What is a Viagra pill, and what is it used for?
Viagra is the brand name for sildenafil, a medicine used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis during sexual stimulation.
How does sildenafil (Viagra) work?
Sildenafil relaxes blood vessels and improves blood flow. It also affects enzymes involved in erections, which is why it’s taken before sexual activity rather than continuously.
How do people typically take Viagra?
People usually take Viagra by mouth before sex. The right dose depends on the person’s age, other medicines, and health conditions, and should be set by a clinician.
What side effects are associated with Viagra pills?
Common side effects can include headache, flushing, upset stomach, nasal congestion, dizziness, and visual changes. Seek urgent help for signs of a serious reaction.
Who should not take Viagra (safety checks)?
A major safety issue is taking sildenafil with medicines containing nitrates (often prescribed for chest pain), because the combination can cause dangerous drops in blood pressure. People also need extra caution if they use certain heart or blood-pressure medicines.
How does Viagra compare to other ED pills?
Viagra (sildenafil) is one option in a class of ED drugs. Other brand-name options use different active ingredients (like tadalafil or vardenafil), which can differ in onset and duration for some patients.
