Cialis is a prescription-only tablet used to treat erectile dysfunction and the symptoms of benign prostatic hyperplasia in adult men. It contains tadalafil, a phosphodiesterase type 5 inhibitor that improves blood flow to the penis during sexual stimulation, helping to achieve and maintain an erection. It can also relax smooth muscle in the prostate and bladder, which may improve urinary symptoms such as difficulty starting urination or a weak stream.

One of the key advantages of Cialis is its long duration of action. A single dose can remain effective for up to 36 hours, offering greater flexibility and spontaneity compared to shorter-acting treatments. It can be taken as needed before sexual activity or prescribed as a lower daily dose for continuous support, which may be particularly helpful for men managing both erectile difficulties and urinary symptoms.

Cialis works by blocking the PDE5 enzyme, enhancing the body’s natural response to sexual stimulation. It does not increase sexual desire and will not cause an erection without arousal. Most men tolerate it well, though side effects such as headache, indigestion, back pain, muscle aches, flushing or nasal congestion can occur and are usually mild.

Cialis should only be used under medical supervision. It is not suitable for men taking nitrate medications or certain recreational drugs, as this combination can cause a dangerous drop in blood pressure. Seek urgent medical attention if you experience chest pain, sudden vision or hearing changes, or an erection lasting longer than four hours. Always follow your prescriber’s instructions to ensure safe and effective use.
