how long does it take for tadalafil to work

Tadalafil typically starts working about 30 minutes after taking it, but it can take up to two hours for the full effect to be felt. The drug helps by increasing blood flow to the penis, but sexual arousal is still necessary for it to work. The effects of tadalafil can last up to 36 hours , which is why it is sometimes called the "weekend pill." For daily dosing of lower amounts, the drug builds steady levels in the body, allowing for more spontaneous sexual activity without timing the dose precisely.
