Fildena, when used as directed and under medical supervision, is generally safe for treating erectile dysfunction (ED). However, as with other medications, it may cause negative effects. Headaches, face flushing, dyspepsia, nasal congestion, and dizziness are all common adverse effects. These side effects are frequently moderate and transient. In rare cases, more severe side effects like priapism (prolonged, painful erections), sudden vision or hearing loss, and allergic reactions can occur. It’s crucial to consult a healthcare provider before using Fildena, discuss potential risks, and follow their guidance to minimise side effects and ensure safe usage.
