Consult your doctor before starting Cialis. This medication requires a prescription and a discussion of your medical history to ensure safe and effective use.
Cialis, the brand name for tadalafil, is a medication primarily used to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). It works by increasing blood flow to the penis, aiding in achieving and maintaining an erection. For BPH, it relaxes the muscles in the prostate and bladder, improving urinary flow.
How Cialis Works
Tadalafil inhibits the enzyme phosphodiesterase-5 (PDE5), which regulates blood flow in the penis. By blocking PDE5, Cialis allows for increased blood flow upon sexual stimulation, resulting in an erection.
Cialis Dosage and Administration
The recommended starting dose for ED is 10 mg taken as needed, at least 30 minutes before sexual activity. For BPH, the usual dose is 5 mg once daily. Your doctor will determine the appropriate dose based on your individual needs and health status. Never exceed the prescribed dosage.
Possible Side Effects
Common side effects can include headache, flushing, nasal congestion, muscle aches, and indigestion. More serious side effects, though rare, include vision changes, hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience any serious side effects.
Cialis and Other Medications
Certain medications can interact with Cialis. Inform your doctor about all medications, including over-the-counter drugs and supplements, you are currently taking. This is crucial to avoid potentially harmful interactions.

Cialis may not be suitable for individuals with certain health conditions, such as heart problems, low blood pressure, or severe liver or kidney disease. Open communication with your doctor is key.
