Vidalista 20 contains tadalafil 20 mg, which is used to treat erectile dysfunction. Tadalafil is known for its longer duration of action compared to sildenafil, lasting up to 36 hours. Regarding long-term use of Vidalista 20, here’s what you should know: Potential long-term risks or concerns: Cardiovascular effects: Tadalafil can lower blood pressure. Long-term use in people with heart conditions needs careful monitoring. Risk of interactions with medications like nitrates (dangerous drop in blood pressure). Vision and hearing: Rarely, long-term use has been linked to vision changes or sudden hearing loss, though this is uncommon. Priapism: Vidalista 20 erections lasting more than 4 hours (priapism) are rare but serious. Repeated episodes can cause tissue damage. Other side effects: Headache, back pain, muscle aches, flushing, nasal congestion can persist or recur. Tolerance or psychological dependence: Some men might feel reliant on the medication for sexual performance, but this is more psychological. What studies say: Tadalafil has been studied for daily use (lower doses like 2.5 mg or 5 mg) for months and is generally considered safe with proper medical supervision. Using 20 mg daily is less common and may increase the chance of side effects. Long-term safety data is stronger for lower daily doses than for as-needed 20 mg daily use. Recommendations: Always use Vidalista 20 under medical supervision, especially for long-term use. Regular check-ups are important to monitor heart health and other potential side effects. If you experience vision changes, chest pain, or prolonged erection, seek immediate medical help.
