Cialis

Also known as Tadalafil, Cialis is a drug that is popularly used to treat erectile dysfunction.

It is a yellow, almond-shaped, film-coated tablet that comes in three dosages; 5, 10, and 20 milligrams or mg.

It works almost the same with Levitra and Viagra. It improves blood pressure towards the penis, allowing men to have a better erection.

However, Cialis itself does not encourage sexual arousal. Instead, it needs sexual stimulation to take its effect.

It is recommended by doctors and health experts to be taken with caution and only under medical advice diagnosis.

Tadalafil was approved by the Food and Drug Administration or FDA in 2013 as a treatment for erectile dysfunction or ED. It is also a recognized cure for benign prostatic hyperplasia and pulmonary arterial hypertension.
