What Is Generic Cialis & How Does It Work?

If you or someone you love is managing generic Cialis for sale, understanding the medication is the first step toward better sexual health. Generic Cialis contains tadalafil, a PDE5 inhibitor approved by the FDA for treating erectile dysfunction (ED). It works by relaxing blood vessels in the penis, allowing increased blood flow during sexual stimulation. Unlike some ED drugs that last only 4–6 hours, tadalafil stays active for up to 36 hours — giving couples more spontaneity.

Tadalafil is also approved for treating benign prostatic hyperplasia (BPH) and, in some formulations, pulmonary arterial hypertension. Available in 2.5 mg, 5 mg, 10 mg, and 20 mg tablets, it can be taken as needed or as a once-daily low dose. The flexibility of dosing makes it one of the most prescribed erectile dysfunction medications in the United States.
