Is Propranolol Safe in Pregnancy? What to Ask
Published 2026-07-12 | By SafeMama Editorial Team | Editorial policy
Short answer
Propranolol can be used in pregnancy when your clinician decides it is the right choice. Do not start or stop it on your own. The reason you take it, dose, trimester, growth scan plan, and newborn monitoring all matter.
Individualized prescriber decision
What is the safest way to think about this?
NHS guidance says propranolol can be taken during pregnancy and notes that extra growth scans may be offered later in pregnancy. MotherToBaby says studies on beta-blockers have not reported an increased chance of birth defects overall, while propranolol has been linked with low birth weight and late pregnancy exposure can mean newborn checks for slowed heart rate, low blood pressure, or low blood sugar. BUMPS notes that propranolol may be used for several conditions, so the risk-benefit discussion depends on why it was prescribed.

What is generally okay?
- Review why you take propranolol with your prescriber and obstetric clinician, especially if it is for anxiety, migraine prevention, heart rhythm, blood pressure, tremor, or thyroid symptoms.
- Ask whether propranolol is still the preferred beta-blocker for your diagnosis or whether another medicine fits pregnancy better.
- Ask whether extra fetal growth scans are needed later in pregnancy if treatment continues.
- Ask whether your baby will need heart rate, blood pressure, or blood sugar checks after birth.
- Tell your clinician about asthma, diabetes, low blood pressure, fainting, heart rhythm symptoms, migraine medicines, anxiety treatment, or other heart medicines.
What should you avoid or double-check?
- Avoid stopping propranolol suddenly without guidance.
- Avoid starting propranolol for anxiety symptoms during pregnancy unless a clinician prescribed it for you.
- Avoid combining it with other medicines that lower heart rate or blood pressure without review.

Frequently asked questions
Is propranolol safe in pregnancy?
It can be used when your clinician decides the benefits outweigh the risks. Ask whether propranolol is still the right choice for your diagnosis, dose, trimester, and monitoring plan.
Can you take propranolol while pregnant?
Yes, if your clinician recommends continuing it. Do not start, stop, or change the dose on your own. If it was prescribed for migraine, heart rhythm, tremor, blood pressure, thyroid symptoms, or anxiety symptoms, ask how pregnancy changes the plan.
What if I already took propranolol before knowing I was pregnant?
Do not stop suddenly or panic. Contact your prescriber with the dose, product name, and dates so they can decide whether you should continue, adjust, or switch treatment.
Is propranolol used for anxiety in pregnancy?
BUMPS says propranolol is used for anxiety in some people. Anxiety care in pregnancy should still be individualized, and therapy or a different medicine may be considered for some patients.
Will propranolol mean extra growth scans?
NHS says propranolol can sometimes affect a baby's growth, so extra growth scans later in pregnancy may be offered. Ask your obstetric team what applies to you.
Can beta-blockers affect newborns?
Late pregnancy beta-blocker exposure can mean newborn monitoring for heart rate, blood pressure, or blood sugar. Tell the delivery team if you take propranolol.
Can you breastfeed while taking propranolol?
NHS says it is OK for many healthy babies when a doctor or pharmacist agrees. Ask for advice if your baby is premature, unwell, sleepy, feeding poorly, or not gaining weight as expected.
Is propranolol different from labetalol or metoprolol?
Yes. They are all beta-blockers, but pregnancy use, dose, and monitoring can differ by medicine and condition.
