Hello,
With the question “How to use medicine to treat high blood pressure while breastfeeding? , the doctor answered as follows:
Antihypertensive drugs that can be used during breastfeeding include:
Beta blockers: The drugs that are considered safe are propranolol, metoprolol, labetalol . Be careful not to use atenolol. Calcium channel blockers: The drug that is considered safe - nifedipine. For diltiazem and verapamil, there are no reported safety data for breastfeeding women. Other calcium channel blockers may be safe to use. ACE inhibitors: Drugs such as captopril, enalapril are considered quite safe for nursing mothers. Avoid taking other ACE inhibitors. Angiotensin II receptor antagonists and thiazide diuretics: There are no data on safety in nursing women. However, your doctor may consider giving it to you as needed or consider other alternatives. However, each drug has indications and contraindications, so you need to see a cardiologist for specific and safe drugs, avoiding side effects that cause both mother and child.
If you still have questions about the use of antihypertensive drugs while breastfeeding, you can go to a medical facility of Vinmec Health System for early examination and treatment. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
