Cialis is a widely prescribed medication used to treat erectile dysfunction (ED). Understanding how it works, who should take it, and which medications or conditions may interact with it is essential for safe and effective use.
What Is Cialis?
Cialis (tadalafil) is a phosphodiesterase type 5 (PDE5) inhibitor used primarily to treat erectile dysfunction. It may also be prescribed for other conditions, depending on individual medical needs.
Unlike some ED medications, Cialis is known for its long-lasting effects, which can last up to 36 hours in some men.
How Does Cialis Work?
Cialis works by increasing blood flow to the penis during sexual stimulation. It relaxes blood vessels and improves circulation, making it easier to achieve and maintain an erection.
It’s important to note that it does not cause an erection on its own. Sexual arousal is still required for the medication to be effective.
Who Should Talk to a Doctor Before Taking Cialis?
Certain medical conditions may increase the risk of side effects or make Cialis unsafe. Always inform your doctor or pharmacist of your full medical history, especially if you have any of the following:
