Deferasirox Disease Interactions

There are 5 disease interactions with deferasirox:

Major

Deferasirox (Includes Deferasirox) ↔ Bone Marrow Suppression

Severe Potential Hazard, Moderate plausibility

Applies to: Immunodeficiency, Thrombocytopenia

The use of deferasirox is contraindicated in patients with platelet counts below 50 x 109/L. Cytopenias, worsening anemia, and thrombocytopenia, including fatal events, have been reported in patients treated with deferasirox. Preexisting hematologic disorders may increase this risk. It is recommended to monitor blood counts in all patients and to interrupt treatment in patients who develop cytopenias until the cause of the cytopenia has been determined.

Moderate

Deferasirox (Includes Deferasirox) ↔ Auditory And Ocular Abnormalities

Moderate Potential Hazard, Moderate plausibility

Applies to: Hearing Loss, Visual Defect/Disturbance

Auditory disturbances (high-frequency hearing loss, decreased hearing), and ocular disturbances (lens opacities, cataracts, elevations in intraocular pressure, and retinal disorders) have been reported in patients using deferasirox . It is recommended to perform auditory and ophthalmic testing (including slit lamp examinations and dilated fundoscopy) before starting therapy with deferasirox and thereafter as clinically indicated. If disturbances are noted, consider dose reduction or interruption if appropriate.

Moderate

Deferasirox (Includes Deferasirox) ↔ Gi Complication

Moderate Potential Hazard, Moderate plausibility

Applies to: Thrombocytopenia, Esophageal Ulceration with Bleeding

Gastrointestinal hemorrhage, ulcerations, perforations, including deaths have been documented in patients using deferasirox, especially in elderly patients who had advanced hematologic malignancies and/or low platelet counts. The risk of gastrointestinal hemorrhage may be increased when administering deferasirox in combination with drugs that have ulcerogenic or hemorrhagic potential, such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, oral bisphosphonates, or anticoagulants. It is recommended to monitor patients and discontinue therapy for suspected GI ulceration or hemorrhage. Care is recommended when using this agent in patients at risk of GI complications.

Moderate

Deferasirox (Includes Deferasirox) ↔ Hepatic Impairment

Moderate Potential Hazard, Moderate plausibility

Applies to: Liver Disease

The use of deferasirox should be avoided in patients with severe hepatic impairment. The starting dose of deferasirox should be reduced by 50% in patients with moderate hepatic impairment. It is recommended to measure serum transaminases and bilirubin in all patients prior to initiating treatment, every 2 weeks during the first month, and at least monthly or more frequently as clinically appropriate. Closely monitor patients with mild or moderate hepatic impairment for efficacy and adverse reactions that may require dose titration.

Moderate

Deferasirox (Includes Deferasirox) ↔ Renal Dysfunction

Moderate Potential Hazard, Moderate plausibility

Applies to: Renal Dysfunction

The use of deferasirox is contraindicated in patients with serum creatinine greater than two times the age-appropriate upper limit of normal or creatinine clearance less than 40 mL/min. The starting dose of deferasirox should be reduced by 50% in patients with creatine clearance 40 to 60 mL/min. It is recommended to measure serum creatine and calculate clearance in duplicate prior to initiating treatment in all patients and monitor renal function at least monthly or more frequently as clinically appropriate. Consider dose reduction, interruption, or discontinuation of deferasirox based on increases in serum creatinine.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
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 information available.
