Osteoarthritis, rheumatoid arthritis: Relief of signs and symptoms of osteoarthritis and rheumatoid arthritis (RA) and to decrease the risk of developing upper GI ulcers
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
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 in the setting of coronary artery bypass graft (CABG) surgery.
Serious gastrointestinal bleeding, ulceration, and perforationNSAIDs 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.

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 NSAID or aspirin therapy.
- Cardiovascular events: [US Boxed Warning]: NSAIDs cause an increased risk of serious (and potentially fatal) adverse cardiovascular thrombotic events, including MI and stroke.Risk may occur early during treatment and may increase with duration of use. 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 (ACCF/AHA [Yancy 2013]). 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.
- ECG changes: Prolonged QT interval has been reported in patients with renal dysfunction. The FDA has received reports of torsade de pointes occurring with famotidine (Poluzzi 2009).
- Gastrointestinal events: [US Boxed Warning]: NSAIDs cause increased risk of serious gastrointestinal inflammation, ulceration, bleeding, and perforation (may be fatal); elderly patients and patients with history of peptic ulcer disease and/or GI bleeding are at greater risk of serious GI events.These events can be fatal and may occur at any time during therapy and without warning. Avoid use in patients with active GI bleeding. 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 potentially fatal serious skin adverse events including exfoliative dermatitis, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN); 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.
- Coronary artery bypass graft surgery: [US Boxed Warning]: Use is contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Risk of MI and stroke may be increased with use following CABG 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).
- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
Special populations:
- Elderly: Elderly 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.
Animal reproduction studies have not been conducted with this combination. Avoid use of ibuprofen/famotidine in pregnant women starting at 30 weeks of gestation (third trimester) due to the risk of premature closure of the fetal ductus arteriosus. Refer to individual agents.
Ibuprofen: Reversibly inhibits cyclooxygenase-1 and 2 (COX-1 and 2) enzymes, which results in in decreased formation of prostaglandin precursors; has antipyretic, analgesic, and anti-inflammatory properties
Famotidine: Competitive inhibition of histamine at H 2 receptors of the gastric parietal cells, which inhibits gastric acid secretion
- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience abdominal pain, heartburn, vomiting, or nausea. Have patient report immediately to prescriber signs of abdominal ulcers (severe abdominal or back pain; black, tarry, or bloody stools; vomiting blood or vomit that looks like coffee grounds; or weight gain or abnormal swelling), signs of aseptic meningitis (headache, fever, chills, severe nausea or vomiting, stiff neck, rash, sensitivity to bright lights, fatigue, or confusion), signs of high potassium (abnormal heartbeat, confusion, dizziness, passing out, weakness, shortness of breath, numbness or tingling feeling), signs of bleeding (vomiting blood or vomit that looks like coffee grounds; coughing up blood; hematuria; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any severe or persistent bleeding), signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), signs of severe cerebrovascular disease (change in strength on one side is greater than the other, difficulty speaking or thinking, change in balance, or vision changes), severe headache, severe dizziness, passing out, angina, severe diarrhea, shortness of breath, excessive weight gain, swelling of arms or legs, mood changes, depression, tinnitus, vision changes, or signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes) (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
