Recognizing serious side effects of Zhewitra 20 mg, which contains Vardenafil, is crucial for ensuring safe use. While mild symptoms like headache, flushing, or nasal congestion are common, certain side effects require immediate medical attention. One of the most alarming is priapism—an erection lasting more than 4 hours—which can cause permanent damage to penile tissue if not treated promptly. Vision disturbances, such as sudden vision loss in one or both eyes, or seeing a blue tinge around objects, could indicate non-arteritic anterior ischemic optic neuropathy (NAION), a rare but serious condition.

Similarly, sudden hearing loss, often accompanied by ringing or dizziness, should not be ignored. Other serious signs include chest pain, irregular heartbeat, fainting, shortness of breath, or swelling in the hands, ankles, or feet, which may indicate cardiovascular issues. Patients with heart, liver, or kidney conditions should be extra cautious. Promptly consult a doctor if any of these symptoms occur. Ask ChatGPT
