Taking too much ibuprofen can result in an overdose. This can cause dangerous side effects such as damage to your stomach or intestines. In rare cases, an overdose can be fatal.
For this reason, you should always take it exactly as directed on the label or as recommended by your doctor.
If you think that you or someone you know has overdosed on ibuprofen, contact your local poison center or your local emergency services. In the United States, you can reach the poison center by calling 1-800-222-1222.

Certain medications can increase your risk of having an overdose of ibuprofen.
- Selective serotonin reuptake inhibitors (SSRIs), which can interfere with the metabolism of NSAIDs while also increasing pain and bleeding
- antihypertensives, which are medications for high blood pressure that may increase the risk of kidney damage
- aspirin, which may increase the risk of serious side effects
- diuretics (water pills), which increase the risk of kidney failure when combined with ibuprofen
- lithium, which increases the risk of toxicity
- methotrexate, which increases the risk of toxicity
- anticoagulants (blood thinners), such as warfarin, because they can increase your risk of serious gastrointestinal bleeding
Mixing ibuprofen with alcohol can also increase your risk of having serious side effects, like stomach or intestinal bleeding.
Not everyone will experience symptoms of an ibuprofen overdose right away. Some people won’t have any visible symptoms at all.
If you do experience symptoms of an ibuprofen overdose, they’re usually mild. Mild symptoms may
- tinnitus (ringing in the ears)
- stomach pain
- blurred vision
Severe symptoms can include:
- difficult or slow breathing
- hypotension (low blood pressure)
- little to no urine production
- severe headache
If you or someone you know has taken more than the maximum recommended dose of ibuprofen, contact your local poison center. In the United States, you can reach the poison center by calling 1-800-222-1222. You can call this number 24 hours a day. Stay on the line for further instructions.
If possible, have the following information ready:

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)

An overdose of ibuprofen can cause severe problems in the gastrointestinal tract. These include:
- stomach or intestinal perforation, which can be fatal
- liver or kidney failure
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.
