Interactions between your drugs

Moderate

testosterone deflazacort

Applies to: Duratest (testosterone) and Emflaza (deflazacort)

MONITOR: Concomitant use of androgens with adrenocorticotropic hormone (ACTH) or corticosteroids may result in increased fluid retention and edema due to additive steroidal effects.

MANAGEMENT: Caution is advised if androgens are used in combination with ACTH or corticosteroids, particularly in patients with conditions that may be aggravated by fluid retention such as cardiovascular, renal, or hepatic diseases.

Drug and food interactions

Moderate

deflazacort food

Applies to: Emflaza (deflazacort)

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of 21-desdeflazacort, the active metabolite of deflazacort that is formed by esterases after oral administration and further metabolized by CYP450 3A4 to several inactive metabolites. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism in the gut wall by certain compounds present in grapefruit. 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. Increased systemic exposure to 21-desdeflazacort may increase the risk of corticosteroid adverse effects such as hypercorticism, hyperglycemia, adrenal suppression, immunosuppression, hypertension, salt and water retention, electrolyte abnormalities, behavioral and mood disturbances, posterior subcapsular cataracts, glaucoma, bone loss, and growth retardation in children and adolescents.

MANAGEMENT: Deflazacort should not be administered with grapefruit juice.

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.
