Vidalista 80 mg, which contains tadalafil, is a medication primarily used to treat erectile dysfunction in men. It is not typically associated with causing changes in menstrual cycles because it does not directly affect hormonal levels or functions related to the menstrual cycle in women.

Tadalafil, the active ingredient in Vidalista 80 mg, works by increasing blood flow to the penis, which helps men achieve and maintain an erection during sexual stimulation. It does not have a direct impact on the reproductive system or hormonal balance in women.

If a woman experiences changes in her menstrual cycle or any other reproductive health concerns, they are unlikely to be directly caused by Vidalista 80 mg. However, if there are any concerns about menstrual irregularities or other health issues, it's important to consult with a healthcare provider for a thorough evaluation and appropriate management. They can help determine the underlying cause and provide guidance on any necessary treatment or adjustments.
