The drug should be taken with caution when taking the following medicines at the same time:
- Urikozuric means (reduces their effectiveness);
- indirect anticoagulants, antiaggregants, fibrinolytics (
ibuprofen strengthens their effect, increases the risk of hemorrhagic complications);
- corticosteroids and other non-steroidal anti-inflammatory drugs, colchicine, estrogen, ethanol (
ibuprofen increases the risk of violations from the gastrointestinal tract);
- cardiac glycosides, lithium, methotrexate (
ibuprofen can enhance the toxic effects of these drugs);
- acetylsalicylic acid (
ibuprofen reduces the anti-inflammatory and antiaggregant effect of this drug - it is possible to increase the incidence of acute coronary insufficiency in patients receiving small doses of acetylsalicylic acid as antiplatelet agents after the onset of ibuprofen administration.
- inducers of microsomal oxidation (
phenytoin,
ethanol, barbiturates,
rifampicin,
phenylbutazone, tricyclic antidepressants) (production of hydroxylated active metabolites increases, increasing the risk of severe hepatotoxic reactions);
- inhibitors of microsomal oxidation (the risk of hepatotoxic effect is reduced);
- diuretics (
furosemide and hydrochlorothiazide) and vasodilators (including slow calcium channel blockers and angiotensin-converting enzyme inhibitors): simultaneous administration can reduce the antihypertensive activity of drugs;
- caffeine (enhances analgesic effect);
- cefamandol, cefaperazone, cefotetan, valproic acid, plikamycin (the frequency of development of hypothrombinemia increases);
- cyclosporine (nephro- and hepatotoxic effects increase) and with gold preparations (nephrotoxic effect increases);
- Myelotoxic drugs (the hematotoxic effect is enhanced);
- probenecid and sulfinpyrazone (
ibuprofen, like other NSAIDs, can reduce the effect of these drugs);
- quinolone antibacterial drugs in high doses (can cause convulsions);
- drugs that block tubular secretion (reduced excretion and increased plasma concentration of ibuprofen);
- antacids and colestyramine (reduces absorption of ibuprofen);
- oral hypoglycemic drugs (
ibuprofen can potentiate the hypoglycemic effect of these drugs).
