Heart Medicines During Pregnancy: What Is Safe and What to Avoid
If you have a heart condition and are pregnant — or planning to become pregnant — one of the most important questions you may have is: "Is my medicine safe for my baby?"
Dr. Nikhila Pachani, Consultant Interventional Cardiologist at Backbone Medicity Hospital, Rajkot, has shared clear and helpful guidance on this topic.
Why This Matters
During pregnancy, whatever you take can reach your baby through the placenta. This means some medicines that are perfectly fine for you may affect your baby's growth or development. At the same time, stopping your heart medicine without a doctor's advice can also be dangerous — for both you and your baby.
The key is knowing which medicines are considered safer and which ones should be avoided.
Medicines That Can Be Used (Under Medical Supervision)
Some heart medicines have a reasonable safety record during pregnancy when used carefully:
- Beta-blockers like labetalol are commonly used to manage high blood pressure during pregnancy and are generally considered acceptable under close medical monitoring.
- Certain blood thinners may also be used when necessary, depending on your condition and stage of pregnancy. Your doctor will choose the right type and dose for you.
Medicines to Avoid During Pregnancy
Some heart medicines carry a known risk of causing harm or birth defects and should generally not be used during pregnancy:
- ACE inhibitors (e.g., enalapril, ramipril)
- ARBs — Angiotensin Receptor Blockers (e.g., losartan, telmisartan)
- Statins (used to lower cholesterol)
These medicines may affect the baby's kidney development and overall growth, especially in the second and third trimesters. If you are currently on any of these, do not stop them suddenly — speak to your cardiologist right away so a safer alternative can be planned.
The Most Important Step: Talk to Your Doctor
Every pregnancy is different. Every heart condition is different. What is safe for one person may not be right for another. Never start, stop, or change your heart medicine on your own during pregnancy.
Both your heart health and your baby's health depend on getting this right — and that is only possible with the right medical guidance.
If you are pregnant and taking heart medicines, or if you are planning a pregnancy and have a heart condition, consider booking a consultation with a qualified cardiologist to review your treatment plan.
