Super Fildena belongs to the class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing the blood vessels in the penis, increasing blood circulation during sexual stimulation. This enhanced blood flow helps produce an erection when combined with sexual arousal. Common side effects include headaches, flushing, nasal congestion, dizziness, upset stomach, and visual disturbances. Serious side effects are rare but can include prolonged erections or sudden changes in vision or hearing.
