Available Viagra dosages
Viagra is a prescription medicine containing Sildenafil, a Phosphodiesterase type 5 or (PDE5) inhibitor, that works by relaxing the blood vessels in the penile area. This improves blood flow and helps a man get and keep an erection when sexually aroused.
It’s important to know that Viagra does not increase sexual desire. It only helps improve erection when you are already sexually stimulated.
Viagra comes in different dosage strengths. The most common dosages available for Viagra are:
- 25 mg
- 50 mg
- 100 mg
Some generic versions of Sildenafil, known as generic Viagra, may also come in other strengths like 20 mg, 75 mg, or 120 mg. But, the three standard dosages mentioned above are the most widely prescribed and studied.
