If you get menstrual period in the middle of taking Tegretol, it is recommended to stop taking the drug and start taking it orally from the fifth day of menstruation, and increase the dosage of Tegretol appropriately, so that bleeding will not occur in the middle of taking the drug. It is also important to take care not to miss any dose of Tegretol, because if you miss any dose, you may experience menstrual bleeding in the middle of taking the medication. If the dose is increased during the next menstrual cycle, it is recommended to do a detailed examination to understand the thickness of the endometrium and the endocrine situation.
