The antihypertensive drugs are divided into categories, some antihypertensive drugs can be eaten to have children, antihypertensive drugs can not be eaten to have children. If you have high blood pressure and have been taking oral medication to lower your blood pressure, you should understand the effects and side effects and contraindications of antihypertensive medications, such as methyldopa and nifedipine tablets, before you have children. If your blood pressure is well controlled during the medication period, gradually reduce the dosage and stop the medication, then consider having children, which is better for you and for your children. If your blood pressure is not well controlled and fluctuates, it is not advisable to have a child, because after pregnancy the blood viscosity will become higher and the blood volume will increase, which will cause an increase in blood pressure, which will aggravate the original hypertension and make it easier to be dangerous, so it is not worth the loss.
