Drug Overview

NyQuil Cold & Flu is a nighttime medication designed to help relieve common cold and flu symptoms. It contains three active ingredients: acetaminophen (a pain reliever and fever reducer), dextromethorphan HBr (a cough suppressant), and doxylamine succinate (an antihistamine). Together, these ingredients work to temporarily alleviate symptoms such as minor aches and pains, headaches, sore throats, runny noses, sneezing, fevers, and coughs caused by throat and bronchial irritation.

This product is suitable for individuals aged 12 and over and comes in a cherry-flavored liquid form. With its combination of ingredients, NyQuil Cold & Flu aims to provide you with relief so you can rest more comfortably during the night when you're feeling unwell.

Uses

This medication is designed to help you feel better when you're dealing with common cold or flu symptoms. It can temporarily relieve minor aches and pains, headaches, sore throats, runny noses, sneezing, fevers, and coughs caused by minor irritation in your throat and bronchial tubes.

You can rely on this treatment to ease your discomfort and help you get through those pesky cold or flu days. Remember, it’s always a good idea to consult with a healthcare professional if you have any questions or concerns about your symptoms.

Dosage and Administration

It's important to follow the dosing instructions carefully to ensure your safety and effectiveness of the medication. You should not take more than the directed amount, and make sure not to exceed 4 doses within a 24-hour period. To measure your dose accurately, use only the dosing cup that comes with the medication; avoid using any other measuring devices.

For adults and children aged 12 years and older, the recommended dose is 30 mL every 6 hours. If your child is under 12 years old, do not use this medication. Additionally, if you are using other Daytime or Nighttime products, be sure to read each label carefully to avoid taking too much.

What to Avoid

You should avoid using this product if you are currently taking a prescription monoamine oxidase inhibitor (MAOI), which is a type of medication used for depression, certain psychiatric conditions, or Parkinson's disease. Additionally, you should not take this product for at least two weeks after stopping an MAOI. If you're unsure whether your medication contains an MAOI, please consult your doctor or pharmacist.

It's also important not to use this product in combination with any other medications that contain acetaminophen, whether they are prescription or over-the-counter. If you have any doubts about whether a drug contains acetaminophen, again, please ask your healthcare provider for guidance. Taking these precautions can help you avoid potential health risks.

Side Effects

You should be aware that taking more than 4,000 mg of acetaminophen in a 24-hour period, using it with other medications that contain acetaminophen, or consuming three or more alcoholic drinks daily while using this product can lead to severe liver damage. Additionally, acetaminophen may cause serious skin reactions, which can include symptoms like skin reddening, blisters, or rash. If you experience any of these skin reactions, stop using the product and seek medical help immediately.

While using this medication, you might feel unusually excited, especially if you are a child, or experience significant drowsiness. It's important to avoid alcohol, as it can increase drowsiness, and be cautious when driving or operating machinery. If your pain or cough worsens or lasts more than seven days, or if you develop new symptoms, you should consult a doctor. Always seek medical advice if you have liver disease, glaucoma, or other specific health concerns before using this product.
