Dextromethorphan : Uses, Side Effects, Dosage, Precautions and More

Dextromethorphan is a common over-the-counter medication used to relieve coughs caused by colds, flu, and other respiratory conditions. As a cough suppressant, it works by affecting the signals in the brain that trigger the cough reflex. Here’s an in-depth look at dextromethorphan tablets, including their uses, side effects, dosage, precautions, and more.

Uses of Dextromethorphan Tablets

1. Cough Suppression: Dextromethorphan is primarily used to suppress a persistent cough. It is particularly effective for dry, unproductive coughs that don’t involve mucus.
2. Cold and Flu Relief: Often included in multi-symptom cold and flu medications, dextromethorphan helps to alleviate one of the most annoying symptoms of these illnesses.
3. Chronic Cough Management: For some individuals with chronic coughs not related to an underlying severe condition, dextromethorphan can provide relief.

How Dextromethorphan Works

Dextromethorphan acts on the cough center in the brain to reduce the urge to cough. Unlike some other cough suppressants, it does not have significant pain-relieving effects, nor does it treat the underlying cause of the cough.

Dosage of Dextromethorphan Tablets

The dosage of dextromethorphan varies based on the product and the individual’s age:

• Adults and children 12 years and older: The typical dose is 10-20 mg every 4 hours or 30 mg every 6-8 hours, with a maximum of 120 mg in 24 hours.
• Children 6-12 years: The usual dose is 5-10 mg every 4 hours or 15 mg every 6-8 hours, with a maximum of 60 mg in 24 hours.
• Children 2-6 years: The recommended dose is 2.5-5 mg every 4 hours or 7.5 mg every 6-8 hours, with a maximum of 30 mg in 24 hours.

It’s important to follow the specific instructions on the medication label or as prescribed by a healthcare provider.

Side Effects of Dextromethorphan Tablets

While dextromethorphan is generally well-tolerated, it can cause side effects in some individuals. Common side effects include:

1. Dizziness: Feeling lightheaded or unsteady is a common side effect.
2. Drowsiness: Some people may feel sleepy after taking dextromethorphan.
3. Nausea and Vomiting: Gastrointestinal discomfort can occur.
4. Stomach Pain: Some users report stomach cramps or pain.
5. Nervousness or Restlessness: Feeling anxious or jittery can be a side effect, especially at higher doses.

Serious Side Effects and Overdose

Although rare, serious side effects can occur, particularly with excessive use or overdose. These include:

• Confusion: Severe disorientation or confusion may indicate an overdose.
• Hallucinations: Seeing or hearing things that are not there can occur with high doses.
• Slow or Shallow Breathing: Respiratory depression is a severe side effect requiring immediate medical attention.
• Severe Drowsiness or Dizziness: Extreme drowsiness can impair daily activities and increase the risk of accidents.

Precautions and Warnings

1. Drug Interactions: Dextromethorphan can interact with other medications, especially monoamine oxidase inhibitors (MAOIs) used to treat depression. Combining these drugs can cause a dangerous increase in serotonin levels, leading to serotonin syndrome.
2. Medical Conditions: Individuals with certain medical conditions, such as asthma, chronic bronchitis, or emphysema, should consult a healthcare provider before using dextromethorphan.
3. Pregnancy and Breastfeeding: Pregnant or breastfeeding women should seek medical advice before using this medication to ensure it’s safe for them and their baby.
4. Alcohol: Avoid consuming alcohol while taking dextromethorphan, as it can increase the risk of side effects like drowsiness and dizziness.
5. Abuse Potential: Dextromethorphan has the potential for abuse, particularly among teenagers. High doses can produce euphoric and hallucinogenic effects. Awareness and proper storage of the medication are essential to prevent misuse.

How to Take Dextromethorphan Tablets

• Read the Label: Always read and follow the instructions on the medication label.
• Measure Carefully: Use a proper measuring device if taking a liquid form to ensure the correct dose.
• Do Not Exceed the Recommended Dose: Taking more than the recommended dose can increase the risk of side effects and overdose.
• Stay Hydrated: Drink plenty of fluids to help loosen mucus and keep your throat moist.

Storage and Disposal

• Storage: Keep dextromethorphan tablets in a cool, dry place away from direct light and moisture. Store out of reach of children and pets.
• Disposal: Dispose of unused or expired medication properly. Do not flush medications down the toilet unless instructed. Many pharmacies offer take-back programs for safe disposal.

When to See a Doctor

• Persistent Symptoms: If your cough persists for more than a week, comes back, or is accompanied by a fever, rash, or persistent headache, seek medical advice.
• Side Effects: If you experience severe side effects or signs of an allergic reaction (such as rash, itching, swelling, severe dizziness, or trouble breathing), get medical help immediately.
• Underlying Conditions: If you have a chronic respiratory condition or other underlying health issues, consult your healthcare provider before using dextromethorphan.
