Version July 2025
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use. Ibuprofen/famotidine is contraindicated during the perioperative setting of coronary artery bypass graft (CABG) surgery.
NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events.
Note: Safety: Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
Osteoarthritis, rheumatoid arthritis: Oral: One tablet (ibuprofen 800 mg/famotidine 26.6 mg) 3 times daily.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
CrCl ≥50 mL/minute: There are no dosage adjustments provided in the manufacturer's labeling.
CrCl <50 mL/minute: Use not recommended; avoid use in patients with advanced renal disease.
There are no dosage adjustments provided in the manufacturer's labeling (has not been studied).
Refer to adult dosing. Unless alternative agents are ineffective, avoid short-term scheduled use in combination with corticosteroids, anticoagulants, or antiplatelet agents or chronic use with or without medications that increase risk for bleeding (Ref).

Hypersensitivity (eg, anaphylactic reactions, serious skin reactions) to ibuprofen, famotidine, or any component of the formulation or to other H2-receptor antagonists; history of asthma, urticaria, or allergic-type reaction to aspirin or other NSAIDs; use in the setting of coronary artery bypass graft (CABG) surgery
Concerns related to adverse effects:
• Anaphylactoid reactions: Even in patients without prior exposure anaphylactoid reactions may occur; patients with "aspirin triad" (bronchial asthma, aspirin intolerance, rhinitis) may be at increased risk. Contraindicated in patients who experience bronchospasm, asthma, rhinitis, or urticaria with nonsteroidal anti-inflammatory drug (NSAID) or aspirin therapy.
• Cardiovascular events: Relative risk appears to be similar in those with and without known cardiovascular disease or risk factors for cardiovascular disease; however, absolute incidence of serious cardiovascular thrombotic events (which may occur early during treatment) was higher in patients with known cardiovascular disease or risk factors, and in those receiving higher doses. New-onset hypertension or exacerbation of hypertension may occur (NSAIDs may also impair response to ACE inhibitors, thiazide diuretics, or loop diuretics); may contribute to cardiovascular events; monitor blood pressure; use with caution in patients with hypertension. May cause sodium and fluid retention, use with caution in patients with edema. Avoid use in heart failure (FDA 2015). Avoid use in patients with a recent MI unless benefits outweigh risk of cardiovascular thrombotic events. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of cardiovascular events; alternate therapies should be considered for patients at high risk.
• CNS effects: May cause drowsiness, dizziness, blurred vision, and other neurologic effects which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving). Confusion, delirium, seizures, and coma have been linked to famotidine use. Increased age (>50 years) and renal or hepatic impairment are thought to be associated.
• Drug reaction with eosinophilia and systemic symptoms: Potentially serious, sometimes fatal, drug reaction with eosinophilia and systemic symptoms (DRESS), also known as multiorgan hypersensitivity reactions, has been reported with NSAIDs. Monitor for signs and symptoms (eg, fever, rash, lymphadenopathy, eosinophilia) in association with other organ system involvement (eg, hepatitis, nephritis, hematological abnormalities, myocarditis, myositis). Early symptoms of hypersensitivity reaction (eg, lymphadenopathy, fever) may occur without rash; discontinue therapy and further evaluate if DRESS is suspected.
• ECG changes: Prolonged QT interval has been reported in patients with moderate to severe kidney impairment. The FDA has received reports of torsade de pointes occurring with famotidine (Poluzzi 2009).
• GI events:Avoid use in patients with active GI bleeding. In patients with a history of acute lower GI bleeding, avoid use of non-aspirin NSAIDs, especially if due to angioectasia or diverticulosis (Strate 2016). Use caution with a history of GI ulcers, concurrent therapy known to increase the risk of GI bleeding (eg, aspirin, anticoagulants, and/or corticosteroids, selective serotonin reuptake inhibitors), advanced hepatic disease, coagulopathy, smoking, use of ethanol, or in elderly or debilitated patients. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of GI adverse events; alternate therapies should be considered for patients at high risk.
• Hematologic effects: Platelet adhesion and aggregation may be decreased; may prolong bleeding time; patients with coagulation disorders or who are receiving anticoagulants should be monitored closely. Anemia may occur; patients on long-term NSAID therapy should be monitored for anemia. Rarely, NSAID use has been associated with potentially severe blood dyscrasias (eg, agranulocytosis, thrombocytopenia, aplastic anemia).
