If you are administering this drug to a child, then ensure that it is specially formulated for children.

If you are taking the suspension form, then be sure to shake it well before using it. Note that not every liquid has to be shaken before use. That’s why you must read the instructions on the packaging. Measure the liquid using the recommended dose spoon/syringe/dropper. That way, you’ll get the right dose. Never use a tablespoon or household spoons.

Rapidly-dissolving tablets should be chewed or dissolved on the tongue, after which you can swallow with water. If it is a chewable tablet, then chew it thoroughly before you swallow.

Effervescent tablets should be dissolved in water, and then drunk.

The best time to use paracetamol and other pain medications is when you’ve noticed the first signs of pain. If you allow the symptoms to get worse, then the medication won’t work as well as it should.

 

How does paracetamol work?

How these drug works is not fully understood. However, it is believed to block the release of some chemicals in your brain that increases the sensation of pain.

 

Side effects of paracetamol

Paracetamol has side effects but they’re quite rare. Most people have a high tolerance to paracetamol. Allergic reactions occur in very rare cases. However, the most serious side effect of this drug is severe damage to the liver. Liver damage happens when you overdose on paracetamol.

Allergic reaction

  • People do develop an allergy to paracetamol, but it’s rare. Contact your GP without delay if you notice any of the following reactions after using the drug:
  • Hives
  • Difficulty swallowing or breathing
  • Severe itching
  • Swelling of the lips, face, tongue, or throat
  • Blistering or peeling skin

 

A person may have paracetamol poisoning if he or she takes too much of the drug. You see, when you take paracetamol, your liver will take it and process it into something different. If you take paracetamol in large amounts, then your liver will produce a larger amount of that substance. An excess of this substance will cause severe damage to your liver. On the other hand, if you take the recommended dosage of paracetamol, then you’re safe and not likely to suffer liver damage.

A person whose liver is damaged may experience the following symptoms:

  • Nausea or vomiting
  • Jaundice (yellowing of the whites of the eyes or the skin)
  • Fatigue
  • Excessive sweating

 

If you think you’ve overdosed on paracetamol, or you experience any of these symptoms, contact your GP at once or attended nearest emergency department.

 

Interactions with other medications

When two drugs interact, then one drug may change or affect how the other drug works. This is why you should not take any drug unless it is prescribed by your GP.

One drug that may interact with paracetamol is ketoconazole.

Ketoconazole interferes with some laboratory tests, thus there’s the chance of having a false result. Ensure that your healthcare provider and laboratory personnel know that you’re taking this drug.

 

Paracetamol may also interfere with:

  • Medications for tuberculosis
  • Epilepsy medications
  • Warfarin – a blood-thinning medication

 

Contraindications

Many people can take paracetamol without worrying about the side effects. Most people have a high tolerance to paracetamol. However, some groups may need to apply caution when taking the drug. These include:

People with a history of allergy to paracetamol

People with kidney or liver problems

People taking medicines for tuberculosis or epilepsy

Alcoholics

 

Takeaway

Paracetamol is a very effective and safe drug when taken at the right dosage. However, if you overdose on it, then you may experience severe or very deadly side effects. That’s why you must work together with your GP before taking this drug or any other medication.
