Hi, Thanks for posting in HCM. I understand your concern. Iterax contains hydroxyzine, which is a first-generation antihistamine that is used to treat allergies and anxiety. It has sedative effects also. Kindly take the medication as advised by your doctor. It would take care of problems like vertigo as well as sleeplessness. You can practice meditation, which would help to keep your mind calm and healthy. Also drink good quantities of water and keep yourself well hydrated. These measures should help you to overcome the problems what you are facing. Hope the information provided would be helpful. All the best.
