Let's learn exactly about cold and allergy medications (Acetaminophen; Chlorpheniramine)

Do you also often get colds and have a runny nose ? Or are you tired of itching and sneezing due to a sudden allergy ? Today we are going to talk about a medicine that many of us buy from a pharmacy and use at times like these. Let's talk clearly about what exactly this medicine is, what it does, and what things to be careful about when using it.

What does this medicine contain?

Simply put, this is a combination of two types of medicine.

When these two are combined, they provide relief from a multitude of symptoms caused by colds, flu, and allergies.

Things you need to tell your doctor before taking this medicine

Before using this medicine, it is imperative that you inform your doctor if you have any of the following health conditions:

Your situation Why is awareness important?
If you are a frequent drinker The combination of alcohol and acetaminophen (paracetamol) can cause severe liver damage.
Liver disease The acetaminophen in this medicine is eliminated from the body through the liver. If you have liver disease, it can be made worse.
Glaucoma condition Chlorpheniramine can increase eye pressure, which is not good for glaucoma.
Breathing difficulties (such as asthma, COPD) This medicine can thicken the secretions in the respiratory tract, which may increase breathing difficulties.
Difficulty urinating This medication may increase difficulty urinating, especially in conditions such as prostate enlargement.
Allergies to other medications and foods Please let us know if you have had any previous allergies to these medications or anything else.
If you are pregnant or trying to get pregnant It is very important 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 ask your doctor.

How do you use this medicine?

The medicine should be used exactly as directed on the label.

  • Swallow this pill with a glass of water.
  • You can take it before or after a meal, but if you feel like you're having an upset stomach, it's best to take it with a meal.
  • Never take more than the prescribed dose.

Special information about children and adults

  • Children: This medicine is sometimes recommended for children over 6 years of age, but only on the advice of a doctor. You need to be very careful about the dosage when giving it to children.
  • People over 65: Older people may be more sensitive to the effects of this drug, especially drowsiness, so they are usually prescribed a lower dose.

Overdosage - Very important!

If you think you have taken too much of this medicine, call the National Poisons Information Centre at the National Hospital immediately, even if you have no symptoms. Or go to the Emergency Department (ETU) of the nearest hospital. Taking too much acetaminophen can cause serious liver damage.

Other things that may interact with this medicine

Other medications you are taking may interact with this medicine, so tell your doctor about all the medications you are taking (including vitamins and herbal products).

Especially avoid taking this medicine with the following:

  • MAOI medications: Do not take this with antidepressants such as Marplan, Nardil, or Parnate for any reason .
  • Alcohol: Increases drowsiness and dizziness. Damage to the liver is also very high.
  • Other medications that cause drowsiness or intoxication: sleeping pills, tranquilizers (e.g. Diazepam, Alprazolam), painkillers (Opioids), muscle relaxants.
  • Other antihistamines: These may also be contained in other cough, cold, and allergy medications.
  • Warfarin: This medicine, which is used to prevent blood clots, may affect the effectiveness of this medicine.

This list is not complete, so it is very important to inform your doctor about any medications you are taking.

Things to keep in mind when taking medication

  • Watch for symptoms: Tell your doctor if your symptoms do not improve or if they get worse. If you have a fever for more than 3 days, or if you need to use this medicine for more than 10 days (more than 5 days for children), seek medical advice.
  • Be careful with acetaminophen: When taking this medicine, do not take any other medicine that contains acetaminophen (e.g. Panadol, Calpol). Doing so may increase the dose and cause liver damage. Always read the label of the medicine.
  • Drowsiness and dizziness: You may feel drowsy and dizzy after taking this medicine. Therefore, avoid driving or operating machinery while taking this medicine. Drinking alcohol can make this condition worse.
  • Severe skin allergy: Very rarely, some people may develop a severe skin allergy. Seek immediate medical attention if you have fever, body aches, red or purple spots on your skin that blister and look like your skin is peeling, or if you have swollen lymph nodes in your face, lips, neck, or armpits .
  • Dry mouth: If your mouth is dry, chew sugar-free gum and drink more water. If this persists, tell your doctor.
