What is Zyrtec?

Zyrtec is a type of medication with an active ingredient called cetirizine. It’s an antihistamine that is used to treat allergy symptoms, head colds, and allergic reactions such as hives in people who experience them. You can buy it over-the-counter, and it can be taken daily during allergy season if you follow the directions on the label.

Zyrtec usually doesn’t contain any other types of medications other than its active ingredient, but you should still always double check the label to be sure when taking anything over-the-counter. Pure cetirizine medications are much different from those that include other substances.

Why is Zyrtec Safe?

Zyrtec is widely recommended as one of the safest allergy medication options for moms who are breastfeeding. But why is that? What makes Zyrtec so much safer than some other type of allergy medicine? It all comes down to the active ingredient: cetirizine. This is a medication that doesn’t have nearly the kinds of side effects that other allergy medicines might have. Below are just some of the reasons why Zyrtec is generally considered the safest option when it comes to taking allergy medications while breastfeeding.

  • Zyrtec has been around for a while and hasn’t shown any signs of problems. While this in itself isn’t necessarily the best reason to take a medication like this while nursing, it’s a good sign that you don’t have to worry about much when you do take it.
  • There have been several studies on the effects of Zyrtec on breastfeeding moms and babies, and none of these have shown any signs of any unwanted outcomes. While studies on medications like pseudoephedrine have shown that babies may sometimes become drowsy and moms may notice a drop in their milk supply when taking the medicine, Zyrtec and its active ingredient have not shown any of these results.
  • While the medication in Zyrtec can and does pass into breast milk when you nurse your baby, it doesn’t have any effects on your child. However, if you’re worried about taking anything that can pass to your baby at all, you may still want to avoid it. There really isn’t any reason to stay away from it, however, because even though your baby is exposed to it, he or she isn’t going to show any negative reactions to the presence of Zyrtec in your milk.

As you can see, there are a lot of reasons why Zyrtec is a good choice. If you still choose not to take it, that’s okay too, but bear in mind that it’s a better option than many other allergy medications on the market.

What are Side Effects of Zyrtec that May Affect Mom?

While you don’t have to worry about anything harming your baby when you take Zyrtec while nursing, there’s still a chance that you yourself will need to deal with side effects that may make your nursing experience more difficult than it has to be. Bear in mind that many of these are side effects that could potentially affect anyone, regardless of breastfeeding status, but when nursing these problems may be more serious or harder for you to deal with.

Digestive issues: 

Many nursing moms have noticed that the potential stomach upset and other digestive issues associated with taking Zyrtec are very pronounced for them. This is a common problem with Zyrtec and it’s not a cause for alarm, but it may make you feel worse than you would have initially just fighting off the allergies themselves.


Zyrtec often causes dizziness. However, if you’re a nursing mom, you probably don’t want to have to deal with this potential problem because there’s always a chance you could fall—even while holding your baby. If the dizziness is very severe, it could negatively impact your ability to take care of your baby during the time you’ll be taking the medication.


Like most allergy medications, Zyrtec will probably make you drowsy or groggy. You may even feel confused and unable to get up to take care of things when you need to. Once again, this is bound to be a problem while you’re taking care of a baby, and you should be cautious about taking any medication that will leave you unable to get up and tend to your child if you’re the only one home to do so. If your partner or another adult is available to help, however, this may be less of a concern.

Take note that Zyrtec doesn’t affect your milk production or your physical ability to nurse your child in any way. There have been no studies to prove that Zyrtec has any effect on milk production or nursing ability whatsoever, and moms generally don’t report noticing any kinds of issues related to this. Remember, however, that it can pass through your milk to your baby, but that your baby shouldn’t show any adverse reactions to being exposed to Zyrtec while you’re nursing him or her.


As you can see, there’s no reason not to take Zyrtec while you’re nursing your baby, if you need to. As with any type of allergy medication, however, it’s best to only take it when you need it and to cut back on it as soon as you start to feel better. These are usually pretty strong over-the-counter medications and could have more adverse effects on your own body if you continue to take them over a longer period of time.

With any medication, it’s important to follow the directions on the box in terms of dosage amounts and frequency. Never take more than the recommended amount of Zyrtec in a day or you may risk causing some harm to yourself or your child.

Remember to speak with your own healthcare provider or your child’s pediatrician if you have any further concerns about taking Zyrtec while nursing your baby. You may also be able to ask your pharmacist about anything you may want to be on the lookout for while doing this. You shouldn’t notice any problems, but it’s always important to be attentive to your baby and any changes he or she may be showing shortly after you start taking a new medication.
