 Pronounced: See-AL-issGeneric name: Tadalafil Why is this drug prescribed? Cialis is an oral drug for male impotence, also known as erectile dysfunction (ED). It works by dilating blood vessels in the penis, allowing hte in-flow of blood needed for an erection. Most important fact about this drug Cialis causes erections only during sexual excitment. It does not work in the absence of arousal and does not increase sexual desire. How should you take this medication? Take one Cialis tablet before sexual activity, with or without food. The best time to take Cialis depends on how and when the drug works for you, but some men are able to have an erection 30 minutes after taking it. Others are able to wait up to 36 hours after taking Cialis before engaging in sexual activity.
Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe to continue using Cialis.
