Analgesics: NSAIDs (e.g., floctafenine): Risk of adverse/toxic effects. 

Loop Diuretics: Risk of diminishing the diuretic effect of loop diuretics.

Vitamin K Antagonists (warfarin): Risk of NSAIDs (nonselective) enhancing the anticoagulant effect of Vitamin K antagonists.

Use With Caution

NSAIDs: Risk of adverse/toxic effect of Antiplatelet Agents (decreased wound healing), increased risk of bleeding, and ofadverse/toxic effect of other NSAIDs.

Antibiotics: Quinolones: Risk of increasing the neuroexcitatory and/or seizure-potentiating effect of quinolone antibiotics and increasing the serum concentration of quinolone antibiotics.

ACE Inhibitors: Risk of adverse/toxic effect of NSAID agents: the combination may result in significantly decreasing renal function and of NSAIDs diminishing the antihypertensive effect of ACE Inhibitors.

AnticoagulantsRisk of antiplatelet agents enhancing the effect of anticoagulants.  

Antidepressants (Tricyclic, Tertiary Amine): Risk of enhancing the antiplatelet effect of NSAIDs (nonselective).

Beta-Blockers: Risk of NDSAIDs diminishing the antihypertensive effect of beta-blockers (Exceptions: levobunolol, metipranolol).

Clinical Implications

1. Consider the increased risk of excessive bleeding and delayed wound healing.

2. Cardiovascular effects:

  • Blood pressure
  • Risk of cardiovascular events, such as heart failure
  • Decrease in the cardioprotective effect of aspirin

3. Use extreme caution or avoid concurrent use with nephrotoxic agents.

4. Avoid ethanol: risk of gastric mucosal irritation.

5. Pregnancy and Lactation:

  • Studies have not demonstrated evidence of developmental abnormalities. However, because of the known effects of NSAIDs on the fetal cardiovascular system, use of ibuprofen during pregnancy should be avoided.
  • Only very small amounts of ibuprofen are found in breast milk.

    The latest conferences I attended about dealing with pain said we could prescribe up to 600 mg doses of Ibuprofen, with a maximum of 2400 mg daily. Your article mention max doses of 1200 mg. Has there been recent changes and the maximum level has lowered?

  3. James Noble March 20, 2013

    That must be a typo because my understanding is 2400mg for adults and 1200 mg for children.
