About Cialis

Cialis is considered a phosphodiesterase-5 (PDE5) inhibitor, which functions by relaxing blood vessels and muscles. Like any phosphodiesterase-5 inhibitor, this medication can only be used for erectile dysfunction. It is also ineffective against low libido because it will not increase testosterone.

Cialis is known to treat conditions including erectile dysfunction (ED) and symptoms of benign prostatic hyperplasia (BPH), a prostate condition that may cause problems with urination. Cialis is available only by prescription. It is available in a generic formulation as well as under different brand names, including Tadalafil ( generic Cialis )and Adcirca.

Cialis may be prescribed as a tablet. It’s always important to follow the specific instructions on your prescription medication, as they can vary based on the formulation and dosage you are prescribed.

If you are prescribed Cialis, be sure to complete the full course of the phosphodiesterase-5 inhibitor unless your doctor specifically tells you to stop.

If you don’t complete your prescription, the phosphodiesterase-5 inhibitor may not fully treat your erectile dysfunction.
