Erectile dysfunction (ED) is a common problem that affects millions of men worldwide. It can affect the ability to achieve or maintain an erection firm enough for satisfactory intercourse. Occasional ED can be caused by stress or fatigue, but if it persists, it may be an indication of an underlying health issue that requires medical attention.

In this comprehensive guide, you will learn the difference between Sildenafil and Tadalafil, compare their effectiveness, duration, dosage and side effects and what to discuss with your healthcare provider when choosing the right ED medication.

What Is Sildenafil
Sildenafil is one of the first oral medications approved for the treatment of erectile dysfunction. It is widely known under the brand name Viagra, but there are many generic versions available.
Sildenafil works by relaxing the blood vessels in the penis. This helps to increase blood flow during sexual excitement, which helps a man get and keep an erection. The medication does not cause an erection automatically. It still needs sexual stimulation for it to function.
How Sildenafil Works
When a man becomes sexually aroused, the body releases nitric oxide that helps relax smooth muscles and dilate blood vessels in the penis. Sildenafil helps in this natural process by blocking the PDE5 enzyme. This enables the blood vessels to remain relaxed for longer.
