Vidalista 80 contains tadalafil, primarily used to treat erectile dysfunction. However, there are important contraindications to consider before taking it. Individuals who use nitrates for chest pain or heart problems should never take Vidalista 80 mg because the combination can cause a dangerous drop in blood pressure. It is also contraindicated for people with severe cardiovascular conditions, such as recent heart attack, stroke, or uncontrolled high or low blood pressure. Those with severe liver or kidney impairment should avoid it or use it cautiously under medical supervision. Additionally, people allergic to tadalafil or any component of Vidalista 80 should not take it. Consulting a healthcare professional before use is essential to ensure safety.
