The FDA has also approved a variety of nonprescription drugs that can help with ED, including Cialis, Levitra, and Stendra. These drugs can help patients with ED and other conditions by reducing or eliminating ED symptoms.

The Science Behind Viagra and Levitra

Viagra and Levitra are both FDA-approved for the treatment of erectile dysfunction. Viagra is an FDA-approved prescription drug, and Levitra is a generic version of the prescription drug.

Viagra and Levitra are both oral prescription medications that have been approved for the treatment of erectile dysfunction. They work by increasing the levels of cGMP in the blood and, consequently, producing an erection. These medications are typically taken as needed, and typically taken about 30 minutes to 1 hour before sexual activity.
