About This Program
How quickly does tadalafil work?
Tadalafil begins working within ~30 minutes for most users and can last up to 36 hours, which is why it is sometimes called "the weekend pill."
Do I need lab work for tadalafil?
No. A provider review of your health history is required, but routine lab work is not part of starting tadalafil.
How is tadalafil 20 mg dosed?
Tadalafil 20 mg is taken as needed before sexual activity — typically 30 minutes beforehand. Its long duration (up to 36 hours) means you don't need to time it precisely. Do not take more than one dose in 24 hours.
