Warning

Concomitant administration of nitrates is contraindicated. Strongly influences the

cytochrome P450 system. On prescription of new medicines this should be taken

into account.

Revatio®

Round, white film-coated tablets with 20 mg sildenafil. Sildenafil inhibits

phosphodiesterase type 5 (PDE5). Because it relaxes and widens the vessels it improves

exercise tolerance, cardiac output and quality of life. Often several medications

for pulmonary hypertension are prescribed concomitantly. In case of problems, refer to

the product description of all medications to see if they result from medication interaction,

side effects or medication effects. Immediately contact the patient's pulmonologist in case

of problems.

Side effects

Fatigue, dizziness, headache, gastro-intestinal complaints and muscle pain. Rarely visual

disturbances or cloudy view occur.
