Have any of you taken Mucinex while pregnant?

Quote  |  Reply

I've been taking this for about two days due to a bad sinus infection I think. I started another thread about my month long headache too that I think is related to sinus. Mucinex is not on the list of approved medicines to take while pregnant but my primary doctor told me to take it along with Amoxicillin. I want to know if you all think it's ok to take Mucinex. I believe it's a category C along with Zyrtec. What are people with allergies and sinus problems supposed to take while pregnant? It seems that we cannot take anything. It SUCKS!!! Do we just have to suffer?

Have I harmed my baby by taking mucinex for about 2 days now. Should I stop? I'm so paranoid but I feel so bad physically. :(

What I can't figure out is why tylenol is safe but mucinex is not and they both have the same ingredients(guaifenesin and phenylephrine). Mucinex has more but still the same thing. Also Sudafed has the same ingredients too. I'm so confused here!!!

I used Mucinex while ttc.  Guaifenesin is supposed to thin the cervical mucous, too and that is supposed to help with conception.  So, I'm 99% sure the guaifenesin is not a problem.  I had to buy the Mucinex that listed that as it's only active ingredient.  There are lots of varieties of Mucinex. 

According to: unter-medications-during-pregnancy_1486462.bc

Avoid cold remedies that contain alcohol. Also avoid the decongestants pseudoephedrine and phenylephrine, which can affect blood flow to the placenta.

According to the FDA, this is what a Category C is:

If animal reproduction studies have shown an adverse effect on the fetus, if there are no adequate and well-controlled studies in humans, andif the benefits from the use of the drug in pregnant women may be acceptable despite its potential risks, the labeling shall state: "Pregnancy Category C. (Name of drug) has been shown to be teratogenic (or to have an embryocidal effect or other adverse effect) in (name(s) of species) when given in doses (x) times the human dose. There are no adequate and well-controlled studies in pregnant women. (Name of drug) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus." The labeling shall contain a description of the animal studies. If there are no animal reproduction studies and no adequate and well-controlled studies in humans, the labeling shall state: "Pregnancy Category C. Animal reproduction studies have not been conducted with (name of drug). It is also not known whether (name of drug) can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. (Name of drug) should be given to a pregnant woman only if clearly needed." The labeling shall contain a description of any available data on the effect of the drug on the later growth, development, and functional maturation of the child.

Plain Tylenol (acetaminophen) is generally considered safe in pregnancy.  Those others you mentioned are separate drugs contained in the cold/sinus preparations and are not what is generally meant when you hear about "Tylenol," which is safe.   Now, I have not looked them up to see what Category they are in, but just sayin'.  If they're in Category A, then great, my bad, and they're probably fine, on advice of your doc.

I also had the same problems, terrible sinus/allergies/asthma, on several meds for these when I became pregnant.  I stopped them all cold turkey out of high level of fear of harm to my baby and just the not knowing and preferring to err on the side of caution.  However, after I was 12 weeks along, I asked my doc if I could add back Allegra, as that was the one that helped me the most at the time, and he said yes.  He also said, "If you really need the medicine, take the medicine. "  He also prescribed me a narcotic cough medicine at one point (yes, my OB/GYN), to which I was like, "WTF?"  I filled the Rx but did NOT take it while pregnant.  I just didn't feel comfortable enough, regardless.  It came in handy several months later when I had a bad cough/cold that kept me from sleeping.  :-) 

Bottom line, ask your doctor.  Hopefully, you trust him/her.  In the end, though, it has to be your decision and what you are comfortable with, once you have weighed the positives/negatives.

Is it possible (and this is REALLY reaching) that you are in caffeine withdrawal, that you maybe used to consume caffeine and abruptly stopped due to being preg.?  I don't know that it would last this long, just thinking out loud, trying to help.

(sorry, I was kinda responding to your other post about "headache for a month" here, too, so I'm afraid it doesn't really answer this question, too much). 

Have you also changed your nutitional intake: like more zinc, vitamin C, Vit D, and added onion or garlic to your foods. You sound like you need to support your immune system (most drugs just suppress symptoms) so that you can help your body fight off the sinus infection.

Your body can heal itself when you give it the food (nutrients) it needs.

Hope you are feeling better soon.

I'm having the same problem.  I have a cold and I'm 32 weeks pregnant.  I just saw my OB today, and he told me he only wants me to take Sudafed and Robitusin.  I asked about Sudafed PE since that's what we actually have at home, and he said he'd prefer I do not take that and just use regular Sudafed.  I meant to ask his opinion of Mucinex, but it completely slipped my mind.  Prior to my doctor coming into the room, his nurse told me any Tylenol cold/allergy/sinus product was safe, but since my doctor didn't recommend them, I won't take any of those.  I googled it a few nights ago, and some websites said the various Tylenol cold products were safe to take, while other websites said not to take them.  Sorry I'm not answering your question about Mucinex, but I thought I'd share what my doctor told me was safe to take.  I hope you're feeling better soon! 

I agree with Vickiko.  It sounds like you need some immune support. When I pregnant I used lots of homeopathic supplements for immune support.  Zinc, Vit C, Echinacesia, ect.  

IF you have sinus problems you can also use essential oils like Eucalyptus and Tea Tree Oil to open your sinuses. One of my friends swears by using a Netti Pot.




My doctor told me the same thing that cecily's doctor told her. Regular Sudafed and Robitussen. When I was pregnant with my first, I took Tylenol Cold along with a Z-Pack because I had a horrible sinus infection at 39 weeks. My doctor didn't want me delivering while sick.

During my most recent pregnancy, I got a horrible cold at 38 weeks. I think I read somewhere that your immune system is the most suppressed during your third trimester so that's probably why pregnant women get sick toward the end of pregnancy. I agree with the other posters about boosting your immune system.

In The Vaccine Book by Dr. Robert Sears, some recommendations to boost a child's immune system are: taking Omega-3 (fish oil) supplements, vitamin A supplements (improves the immune response to infections) and (of course) vitamin C. One other thing I read in this book is being on antibiotics destroys probiotics (good bacteria) found in your intestines. Yogurt is high in acidophilus (aka probiotics) and it also comes in a liquid or powder form. Replacing these probiotics has been shown to increase immune response. If these remedies are safe for children, they are MOST LIKELY safe for pregnant women HOWEVER, you should always check with your doctor before taking supplements.

Get well soon!

I am 38 weeks pregnant and also have a sinus infection. I asked my Dr. about taking Mucinex and she said I could take regular Mucinex, but NOT Mucinex DM. Hope that helps you out. Good luck and feel better soon. Smile
