Summary
Most interaction-specific and quantitative claims are not supported by the provided CALDOLOR (ibuprofen injection) label excerpts. The label provided mainly supports boxed warnings for cardiovascular thrombotic events and serious GI bleeding/ulceration/perforation, plus contraindication in CABG; all other asserted interactions and dosing/population limitations are unsupported or contradict the provided label (e.g., ulcer and CKD contraindication-like statements, and CABG timing).

Accurate Statements
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID).
Supported indirectly by label context (CALDOLOR boxed warning and warnings refer to NSAIDs including ibuprofen).
Combining ibuprofen with certain prescription medications increases the risks of gastrointestinal bleeding.
Partially supported: label states concomitant use of oral corticosteroids, aspirin, anticoagulants, or SSRIs increases risk of GI bleeding (5.2 Risk Factors).
Combining ibuprofen with certain prescription medications increases the risks of kidney damage.
Not supported by provided excerpts; no kidney-damage warning/interaction text is included.
Unsupported Statements
Combining ibuprofen with certain prescription medications increases the risks of kidney damage.
No kidney-damage warning/interaction is present in the supplied CALDOLOR label excerpts.
Combining ibuprofen with certain prescription medications can reduce drug efficacy.
No such efficacy-reduction statement is present in the supplied excerpts.
Ibuprofen increases bleeding risk with anticoagulants and antiplatelets.

No warfarin/bleeding-time information is present in the supplied excerpts.
Ibuprofen combined with prescription-dose aspirin amplifies antiplatelet effects.
The provided excerpt says concurrent use of aspirin and an NSAID increases risk of serious GI events; it does not support an antiplatelet-effect amplification claim.

No quantitative blood-pressure change information is present in the supplied excerpts.
Ibuprofen with diuretics (e.g., furosemide) can cause fluid retention.
No diuretic/fluid retention interaction information is present in the supplied excerpts.
Ibuprofen with diuretics (e.g., furosemide) raises blood pressure by 5 to 10 mmHg on average.
No quantitative blood-pressure change information is present in the supplied excerpts.
Ibuprofen interferes mildly with beta-blockers via kidney effects.
No beta-blocker interaction or kidney-effects rationale is present in the supplied excerpts.
Ibuprofen with metformin or insulin has rare direct interaction.
No metformin/insulin interaction information is present in the supplied excerpts.
The combination of ibuprofen with metformin or insulin can increase kidney strain.
No metformin/insulin or kidney-strain interaction information is present in the supplied excerpts.
The combination of ibuprofen with metformin or insulin increases lactic acidosis risk due to kidney strain.
No lactic acidosis or related mechanistic claim is present in the supplied excerpts.
Ibuprofen with digoxin can lead to toxicity by slowing digoxin clearance.
No digoxin interaction information is present in the supplied excerpts.
Ibuprofen with lithium can lead to toxicity by slowing lithium clearance.
No lithium interaction information is present in the supplied excerpts.
Ibuprofen raises lithium levels by 25%.
No quantitative lithium-level information is present in the supplied excerpts.
Combining ibuprofen with SSRIs (e.g., sertraline) doubles the risk of gastrointestinal bleeding compared to SSRIs alone.
The label excerpt only states concomitant use of SSRIs increases GI bleeding risk; it does not provide a 'doubles' quantitative comparison.
Ibuprofen with opioids (e.g., oxycodone) is generally safe.
No opioid coadministration safety statement is present in the supplied excerpts.
Ibuprofen with opioids (e.g., oxycodone) adds constipation and sedation.
No opioid-specific additive constipation/sedation claim is present in the supplied excerpts.
Combining ibuprofen with corticosteroids (e.g., prednisone) quadruples ulcer risk.
The label excerpt notes concomitant oral corticosteroids increase GI bleeding risk, but provides no 'quadruples' quantitative ulcer-risk value.
Ibuprofen with corticosteroids (e.g., prednisone) is advised only for short-term use.
No short-term-only advice regarding corticosteroid pairing is present in the supplied excerpts.
Avoid long-term pairing of ibuprofen with corticosteroids without gastroprotection like PPIs.
No long-term pairing advice or PPI gastroprotection recommendation is present in the supplied excerpts.
Ibuprofen with immunosuppressants like cyclosporine or tacrolimus increases toxicity due to reduced kidney filtration.
No cyclosporine/tacrolimus interaction information is present in the supplied excerpts.
Ibuprofen increases methotrexate levels dangerously.
No methotrexate interaction information is present in the supplied excerpts.
Ibuprofen increases the risk of bone marrow suppression when combined with methotrexate.
No methotrexate/bone marrow suppression information is present in the supplied excerpts.
Methotrexate in high doses is contraindicated with ibuprofen.
No methotrexate contraindication is stated in the supplied excerpts.
Low doses of ibuprofen (200–400 mg) and short courses minimize risks for most people.
No ibuprofen dose range for CALDOLOR and no 'most people' generalization is present in the supplied excerpts (the label only advises lowest effective dose for shortest duration possible to minimize CV risk).
Ibuprofen is not for people with ulcers.
The provided excerpts do not state an absolute contraindication for 'ulcers'; they discuss increased risk in patients with prior peptic ulcer disease and/or GI bleeding.
Ibuprofen is not for people with chronic kidney disease (CKD).
No CKD contraindication or restriction is present in the supplied excerpts.
Ibuprofen is not for people with recent heart surgery.
The supplied label only specifies contraindication in CABG setting; it does not support a blanket statement for 'recent heart surgery.'
Contradictions
Low
AI Statement
Ibuprofen is not for people with recent heart surgery.
Label Reference
Contraindication is specifically 'In the setting of coronary artery bypass graft (CABG) surgery' and 'NSAIDs are contraindicated in the setting of CABG.' (4 Contraindications; 5.1 Status Post CABG Surgery).
Important Omissions
No claim in the AI response was explicitly aligned to the CALDOLOR boxed warnings regarding increased risk of serious cardiovascular thrombotic events (MI/stroke) and serious GI bleeding/ulceration/perforation, including age/risk-factor considerations, despite being central to the provided label excerpts.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
High
Multiple interaction claims are unsupported by the provided label excerpts, including specific agents and quantitative risk changes; several absolute contraindication-like statements (ulcers, CKD) are also unsupported and could mislead. The only supported content pertains to general NSAID GI risk factors (including certain concomitant drug classes) and the CABG contraindication.

Primary Issue
Major portions of the response include unsupported drug-drug interaction specifics and quantitative risk statements not found in the supplied CALDOLOR label excerpts; several absolutist population restrictions/conflict with the label’s specificity.
Suggested Improvement
Restrict claims to what is supported by the provided label excerpts: (1) NSAID boxed warnings for CV thrombotic events and serious GI bleeding/ulceration/perforation; (2) GI bleeding risk factors including concomitant oral corticosteroids, aspirin, anticoagulants, and SSRIs; (3) contraindication specifically in the CABG setting; (4) advise lowest effective dose for shortest duration possible to minimize CV risk. Remove or qualify unsupported interactions and quantitative percentages/level changes.
