Viagra

The active ingredient Sildenafil Citrate belongs to a group of medicines known as PDE5 inhibitors. They work by relaxing blood vessels, allowing more blood flow to the Penis.

At least two-thirds of men are reported to have improved erections after using sildenafil. The brand name Viagra is so popular that it is a household name, widely regarded as the ‘go to’ medication for ED.
Sildenafil is best taken on an empty stomach and alcohol should be avoided, both of which can decrease the effectiveness of the medication.

Many men report mild to no side effects at all, but as with all medicines, sildenafil can potentially cause side effects which include headache, nausea and dizziness, nasal congestion, hot flushes, indigestion, palpitations and blurred vision.
