Side Effects of Mixing Nyquil and Alcohol

According to the makers of Nyquil, if patients with consuming Nyquil products drink alcoholic beverages more than 3 time once a day, they should consult with the professional healthcare. Mixing alcohol with Nyquil (some contain about 10% alcohol themselves) can cause side effects such as intoxication and drowsiness.

Nyquil is an over-the-counter medication commonly used for the relief of symptoms that occur with viral upper respiratory illnesses and allergies. There are many different formulations, for example Nyquil D, NyQuil Sinus, NyQuil Cough, and NyQuil Cold/Flu Multisymptom Relief.

The spectrum of side effects associated with each Nyquil formulation will vary slightly due to the fact that each Nyquil product contains different active ingredients. The active ingredients that are used in Nyquil products can include:

Acetaminophen– Also known as Tylenol or Paracetamol, Acetominophen is an over-the-counter pain reliever and fever reducer.  Consistence consumption of Acetominophen in overdosing will cause severe liver injury, and it can lead to problems mixing with alcohol.

Doxylamine succinate– This ingredient is an antihistamine that is used for temporary relief of rhinorrhea, sneezing, lacrimation, itching eyes, or oronasopharyngeal itching associated with allergic rhinitis (e.g., hay fever) or other upper respiratory allergies. However, doxylamine is also very sedating and is occasionally used in the short term treatment of insomnia.

Phenylephrine– This is a nasal decongestant used in many over-the-counter syrups, capsules and nasal sprays.

Dextromethorphan– This is a very common over the counter cough suppressant.

Pseudoephedrine– This a nasal decongestant. However, due to abuse potential, formulations that contain pseudoephedrine in the United States are now available only by asking a pharmacist.

The inactive ingredients of the Nyquil preparations will vary, as will the particular combination of the above active ingredients that is used in each formula. However, there is one ingredient that is consistent through out all available formulations of Nyquil.

Mixing Nyquil and Alcohol

Alcohol is similar as Nyquil that used in relieving the pain and it can be addicted easily too. If you take Nyquil with alcohol, it is like a recipe for disaster while mixing with both addictive substances. It has been known for alcoholics to drink Nyquil during the withdrawal of alcohol addiction – just replace one addictive substance with another one.

Due to the ingredient of acetaminophen, it is recommended to avoid mixing with other products that containing acetaminophen. If you do have to, you should monitor the dosages, and stop consuming it immediately once recovered.

Nyquil abused can be highly dangerous, the side effects will be more serious especially when mixing with alcohol. It’s important to bear in mind that you should prevent all alcohol products from taking Nyquil to be safer.
