About:

Cialis is an oral drug for male impotence, also known as erectile dysfunction (ED). It works by dilating blood vessels in the penis, allowing the inflow of blood needed for an erection.

Cialis causes erections only during sexual excitement. It does not work in the absence of arousal and does not increase sexual desire.

How Taken:

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.

Missed Dose:

Take Cialis only before sexual activity, but no more than once a day. Do not take two doses at once.

Overdose:

Large doses of Cialis (up to 500 milligrams) resulted in similar side effects as regular doses. However, any medication taken in excess can have serious consequences. If you suspect an overdose, seek medical attention immediately.

Storage:

Store at room temperature.

Side Effects:

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.

More common side effects may include: arm and leg pain, back pain, flushing, headache, indigestion, muscle aches, nasal congestion
