Sildenafil under the name Viagra is used to treat erectile dysfunction (impotence) in men. Another brand of Sildenafil is Revatio, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. Don’t take Viagra while also taking Revatio, unless your pharmacist tells you to. Sildenafil may also be used for purposes not listed in this medication guide.
USAGE OF SILDENAFIL
Take exactly as prescribed by your pharmacist. Don’t take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Revatio is usually taken three times each day, about 4 to 6 hours apart. Viagra is usually taken only when needed, 30 minutes to 1 hour before sexual activity. You may take it up to 4 hours before sexual activity. Don’t take Viagra more than once per day. Viagra can help you have an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your pharmacist's instructions. 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 pharmacist right away. You could be having a serious side effect of Sildenafil. Store at room temperature away from moisture and heat.
