TL;DR
Yes, CVS DayQuil products are considered gluten-free. DayQuil does not contain any wheat, barley, rye or other gluten-containing ingredients. For those with celiac disease or gluten sensitivity, DayQuil liquid and capsules can be safely consumed without concern for gluten exposure.
What is DayQuil?
DayQuil is an over-the-counter medication manufactured by Procter & Gamble. It is intended to provide temporary relief of common cold and flu symptoms such as:
- Cough
- Sore throat
- Headache
- Minor aches and pains
- Fever
- Runny nose
- Sneezing
DayQuil comes in both liquid and capsule formulations. The active ingredients depend on the specific product, but commonly include combinations of:
- Acetaminophen – Pain reliever/fever reducer
- Dextromethorphan – Cough suppressant
- Phenylephrine – Nasal decongestant
- Guaifenesin – Expectorant to thin mucus
DayQuil is designed to be taken during daytime hours. It contains stimulants like phenylephrine which can disrupt sleep. The nighttime counterpart is NyQuil, which contains sedating antihistamines instead of stimulants.
What is gluten?
Gluten is a general name for the proteins found in wheat, rye and barley. Some examples of foods containing gluten include:
- Bread
- Pasta
- Cereal
- Beer
- Cakes and pies
- Cookies and crackers
For most people, gluten poses no health concerns. However, for those with celiac disease or non-celiac gluten sensitivity, gluten can trigger an abnormal immune response and cause damage to the small intestine. Even small amounts of gluten can cause issues, so these individuals need to follow a strict gluten-free diet.
Symptoms of gluten exposure
When someone with celiac disease or gluten sensitivity consumes gluten, it can cause a range of gastrointestinal and non-gastrointestinal symptoms including:
- Diarrhea
- Abdominal pain
- Bloating
- Gas
- Constipation
- Nausea
- Vomiting
- Headaches
- Fatigue
- Joint pain
- Skin rash
- Tingling or numbness in hands/feet
Symptoms can range from mild to severe based on the amount of gluten ingested and the individual’s sensitivity levels. Some people experience symptoms immediately after eating gluten, while for others it may take hours or days for issues to arise.
Why follow a gluten-free diet?
The only treatment for celiac disease is following a strict lifelong gluten-free diet. This allows the gut to heal and prevents further damage. With non-celiac gluten sensitivity, a gluten-free diet may also be necessary to manage symptoms.
Adhering to a gluten-free diet involves avoiding all foods and products containing wheat, barley, rye and their derivatives. This includes checking labels on packaged goods like sauces, dressings and seasonings that could contain hidden sources of gluten.
For medication, it’s also important to check that pills, capsules and liquids are gluten-free. Since medications are absorbed into the bloodstream, gluten intake could still trigger a reaction even if the digestive system doesn’t come into direct contact with it.
Is DayQuil gluten-free?
The good news is that yes, DayQuil products are labeled gluten-free. DayQuil liquid and capsules do not contain any ingredients derived from wheat, barley, rye or other gluten sources. Some individuals with celiac disease or gluten sensitivity may still wish to check with the manufacturer to inquire about shared equipment and facility practices. However, DayQuil can be considered gluten-free.
DayQuil Liquicaps
The active ingredients in DayQuil Liquicaps (capsule format) include:
- Acetaminophen – Pain reliever/fever reducer

- Acacia
- Corn starch

As you can see, the capsule contains gelatin but no gluten-containing ingredients. Gelatin is sometimes a concern for those following a gluten-free diet, but gelatin is not derived from gluten sources. The corn starch and other ingredients are also gluten-free.
DayQuil Severe Liquicaps
DayQuil Severe Liquicaps include the additional active ingredient Guaifenesin, an expectorant. Otherwise, the inactive ingredients are the same gluten-free list as regular DayQuil Liquicaps.
DayQuil Capsules
The ingredients in DayQuil capsules (not liquicaps) include:
Active ingredients:
- Acetaminophen – Pain reliever/fever reducer
- Dextromethorphan – Cough suppressant
- Phenylephrine – Nasal decongestant
Inactive ingredients:

