While Fildena 100mg is generally well-tolerated, it is not without potential side effects. Common side effects may include headache, dizziness, flushing, nasal congestion, indigestion, or changes in vision. These side effects are typically mild and temporary. However, in rare cases, serious side effects such as priapism (prolonged erection) or sudden vision or hearing loss may occur. If any unusual or severe side effects are experienced, medical attention should be sought immediately.
