The Truth About Cough Medicine
Updated: Apr 3
Everywhere we go, there are toxins. We live in a toxin-filled world. Unfortunately, it's hard to decipher what products possess toxins. Over-the-counter medications are some of the most common places to find toxins–especially cough medicine, which is meant to make you feel better.

Dextromethorphan, also known as DXM, was approved by the FDA in 1958 and can be found in at least 70 common over-the-counter (OTC) cough and cold medicines, including the “best-selling” Robitussin. DXM has side effects like lethargy, paranoia, hallucinations, and chemical psychosis. Dextromethorphan is a cough suppressant that is advised not to be given to children under 4.
Other known effects of DXM include:
Hot flashes
Nausea, vomiting, and dizziness
Lack of coordination
Panic attacks or seizures
Impaired judgment
Sweating
Lethargy or drowsiness—or hyperactivity
Slurred speech
High blood pressure
Rapid eye movement
Rash
Racing or pounding heartbeat
Regular abuse of DXM at high doses can lead to chemical psychosis (1).
The worst part is that this isn't even the most concerning ingredient, which we will discuss after the top 10 best-selling cough medicines on Amazon, which surprisingly didn't have the absolute worst options, some decent ones, actually.

The Top 10 Best-Selling Cough Syrups on Amazon
When I researched the top 10 best-selling cough syrups on Amazon, I was pleasantly surprised to find the first two to be decent products. Of course, as you work down the list, it gradually worsens.

Toxic Ingredients Found In Cough Medicine
Acetaminophen, commonly known as Tylenol, is a pain killer that has been linked to an increased risk of health problems when used in larger doses or long-term. Some risks of acetaminophen include damaging the liver and kidneys, depleting levels of glutathione, cardiometabolic risk, linked to cancer, affecting emotional processing, may have neurodevelopment consequences during pregnancy, linked to Steven’s-Johnson Syndrome and asthma, and endocrine disruption.

Ascorbic Acid is a synthetic vitamin C usually derived from GMO corn. According to North Coast Organic, plenty of evidence shows that consuming ascorbic acid, especially in high doses, should be avoided (2).
Carboxymethylcellulose Sodium is an active ingredient in common eye lubricants but is used as a thickening agent in cough syrups. Carboxymethylcellulose sodium, also known as cellulose gum, is indigestible. Your stomach and intestines will not be able to break it down and absorb it. An article was written in 2015 that showed that consuming emulsifiers like this one can impact the gut microbiota, promoting colitis and metabolic syndrome. The same goes for croscarmellose sodium; it is also an emulsifier that affects gut microbiota (3).
Citric Acid naturally occurs in oranges, lemons, and other citrus fruits and is perfectly safe. Citric acid is also naturally sourced from Aspergillus niger-black mold (4). Health problems associated with this type of mold include respiratory infections, allergic reactions, and inflamed lungs (5).
Corn Syrup is 100 percent glucose and should be avoided by people with diabetes or prediabetes (6).
Food Coloring has been linked to neurological disorders like ADHD, cancer, allergies, learning disabilities, irritability, and aggressiveness (7). To learn more about the risks associated with consuming food coloring, check out my article, The Truth About Food Coloring, here.
Gelatin is a protein sourced by boiling animal skin, tendons, cartilage, ligaments, and or bones in water and is usually obtained from cows, pigs, or fish (8). Gelatin consumption can cause symptoms of upset stomach, burping, bloating, and allergic reaction. Some experts worry that gelatin has a risk of being contaminated with certain animal diseases, and how they aren't sure if it's safe for pregnant or breastfeeding women or children (9).
Guaifenesin is an expectorant used to help loosen congestion in your chest and throat. Guaifenesin also has a long list of side effects like diarrhea, dizziness, headache, hives, nausea or vomiting, skin rash, stomach pain, and upset stomach (10).
High Fructose Corn Syrup is sweeter than sugar and the body much more quickly absorbs it. Fructose is a type of simple sugar that makes up 50% of table sugar (sucrose). Overeating high fructose corn syrup can lead to insulin resistance, obesity, type 2 diabetes, and high blood pressure (11).
Polyethylene Glycol is an active ingredient in laxatives like MiraLAX. Polyethylene Glycol has a long list of side effects, including bloating, gas, upset stomach, dizziness, increased sweating, abdominal distension and pain, borborygmi, nausea, vomiting, diarrhea, flatulence, abdominal cramping, perianal inflammation and soreness, allergic reaction, severe or bloody diarrhea, rectal bleeding, blood in your stool, and painful or worsening stomach pains (12).
Povidone-Iodine is typically applied topically to decrease the risk of infection (13). Surprisingly, ingestion of this ingredient can result in stomach upset, thyroid dysfunction, and gastrointestinal tract burns. In severe cases, heart and kidney failure may occur (14).
Sodium Benzoate is a synthetically-manufactured preservative added to some sodas, packaged foods, and personal care products to prolong shelf life (15). This ingredient is used to extend the shelf life of cough syrup and was also reported to alter sperm quality and function in a 2018 study (16). A significant concern over the use of sodium benzoate is its ability to convert to benzene, a known carcinogen when exposed to vitamin C (17).
