available in liquid form? If yes, how is it different from the other form and how effective/harmful is it?

A:Please keep in mind that high blood pressure can cause erectile dysfunction (ED). Furthermore many drugs used to reduce blood pressure also cause ED. Viagra is a brand name and not the name of the medicine. The name of medicine is Sildenafil. In India it is sold under the brand names of Edegra and Penegra. It is available in capsule form only and not in a liquid form.
