Tadalafil is a phosphodiesterase-5 (PDE5) inhibitor. It works by relaxing blood vessels in the penis, allowing increased blood flow for an erection. This mechanism is key to its effectiveness in treating erectile dysfunction (ED).
How Tadalafil Differs from Other PDE5 Inhibitors
Compared to sildenafil (Viagra), tadalafil boasts a significantly longer half-life, meaning its effects last considerably longer – up to 36 hours, earning it the nickname “the weekend pill.” This extended duration offers more flexibility in timing intimacy.
Unlike vardenafil (Levitra), tadalafil’s effects are less influenced by food intake. This makes it a convenient option for many men.
Dosage and Considerations
The typical starting dose of tadalafil for ED is 10mg. Your doctor will adjust this based on individual needs and response, potentially ranging from 2.5mg to 20mg. Always follow your doctor’s instructions. Tadalafil may interact with certain medications, particularly nitrates, so open communication with your doctor about your health history is paramount. Side effects, while generally mild, can include headache, flushing, and nasal congestion. Seek medical advice if you experience severe or persistent side effects.
