Medications During Pregnancy

Most patients need medication sometime during their pregnancy. There are many common symptoms that should be treated and some that can be treated depending on the severity. Also many common medical conditions require treatment during pregnancy to protect the mother or fetus. These include asthma, thyroid disease, diabetes, seizure disorder, hypertension and others. Any chronic medication should be discussed to determine the optimal use during pregnancy including possible change or discontinuation of the medication. Many common conditions can be treated with over the counter medication and some of these are listed below. If any questions are present regarding medication these should be directed to our nurses and Dr. Duncan.

Medical Conditions in Pregnancy

Asthma –

“Pregnant asthmatic women should continue to use their asthma medication in the lowest dose possible to manage symptoms during pregnancy, according to a Practice Bulletin by The American College of Obstetricians and Gynecologists (ACOG). Women with moderate or severe asthma should also be monitored throughout pregnancy for fetal growth restriction and signs of preterm birth.”

The recommendations—based on a review of existing studies on asthma and pregnancy—support the findings of the National Asthma Education Prevention Program that state that “it is safer for pregnant women with asthma to be treated with asthma medications than it is for them to have asthma symptoms and exacerbations.” – ACOG

Diabetes –

Patients taking Insulin for type I diabetes will likely need to continue and possibly increase their medication during pregnancy. Gestational diabetes may require Insulin therapy but may also be able to be treated by dietary management.

Hypertension –

Chronic high blood pressure is a common condition. Medication to decrease blood pressure may be required both for fetal as well as maternal well being. All antihypertensive medication, however, is not safe during pregnancy. It is important to be on the appropriate medication if possible before pregnancy begins. Gestational hypertension may also occur alone or in combination with chronic hypertension. Medication and early delivery may be required.

Thyroid Disease –

Thyroid disorder is important to identify and treat in pregnancy. The effects on pregnancy can include low birth weight, preterm delivery, neurologic abnormalities and possible fetal loss. The incidence of hypothyroidism is from 3-8% of the population. It is important to continue thyroid medication when pregnant.
