Can you drink alcohol with NyQuil?

No, you should not pair alcohol and NyQuil together. Alcohol interacts with the active ingredients present in NyQuil and can cause a number of disturbing side effects. 

Let’s take a look. At NyQuil’s ingredients and discuss each one of them. 

  • Acetaminophen 
  • Dextromethorphan 
  • Doxylamine 

Acetaminophen and alcohol 

Alcohol and Acetaminophen should not be present in your body at the same time. This is because both of these chemicals are primarily metabolised by your liver (1). 

Since both are hepatotoxic in nature, the two at the same time can damage your liver. This is why it’s best to avoid using alcohol while you’re taking Acetaminophen, whether alone or in combination with other meds like NyQuil.

Dextromethorphan and alcohol

Dextromethorphan is a cough suppressant. Taking it concomitantly with alcohol can affect your mental alertness and can cause extreme sedation. The combined use should be avoided. 

Doxylamine and alcohol

Doxylamine is a sedative first-generation antihistamine. The combined use of Doxylamine with alcohol can dangerously cause CNS depression. 

This is because both Doxylamine and alcohol have depressing effects on your brain. Excessive use can significantly affect your breathing rate by causing respiratory depression. 

Alcohol should never be paired with sleep-inducing meds, including other sedative antihistamines like Diphenhydramine, benzodiazepines like Clonazepam, Alprazolam, Diazepam etc and typical sleeping pills like Zolpidem, Zaleplon, etc.

Pharmacist’s advice 

It’s best not to take alcohol and NyQuil at the same time. NyQuil contains active ingredients with short half-lives and the medication stays in your system for around 5-7 hours. You should at least wait for that long before drinking alcohol. This will reduce the risk of additive side effects.
