Drug Overview

HyVee® is a medication designed to help relieve the symptoms of severe cold and flu during the daytime. It contains a combination of active ingredients: acetaminophen (a pain reliever and fever reducer), phenylephrine HCl (a nasal decongestant), dextromethorphan HBr (a cough suppressant), and guaifenesin (an expectorant). Together, these ingredients work to temporarily alleviate common cold and flu symptoms such as nasal and sinus congestion, cough, minor aches and pains, headaches, fever, and sore throat.

This medication helps reduce swelling in the nasal passages, making it easier for you to breathe through your nose. It also promotes drainage of the nasal and sinus areas and helps loosen mucus, making coughs more productive by clearing out bothersome phlegm.

Uses

This medication is designed to help you feel better when you're dealing with common cold or flu symptoms. It can temporarily relieve issues like nasal and sinus congestion, cough from minor throat and bronchial irritation, and even minor aches and pains. If you're experiencing a headache, fever, or sore throat, this medication can also provide some relief.

In addition to easing these symptoms, it works to reduce swelling in your nasal passages, making it easier for you to breathe through your nose. It promotes drainage in your nasal and sinus areas, helping to clear out mucus. By loosening phlegm and thinning bronchial secretions, it can make your coughs more productive, allowing you to clear out bothersome mucus from your airways.

Dosage and Administration

It's important to take this medication exactly as directed to ensure your safety. You should not exceed 4 doses within a 24-hour period. If you are an adult or a child aged 12 years and older, the recommended dosage is 2 caplets every 4 hours.

For children aged 4 to under 12 years, it's best to consult a doctor before giving them this medication. If your child is under 4 years old, do not use this medication at all. Always follow these guidelines to avoid any potential overdose and ensure effective treatment.

What to Avoid

You should avoid using this medication if you are currently taking any other drug that contains acetaminophen, whether it's a prescription or over-the-counter product. If you're unsure whether a medication contains acetaminophen, please consult your doctor or pharmacist for clarification. Additionally, do not use this medication if you are taking a prescription monoamine oxidase inhibitor (MAOI), which is a type of drug used for depression, psychiatric conditions, or Parkinson's disease, or if you have stopped taking an MAOI within the last two weeks. Again, if you are uncertain about your medications, it's best to ask a healthcare professional.

Side Effects

You should be aware that taking more than 8 caplets in 24 hours, using other medications with acetaminophen, or consuming 3 or more alcoholic drinks daily while using this product can lead to severe liver damage. Additionally, acetaminophen may cause serious skin reactions, including skin reddening, blisters, or rash. If you experience any of these symptoms, stop using the product and seek medical help immediately.

If you have a severe sore throat that lasts more than 2 days or is accompanied by fever, headache, rash, nausea, or vomiting, consult a doctor right away. It's also important to stop use and contact a healthcare professional if you feel nervous, dizzy, or have trouble sleeping, or if your pain or cough worsens or lasts longer than specified. Always seek medical advice if you have existing health conditions like liver disease, heart disease, or if you are taking blood thinners like warfarin. Remember, taking more than the recommended dose can lead to serious health issues, so if you suspect an overdose, get medical help immediately.
