Hello, I can understand your concern. Mercilone is a hormonal contraceptive pill. If the sex hormones are imbalanced and patient feels mood swings and other psychological symptoms due to that, this pill is used to control the hormonal balance and help control related symptoms. Though this molecule has potential for some adverse effects, severe anxiety is not one of them. There might be some other condition related to your this problem. I would advise you to visit your physician or mental health professional who can go into detailed history of your physical and mental health and can ascertain the possible cause of the anxiety episodes. Treatment can be started based on the cause. I hope this information helps you. Thank you for choosing HealcareMagic. Take care. Best, Dr. Viraj Shah
