Drug ACE inhibitors: May decrease antihypertensive effects. Monitor BP closely.

Acetazolamide: May cause accumulation and toxicity of acetazolamide, resulting in CNS depression, metabolic acidosis, anorexia, and death. Administer together with caution and monitor patient for toxicity.

Ammonium chloride and other urine acidifiers: May increase levels of aspirin products. Watch for aspirin toxicity.

Antacids in high doses and other urine alkalinizers: May decrease levels of aspirin products. Watch for decreased aspirin effect.

Anticoagulants, antiplatelet agents: May increase risk of bleeding. Use with extreme caution if these drugs must be used together.

Beta blockers: May decrease antihypertensive effect. Avoid long-term aspirin use if patient is taking antihypertensives.

Corticosteroids: May enhance salicylate elimination and decrease drug level. Watch for decreased aspirin effect.

Diuretics: May decrease effectiveness of diuretics in patients with underlying renal or CV disease. Monitor patient for effectiveness.

Heparin: May increase risk of bleeding. Monitor coagulation studies and patient closely if used together.

Ibuprofen, other NSAIDs: May negate the antiplatelet effect of low-dose aspirin therapy.

Occasional use of ibuprofen is unlikely to have a negative effect.
