Drug Overview

Family Dollar Max Strength Dextromethorphan HBr, Guaifenesin is a maximum strength medication designed for adults to help relieve cough and chest congestion. It contains two active ingredients: dextromethorphan HBr, which acts as a cough suppressant to control your cough, and guaifenesin, an expectorant that thins and loosens mucus, making it easier to expel. This sugar-free formula also features a natural raspberry flavor and is suitable for individuals aged 12 and over.

This product is specifically formulated to provide relief from cough and chest congestion, making it a helpful option when you're feeling under the weather. It comes in a 4 FL OZ (118 mL) bottle and includes a dosage cup for your convenience.

Uses

If you're dealing with a cough caused by minor irritation in your throat or bronchial tubes, especially during a cold, this medication can provide temporary relief. It works by soothing your throat and helping to ease the discomfort associated with coughing.

Additionally, this medication helps to loosen phlegm (mucus) and thin out bronchial secretions, making it easier for your body to clear out mucus from your airways. This can be particularly helpful if you're feeling congested or have difficulty breathing due to mucus buildup.

Dosage and Administration

When using this medication, it's important to follow the dosing instructions carefully to ensure your safety and effectiveness. For adults and children aged 12 years and older, you should take 20 milliliters (mL) every 4 hours. However, make sure not to exceed 6 doses within a 24-hour period. To measure your dose accurately, always use the dosing cup that comes with the product, and keep it with the medication for easy access.

Please note that this product is not intended for children under 12 years of age, so if you have younger children, do not use this medication for them. Following these guidelines will help you use the medication safely and effectively.

What to Avoid

You should avoid using this product if you are currently taking a prescription monoamine oxidase inhibitor (MAOI), which are medications often prescribed for depression, psychiatric conditions, or Parkinson’s disease. Additionally, do not use this product for at least two weeks after stopping an MAOI. If you are unsure whether your prescription includes an MAOI, please consult your doctor or pharmacist before using this product.

It's important to follow these guidelines to prevent potential serious interactions and ensure your safety. Always prioritize open communication with your healthcare provider regarding any medications you are taking.

Side Effects

If you experience a cough that lasts more than 7 days, returns, or is accompanied by fever, rash, or a persistent headache, it's important to stop using the medication and consult a doctor, as these symptoms may indicate a serious condition. Additionally, if your cough is associated with excessive mucus or is chronic—such as those related to smoking, asthma, chronic bronchitis, or emphysema—you should also seek medical advice before using this medication.

Warnings and Precautions

If you are taking a prescription monoamine oxidase inhibitor (MAOI), which is a type of medication used for depression or certain other conditions, do not use this product. You should also wait at least two weeks after stopping an MAOI before using it. If you're unsure whether your medication contains an MAOI, please consult your doctor or pharmacist.

It's important to be aware of your health while using this product. If your cough lasts more than seven days, returns, or is accompanied by symptoms like fever, rash, or a persistent headache, stop using the product and contact your doctor. These could be signs of a more serious condition.

In case of an overdose, seek medical help immediately or contact a Poison Control Center at 1-800-222-1222. Your safety is a priority, so please take these precautions seriously.

If you notice any of these symptoms, or if you have concerns about a possible overdose, seek immediate medical help. You can contact your local emergency services or go to the nearest hospital. It's always better to be cautious and get professional assistance when it comes to medication safety.

Pregnancy Use

Renal Impairment

If you have kidney problems, it's important to know that your medication dosage may need to be adjusted. This is because your kidneys may not process the medication as effectively. Your healthcare provider will monitor your kidney function regularly, especially through tests that measure creatinine clearance (a way to assess how well your kidneys are filtering waste).

Before starting any new treatment, your renal function should be tested, and these tests should continue periodically. If you have moderate to severe renal impairment, a lower dose of the medication is usually recommended to ensure your safety and effectiveness of the treatment. Always discuss your kidney health with your doctor to ensure the best care.

Hepatic Impairment

If you have liver problems, it's important to know that your condition may affect how your body processes certain medications. This means you might need a lower dose of the drug to ensure it's safe and effective for you. Regular monitoring of your liver function tests (which check how well your liver is working) is also necessary to keep track of your health while using this medication.

When taking this drug, special precautions should be followed to minimize any risks associated with your liver condition. Always consult your healthcare provider for personalized advice and adjustments based on your specific situation.

Drug Interactions

It's important to be cautious when taking certain medications together. If you are currently using a prescription monoamine oxidase inhibitor (MAOI), or if you have stopped taking one within the last two weeks, you should avoid using this medication. Combining these can lead to serious interactions that may affect your health.

Always discuss any medications you are taking with your healthcare provider, including over-the-counter drugs and supplements. This ensures that you can safely manage your treatment and avoid any potential risks. Your health and safety are the top priority, so open communication with your provider is key.
