Cialis (tadalafil) treats erectile dysfunction (ED) by increasing blood flow to the penis. This happens through the inhibition of phosphodiesterase type 5 (PDE5). PDE5 breaks down cyclic guanosine monophosphate (cGMP), a molecule crucial for penile erection. By blocking PDE5, Cialis allows cGMP levels to rise, relaxing blood vessel muscles and increasing blood flow.
How Cialis Differs from Other ED Medications
Unlike some other ED medications that act quickly, Cialis offers a longer duration of action. Its effects can last up to 36 hours, earning it the nickname “the weekend pill”. This extended duration allows for more spontaneity.
Understanding Cialis Dosage and Administration
Cialis comes in various dosages (2.5mg, 5mg, 10mg, and 20mg), prescribed based on individual needs and health conditions. It’s typically taken as needed, but lower doses can be taken daily for continuous ED management.
| 2.5mg – 5mg | Daily use for maintenance |
| 10mg – 20mg | As needed, prior to anticipated sexual activity |
Potential Side Effects
Common side effects include headache, flushing, nasal congestion, and muscle aches. These are usually mild and temporary. More serious side effects are rare, but prompt medical attention is necessary if they occur.
Important Considerations Before Use
Consult your doctor before using Cialis, especially if you have heart problems, high or low blood pressure, or take other medications. Cialis interacts with some drugs, including nitrates, which can be dangerous.
