What You'll Learn

The liquid form of Nyquil contains 10% alcohol
NyQuil is an over-the-counter medication from Vicks that helps treat symptoms associated with colds and the flu, such as coughing, a runny nose, and aches and pains. It is available in different formulations and combinations of different active ingredients.
It is important to note that alcohol is not an active ingredient in Nyquil, meaning it does not directly relieve flu and cold symptoms. Nevertheless, consuming alcohol while taking Nyquil is not recommended as it can worsen side effects like dizziness and drowsiness and even lead to liver damage. This is because both alcohol and Nyquil's active ingredient, acetaminophen, are broken down by the liver, and combining the two can place additional stress on this organ.
While Vicks does produce alcohol-free Nyquil medications in both liquid and capsule forms, it is always important to read the medication label and check with your doctor or pharmacist to determine which product is safe for you.

Alcohol-free Nyquil products can still cause drowsiness
Nyquil is an over-the-counter medication from Vicks that treats symptoms such as coughing, a runny nose, and aches and pains associated with colds and the flu. It is available in different formulations and combinations of different active ingredients.
Many Nyquil products contain 10% alcohol as a solvent to dissolve the active ingredients. However, Vicks also produces alcohol-free Nyquil medications in both liquid and capsule forms.
While these alcohol-free alternatives exist, it is still advised to avoid drinking alcohol when taking Nyquil. This is because Nyquil can cause drowsiness, which alcohol consumption may exacerbate. Although Vicks does not specify the Nyquil ingredients that cause drowsiness, scientists know that doxylamine succinate and dextromethorphan can have this effect. Therefore, even alcohol-free Nyquil products may contain ingredients that cause drowsiness.
In addition, acetaminophen, another ingredient in Nyquil, is broken down by the liver, as is alcohol. Therefore, combining the two can place additional stress on the liver and lead to liver damage.

Nyquil treats symptoms like coughing, aches and pains
Nyquil is an over-the-counter medication that treats symptoms associated with colds and the flu. It is available in different formulations and combinations of active ingredients. While not all Nyquil products contain alcohol, many do, with several containing 10% alcohol. Alcohol is not an active ingredient in Nyquil, but it is used as a solvent to dissolve the active ingredients. The active ingredients in Nyquil include acetaminophen, dextromethorphan, and doxylamine succinate.
Nyquil treats symptoms such as coughing, aches and pains, fever, runny nose, sneezing, sore throat, and headache. Acetaminophen is a pain reliever and fever reducer, dextromethorphan suppresses the signals in the brain that trigger the coughing reflex, and doxylamine blocks histamine, which causes allergy symptoms such as watery eyes, runny nose, and sneezing.
It is important to note that Nyquil can cause drowsiness, and consuming alcohol with Nyquil can exacerbate this side effect and lead to liver damage. Therefore, it is recommended to avoid consuming alcohol with Nyquil products and to exercise caution when driving or operating machinery. Additionally, Nyquil should not be used to treat long-term coughs or in children under the age of six without medical advice.

Combining Nyquil with alcohol can lead to liver damage
Nyquil is an over-the-counter medication that treats symptoms associated with colds and the flu, such as coughing, a runny nose, and aches and pains. It is available in different formulations and combinations of different active ingredients.
Many Nyquil products contain 10% alcohol as a solvent to dissolve the active ingredients. However, the alcohol content is not meant to relieve flu and cold symptoms. The active ingredients in Nyquil work together to relieve symptoms. For example, acetaminophen, also known as paracetamol, is a drug that eases pain and reduces fever.
While there are alcohol-free Nyquil products available, it is still advised to avoid consuming alcohol when taking these medications. This is because alcohol can enhance the effects of the active ingredients in Nyquil, leading to potentially harmful consequences. For example, the sedative effects of Nyquil can be exacerbated by alcohol, leading to increased drowsiness and dizziness.
Combining Nyquil with alcohol can also lead to liver damage. Both alcohol and acetaminophen, an active ingredient in Nyquil, are broken down by the liver. Heavy alcohol use and repeated acetaminophen use can lead to liver damage. Consuming both places additional stress on the liver, which can lead to serious complications.
Therefore, it is essential to follow the directions on the package labeling and avoid consuming alcohol when taking Nyquil products.
