Sildenafil - Overview

    Sildenafil is a medication used in the treatment of men suffering from erectile dysfunction. People who might need a sildenafil prescription can use Push Health to connect with a medical provider who can prescribe the medication to a nearby or delivery pharmacy when appropriate to do so.

    What Is Sildenafil?

    Sildenafil, marketed under brand names such as Revatio and Viagra, belongs to a class of medications known as phosphodiesterase-5 (PDE5) inhibitors. Similar to avanafil (Stendra), tadalafil (Cialis), and vardenafil (Levitra), sildenafil is used for treating erectile dysfunction in men, sildenafil is thought to work by improving the effect of a molecule known as nitric oxide (NO) in the penis during arousal. Sildenafil medication does this by inhibiting an enzyme known as phosphodiesterase type 5. By helping to sustain nitric oxide levels in the penis during arousal, sildenafil helps improve blood flow to tissues in the penis which helps with maintaining an erection.

    Sildenafil - Dosage and Cost

    Sildenafil prescription tablets are frequently prescribed as sildenafil 50 mg taken between 30 and 240 minutes before sexual activity. The sildenafil dosage may be lowered to sildenafil 20 mg or increased to sildenafil 100 mg depending on the health needs of the patient and the judgement of the prescribing medical provider. Sildenafil should not be taken more than once in a 24 hour period.

    Generic sildenafil tablets are considered affordable, generally costing under 50 cents per sildenafil 20 mg tablet at many pharmacies in the United States. Additionally, sildenafil coupons are sometimes available online or through the manufacturer. Occasionally, one's insurance plan will also contribute to covering the costs associated with getting sildenafil citrate prescription medication while buying sildenafil tablets at the pharmacy.
