Does taking metoprolol cause other pregnancy complications? Metoprolol has been associated with reduced growth of the baby.
Can metoprolol be used in pregnancy?

Can beta blockers cause miscarriage?
Can taking propranolol in pregnancy cause miscarriage? A single study provided no evidence that use of propranolol in early pregnancy was linked to an increased risk of miscarriage. No further studies have assessed miscarriage rates in women taking propranolol and more research into this subject is therefore required.
Can you breastfeed while taking metoprolol?
Because of the low levels of metoprolol in breastmilk, amounts ingested by the infant are small and would not be expected to cause any adverse effects in breastfed infants. Studies on the use of metoprolol during breastfeeding have found no adverse reactions in breastfed infants. No special precautions are required.
What does pregnancy category D mean?
There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
Can beta-blockers cause birth defects?
Beta-blockers used to treat hypertension during the first trimester of pregnancy don’t appear to increase the risk that babies will be born with birth defects or cardiac malformations, according to an analysis of observational data on more than 18,000 women across five Nordic countries and the United States.
Why diuretics are contraindicated in pregnancy?

The two fatal overdose levels were deter- mined to be 50 mg/L in blood and 120 mg/kg in liver (6), and 56 mg/L in blood, 42 mg/L in vitreous humor, 276 mg/L in bile, and 260 mg/kg in liver (7). Several analytical procedures for the determination of metoprolol in biological specimens have been reported (8-13).
