Viagra, or sildenafil citrate, primarily works by increasing blood flow to the penis. This happens through the inhibition of an enzyme called phosphodiesterase-5 (PDE5).
Expect an erection firm enough for sexual intercourse within 30 to 60 minutes of taking the pill. The duration of effectiveness varies, but generally lasts for four to five hours.
Side effects, while not common for all, can include headache, facial flushing, nasal congestion, and visual disturbances. These are usually mild and temporary. Severe side effects are rare but require immediate medical attention.
Viagra isn’t a solution for all erectile dysfunction causes. Underlying health conditions, such as diabetes or heart disease, may need separate treatment. Consult your doctor to discuss whether Viagra is suitable for you, and to address any underlying medical issues.
Dosage varies depending on individual needs and your doctor’s recommendation. Always follow prescribed instructions precisely. Never exceed the recommended dose.
Interactions with other medications are possible. Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, to avoid potential complications.
Remember, Viagra is a prescription medication. Obtain it only through a licensed healthcare provider. Avoid purchasing from unverified online sources to ensure medication safety and efficacy.
