Certain individuals should avoid using Fildena Super Active altogether or use it with caution due to heightened risks of adverse effects. This includes men with pre-existing cardiovascular conditions such as heart disease, hypertension, or those who have recently experienced a heart attack or stroke. Individuals taking nitrates for chest pain (angina) or alpha-blockers for prostate conditions should also steer clear of Fildena Super Active due to potentially dangerous interactions that could cause severe drops in blood pressure.
