Vilitra 10 mg, which contains vardenafil, is used to treat erectile dysfunction by increasing blood flow to the penis. While generally safe when taken as prescribed, long-term use may have side effects. Potential long-term effects include headaches, dizziness, nasal congestion, and digestive problems. Some users may experience changes in vision or sensitivity to light. Rarely, prolonged use may lead to dependency on the medication for sexual performance. Cardiovascular side effects like palpitations or blood pressure fluctuations are possible, especially in those with underlying heart conditions. Regular use without medical supervision may also mask deeper health issues. It's important to consult a doctor regularly when using Vilitra long-term.
