Viagra (Sildenafil) is used to treat male erectile dysfunction. Viagra can help you have an erection when sexual stimulation occurs. As a rule, Viagra is taken only when needed, in 30 minutes to 1 hour before anticipated sexual activity. You may take it up to 4 hours before sexual activity.
During sexual activity, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away.
Store Sildenafil at room temperature far from light, moisture and heat sources.
