Health Conditions Discover Plan Connect. Is It Possible to Overdose on Ibuprofen? Medically reviewed by Alan Carter, Pharm. They may contain ingredients similar to ibuprofen such as aspirin, ibuprofen, ketoprofen, or naproxen. If you also take aspirin to prevent stroke or heart attack, taking ibuprofen can make aspirin less effective in protecting your heart and blood vessels.
If you take both medicines, take ibuprofen at least 8 hours before or 30 minutes after you take aspirin non-enteric coated form. Use Ibuprofen Advil exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Use exactly as directed on the label, or as prescribed by your doctor. Use the lowest dose that is effective in treating your condition.
An ibuprofen overdose can damage your stomach or intestines. The maximum amount of ibuprofen for adults is milligrams per dose or mg per day 4 maximum doses. A child's dose of ibuprofen is based on the age and weight of the child. Carefully follow the dosing instructions provided with children's ibuprofen for the age and weight of your child.
Ask a doctor or pharmacist if you have questions. Shake the oral suspension liquid before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device not a kitchen spoon.
Store at room temperature away from moisture and heat. Do not allow the liquid medicine to freeze. Since ibuprofen is used when needed, you may not be on a dosing schedule.
Skip any missed dose if it's almost time for your next dose. Do not use two doses at one time. Ibuprofen is generally safe to use for several years, but taking it for a long time or in high doses can increase your risk for stomach bleeding or ulcers.
If you take this medicine for years, you may also be at an increased risk for heart attack or stroke. A typical dosage for adults who have minor aches and pains might be milligrams mg to mg of OTC ibuprofen every four to six hours.
The toxicity of ibuprofen following self-poisoning has been reported in five large case series [ 3 - 5 , 10 , 14 ]. Histories in patients presenting with an overdose have been shown to be unreliable [ 16 ], however, so to try and predict those patients who are at risk of severe ibuprofen-induced toxicity, a nomogram based on the time since ingestion and the serum ibuprofen concentration, similar to that used for paracetamol acetaminophen , has been developed [ 4 ].
Subsequent studies have shown conflicting results as to whether this nomogram is accurate [ 5 ] or inaccurate [ 10 ] at predicting those at risk of severe toxicity. Since ibuprofen concentrations are not routinely available in most emergency departments or hospitals, there are concerns about the accuracy of the nomogram, the toxic effects of ibuprofen are predictable and unlike paracetamol poisoning there is no effective antidote, we would not recommend use of the ibuprofen nomogram in routine clinical practice.
Management of patients presenting following deliberate self-poisoning with ibuprofen consists of gut decontamination with activated charcoal, if they present within one hour of a potentially toxic overdose, and generalised supportive care [ 17 , 18 ]. As already discussed, multidose activated charcoal may be appropriate in patients who have ingested a potentially toxic amount of a sustained-release preparation. Other more severe features of ibuprofen toxicity should be managed appropriately.
Ibuprofen-induced seizures that are nonself-limiting should initially be managed with intravenous diazepam 0. For resistant metabolic acidosis that is not responding, then haemofiltration with a nonlactate bicarbonate buffer may be beneficial.
Although ibuprofen has a relatively low volume of distribution 0. Previous studies have demonstrated no accumulation of ibuprofen in patients with renal impairment [ 20 ] and, in functionally anephric patients undergoing renal replacement therapy with haemodialysis, no accumulation of ibuprofen was seen and there was no detectable ibuprofen in the dialysate, indicating that the ibuprofen was eliminated through metabolism [ 21 ].
This provides further support that extracorporeal treatments will probably not be beneficial in increasing the clearance of ibuprofen in overdose, and there have been no previous reported cases of their attempted use in patients with ibuprofen toxicity. There have been no published studies on the routine prophylactic use of H 2 histamine receptor antagonists or proton pump inhibitors in trying to reduce the risk of ibuprofen or other NSAID-related gastrointestinal toxicity.
There have been nine reported cases of fatality following ibuprofen self-poisoning in the literature to date, although other factors probably contributed to death in eight of these cases [ 3 - 11 ]. The co-ingestion of other drugs at the time of the overdose, such as aspirin, paracetamol, theophylline and cyclobenzaprine, contributed to death in four cases [ 3 , 6 , 7 , 9 ]. Aspiration pneumonia that developed as a complication of ibuprofen-induced apnoeic episodes [ 4 ] and septic shock, thought to be unrelated to ibuprofen toxicity [ 10 ], contributed to two deaths.
Refusal of treatment of ibuprofen-induced oliguric renal failure and sepsis, felt by the authors to be survivable, significantly contributed to one death [ 5 ]. The circumstances surrounding one death are unclear as the patient was found dead near their home [ 8 ]. There are limited details of and no confirmatory ibuprofen concentrations for the final death, which has been reported in abstract form only [ 11 ]. Ibuprofen concentrations have been measured in four of the previous fatalities [ 6 , 8 - 10 ].
The main differences between our reported case and the other two cases with previous reported post mortem ibuprofen concentrations is that our case had higher peripheral blood and lower liver extract concentrations. Since the exact timing of ingestion was not known in our case and was not reported in the other two cases, the differences in peripheral blood and liver extract ibuprofen concentrations may be due to differences in distribution and metabolism.
It is therefore probable, given the post mortem ibuprofen concentrations in our reported case, that our patient died sooner after ingestion than the other two reported cases, as peripheral blood concentrations had not had sufficient time to fall and the liver had not started to metabolise as much ibuprofen. The other unknown factor in all of these cases is the impact of impaired haemodynamics, renal dysfunction and metabolic acidosis on ibuprofen kinetics.
We have described the case of a fatality following severe poisoning with sustained-release ibuprofen. The patient presented with a reduced Glasgow Coma Scale, severe metabolic acidosis and haemodynamic compromise that did not respond to meticulous supportive care, to treatment with sodium bicarbonate, to haemofiltration and to inotropic support. There were no other toxicological or medical causes for the patient's clinical presentation.
Multidose activated charcoal was utilised in this patient due to the ingestion of a sustained-release preparation, and its use was supported by elevated ibuprofen concentrations in the gastric contents following death.

Abstract Introduction Ibuprofen is a nonsteroidal anti-inflammatory drug available over the counter and on prescription for the management of pain and inflammation. Case report A year-old female presented after deliberate ingestion of up to g sustained-release ibuprofen, with a reduced level of consciousness, severe metabolic acidosis and haemodynamic compromise.
Discussion Most patients with ibuprofen poisoning are either asymptomatic or have mild gastrointestinal symptoms; severe poisoning with ibuprofen is rare. Introduction Ibuprofen is a nonsteroidal anti-inflammatory drug NSAID commonly used as an analgesic, as an anti-inflammatory agent and as an anti-pyretic agent [ 1 , 2 ]. Case report A year-old woman with no significant past medical history presented after ingestion of up to tablets of mg sustained-release ibuprofen, equivalent to approximately g.

Open in a separate window. Results Serum toxicology screening Samples of ante mortem serum were obtained following admission and were analysed for ibuprofen by the Medical Toxicology Laboratory in London.
Post mortem The cause of death was probably directly related to the ibuprofen overdose, since there was no evidence of another cause of death at the post mortem examination.
