Little safety information has been collected around the use of this combination medication in pregnant women. However, studies have investigated the safety of hydrocodone and chlorpheniramine separately.

Human studies have not identified a direct association between hydrocodone or chlorpheniramine exposure in utero and an increased risk of birth defects. Chlorpheniramine is considered a preferred antihistamine for use during pregnancy. Antihistamine use during the last two weeks of pregnancy has been associated with an eye condition known as retrolental fibroplasia, which can cause blindness in newborns. Opioids such as hydrocodone can cause respiratory depression in newborns as well as dependence and withdrawal symptoms in newborns including irritability, fever, and vomiting. Use of hydrocodone during labor and delivery can slow labor. Hydrocodone/chlorpheniramine should only be administered during pregnancy if the benefits to the mother outweigh the risks to the developing baby.

General information

It is very common for women to worry about having a miscarriage or giving birth to a child with a birth defect while they are pregnant. Many decisions that women make about their health during pregnancy are made with these concerns in mind.

For many women these concerns are very real. As many as 1 in 5 pregnancies end in a miscarriage, and 1 in 33 babies are born with a birth defect. These rates are considered the background population risk, which means they do not take into consideration anything about the health of the mom, the medications she is taking, or the family history of the mom or the baby’s dad. A number of different things can increase these risks, including taking certain medications during pregnancy.

It is known that most medications, including over-the-counter medications, taken during pregnancy do get passed on to the baby. Fortunately, most medicines are not harmful to the baby and can be safely taken during pregnancy. But there are some that are known to be harmful to a baby’s normal development and growth, especially when they are taken during certain times of the pregnancy. Because of this, it is important to talk with your doctor or midwife about any medications you are taking, ideally before you even try to get pregnant.

If a doctor other than the one caring for your pregnancy recommends that you start a new medicine while you are pregnant, it is important that you let them know you are pregnant.

If you do need to take a new medication while pregnant, it is important to discuss the possible risks the medicine may pose on your pregnancy with your doctor or midwife. They can help you understand the benefits and the risks of taking the medicine.

Ultimately, the decision to start, stop, or change medications during pregnancy is up to you to make, along with input from your doctor or midwife. If you do take medications during pregnancy, be sure to keep track of all the medications you are taking.
