Sildenafil can help men achieve far stronger and better long-lasting erections by enabling much better blood flow. Erections occur due to a chemical reaction in the body, which causes blood vessels to dilate near the penis. This happens so that blood can fill the smooth muscle (corpus cavernosum) in the penis, making it harder.
However, if you have ED, these vessels stay tight and don’t allow enough blood flow, meaning you will find it difficult to achieve or maintain an erection. PDE5 in the enzyme that causes these restrictions to the vessels. However sildenafil is a PDE5 inhibitor, which will stop this enzyme from working. This aids blood flow, giving you a much better, harder erection.
Possible side-effects can include nasal congestion, headaches, facial flushing, slight vertigo, a pounding heartbeat and blurred vision. However, side effects are rare, and most people don’t get any. Side effects may vary from one person to the next, as with any medication. You should always read the manufacturer’s Patient Information Leaflet (PIL) before taking this or any other medication.
