Tadalafil works by increasing blood flow to the penis, facilitating an erection. This happens through the inhibition of a specific enzyme, PDE5. This enzyme normally breaks down cGMP, a molecule crucial for achieving and maintaining an erection. By blocking PDE5, tadalafil allows cGMP levels to remain higher, resulting in improved blood flow and erectile function.
Dosage and Administration
Tadalafil is available in various dosages, typically ranging from 2.5mg to 20mg. Your doctor will determine the appropriate dosage based on your individual needs and health status. It’s crucial to follow your doctor’s instructions precisely regarding dosage and frequency of use. Tadalafil is usually taken as needed, approximately 30 minutes before anticipated sexual activity. It’s important to note that tadalafil’s effects can last for up to 36 hours, significantly longer than other ED medications.
Potential Side Effects
Like any medication, tadalafil can cause side effects. Common side effects include headache, flushing, nasal congestion, and indigestion. These side effects are usually mild and temporary. Serious side effects are rare but can include vision changes or hearing loss. Seek immediate medical attention if you experience any serious side effects. Always discuss potential side effects with your doctor before starting treatment.
