Cialis 20mg, containing tadalafil, treats erectile dysfunction (ED) by increasing blood flow to the penis, facilitating an erection. It’s also FDA-approved for treating benign prostatic hyperplasia (BPH), a condition causing urinary problems.
How Cialis 20mg Works
Tadalafil inhibits an enzyme called phosphodiesterase-5 (PDE5). This allows increased levels of cyclic guanosine monophosphate (cGMP), a molecule crucial for achieving and maintaining an erection. The effect begins within 30 minutes and can last up to 36 hours, significantly longer than many other ED medications. This longer duration is a key differentiator.
Important Considerations Before Use
Consult your doctor before using Cialis 20mg. They can assess your overall health and determine if it’s appropriate for you. This is especially important if you have heart conditions, high or low blood pressure, or liver or kidney problems. Interactions with other medications are possible, so disclose all current medications and supplements. Common side effects include headache, flushing, nasal congestion, and indigestion. Rare but serious side effects exist, warranting immediate medical attention if experienced.
Dosage and Administration
The recommended starting dose is usually 10mg, taken as needed, at least 30 minutes before sexual activity. Your doctor may adjust the dosage based on your individual needs and response. Follow the instructions on your prescription label precisely. Do not exceed the recommended dose.
