Cialis (tadalafil) is used for more than erectile dysfunction. It is also approved to treat the urinary symptoms of an enlarged prostate (benign prostatic hyperplasia) and, at a different dose and brand, pulmonary arterial hypertension. These extra uses come from the same vessel-relaxing action. This article explains tadalafil's wider role.
It belongs in our erectile dysfunction strategies section.
Treating an enlarged prostate
Daily low-dose tadalafil is approved to ease the urinary symptoms of benign prostatic hyperplasia (BPH) — such as a weak stream, urgency and frequency. Because BPH and ED often occur together in older men, one daily tablet can address both at once, which is convenient.
Pulmonary arterial hypertension
Under a different brand name and dose, tadalafil treats pulmonary arterial hypertension — high blood pressure in the arteries of the lungs. By relaxing those vessels, it eases the strain on the heart and improves exercise capacity. This is a serious condition managed by specialists.
| Use | How it helps |
|---|---|
| Erectile dysfunction | improves penile blood flow |
| Enlarged prostate (BPH) | eases urinary symptoms |
| Pulmonary hypertension | relaxes lung arteries |
Why one drug, several uses?
All these uses share a mechanism: tadalafil relaxes smooth muscle and widens blood vessels by inhibiting the PDE-5 enzyme. The same action helps erections, the prostate and bladder neck, and the lung arteries — just at different doses and for different goals.
Does that mean you can self-prescribe?
No. Each use has its own dose and medical assessment, and the same safety rules apply — never with nitrates, and caution with blood-pressure drugs. The convenience of a dual benefit (ED plus BPH) is decided by a doctor, not assumed. For a comparison with Viagra, see is Cialis better than Viagra.
The bottom line
Beyond ED, tadalafil treats enlarged-prostate symptoms and pulmonary hypertension, all through its vessel-relaxing action. These are doctor-directed uses with specific doses, never something to attempt by repurposing your own ED tablets. For what the pills look like, see colour and shape of Cialis.
