Pregnancy of Toprol XL in details

Pregnancy is always a special situation where every action or side effect of the drug varies when compared to a situation of a non-pregnant patient. It is not only because the pregnant woman's metabolism differs due to the hormonal and other changes happened to her, but also because every medicine or its metabolite passes to the baby and shows its action there. The only thing is, be cautious, attentive and well supervised when you take any single drug in pregnancy. The interactions can vary in pregnancy, and the dosage may differ as well. Strict supervision of the Physician is mandatory.

Toprol XL and the metabolite alpha-hydroxymetoprolol cross the placenta (Lindeberg 1987; Ryu 2016).

Exposure to beta-blockers during pregnancy may increase the risk for adverse events in the neonate. If maternal use of a beta-blocker is needed, fetal growth should be monitored during pregnancy and the newborn should be monitored for 48 hours after delivery for bradycardia, hypoglycemia, and respiratory depression (ESC [Regitz-Zagrosek 2018]).

Chronic maternal hypertension is also associated with adverse events in the fetus/infant. Chronic maternal hypertension may increase the risk of birth defects, low birth weight, premature delivery, stillbirth, and neonatal death. Actual fetal/neonatal risks may be related to duration and severity of maternal hypertension. Untreated chronic hypertension may also increase the risks of adverse maternal outcomes, including gestational diabetes, preeclampsia, delivery complications, stroke, and myocardial infarction (ACOG 203 2019).

The pharmacokinetics of Toprol XL may be changed during pregnancy; the degree of changes may be dependent upon maternal CYP2D6 genotype (Ryu 2016).

When treatment of hypertension in pregnancy is indicated, beta-blockers may be used. Specific recommendations vary by guideline but use of Toprol XL may be considered (ACOG 203 2019; ESC [Regitz-Zagrosek 2018]; Magee 2014). Females with preexisting hypertension may continue their medication during pregnancy unless contraindications exist (ESC [Regitz-Zagrosek 2018]). Toprol XL may be used for the treatment of maternal ventricular arrhythmias, atrial fibrillation/atrial flutter, or supraventricular tachycardia during pregnancy; consult current guidelines for specific recommendations (ACC/AHA/HRS [Page 2016]; ESC [Regitz-Zagrosek 2018]). Use of Toprol XL may be considered if migraine prophylaxis is needed in a pregnant woman (Pringsheim 2012).

Toprol XL breastfeeding

When a drug is taken when the patient is breast feeding, a part of the drug is secreted in her breast milk and is passed to the baby. The dosage of the medicine to mother and baby are different, and many drugs actions are side effects when you take them without a disease, and what if you the baby takes them without a disease? What if the drug is contraindicated in newborns, infants or children? So, breastfeeding is a very alarming situation when the mother is on medications. Ask your Physician or Pediatrician about the effect of the drug on the baby and how much is excreted in breast milk and if it harms the baby!
