Tadalafil (generic Cialis) is a fast-acting prescription medication that will start to work within 30-60 minutes after ingestion. As a treatment for ED, tadalafil should be taken at least 30 minutes before sexual activity. It is important to note that tadalafil is not enough to cause an erection by itself. Tadalafil helps increase blood flow, which can improve erections that result from sexual stimulation.
Tadalafil is meant to be taken only once a day. Do not increase the dosage or stop taking tadalafil unless directed by your doctor.