• Hepatic effects: Transaminase elevations have been reported with NSAID use; closely monitor patients with any abnormal LFT. Rare (sometimes fatal) severe hepatic reactions (eg, fulminant hepatitis, hepatic necrosis, hepatic failure) have occurred with NSAID use; discontinue immediately if signs or symptoms of hepatic disease develop or if systemic manifestations occur.
• Hyperkalemia: NSAID use may increase the risk of hyperkalemia, particularly in the elderly, diabetics, renal disease, and with concomitant use of other agents capable of inducing hyperkalemia (eg, ACE-inhibitors). Monitor potassium closely.
• Ophthalmic effects: Blurred/diminished vision, scotomata, and/or changes in color vision have been reported. Discontinue therapy and refer for ophthalmologic evaluation if symptoms occur.
• Renal effects: NSAID use may compromise existing renal function; dose-dependent decreases in prostaglandin synthesis may result from NSAID use, reducing renal blood flow which may cause renal decompensation (usually reversible). Patients with impaired renal function, dehydration, hypovolemia, heart failure, hepatic impairment, those taking diuretics, and ACE inhibitors, and the elderly are at greater risk of renal toxicity. Rehydrate patient before starting therapy; monitor renal function closely. Long-term NSAID use may result in renal papillary necrosis and other renal injury.
• Skin reactions: NSAIDs may cause serious skin adverse events (sometimes fatal), including exfoliative dermatitis, fixed drug eruption (including generalized bullous fixed drug eruption), Stevens-Johnson syndrome, and toxic epidermal necrolysis; may occur without warning; discontinue use at first sign of skin rash (or any other hypersensitivity).
• Vitamin B12 deficiency: Prolonged treatment (≥2 years) may lead to vitamin B12 malabsorption and subsequent vitamin B12 deficiency. The magnitude of the deficiency is dose-related and the association is stronger in females and those younger in age (<30 years); prevalence is decreased after discontinuation of therapy (Lam 2013).
Disease-related concerns:
• Aseptic meningitis: May increase the risk of aseptic meningitis, especially in patients with systemic lupus erythematosus (SLE) and mixed connective tissue disorders.
• Asthma: Contraindicated in patients with aspirin-sensitive asthma; severe and potentially fatal bronchospasm may occur. Use caution in patients with other forms of asthma.
• Bariatric surgery: Gastric ulceration: Avoid chronic use of oral nonselective NSAIDs after bariatric surgery; development of anastomotic ulcerations/perforations may occur (Bhangu 2014; Mechanick 2020). Short-term use of celecoxib or IV ketorolac is recommended as part of a multimodal pain management strategy for postoperative pain (Chou 2016; Horsley 2019; Thorell 2016).
• Coronary artery bypass graft surgery: Risk of MI and stroke may be increased with use following coronary artery bypass graft surgery.
• Gastric malignancy: Relief of symptoms does not preclude the presence of a gastric malignancy.
• Hepatic impairment: Use with caution in patients with hepatic impairment; patients with advanced hepatic disease are at an increased risk of GI bleeding with NSAIDs.
• Renal impairment: Avoid use in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal failure. Famotidine CNS adverse effects (eg, seizures, delirium, coma) may be increased in patients with renal impairment (CrCl <50 mL/minute); use is not recommended in these patients since product contains a fixed amount of famotidine and dose cannot be adjusted.
Concurrent drug therapy issues:
• Clopidogrel: Proton pump inhibitors (PPIs) may diminish the therapeutic effect of clopidogrel thought to be due to reduced formation of the active metabolite of clopidogrel. The manufacturer of clopidogrel recommends either avoidance of both omeprazole (even when scheduled 12 hours apart) and esomeprazole or use of a PPI with comparatively less effect on the active metabolite of clopidogrel (eg, pantoprazole). In contrast to these warnings, others have recommended the continued use of PPIs, regardless of the degree of inhibition, in patients with a history of GI bleeding or multiple risk factors for GI bleeding who are also receiving clopidogrel since no evidence has established clinically meaningful differences in outcome; however, a clinically significant interaction cannot be excluded in those who are poor metabolizers of clopidogrel (Abraham 2010; Levine 2011).
Special populations:
• Older adult: Older adult patients are at increased risk for serious GI, cardiovascular, and/or renal adverse events; use with caution.
Other warnings/precautions:
• Surgical/dental procedures: Withhold products containing ibuprofen for at least 4 to 6 half-lives prior to surgical or dental procedures.
