Let's learn exactly about this medicine for colds and coughs! (Acetaminophen; Chlorpheniramine; Dextromethorphan)

When we get a cold, or when we have a cough with a fever and a feeling of weakness, it's very annoying, isn't it? So what we quickly do is go to a pharmacy and ask for a single medicine pill that will cure all these symptoms. Several types of medicine are combined in one pill like this. So today we are talking about one of the most commonly used combinations of medicines.

What exactly is this medicine?

Simply put, it's a combination of three medications. It's used to control the symptoms of a cold , allergies, or the flu. Let's take a look at what these three are and what they do.

1. Acetaminophen : Although this name may sound unfamiliar, we all know this drug. It is also the same as Paracetamol , which we usually take for fever, body aches, and headaches. So what this does is reduce pain and fever.

2. Chlorpheniramine : This is an antihistamine . It is used to control allergy symptoms such as runny nose , stuffy nose , itchy eyes, and sneezing .

3. Dextromethorphan: This is a cough suppressant . It helps to stop a dry cough, especially one that does not produce mucus.

This means that this one pill will provide immediate relief from several of your symptoms, including fever, body aches, runny nose, and cough.

Things you need to tell your doctor before taking this medicine

Although you can buy this medicine at the pharmacy, if you have any health conditions, you should definitely talk to your doctor before using it, as this medicine is not suitable for everyone.

If you have these conditions... Why is it important to inform the doctor?
Liver disease or frequent alcohol consumption Acetaminophen, which is contained in this medicine, can affect the liver. If you already have liver problems, they may become worse.
Lung or respiratory disease (e.g., asthma, COPD) This medication can sometimes affect breathing, so people with these conditions should be careful.
Glaucoma condition The chlorpheniramine contained in the medicine may increase eye pressure.
Difficulty urinating (e.g., enlarged prostate) This medicine may make it more difficult to urinate.
If you have taken an MAOI medication (e.g. Marplan, Nardil) within the past 14 days It is absolutely forbidden to take these two medications together as this can cause a very dangerous reaction.
If you are pregnant or trying to get pregnant It is essential to seek medical advice before taking any medication during pregnancy.
If you are a breastfeeding mother The ingredients in the medicine can pass to the baby through breast milk, so it's best to ask your doctor.

How should I use the medicine?

Take this medicine with a glass of water. Follow the instructions on the medicine label or packet exactly. Do not take more than the recommended dose. If you experience stomach upset, take it after a meal.

  • If given to children: Although this medicine is sometimes given to children over 12 years of age, do not give it without consulting a doctor.
  • Elderly: People over the age of 65 may experience a slightly stronger effect from this medication. Therefore, a lower dose may be prescribed.

What if I drink too much by mistake?

If you think you have taken more medicine than you think, don't delay. Don't wait until symptoms appear. Go to the nearest hospital Emergency Department (ETU) immediately. Or call the National Poisons Information Center at the Colombo National Hospital . Acetaminophen overdose can cause severe liver damage.

This medicine is for you only. Do not give it to anyone else just because they have the same symptoms as you.

Other things that are incompatible with this medicine (Interactions)

If you are taking other medications, you should tell your doctor about them before taking this medicine, as some medications can cause adverse effects when taken together.

Especially do not take this medicine with the following:

  • MAOI type medications: (e.g., antidepressants such as Marplan, Nardil, Parnate).
  • Alcohol: Taking this medication with alcohol can increase drowsiness and dizziness. It also increases the risk of liver damage.
  • Other medications that cause drowsiness: Taking this with sleeping pills, tranquilizers (e.g., Diazepam, Lorazepam), some allergy medications (other antihistamines), and strong painkillers (opioids) can cause excessive drowsiness.
  • Warfarin: This medication, which is used to prevent blood clots, can interact with acetaminophen if you are taking it.

This list is not complete, so tell your doctor about every medication, vitamin, or traditional medicine you take.

Be careful of these things when taking medication!

  • Check for symptoms: If you have a fever for more than 3 days, or if your symptoms do not improve or worsen after taking medication for 7 days, be sure to see a doctor.
  • Special attention to acetaminophen: This is the most important thing.While you are taking this medicine, do not take any other medicine that contains acetaminophen (or paracetamol). Many over-the-counter cold and flu medicines contain this. Read the label carefully before taking any medicine. If in doubt, ask a doctor.
  • Drowsiness: This medicine may make you feel drowsy and dizzy . Therefore, do not drive or operate machinery while taking this medicine.
  • Severe skin reactions: Very rarely, this medicine may cause a severe skin reaction. If you experience fever, body aches, and a red rash, blistering, or peeling skin, seek immediate medical attention.
