Vardenafil, like other phosphodiesterase-5 (PDE5) inhibitors, can cause side effects. Commonly reported reactions include headache, flushing, nasal congestion, and dyspepsia. These are usually mild and transient.
More serious, though less frequent, side effects warrant immediate medical attention. These include sudden vision loss, hearing loss, prolonged erection (priapism), and heart problems like chest pain or irregular heartbeat. Seek immediate medical help if you experience any of these.
Less Common Side Effects
Other reported side effects include dizziness, back pain, muscle aches, and changes in vision (such as blurred vision or sensitivity to light). These side effects are usually temporary. If they persist or worsen, consult your doctor.
Interactions and Precautions
Vardenafil interacts with certain medications, notably nitrates. Combining them can cause a dangerous drop in blood pressure. Inform your doctor about all medications you are currently taking, including over-the-counter drugs and herbal supplements, before starting Vardenafil. Pre-existing conditions such as heart disease, stroke, or low blood pressure require careful consideration before taking Vardenafil.
