Your recommended dose of ibuprofen depends on your age.

For adults

The recommended dosage for adults is one or two 200-milligram (mg) tablets every 4 to 6 hours. Adults should not exceed 800 mg at once or 3,200 mg per day.

Adults over 60 years old should take as little ibuprofen as possible to manage their symptoms. Older adults have a higher risk of kidney and gastrointestinal side effects.

For children

To determine the safe dosage for children, you need to know the child’s weight and the formulation of ibuprofen you’re using.

Ibuprofen for children is available in:

Liquid measurements are given in milliliters (mL). Make sure to read the label and measure carefully.

  • tinnitus (ringing in the ears)
  • heartburn
  • nausea
  • vomiting
  • stomach pain

TIP

  1. Text “POISON” to 202-677-7600 to save the contact information for poison control to your smartphone.

If you can’t access a phone or computer, go to the nearest emergency room immediately. Do not wait until symptoms start. Some people who overdose on ibuprofen will not show symptoms right away.

At the hospital, doctors will monitor breathing, heart rate, and other vital signs. A doctor may insert a tube through the mouth to look for internal bleeding.

You may also receive the following treatments:

  • medications that make you throw up
  • decontamination of the stomach with activated charcoal
  • benzodiazepines to control seizures
  • breathing support, such as oxygen or a breathing machine (ventilator)
  • intravenous fluids
  • antihypertensive medications to reduce blood pressure

Children who consume more than 400 mg/kilogram (kg) of ibuprofen are at a higher risk of overdose and will likely require hospitalization. If they consume 100 mg/kg or less, they may be monitored at home.

An overdose of ibuprofen can cause severe problems in the gastrointestinal tract. These include:

Taking high doses of ibuprofen over long periods of time can also increase your risk of having a stroke or heart attack.

With prompt medical treatment, you’re likely to recover from an ibuprofen overdose. However, some people develop liver, kidney, or stomach issues. People with a prior history of ulcers or gastrointestinal bleeding should not take NSAIDS like ibuprofen.

Always read product labels carefully and take the smallest amount of ibuprofen possible that will help relieve your symptoms.

An adult should not take more than 3,200 mg of ibuprofen per day. A safe dose for children is much less than that. If you or someone you know has taken more than the recommended dose, call your local poison center or your local emergency services.

If you experience symptoms of an ulcer after taking ibuprofen, stop taking ibuprofen and call your doctor.
