CIALIS - a patient's guide
Editorial Team

DRUG NAME: Tadalafil

USE: Erectile dysfunction (impotence)

This medicine is prescribed when a male cannot get, or keep, a hard erect penis suitable for sexual activity. Cialis is a phosphodiesterase type-5 inhibitor -- it works by relaxing the blood vessels and allowing blood to flow into the penis when sexually excited, thus allowing you to obtain an erection in a natural way.

Cialis will only work if you are sexually excited.

Cautions:

Cialis should not be taken by patients on nitrate containing drugs - these are medications used in the treatment of angina.

Contra-indications: hypotension, recent stroke, unstable angina, and myocardial infarction. Cialis should also not be taken by patients with moderate heart failure, uncontrolled arrhythmias, or uncontrolled hypertension.

Other conditions to beware of when taking Cialis:

- Heart conditions (chest pain)
- High blood pressure
- Diabetes
- Kidney or liver problems
- Anatomical deformation of the penis
- Blood disorders (haemophilia)

Most patients who are generally healthy and active can safely take Cialis - it is important to discuss with your doctor prior to taking it.

Side effects:

Occasional:

- headache, dizziness
- flushing
- blurred vision
- indigestion
