バイアグラ 100 MG (VIAGRA 100 MG)

VIAGRA 100mg is a trusted and clinically proven ED medicine widely prescribed to men who find it difficult to get or maintain a firm and natural erection during sexual intercourse. This can affect confidence and even their relationships. When men take this medicine in the exact dose and schedule after a medical check-up, it effectively relaxes the blood vessels in the penis and allows more blood flow, which is responsible for giving a strong erection.

VIAGRA contains 100mg of Sildenafil as the main active ingredient, globally known as one of the safest and effective treatments for ED. This ED medicine belongs to a group of medicines called PDE5 inhibitors. This medication only works when men are sexually aroused. It is not a hormone or an aphrodisiac; it simply helps the body work better during sexual intimacy. So, always consult with your doctor before taking it.

How does VIAGRA work?

ED can happen at any age, when enough blood flow to the penis is restricted by an enzyme called PDE5. When men take VIAGRA in the exact dose, it blocks the activity of PDE5 and relaxes the blood vessels, allowing more blood to enter the penis and making it easier to get and maintain a strong erection when sexual stimulation is present.

The effect usually starts within 30 to 60 minutes of taking the tablet and may last for up to 4–5 hours.

Side Effects of VIAGRA

Like other ED medicines, VIAGRA also has some mild side effects. Not every man gets affected by them.

But some may experience:-

Most side effects usually go away on their own. But if they bother you or create trouble in your life, seek medical help immediately.
