MONITOR CLOSELY: The use of tumor necrosis factor (TNF) blockers with other immunosuppressive or myelosuppressive agents may increase the risk of infections. Serious infections and sepsis, including fatalities, have been reported with the use of TNF blockers, particularly in patients on concomitant immunosuppressive therapy. Agents that may be significantly myelo- or immunosuppressive include antineoplastic agents, radiation, zidovudine, linezolid, some antirheumatic agents, high dosages of corticosteroids or adrenocorticotropic agents (greater than 10 mg/day to 1 mg/kg/day, whichever is less, of prednisone or equivalent for more than 2 weeks), and long-term topical or inhaled corticosteroids. Concomitant use of TNF blockers with other immunosuppressants such as azathioprine or mercaptopurine may also increase the risk of a rare and often fatal cancer of white blood cells known as hepatosplenic T-Cell lymphoma (HSTCL), which has primarily been reported in adolescent and young adult males receiving treatment for Crohn's disease or ulcerative colitis. Cases of HSTCL have also occurred during use of these agents alone. Because individuals with rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, psoriatic arthritis, or plaque psoriasis may be more likely to develop lymphoma than the general population, it is difficult to assess the added risk of TNF blockers, azathioprine, and/or mercaptopurine.

MANAGEMENT: Patients receiving a TNF blocker alone or with other immunosuppressive or myelosuppressive agents should be monitored closely for the development of infections. TNF blocker therapy should be discontinued if a serious infection or sepsis occurs. Close monitoring for signs and symptoms of HSTCL (e.g., splenomegaly, hepatomegaly, abdominal pain, persistent fever, night sweats, weight loss) is also recommended during use of TNF blockers, particularly in combination with other immunosuppressants such as azathioprine and mercaptopurine.

GENERALLY AVOID: Grapefruit and grapefruit juice may significantly increase the plasma concentrations of dasatinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall induced by certain compounds present in grapefruit. Because grapefruit juice inhibits primarily intestinal rather than hepatic CYP450 3A4, the magnitude of interaction is greatest for those drugs that undergo significant presystemic metabolism by CYP450 3A4 (i.e., drugs with low oral bioavailability). In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict. Because dasatinib prolongs the QT interval, high plasma levels of dasatinib may increase the risk of ventricular arrhythmias such as torsade de pointes and sudden death.

MANAGEMENT: Patients treated with dasatinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Some authorities recommend close monitoring for toxicity (e.g., myelosuppression, bleeding complications, fluid retention, bradycardia or other conduction disturbances) and a reduction of dasatinib dosage to a range of 20 to 40 mg daily should be considered if there are no alternatives and concomitant use with a potent CYP450 3A4 inhibitor is necessary.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
