Sildigra 100, which contains sildenafil citrate as its active ingredient, typically starts working within 30 to 60 minutes after ingestion. However, the exact onset of action can vary from person to person based on factors such as metabolism, overall health, and whether the medication is taken on an empty stomach or with food.

Here's a general timeline for how Sildigra 100 works:

Onset of Action: Sildigra 100 mg begins to take effect within 30 to 60 minutes after ingestion. During this time, the body absorbs the sildenafil citrate, and the medication starts to exert its vasodilatory effects on the blood vessels in the penis.

Peak Effectiveness: The peak effectiveness of Sildigra 100 is typically reached within 1 to 2 hours after ingestion. This is when the medication's ability to increase blood flow to the penis and facilitate a firm erection is at its highest.

Duration of Action: Sildigra 100 can remain effective for up to 4 to 6 hours after taking the dose. During this time, men may experience improved erectile function and the ability to achieve and maintain erections suitable for sexual activity.
