Tadalafil is a phosphodiesterase-5 (PDE5) inhibitor. This means it works by relaxing blood vessels in the penis, allowing for increased blood flow necessary for an erection. This mechanism is similar to how other medications, like sildenafil (Viagra), function. The effects typically begin within 30 minutes and can last up to 36 hours, significantly longer than many other erectile dysfunction treatments. This extended duration is a key difference compared to other PDE5 inhibitors.
Dosage and Administration
Tadalafil comes in various strengths, typically ranging from 2.5mg to 20mg. Your doctor will determine the appropriate dosage based on your individual needs and health condition. It’s typically taken as needed, about 30 minutes before sexual activity. However, some men may benefit from a lower daily dose for ongoing treatment. Always follow your doctor’s instructions precisely. Do not exceed the recommended dose.
Important Considerations
Tadalafil interacts with certain medications, particularly nitrates used to treat chest pain. Combining them can cause a dangerous drop in blood pressure. Inform your doctor about all medications, supplements, and herbal remedies you are currently taking. Individuals with heart problems, liver or kidney disease should discuss using Tadalafil with their physician before starting treatment. Side effects, while generally mild, can include headache, flushing, nasal congestion, and indigestion. Severe side effects are rare, but seek immediate medical attention if you experience vision changes, chest pain, or prolonged erection.
