Antihistamine Breastfeeding And Pregnancy Issues

If you are concerned about antihistamine breastfeeding and pregnancy issues, there is good cause. Women should be very careful what they ingest, while pregnant, and when their babies are receiving breast milk. When it comes to medications, some types of antihistamines are considered safe, while others may be not. Here is a look at these medications, and why pregnant women need to exercise caution.

Antihistamines and Pregnancy

People take antihistamines for many different reasons, and they are not just for allergies. These medications are often taken for nausea and vomiting, and sometimes as a means of sedation. It is important to know that there are two major classes of antihistamines to consider. These classes are divided into first and second generations. The first generation medications are considered to be relatively safe during pregnancy. Second generation medications are designed to cause less drowsiness and sedation, and may or may not be safe.

First Generation and Pregnancy

First generation antihistamines have been around for some time, and many are considered to be safe for pregnant women. Some of these drugs are diphenhydramine, chlorpheniramine, brompheniramine, and hydroxyzine. However, it is very important to discuss any kind of drug with your doctor first.

When a woman is pregnant, she can be more susceptible to health conditions, and should only take medications, after talking to a doctor. For example, whether you are in the first, second, or third trimester, will make a difference on how medications affect the baby. This includes something as simple as aspirin or antacids. Everything that you ingest while pregnant, can have some effect on the growing life within you, so if you can do without medications, it is best to try.

Even though studies show that first generation antihistamines are safe for pregnant women, everyone is different. Also, medications should always be used with caution and moderation. You should only take drugs, when absolutely necessary.

First Generation and Breastfeeding

As a general rule, medications that are safe for pregnancy are also safe for breastfeeding. There does not appear to be a large percentage of the drugs secreted in breast milk. Yet, it is still important to talk to a medical professional for advice.

Second Generation and Pregnancy

Second generation antihistamines are often preferred by people, as they do not affect the central nervous system with drowsiness. Many people can work and drive without a lot if concern, when taking these drugs. These kinds of drugs include Loratadine, Fexofenadine, and Cetirizine.

Studies are very encouraging for the use of second generation drugs during pregnancy, but they are still relatively new. There is not enough research and studies to provide reliable information. Without these drugs, pregnant women are encouraged to treat allergies in other ways. Eliminating sources of mold and dust mites is important, as is sleeping with the head elevated to allow for easier breathing.

Second Generation and Breastfeeding

If you are nursing your baby, second generation antihistamines may be fine to use. Studies conducted on several popular drugs show that there is not any significant amount of the drugs secreted into breast milk. All the studies conclude that nursing and taking second generation antihistamines are relatively safe for the child. However, it must be emphasized that medical advice is vital before taking drugs, while nursing.

Another important thing to consider while pregnant is the possible side effects of medication. For example, if you are already suffering with dizziness or headaches while pregnant, some antihistamine medications can make the problem worse. Another important thing to consider is nausea. Nausea is very common in pregnancy, and if a medication makes the problem worse, it may be best to avoid it, and ask your doctor about a suitable replacement.

Make sure that you discuss your pregnancy matters with all doctors that you are seeing. For example, if you are seeing a family doctor and a baby doctor, be sure that they both are aware of any medications, prescribed or not, that you are taking. Some medications can have serious repercussions if taken at the same time as antihistamines.


If you are having problems with allergies or asthma, while pregnant or nursing, you may need to take an antihistamine medication. There are two basic kinds of antihistamines, known as first and second generation drugs. First generation medications have a long history and appear to be safe. Second generation medications are relatively safe, but not enough is currently known about them. Talk to your doctor or medical professional if you have antihistamine breastfeeding and pregnancy concerns. They can give you the best advice.
