[Side effects of sildenafil: findings from two years practical experience].
Sildenafil has been registered for the treatment of erectile dysfunction since 1998. World wide a large number of patients were reported, dying of acute heart disease after using sildenafil. Therefore the patient instruction text was adapted. Simultaneous use of sildenafil and nitrates is contraindicated because of serious decrease of the blood pressure. The use of sildenafil can lead to physical stress in patients with a history of heart disease and a treadmill test assessment is advisable. In two years 38 adverse reactions were seen in 25 Dutch patients. The Dutch reports (three cardiovascular deaths since the introduction) also show the dilemmas in the assessment of the safety of sildenafil: is it the underlying disease or is it the drug that causes death? Further research into the adverse reactions has to be done, therefore reporting suspected side effects of sildenafil is important.
