Is Mucinex Safe During Pregnancy?
It is important to understand the safety of individual active ingredients of Mucinex to ascertain its safety in pregnancy (4).
It is an expectorant drug that works by thinning the mucus in the airways to relieve chest congestion. It makes coughing up the phlegm (mucus) easier. You should seek medical advice before using the drug if you have conditions such as asthma, emphysema, or chronic bronchitis (5).
Since it is unknown if the medication crosses the placenta, its safety has not been fully established. According to some studies, there is a slender link between maternal Guaifenesin use and newborn inguinal hernias and neural tube defects (birth defects of the brain or spinal cord). The FDA classifies the medication as being in pregnancy category C, which indicates that either no studies have been conducted on animals, or there have not been any studies on both animals and humans.
If the advantages outweigh the risks to the fetus, the drug may be preferred after consulting a doctor. Guaifenesin should ideally be avoided in the first trimester. Quick tipWhile taking guaifenesin, it is advised to continue eating normally and drinking plenty of fluids. Seek your doctor’s advice on this.
The antitussive or cough suppressant medication works by reducing the activity of the part of the brain associated with coughing action (6). It is a pregnancy category C drug, but human studies have not shown any risk of major malformations during pregnancy.
It lessens blood vessel swelling in the nasal passages. It alleviates the symptoms of stuffy nose brought on by colds, allergies, hay fever, and sinus pressure (7). This pregnancy category C drug crosses the placenta. Some research suggests a link between phenylephrine use in the first trimester and endocardial cushion defect, a congenital heart malformation in which the walls dividing the four heart chambers are not properly formed. Only after consulting a doctor should you take the medication, and ideally you should avoid taking it during the first trimester.
It is a commonly used drug during pregnancy, with 65% of pregnant women using it at some point in pregnancy (4). Acetaminophen crosses the placenta but is not associated with any significant increase in the risk of fetal problems. Some studies associate prenatal and infant exposures to acetaminophen with mid-childhood executive function and behavioral problems, but it needs further research (9). The FDA categorizes the drug as pregnancy category B, which means that animal studies have not demonstrated any risks with no studies among women or animal studies have shown some risks, but it was not confirmed to occur in women.
Most Mucinex products contain ingredients whose safety has not been proven. So it’s best to stay away from Mucinex at least during the first trimester of pregnancy. If you wish to use the medication at any point while pregnant, you should ideally speak with your doctor first. Point to keep in mindDuring the first 12 weeks of pregnancy, your baby grows the fastest. Consequently, it is advised to stay as far away from medications and other harmful substances as possible. Folic acid consumption during this time reduces the risk of spinal birth defects (
How Much Mucinex Is Safe During Pregnancy?
Mucinex dosage varies according to its product variant. The manufacturer’s recommended maximum dosage is two tablets, capsules, or capsulets, or 20 ml of liquid every four hours during a 24-hour period. If you want to know what dosage is best for you while pregnant, speak with your healthcare provider.
The following table summarizes the maximum permissible dosage of individual drugs for pregnant women. You may use this table only for reference and not self-medication (10).
| Active Ingredient | Maximum dose in 24 hours |
|---|---|
| Guaifenesin | 2400mg |
| Dextromethorphan | 120mg |
| Phenylephrine | 240mg |
| Acetaminophen | 3000mg |
As Dr. Robyn Horsager-Boehrer wrote in a post for UT Southwestern Medical Center, avoid medication formulated for multiple symptoms during pregnancy, as they can contain unnecessary amounts of acetaminophen. Also, she writes, natural cough remedies like a spoonful of honey can be just as effective (or more effective) than medication.
Mucinex is a brand of over-the-counter cold and flu medication, with products for cough and chest congestion, sinus congestion and more.
Some believe it might be because of the way guaifenesin helps to loosen the mucus in the respiratory tract. It is hoped that if it can thin and loosen that mucus, it can also do the same for cervical mucus, which is naturally thin and accommodating during ovulation, or the “fertile window” of a menstrual cycle, to aid sperm swimming up to the egg.
Determining the risk of the other active ingredients found in Mucinex is a little trickier. Dextromethorphan is a cough suppressant that works by interfering with the “cough” signal in your brain. Guaifenesin works by loosening the mucus in your chest. There are some reports of a small risk of neural tube defects linked to guaifenesin, but the evidence is inconclusive. Its listed in a report by the American Academy of Family Physicians as “might be unsafe during first trimester.” In the same report, dextromethorphan is listed as “appears to be safe in pregnancy,” but as is true for many drugs and ingredients, there isnt enough evidence to say conclusively either way.
Acetaminophen, a widely used painkiller and fever reducer that may be advised for pregnant women but can also be harmful in high doses, may also be present in Mucinex.
