Vilitra contains vardenafil, a PDE5 inhibitor used to treat erectile dysfunction (ED) in men. Like other ED medications, it can have some side effects. It’s important to be aware of situations where you should seek medical help after taking Vilitra. You should seek immediate medical help if you experience: Prolonged or Painful Erection (Priapism): If you experience an erection that lasts more than 4 hours or is painful, seek emergency medical attention immediately. This is a serious condition called priapism that can cause permanent damage to the ***** if not treated promptly. Severe Chest Pain: If you feel severe chest pain, discomfort, or tightness during or after taking Vilitra, especially if it’s accompanied by sweating, nausea, or pain radiating to your jaw or left arm, seek emergency medical attention right away. This could be a sign of a heart attack. Sudden Loss of Vision: If you experience sudden vision changes, such as loss of vision or difficulty distinguishing colors (e.g., a blue or green tint), stop using the medication and contact a healthcare professional immediately. This could indicate a serious side effect affecting your eyesight. Sudden Loss of Hearing: If you notice a sudden decrease in hearing or ringing in the ears, seek medical help. This is a rare but serious side effect associated with vardenafil and other PDE5 inhibitors. Severe Dizziness or Fainting: If you experience severe dizziness, lightheadedness, or fainting, it could be due to a drop in blood pressure. This should be addressed immediately, as it could lead to further complications. Breathing Problems: If you have trouble breathing, wheezing, or feel short of breath after taking Vilitra, seek medical help promptly.
