Viagra’s main side effect is an abrupt reduction in blood pressure, and may also produce “blue haze” vision in certain individuals. Such effects are more likely if taken with alcohol or after eating a high fat meal.

Viagra treats erectile dysfunction (ED) by increasing blood flow to your penis to help you attain and sustain an erection. Although FDA-approved to treat men who have ED, physicians may also prescribe it off-label (for other conditions).

Viagra may help female sexual issues; however, its effects have yet to be proven in studies conducted with female participants. But it has been shown to improve blood flow to female penises, potentially increasing sexual arousedness and making more open to having sexual relations sex sessions with partners. Although not approved specifically for use by female users.

The drug works by blocking certain chemicals that narrow or close blood vessels in your body, increasing levels of cyclic GMP to relax blood vessel in your penis and widen them so more blood flows in to form an erection.

Viagra could be harmful if you suffer from certain medical issues, such as heart or liver disease. Furthermore, taking Viagra alongside certain medicines (nitrates for heart disease or angina pain relief, for instance) could result in low blood pressure or other serious side effects; before beginning treatment with Viagra it’s wise to consult your physician prior to making decisions based solely on Viagra alone.
