What is the main purpose of viagra?
The main purpose of Cialis (tadalafil) is to treat erectile dysfunction; it is also used for an enlarged prostate.
The main purpose of Cialis (tadalafil) is to treat erectile dysfunction by improving blood flow to the penis during arousal. It is also used for benign prostatic hyperplasia (an enlarged prostate) and, in a different form, for pulmonary hypertension. Its standout feature is a long duration of up to 36 hours. This article explains what Cialis is for.
It is a topic in our erectile dysfunction section.
Primarily for erectile dysfunction
Cialis is best known as an ED treatment. Like Viagra, it is a PDE5 inhibitor: it relaxes the blood vessels in the penis so that, with arousal, an erection is easier to achieve and maintain. This is its principal, everyday use.
The enlarged prostate use
Cialis is also approved to relieve the urinary symptoms of an enlarged prostate (BPH), such as a weak stream or frequent urination. Because many older men have both ED and BPH, a single daily low dose can address both at once, which is a notable advantage.
| Use | Note |
|---|---|
| Erectile dysfunction | main use |
| Enlarged prostate (BPH) | relieves urinary symptoms |
| Pulmonary hypertension | different brand/dose |
The long-duration advantage
What sets Cialis apart is its duration: up to 36 hours, far longer than Viagra's few hours. This has earned it the nickname "the weekend pill" and allows more spontaneity, since it need not be timed precisely before each occasion.
Daily versus on-demand
Cialis comes in an on-demand dose and a low daily dose. The daily option suits men who want continuous readiness or who are also treating BPH, while the on-demand dose suits less frequent use. A doctor advises which fits best.

Choosing Cialis or Viagra
Whether Cialis suits a man better than Viagra often comes down to lifestyle. Cialis's long duration favours spontaneity and works well as a low daily dose, while Viagra's shorter, predictable window suits planned activity. A doctor can weigh these alongside tolerability and any prostate symptoms to recommend the better fit.
