Drug Overview

H•E•B Nighttime SEVERE is a cold and flu medication designed to help you feel better when you're experiencing symptoms associated with these illnesses. 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 doxylamine succinate (an antihistamine). Together, these ingredients work to temporarily relieve common cold and flu symptoms such as nasal congestion, cough, minor aches and pains, headache, fever, sore throat, and runny nose.

This honey-flavored formulation is particularly useful for nighttime use, as it can help you sleep by alleviating cough and promoting freer breathing through the nose. By reducing swelling in the nasal passages and promoting drainage, H•E•B Nighttime SEVERE aims to provide you with comfort during your recovery.

Uses

This medication is designed to temporarily relieve a variety of common cold and flu symptoms. If you're dealing with nasal or sinus congestion and pressure, this product can help reduce swelling in your nasal passages, making it easier to breathe. It also addresses coughs caused by minor throat and bronchial irritation, which can be particularly helpful if you're trying to get a good night's sleep.

In addition to easing congestion, this medication can alleviate minor aches and pains, headaches, fever, sore throats, and the discomfort of a runny nose and sneezing. By promoting nasal and sinus drainage, it helps you feel more comfortable when you're under the weather.

Dosage and Administration

It's important to take this medication exactly as directed to ensure your safety. You should only use the dose cup that comes with the medication to measure your doses. Remember, you should not exceed 4 doses in a 24-hour period.

For adults and children aged 12 years and older, the recommended dose is 30 mL every 4 hours. If your child is between 6 and under 12 years old, they should take 15 mL every 4 hours. For children aged 4 to under 6 years, it's best to consult a doctor before giving them this medication. Please do not use this medication for children under 4 years old. Always follow these guidelines to avoid any potential overdose.

Overdose

If you suspect an overdose, it’s important to seek medical help immediately. You can contact a Poison Control Center at 1-800-222-1222 for guidance. Quick action is crucial for both adults and children, even if you don’t see any signs or symptoms of an overdose.

Remember, being aware of the situation and acting promptly can make a significant difference. Always prioritize safety and don’t hesitate to reach out for help if you think an overdose may have occurred.

Pregnancy Use

If you are pregnant or breastfeeding, it’s important to consult with a healthcare professional before using this medication. They can provide guidance on whether it’s safe for you and your baby. Always prioritize your health and the health of your child by seeking expert advice.

Lactation Use

If you are pregnant or breastfeeding, it’s important to consult with a healthcare professional before using any medication. This ensures that you understand any potential risks and can make informed decisions about your health and the health of your baby. Always prioritize open communication with your doctor regarding your breastfeeding journey.

Geriatric Use

When it comes to using this medication in older adults, there is no specific information available about dosage adjustments, safety concerns, or special precautions. This means that if you or a loved one is an older adult considering this medication, it’s important to consult with a healthcare provider. They can help determine the best approach based on individual health needs and any other medications being taken. Always prioritize open communication with your healthcare team to ensure safe and effective treatment.

Renal Impairment

If you have kidney problems, it's important to know that the drug insert does not provide specific information about dosage adjustments, special monitoring, or safety considerations for your condition. This means that there are no tailored guidelines for how this medication should be used if you have renal impairment (kidney issues).

Always consult your healthcare provider for personalized advice and to ensure that any medication you take is safe and appropriate for your health situation. They can help you understand how to manage your treatment effectively while considering your kidney health.

Hepatic Impairment

If you have liver problems, it's important to be cautious when using products that contain acetaminophen. Taking more than 4,000 mg in a 24-hour period can lead to severe liver damage for adults, while children should not take more than 5 doses in the same timeframe. Additionally, combining this product with other medications that also contain acetaminophen can increase the risk of liver damage. If you consume 3 or more alcoholic drinks daily, using this product may also pose a serious risk to your liver.

Before using this product, please consult your doctor if you have liver disease. They can provide guidance on safe usage and any necessary adjustments to your dosage. Your health and safety are the top priority, so don’t hesitate to seek professional advice.

Drug Interactions

It's important to be cautious when taking this medication, especially regarding potential interactions with other drugs. You should avoid using it alongside any other products that contain acetaminophen, which is a common pain reliever found in many over-the-counter and prescription medications. If you're unsure whether a medication contains acetaminophen, it's best to consult with your doctor or pharmacist.

Additionally, do not take this medication if you are currently using a monoamine oxidase inhibitor (MAOI), which is a type of drug used for certain mental health conditions, or for two weeks after stopping an MAOI. If you're on blood thinners like warfarin, or if you take sedatives or tranquilizers, make sure to discuss this with your healthcare provider before using this medication. Remember, combining alcohol with sedatives or tranquilizers can increase drowsiness, so it's wise to be cautious. Always talk to your healthcare provider about any medications or tests to ensure your safety.
