Vidalista 80 mg, containing Tadalafil, is used to treat erectile dysfunction. Its effects can last up to 36 hours, which is why it's often called the "weekend pill." This extended duration allows for more spontaneity in sexual activity. However, the actual duration can vary based on individual factors such as metabolism, overall health, and other medications being taken. Typically, Vidalista 80 mg takes about 30 minutes to 1 hour to start working. It's important to follow dosage instructions provided by a healthcare professional to avoid potential side effects and ensure safe use.
