Dayquil is a popular medication for the relief of symptoms from colds, influenza and allergies. It is a combination drug that contains acetaminophen, chlorpheniramine maleate, dextromethorphan hydrobromide and pseudoephedrine hydrochloride.
Acetaminophen helps to relieve fever or pain; while chlorpheniramine maleate relieves runny nose (rhinitis), sneezing (conjunctivitis) and itchy throat.
Dextromethorphan hydrobromide treats coughs by suppressing the urge to cough while pseudoephedrine hydrochloride stimulates your breathing passages in order to help you breathe easier during times of respiratory distress such as asthma attacks or during the common cold.
The product is not FDA approved for use in children under 12 years of age, or those who are prone to misuse Dayquil as a sleeping aid because it can cause insomnia and hallucinations.
In addition, people with liver diseases should take caution when using these drugs because they may experience increased side effects such as jaundice (yellowing skin), dark urine, abdominal pain or nausea.
If you have any questions about how this medication might affect your body please consult with your physician first before taking any medications that can inhibit central nervous system activity like acetaminophen, pseudoephedrine hydrochloride or dextromethorphan hydrobromide so that you will know if it’s safe for you.
