how long does it take for cialis to work

Cialis typically starts working within about 30 minutes after taking it, but it can take up to 1 to 2 hours to reach its peak effect. The effects can last for up to 36 hours, allowing for a long window of opportunity for sexual activity. However, sexual stimulation is still required for Cialis to work effectively. The timing can slightly vary depending on individual factors such as age, kidney or liver function, and dosage form (daily or as-needed).
