What Is Ibuprofen?

Developed during the 1960s, this medicine is used mainly to treat pain, inflammation and fever. It is classified as a non-steroidal anti-inflammatory drug that can be sold over the counter. It is so widely used and has been listed as essential medicine required by the healthcare system by the World Health Organisation (WHO). Ibuprofen has a simple yet effective method of inhibiting the production of an enzyme called prostaglandin around the area of injury. This enzyme is known to give the sensation of pain, and its reduction helps in pain alleviation.

How and When to Give Ibuprofen

Ibuprofen is ideally consumed along with or after food to avoid any digestive issues. How much one consumes depends on factors such as age and weight. As a result, adolescents, toddlers and infants are never given the same dosage.

The dosage and the timing of giving the medication will be provided by the doctor/pharmacist.

Consult the doctor

Who Can Take Ibuprofen?

If your child has a high fever but is responding well to home remedies that are alleviating the symptoms, Ibuprofen is not required. It is only when all other measures fail that you must turn to this, but it must be given only after a paediatrician has prescribed it.

Who Should Avoid Taking Ibuprofen?

Usually, a paediatrician will conduct a health checkup to diagnose the ailment and then prescribe ibuprofen. However, the doctor will also check for allergies and medical history to ensure the prescribed medicine does not have side effects. As a parent, you need to bear in mind that ibuprofen should be avoided for –

  • Children who suffer from diseases of the digestive tract such as ulcerative colitis or Crohn’s disease.
  • Children who have asthma.
  • Children who have allergic reactions to other medicines.
  • Children who have cardiovascular issues such as heart disease, blood pressure problems or irregular blood clotting.

Also, stick to the dosages and do not go overboard with the medicine. Below, we shall talk a little more about the effects of overdosage of ibuprofen.

What If a Child Takes Too Much Ibuprofen?

The British National Formulary says that children should never be given more than four doses of Ibuprofen in a day. Wait for half a day before giving them their next dosage. Some of the symptoms that indicate an overdose include:

  • Convulsions
  • Blurred Vision
  • Difficulty in breathing

In case these symptoms are displayed, you need to take your child to the hospital immediately. The doctor will give your child liquid charcoal to absorb the drug. Testing has shown that consuming over 636 mg per kilogram is fatal in animals. However, in humans, the case is different as in most cases, the subject becomes violently ill but does not die.

Sometimes, due to a busy schedule, parents may also forget to give a dosage. If that harmful for the child? Let’s find out.

What If You Forget to Give Your Child Ibuprofen?

Don’t panic if you have forgotten to give the medicine at the scheduled time. Give your child the medicine the moment you remember. If a lot of time has elapsed, and it is time for the next medicine, avoid giving two doses simultaneously. Simply give the amount that is due for that time frame to avoid an overdose.

Precautions to Take While Giving Ibuprofen to Your Child

  1. Read all the drug facts such as ingredients, expiration dates, dosage amount, and potential side-effects.
  2. Mixing of drugs with Ibuprofen can lead to death in certain cases. Always let your doctor know about any other medication that your child is having if the doctor recommends Ibuprofen.
  3. Make your child stand on a weighing scale before giving the Ibuprofen as the dosage is based on the weight of the child. Children are always growing, and an updated check on the weight can help you administer an accurate dose.
  4. Avoid prolonged usage of Ibuprofen as it can increase your child’s risk of developing heart disease.
  5. Make sure that your kids drink adequate water after taking the Ibuprofen tablet to avoid acidity.
  6. Keep the medicines away from the reach of children as some may find the taste nice.
  7. Make a note of the temperature of your child. Fever over 39-degree centigrade may require some medical intervention.
  8. Avoid giving them medicines in the dark as the dosage may become wrong.
  9. Avoid giving Ibuprofen for mild fever or cold as prolonged use can lead to complications such as digestive problems.


1. How Long Does It Take to Work?

Once consumed, it can take about 15-30 minutes for the medicine to get into action. It would take about 1 hour for your child to feel the effects of it.

2. Can You Give Ibuprofen With Prescription Medicines?

It does not mix well with other medicines and is usually a recipe for disaster. If your child is already on other medication, please mention it to your doctor if Ibuprofen is suggested.

3. What If a Child Vomits?

If a child vomits after ingestion of the medicine, see if there is any darkening of stool accompanied by stomach pain. If this is the case, it may be a case of stomach ulcer, and your child will have to be taken to a doctor. If it is exclusively vomiting, try giving the medicine along with food.

Ibuprofen is an emergency medicine that can be used to relieve the symptoms rather than doing any healing work. While there are a lot of benefits, parents are always cautioned to use the medicine as a last resort and only after a paediatrician has prescribed it. Sustained usage over time for even a mild fever can lead to issues like stomach ulcers and kidney stones.
