The ketogenic diet, characterized by its high-fat, moderate-protein, and very low-carbohydrate composition, has gained considerable popularity for its potential health benefits, including weight loss, improved blood sugar control, and enhanced cardiovascular health. Many individuals adopt this lifestyle to manage existing health conditions. However, navigating medication use while adhering to a ketogenic diet can present challenges. This article delves into the question of whether NyQuil, a common over-the-counter (OTC) medication for cold and flu symptoms, is compatible with a ketogenic lifestyle, examining its ingredients and potential impact on ketosis.
Understanding the Ketogenic Diet and Ketosis
The primary goal of a ketogenic diet is to shift the body's primary fuel source from glucose (derived from carbohydrates) to ketones, which are produced from the breakdown of fats. This metabolic state, known as ketosis, is achieved by drastically reducing carbohydrate intake, typically to between 20 and 50 grams per day. When carbohydrate intake is limited, the liver converts fats into ketones, which then circulate in the bloodstream and are used by the body as an alternative energy source.
Many chronic conditions, such as obesity, type 2 diabetes, and hypertension, are associated with elevated blood glucose and insulin levels. The ketogenic diet can help address these issues by promoting weight loss, improving insulin sensitivity, and lowering blood pressure.
Medication and Ketosis: Potential Interactions
While the ketogenic diet offers numerous health benefits, it's essential to be aware of potential interactions between the diet and certain medications. Some medications can interfere with ketosis by raising blood sugar or insulin levels. However, the good news is that as the keto diet improves your health, you may need lower doses or can stop your prescriptions altogether.
Important Note: Never stop or alter your medication dosage without consulting your doctor or pharmacist.

Medications That May Interfere with Ketosis
- Diabetes Medications: Drugs like insulin and metformin, commonly prescribed for type 2 diabetes, work to lower blood glucose levels and regulate insulin. Since ketosis relies on low insulin levels, these medications can potentially hinder the process. However, as the ketogenic diet improves insulin sensitivity, the need for these medications may decrease.
- Steroids: Steroids, such as prednisone, are potent anti-inflammatory drugs that can raise blood sugar and insulin levels, thereby interfering with ketosis.
- Antipsychotic and Central Nervous System Medications: Some drugs used to treat mental health conditions can increase insulin levels, making it more difficult to achieve ketosis.
Common Over-the-Counter Medications: Hidden Carbs
It's crucial to be aware that many OTC medications, including cough syrups and cold remedies, can contain significant amounts of carbohydrates in the form of added sugars. These hidden carbs can quickly disrupt ketosis.
NyQuil: A Closer Look at its Ingredients
NyQuil is a popular OTC medication used to relieve cold and flu symptoms such as cough, nasal congestion, headache, and fever. It is available in various formulations, including liquid, LiquiCaps, and tablets. To determine whether NyQuil is keto-friendly, it's essential to examine the ingredients of each formulation.
NyQuil Liquid
The liquid formulation of NyQuil typically contains the following active ingredients:
- Acetaminophen (pain reliever and fever reducer)
- Dextromethorphan HBr (cough suppressant)
- Doxylamine succinate (antihistamine)
However, the inactive ingredients in NyQuil liquid are where the potential carbohydrate concerns lie. These ingredients often include:
- High Fructose Corn Syrup
- Alcohol
- Acesulfame Potassium
- Citric Acid
- D&C Yellow No. 10
- FD&C Green No. 3
- FD&C Yellow No. 6
- Flavor
- Polyethylene Glycol
- Propylene Glycol
- Purified Water
- Saccharin Sodium
- Sodium Citrate
High fructose corn syrup is a significant source of carbohydrates and can quickly kick you out of ketosis. The inactive ingredients in Original NyQuil include: Acesulfame Potassium, Alcohol, Citric Acid, D&C Yellow No. 10, FD&C Green No. 3, FD&C Yellow No. 6, Flavor, High Fructose Corn Syrup, Polyethylene Glycol, Propylene Glycol, Purified Water, Saccharin Sodium, Sodium Citrate. The inactive ingredients in Cherry NyQuil include: Acesulfame Potassium, Alcohol, Citric Acid, FD&C Blue No. 1, FD&C Red No.

NyQuil LiquiCaps and Tablets
NyQuil LiquiCaps and tablets may have a different ingredient profile than the liquid formulation. In general, capsules and tablets are less likely to contain significant amounts of carbohydrates. It is important to carefully read the label and ingredient list to determine if added sugars or other sources of carbs are present.
The Impact of NyQuil on Ketosis: A Personal Experiment
One individual shared their experience of taking NyQuil while following a ketogenic diet. A few weeks ago I was feeling pretty under the weather. I had a headache, fatigue, cough, and nasal congestion. I felt bad enough to be uncomfortable, but not bad enough to call in sick to work. The only issue is that my shift is an overnight shift for multiple consecutive days, and while I’m on these shifts, my sleep is pretty disrupted. I average about 5:30 - 6:30 hours of sleep… the only thing is, I know my body needs AT LEAST 7:30 to feel optimal. I tried for a few days to sleep it off, but my sleep schedule was just too screwed up and some nights I found myself only getting 4:00-4:30 hours of sleep. As a last resort I turned to Nyquil to help with some symptomatic relief and as a sleep aid. I have to admit that those few nights I took Nyqil, I had the best sleeps of my life. I know that using sleep aids like this supposedly disrupts your normal sleep cycle and isn’t as restorative as normal sleep, but in my situation, my sleep cycle was already screwed up, so things could only get better.
They noticed that it was a lot harder for me to get into ketosis that week. I thought It may have had something to do with the amount of stress my body was under and didn’t quite put two and two together until one night I started looking at the ingredient list. Upon examining the ingredient list, they discovered that NyQuil contained 19 grams of carbohydrates per dose. No wonder it was so hard for me to get into ketosis that week… I was dosing my body with 19 grams of carbs before I went to bed!
The individual's experiment revealed that taking NyQuil significantly impacted their ketone levels and blood glucose. On both occasions when they took NyQuil, their ketone levels dropped, and their blood glucose levels increased. It’s pretty clear what effect taking Nyquil had on me. On both occcasions, the following AM Ketones demonstrated a drop first from 0.4 to 0.2 mmol and then from 0.9 to 0.3 mmol. This was accompanied with a bump in my blood glucose, from 92 to 99 and from 89 to 92. This demonstrates that the carbohydrates in NyQuil can indeed disrupt ketosis. My diet hadn’t changed… I was still taking in 30 gm or less of carbs as per the Carb Nite Solution but taking that Nyquil really derailed my efforts to get into or stay in ketosis.
