What is Tylenol?

Below you can find some information about what Tylenol is:

  • Tylenol is a medication that contains acetaminophen (or paracetamol in other words) - a substance that is used worldwide to treat pain and fever.
  • The World Health Organization (WHO) recommends that paracetamol can be used to treat fevers in children only if their temperature is higher than 38.5 °C (101.3 °F).
  • This medication can also be used to relieve mild to moderate pain.
  • Paracetamol is particularly useful when nonsteroidal anti-inflammatory drugs, such as ibuprofen are contraindicated.

Baby Tylenol dosage - general rules

If you plan to use Tylenol in babies, here are some general rules you should follow:

  • Medications for children are formulated so they are safe for little ones. No matter what medicine and brand you are using, make sure that you are always following the instruction on the label and/or your doctor's advice.
  • Always use the dosing device that is provided with the product you bought.
  • Only one product with paracetamol should be used at a time.
  • Seek a professional doctor's advice to find the dosing for children who are less than 2 years old.
  • You should not give more than 5 doses of Tylenol a day.
  • In case of Tylenol overdose, seek medical assistance immediately.
