The Complete Guide to Vegan Cough Medicine

T

Note: Most medications are not strictly vegan.

But some are closer than others.

And even strict vegans often use cough medicine, which I’ll explain in more detail shortly.

Why Wouldn’t Cough Medicine Be Vegan?

There are 4 main issues that can cause a particular cough medicine to not be vegan friendly. Some of these are a bit controversial:

  1. Animal testing – Just about all medicine is required to be tested on animals currently. For example, Tylenol tests on animals.
  2. Clearly non-vegan ingredients – Gelatin is common in soft gel cough medications (not syrups), and honey is fairly common in cold medication.
  3. Glycerin – While glycerin can be vegan, it’s not usually clearly labelled on cough medicine if it’s from a vegetable or animal source.
  4. Artificial colors – Artificial colors like red 4, red 40, blue 1, etc., are surrounded with ongoing animal testing. Here’s a full post on why I don’t consider artificial colors to be vegan. You may have a different personal opinion on these, and that’s fine.

I’ve gone over all the top cough medicine brands below, and they all contain glycerin and some artificial colors at the very least. Again, though, the glycerin may be from a plant source, we just can’t say for sure.

So why do many vegans still use cough medicine?

The funny thing is that the active ingredients in cough medicine, usually acetaminophen and dextromethorphan, are both synthetic ingredients that really don’t need to be tested on animals any more.

All these other issues are theoretically avoidable, and hopefully will be one day.

I’d like to go over a quote by the Vegan Society:

Veganism is a way of living which seeks to exclude, as far as is possible and practicable, all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose.

If you’re coughing up a lung, I don’t think many vegans would say it’s practical to avoid cough medicine (that’s as close to vegan as possible).

In the worst case, in terms of animal suffering, most cough medicine is very low on that spectrum.

If you don’t want to take cough medicine because of those above issues, I completely understand. In that case, your best option is to make your own.

This is the best vegan homemade cough medicine I have found. Obviously it’s not going to be as good as NyQuil or whatever, but can help ease your coughing.

Common Cough Medicines (and Whether or Not They Are Vegan)

Almost all popular cough medicines have the same ingredients these days.

They work really well, just aren’t necessarily the most vegan friendly for the reasons above.

Regardless, I’ll break down the ingredients that you may not consider vegan, and you can decide for yourself how you feel about them.

On a personal note, I don’t consider any of these to be vegan, but wouldn’t be against taking them when very sick for practical reasons, as discussed before.

Is DayQuil or NyQuil Vegan?

dayquil

It’s pretty easy to find DayQuil and NyQuil in stores.

Here are the potential non-vegan ingredients in DayQuil to start:

Yellow No. 6, flavor, glycerin

Not too bad. Both “flavor” and “glycerin” could be from plant or animal sources, it’s just not specified.

In terms of artificial colors, only Yellow #6 is in DayQuil.

NyQuil has very similar ingredients, but has more artificial coloring. Again, here are the controversial ingredients:

Yellow No. 10, FD&C Yellow No. 6, FD&C Green No. 3, flavor, glycerin

So by strict vegan standards, DayQuil and NyQuil are not vegan. But they aren’t too far off, and you may consider them okay for practical reasons.

Is Robitussin Vegan?

Robitussin

Robitussin has a few different cough medicines. Avoid the honey flavored ones of course, but we’ll look at the traditional Robitussin cough medicine here.

Here are the ingredients in Robitussin that are potentially non-vegan:

FD&C blue #1, red #40, glycerine, natural flavors

Again, artificial colors, which you’ll find in just about all cough syrups.

Additionally, it has glycerin and natural flavors.

Like glycerin(e), natural flavors can be vegan or not vegan. They can be derived from both animal and plant sources. It’s not clear which one here, although I would suspect that the natural flavors here are from plant sources.

Again, like the rest, Robitussin likely isn’t vegan, even if we ignore the animal testing aspect, but it’s not too far off.

Is Mucinex Cough Syrup Vegan?

Mucinex

The last of the very popular cough syrups that I wanted to include is Mucinex.

It has virtually identical ingredients to Robitussin, and the list of potential non-vegan ingredients is the exact same:

FD&C blue #1, red #40, glycerine, natural flavors

In case you skipped down to this point from the start of the post, both glycerine and natural flavors can be derived from plant or animal sources. Since it’s not specified on the product, we can’t know for sure.

Artificial colors themselves are synthetic, but are frequently tested on animals. They’re fairly controversial among vegans.

Summary: Which Cough Medicine is Best for Vegans?

No easy to find cough medicine is 100% vegan friendly, and they all appear to be just about the same.

Most cough medicines are likely tested on animals, have artificial colors (which some vegans avoid), and ambiguous ingredients like glycerin that may or may not be vegan.

Since veganism is mostly about reducing animal harm whenever possible, most vegans would be okay with taking any common cough syrup above (or similar ones that don’t have honey or gelatin). It can reasonably argued that there are just no practical alternatives.

If you’re really conflicted, you can make your own cough syrup, but the effectiveness will vary depending on the recipe. It likely won’t be as effective as store-bought ones in any case.

This is a pretty grey area for vegans, so if you’d like to discuss anything or have a question, just let me know in a comment below. I’m happy to revisit this topic.

An alternative is to look for vegan throat lozenges and cough drops, as a decent amount of those are vegan.

  • Such lovely comments, Dale. I’ve been vegan for forty years & only now am realising the massive infiltration of animal products/by-products in almost every area. After reading much material on animal testing I now try my bets to avoid all unnecessary products. As carer to my mum, who has dementia, is 92 and has acute scoliosis, she now finds it almost impossible to breathe when she catches cold. We have always gone down the natural road with mum as she too in her day opted for non-chemical. Now, after being diagnosed with vascular dementia around ten years ago, she is on alpha lipoic acid, turmeric, coconut oil and omega 3 (all vegan and organic) . I was told years ago that her body was then beginning to ‘shut down’ because she was refusing food and fluids. Turns out it was the high dose of diazepam they’d put her on to make her less aggressive. That’s when I took over. I weaned her off the drug and she has been on natural since. Her memory is improving, her fear has gone, she recognises people, and apart from her now physical deterioration, she is feisty, lovable and full of humour! She is vegan like myself, and has had no trouble in the toilet department! I used to visit an elderly lady around the same age who had stocked piled hundreds of boxes of powders to eliviate her chronic constipation. (She ate a lot of meat and dairy and had had two major heart attacks). ATM however, I am torn between giving mum some cough medicine as she is now vomiting in her sleep due to catarrh build up on her lungs, because of the compression on her rib cage from the spine curveture. I may have to use some, and reading your thoughts about the do’s & dont’s of veganism has really helped. I too have always believed that we do what we can to the best of our situations. I’m doing my small part too!

    • The artificial colors still might be an issue for many, but it’s good to know that the medicine itself isn’t tested on animals, thanks Chris.
