General Use

The active ingredient in Viagra is Sildenafil Citrate.
Sildenafil Citrate influences the body’s response to sexual stimulation by promoting smooth muscle relaxation through the release of nitric oxide — a natural chemical released during sexual arousal. This relaxation enhances blood flow to specific regions of the penis, resulting in an erection.
Sildenafil Citrate is primarily used to treat erectile dysfunction (ED) in men and pulmonary arterial hypertension.
It may also be prescribed for other conditions not mentioned in this guide.

 

Dosage and Administration

The typical recommended dose is 50 mg, taken approximately 30 minutes to 1 hour before sexual activity.
Do not take Viagra more than once within a 24-hour period.
Consuming a high-fat meal may slow down the drug’s effectiveness.
Avoid eating grapefruit or drinking grapefruit juice while taking Sildenafil Citrate, as it may interfere with how the medication works.
