Telmisartan (the active ingredient in your medication) does not directly interfere with egg fertilization or implantation. However, this class of blood pressure medication is not safe to take during pregnancy as it can pose risks to a developing baby. If you are planning to conceive, it is highly recommended to speak with your doctor. They can safely transition you to a pregnancy-safe alternative, such as labetalol or methyldopa, before you begin trying. Please do not stop taking your current medication abruptly; consult your healthcare provider first to plan a safe transition.
