What is Viagra?

Viagra is a prescription drug that helps treat erectile dysfunction (ED) in men. Erectile dysfunction is a medical condition that makes you unable to have or keep an erection. It is under the recommendation for use only in a male of 18 years old or more. 

Viagra regulates the flow of blood in the penis and causes an erection if you get sexually aroused. It improves the ability to have and keep erections that result in successful sex and a safe experience.

Viagra helps in dealing with various issues of erectile dysfunction such as performance anxiety, stress, depression, high cholesterol, high blood pressure or heart disease, and most importantly, relationship issues.
