Drug Overview

Robitussin MAXIMUM STRENGTH Nighttime Cough DM is a medication designed to help relieve cough and allergy symptoms. It contains two active ingredients: dextromethorphan HBr, which is a cough suppressant that helps control the urge to cough, and doxylamine succinate, an antihistamine that alleviates symptoms such as a runny nose, sneezing, and itchy, watery eyes.

This product is intended for individuals aged 12 and over and is particularly useful for providing fast relief from coughs caused by minor throat and bronchial irritation, often associated with colds, as well as symptoms from hay fever or other upper respiratory allergies. By addressing these symptoms, it can help you get a better night's sleep.

Uses

You can use this medication to temporarily relieve a cough caused by minor irritation in your throat and bronchial tubes, which often happens when you have a cold. It also helps ease symptoms associated with hay fever or other upper respiratory allergies, such as a runny nose, sneezing, itchy or watery eyes, and itching in your nose or throat.

Additionally, this medication can help control your urge to cough, making it easier for you to get a good night's sleep.

Dosage and Administration

To take this medication safely, make sure to use the dosing cup that comes with the product to measure your dose accurately. It's important to keep this dosing cup with the medication so you always have it on hand. For adults and children aged 12 years and older, the recommended dose is 20 milliliters (mL) every 6 hours. However, you should not take more than 4 doses within a 24-hour period.

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. Always follow these guidelines to ensure safe and effective use.

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, psychiatric conditions, or Parkinson's disease. Additionally, do 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 important to follow these guidelines: do not use this product to sedate a child or to make them sleepy, and do not exceed the recommended dosage. Also, avoid consuming alcoholic drinks, as alcohol, along with sedatives and tranquilizers, can increase drowsiness.

Side Effects

You should be aware that using this product can lead to marked drowsiness, so it's important to avoid alcohol and other sedatives, as they may increase this effect. Be cautious when driving or operating machinery. In some cases, especially in children, excitability may occur.

If your cough lasts more than 7 days, returns, or is accompanied by fever, rash, or a persistent headache, stop using the product and consult a doctor, as these could indicate a more serious condition. Additionally, if you have certain health issues like trouble urinating due to an enlarged prostate, glaucoma, or chronic breathing problems, it's best to talk to your doctor before using this product. Always seek medical help immediately in case of an overdose.

Warnings and Precautions

You should not use this medication to sedate a child or make them sleepy. Additionally, avoid using it if you are currently taking a prescription monoamine oxidase inhibitor (MAOI) for depression, psychiatric conditions, or Parkinson's disease, or if you have stopped taking an MAOI within the last two weeks.

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 may affect you if your kidneys are not functioning properly.

Always consult your healthcare provider for personalized advice and to ensure that any medication you take is safe and appropriate for your kidney health. They can help monitor your condition and make any necessary adjustments to your treatment plan.

Combining these can lead to serious interactions that could affect your health.
