Tadalafil is a medication belonging to a class of drugs called phosphodiesterase-5 (PDE5) inhibitors. It works by increasing blood flow to the penis, which helps achieve and maintain an erection. This happens because Tadalafil blocks the action of PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a substance that relaxes the muscles in the penis.
How Tadalafil Affects the Body
Increased cGMP levels lead to vasodilation – widening of blood vessels. This allows more blood to flow into the penis, leading to an erection in response to sexual stimulation. It’s crucial to remember that Tadalafil does not cause erections spontaneously; sexual stimulation is still required.
Tadalafil Dosage and Administration
Tadalafil comes in different dosages, typically ranging from 2.5mg to 20mg, and is usually taken orally. The appropriate dosage depends on individual needs and medical history; consult your doctor for personalized guidance. The medication can be taken with or without food.
| 2.5-5 | Daily Use |
| 10-20 | As-needed Use |
Always follow your doctor’s instructions regarding dosage and frequency. Misuse can lead to adverse effects.
Potential Side Effects
Common side effects include headache, flushing, nasal congestion, and indigestion. Serious side effects are rare but can include vision changes, hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience any serious side effects.
