While
Vilitra is generally well tolerated, some side effects may require attention. Common side effects include headache, flushing, nasal congestion, dizziness, and indigestion, which are usually mild and temporary. However, certain symptoms should raise concern and prompt medical advice. These include chest pain, irregular heartbeat, shortness of breath, or severe dizziness, which could indicate cardiovascular complications. Blurred vision, sudden hearing loss, or ringing in the ears are also warning signs that require immediate evaluation. If an erection lasts longer than four hours (a condition called priapism), it is a medical emergency. Additionally, allergic reactions such as rash, swelling, or difficulty breathing should be treated urgently.
