Can You Take Mucinex While Pregnant? Know It All!

When you’re pregnant, you’ll avoid getting sick by eating the right food and taking medications daily. You’ll then consider some over-the-counter drugs because they are more accessible. And the best one on the shelf is Mucinex. But the big question is: can you take Mucinex while pregnant?

Sad to say, during your journey of nine months, you can’t dodge getting sick. No matter how hard you avoid it, the flu will creep in and have you sniveling for some time. It’s been suggested that one should not take medicines during the first trimester unless necessary. So, how can we actually say that Mucinex is safe? Let’s discuss it below.


What Is Mucinex?


Mucinex is a medication taken by people caught by colds, allergies, and flu. It helps alleviate the feeling of chest and nasal congestion by thinning the mucus. It is also a cough suppressant because it relieves the lungs and chest from the phlegm.

This over-the-counter drug has three active ingredients that ease the person taking it. These are guaifenesin, pseudoephedrine, and dextromethorphan. We have to know them all, and whether can you take Mucinex while pregnant.​


The ingredient is an expectorant that thins out the mucus linings on the lungs, therefore, relieving the congestion of the chest. When that happens, it makes coughing easier and painless, providing you a much easier breathing. According to the group, American Family Physician, there has not been any study that says guaifenesin is safe to take during pregnancy. As such, it’s better not to drink the meds when you’re still on your first trimester.


Pseudoephedrine decongests the mucus in your nasal passages by thinning and shrinking the blood vessels. That way, it relieves that stubborn stuffiness in your nose. Take note: taking pseudoephedrine medicines during the first trimester may cause congenital disabilities. Avoid Mucinex if you’re still on that stage of your pregnancy.


It subdues the cough by signaling the brain to suppress the cough reflex. Though this ingredient is safe for pregnant women to take, it’s the only one that makes up Mucinex for what it is.

Overall, don’t take over-the-counter drugs without the supervision of your doctor. Moreover, your first trimester is the most crucial stage for your unborn child. The fetus is just growing and has not fully developed his or her organs and immune system. Taking Mucinex during the first trimester of your pregnancy can harm the baby.

Mucinex Category And Risks During First Trimester

The Food and Drug Administration has classified the drug as Class C, and animal studies show that Mucinex can intersect the placenta and have harmful effects on the growing fetus. Whether or not can you take Mucinex while pregnant, you have to be aware of these issues.

  • According to PregMed, a study was made by the Collaborative Prenatal Project and showed that there were 14 congenital disabilities, all congenital malformations when mothers took guaifenesin during the first trimester. About 197 pregnant women took part of the study.
  • Another study reported by the group was that there were 229,101 pregnant volunteers and 141 of them took guaifenesin in their first trimester. The result showed nine congenital disabilities and reported cases of cardiovascular issues in babies.
  • There’s also the possibility of babies having neural tube effects.

How To Take Mucinex During Pregnancy


First of all, talk to your doctor about the drug and see if he or she can see to it or prescribed something safer. Use the medicine as prescribed on the label to avoid any overdose of the drug. Flu medicines are taken until you’re well enough without them.

Recommended dosage

For adults, drink 200 to 400 milligrams of the said medication every 4 hours. Oral intake is advised and must not exceed 2.4 grams a day.​

Some advice​