Active ingredients:
- Acetaminophen – Pain reliever/fever reducer
- Dextromethorphan – Cough suppressant
- Guaifenesin – Expectorant
- Phenylephrine – Nasal decongestant
Inactive ingredients:

DayQuil Severe Cold & Flu Relief Liquid
DayQuil Severe Cold & Flu Relief liquid has the same gluten-free ingredient list as the regular strength formula.
Why is DayQuil gluten-free?
DayQuil is gluten-free because it is designed to temporarily relieve cold and flu symptoms, not gastrointestinal issues. It focuses on controlling upper respiratory symptoms like cough, congestion and sneezing along with body aches and fever.
Since it does not involve the digestive system, there is no medical need for DayQuil to contain gluten. The richness of wheat or barley proteins would not enhance the product’s effectiveness. Keeping the liquid and capsules gluten-free ensures they are safe for individuals with celiac disease or gluten intolerance.
Verifying gluten-free status
Checking medication ingredients against gluten sources is the first step in determining gluten-free status. However, some individuals with celiac disease or gluten sensitivity also like the extra assurance of calling the manufacturer directly. This allows you to ask additional questions including:
- Are any gluten-containing grains used in facility equipment cleaning?
- Does any shared facility equipment also process wheat/barley/rye?
- Are there any other possible sources of cross-contamination?
Asking these types of questions provides extra confirmation that the product is gluten-free from start to finish. The customer service team should be able to look into manufacturing details and processes to address your concerns.
Finding gluten-free cold medicine
When evaluating over-the-counter cold and flu medications, look at both the active and inactive ingredients for potential gluten-containing components:
- Active ingredients – These directly treat symptoms and shouldn’t raise any gluten concerns in cold medicine. Ingredients like acetaminophen, dextromethorphan, guaifenesin and phenylephrine are gluten-free.
- Inactive ingredients – Fillers, binders and coatings like starch or flour could add traces of gluten. Checking the inactive list on DayQuil revealed no problematic ingredients.
Call the manufacturer if you still have any concerns. Look for labels clearly marked “gluten-free” for added assurance.
Beyond DayQuil, some other gluten-free cold and flu medication options include:
- NyQuil
- Sudafed
- Tylenol Cold & Flu
- Advil Cold & Sinus
- Theraflu
- Mucinex
- Coricidin HBP
- Benadryl
However, always check labels and ingredients lists carefully, or contact the manufacturer directly, each time before taking a new medication. Formulations can change over time.
Precautions when taking DayQuil
Although DayQuil products check out as gluten-free, it is always wise to take some basic precautions when taking any medication:
- Read the label each time before use to ensure the ingredients list has not changed and the product is still marked gluten-free.
- Check dosing guidelines based on your age and medical history. Do not exceed recommended amounts.
- Be aware of potential interactions with any other medications or supplements you take.
- Talk to your pharmacist or doctor if you have any concerns about taking DayQuil with your individual health status and medication regimen.
By following usage guidelines and verifying gluten-free status, DayQuil can be a safe and effective option for temporary relief of cold and flu symptoms in people with celiac disease or gluten intolerance.
Other tips for choosing gluten-free medications
Some additional best practices for identifying gluten-free drug choices include:
- Check pills and capsules – Look at inactive fillers and binders in tablets and capsules which could potentially contain gluten.
- Look at liquids – Suspending agents like wheat starch could introduce gluten in liquid preparations.
- Call the manufacturer – Verify gluten-free production if you have any concerns about cross-contamination.
- Research generics – Generic drugs have the same active ingredients but different inactive fillers that may affect gluten content.
- Consider natural options – Substituting supplements like vitamin C, zinc or elderberry syrup provides gluten-free symptom relief.
Empower yourself by getting informed about medication ingredients and manufacturing processes. With the proper knowledge and precautions, you can safely navigate over-the-counter cold relief options while following your gluten-free diet.
The bottom line
DayQuil offers a gluten-free way to get relief from cough, congestion and other cold and flu symptoms. Both the liquid and capsule formulas are made without any gluten-containing ingredients and can be safely taken by those with celiac disease and gluten intolerance. Just remember to always double-check the label and ingredients list before using. With a few simple precautions, DayQuil can provide gluten-free and effective temporary symptom relief.
