Caution should be exercised while using ibuprofen with the following medicines:
- Acetylsalicylic acid or other NSAIDs may increase the risk of side effects. Care should be taken if acetylsalicylic acid is taken with coronary artery disease or cerebral circulation disorders, because ibuprofen can reduce the effect of acetylsalicylic acid.
- Angi-hypertensive agents: ibuprofen weakens the effect of antihypertensive drugs (including blockers of slow calcium channels and inhibitors of AMP).
- Methotrexate: Methotrexate excretion is slowed. Patients with reduced renal function have a high risk of developing hepatotoxic reactions, even with low doses of methotrexate (<20 mg / week).
- Some antacids may reduce the absorption of ibuprofen from the gastrointestinal tract, which may be important with prolonged administration of ibuprofen.
- Corticosteroids and selective serotonin reuptake inhibitors (incl. citalopram, fluoxegin, paroxetine, sertraline): increased risk of gastrointestinal bleeding.
- Cyclosporin and gold preparations increase the effect of ibuprofen on the synthesis of prostaglandins in the kidneys, which is manifested by an increased risk of perfrotoxicity.
- Mifepristone: NSAIDs should be started no earlier than 8-12 days after taking mifepristone, because NSAIDs may reduce the effectiveness of mifepristone.
- Tacrolimus: the simultaneous use of ibuprofen and tacrolimus increases the risk of nephrotoxicity.
- Zidovudine: simultaneous use of NSAIDs and zidovudine may lead to an increase in hematotoxicity. There is evidence of an increased risk of hemarthrosis and hematoma in HIV-positive patients with hemophilia who received co-treatment with zidovudine and ibuprofen.
- Antibiotics of the quinolone series: in patients receiving co-treatment with NSAIDs and quinolone antibiotics, an increased risk of seizures is possible.
- Joint use of ibuprofen with cefamandole, tsfoperazonom, cefogetan, valproic acid, plikamatsiyom increases the frequency of hypoprothrombinemia.
- Microsomal oxidation inductors (phenytoin, ethanol, barbiturates, rifampicin, phenylbugazone, tricyclic antidepressants) increase the production of hydroxylated active metabolites, increasing the risk of severe hepatotoxic reactions.
- Inhibitors of microsomal oxidation reduce the risk of hepatotoxic action of ibuprofen.
- The use of ibuprofen together with thiazide diuretics reduces their effectiveness.
The drug enhances the side effects of mineralocorticosteroids and glucocorticosteroids.
- Lithium: ibuprofen slows the excretion of lithium.
- Cardiac glycosides: NSAIDs can enhance the phenomena of heart failure, reduce the rate of glomerular filtration and cause an increase in the level of glycosides in the blood plasma.
- Caffeine strengthens the analgesic effect.
- Myelotoxic drugs increase manifestations of hematotoxicity of the drug.
- Drugs that block tubular secretion, reduce excretion and increase the plasma concentration of ibuprofen.
- Ibuprofen reduces the effectiveness of uricosuric medicines, enhances the effect of antiplatelet agents, fibrinolytic agents, thrombolytic drugs and insulin.
- Kolestyramine reduces the absorption of ibuprofen.
