Generic Viagra contains the same active ingredient as brand-name Viagra, sildenafil citrate. It works by increasing blood flow to the penis, making it easier to achieve and maintain an erection.
How Sildenafil Citrate Works
Sildenafil citrate inhibits an enzyme called phosphodiesterase-5 (PDE5). PDE5 normally breaks down cGMP, a chemical that relaxes blood vessel muscles. By blocking PDE5, sildenafil allows cGMP to build up, leading to vasodilation and increased blood flow to the penis. Sexual stimulation is still required to initiate the erection process; sildenafil simply enhances the body’s natural response.
Important Considerations
Generic Viagra is available only with a prescription. You should discuss your medical history with your doctor to determine if it’s safe for you. Side effects can include headache, flushing, and nasal congestion. Serious side effects are rare but possible. Always follow your doctor’s instructions and use as directed.
