What is Viagra?

Viagra (sildenafil) was the first drug approved by the US Food and Drug Administration (FDA) for treating erectile dysfunction. The active ingredient in Viagra, sildenafil, is also used to treat pulmonary arterial hypertension under the brand name Revatio.

Some healthcare providers might use it "off-label" to address conditions beyond its FDA-approved uses, such as female sexual arousal disorder and Raynaud’s phenomenon.

What is Cialis?

Cialis (tadalafil) is an FDA-approved medication for erectile dysfunction and benign prostatic hyperplasia (BPH), which is an enlarged prostate. It is also marketed as Adcirca for the treatment of pulmonary arterial hypertension. Similar to Viagra, some healthcare providers use it off-label to manage Raynaud’s phenomenon.

Viagra vs. Cialis: what is the difference?

The primary difference between Viagra and Cialis is their duration of effect. Cialis can remain effective for up to 36 hours, whereas Viagra is taken as needed and lasts for up to 6 to 8 hours.
