For the use of antihypertensive drugs for postpartum hypertension, if the patient wishes to breastfeed, she may breastfeed for a short period of time with close monitoring of blood pressure. For the use of drugs for postpartum hypertension, calcium antagonists, such as nifedipine, or beta-blockers, such as labetalol and metoprolol extended release, may be considered. Propranolol and atenolol are not recommended. Methyldopa and diuretics are not advocated because methyldopa can increase the incidence of postpartum depression and diuretics can cause hypovolemia in pregnant women, leading to electrolyte disturbances. Angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists are contraindicated in breastfeeding women. If postpartum women cannot confirm whether antihypertensive drugs are safe for their breasts, they should decisively stop breastfeeding or change medications.
