Vicks Nyquil is a well known multi-symptom medication that is used in treating the conditions like pain, cold, cough, flu, sinus congestion, sneezing, runny nose, allergies, and upper respiratory infections. It is available in both liquid and capsule forms.

What Does Nyquil Do?

The Nyquil multi-symptom is a combination of analgesic, cough suppressant, antihistamine, and decongestant. Multiple active ingredients found in Nyquil work towards treating a single or group of these symptoms.

The analgesic Ingredient found in Nyquil suppresses the production of a chemical called prostaglandin. When the cells do not release this chemical, pain receptors get nothing to conduct. Apparently our brain will not receive the pain messages. It stops sensing the pain instantly.

The Cough suppressant Ingredients reduce the dry as well as an unproductive cough.

The antihistamine ingredients block the production of histamine that in turn reduces the symptoms such as inflammatory responses, sneezing and watery eyes. It is commonly suggested for those with body pain, fever or aches. It’s also responsible for the sleepiness effect caused by Nyquil.
