Overview
Viagra 100mg Tablet 4s contains sildenafil 100mg, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction in men. This is a Men’s Health medicine that helps achieve and maintain an erection sufficient for sexual activity when combined with sexual stimulation.
Sildenafil works by enhancing blood flow into the penis during sexual arousal. It does not cause an erection on its own – sexual stimulation is still required for the medicine to take effect.
How it Works
Sildenafil inhibits the PDE5 enzyme, which normally breaks down cyclic GMP (cGMP) in the smooth muscle of the penis. By blocking PDE5, sildenafil prolongs the action of cGMP, sustaining smooth muscle relaxation and increased blood flow into the penis in response to sexual stimulation.
Directions for Use
Take Viagra 100mg Tablet 4s on an empty stomach or after a light meal, as a high-fat meal can delay how quickly it starts to work. Sexual stimulation is still required for an erection to occur after taking this medicine.
Dosage
The usual starting dose of Viagra 100mg Tablet 4s is 50mg taken about 1 hour before anticipated sexual activity, which your doctor may adjust between 25mg and 100mg based on your response and tolerability. It should not be taken more than once daily.
Shelf Life
Use this product before the expiry date stated on the packaging. Do not use the medicine if the expiry date has passed.
