What Are the Differences Between Tadalafil and Cialis?

Tadalafil (Cialis®) is a medication used to treat ED, an enlarged prostate, or both. It’s known for its long-lasting effects and can be taken daily or as needed. Tadalafil is the active ingredient in the brand-name medication Cialis® and is used to treat erectile dysfunction (ED) and the symptoms of benign prostatic hyperplasia (BPH). Tadalafil works the same way as Cialis and has the same benefits and risks, according to the FDA.

17.2 Cardiovascular Considerations

Tell your doctor about all your current medicines, especially riociguat (Adempas). Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. Tadalafil works by relaxing the blood vessels and increasing blood flow to particular areas of the body, notably the penis. The drug is known for its long-lasting effects, allowing for more sexual spontaneity, as it can remain effective for up to 36 hours. It is typically taken as needed, but a lower-dose daily prescription is also available for continuous treatment. Common side effects of tadalafil include headaches, indigestion, back pain, and muscle aches, which typically resolve within a few days.
