None.
There is no FDA black box warning for Afinitor Disperz. However, serious infections, including opportunistic infections, may occur.
Hematologic toxicity (neutropenia, thrombocytopenia, anemia), infection risk, peripheral neuropathy, cardiotoxicity (heart failure), embryo-fetal toxicity.
Non-infectious pneumonitis (including interstitial lung disease) has been reported; monitor for symptoms and consider interruption or discontinuation.,Increased risk of infections, including opportunistic infections (e.g., Pneumocystis jirovecii, TB); monitor and treat promptly.,Increased serum creatinine and proteinuria may occur; monitor renal function.,Angioedema, including life-threatening cases, can occur, especially in patients taking ACE inhibitors.,Stomatitis and mouth ulcers are common; manage with topical treatments and dose modification.,Impaired wound healing; use with caution perioperatively.,Increased risk of bleeding, especially in patients with renal angiomyolipoma and TSC.,Fetal harm can occur; advise effective contraception during treatment.

Hypersensitivity to everolimus, sirolimus, or any component of the formulation,Severe hepatic impairment (Child-Pugh class C) (relative contraindication; use with caution in moderate impairment)
Avoid alcohol. No specific food interactions, but maintain a balanced diet. Take with food or milk if gastrointestinal upset occurs.
Avoid grapefruit, grapefruit juice, and Seville oranges due to CYP3A4 inhibition. Avoid high-fat meals, as they reduce absorption; take on empty stomach or with light fat-free meal. St. John's wort reduces everolimus levels and should be avoided.
First trimester: Increased risk of major congenital malformations (neural tube defects, cardiovascular anomalies) based on animal studies and limited human data. Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and preterm birth. Avoid in pregnancy unless benefit outweighs risk.
Pregnancy Category D. Animal studies show embryotoxicity and fetotoxicity at subtherapeutic doses. First trimester: risk of major malformations. Second/third trimester: risk of fetal growth restriction, oligohydramnios, and spontaneous abortion.
No data on excretion in human milk; M/P ratio unknown. Due to potential for serious adverse reactions in breastfed infants, breastfeeding is not recommended during treatment and for at least 2 weeks after last dose.
No data on excretion in human milk; M/P ratio unknown. Due to potential serious adverse reactions in nursing infants (e.g., immunosuppression), breastfeeding is contraindicated during treatment and for 2 weeks after last dose.
No specific dosing adjustments established for pregnancy. Pregnancy-induced pharmacokinetic changes (increased volume of distribution, enhanced renal clearance) may reduce drug exposure; consider therapeutic drug monitoring if available.
No specific dose adjustments established for pregnancy. Pharmacokinetic changes (increased volume of distribution, altered metabolism) may reduce exposure; however, due to teratogenicity, use is not recommended unless benefit outweighs risk. Dose adjustments based on therapeutic drug monitoring are not validated.
AURLUMYN is a proprietary name for auranofin, an oral gold compound used for rheumatoid arthritis. Monitor for oral ulcerations, dermatitis, and proteinuria. Renal function and CBC should be checked monthly. Avoid concurrent use with penicillamine, antimalarials, immunosuppressants, or cytotoxic drugs. Onset of action may be delayed 3-6 months.
AFINITOR DISPERZ (everolimus) is an m TOR inhibitor; tablets for oral suspension are not interchangeable with regular tablets due to different pharmacokinetics. Monitor for non-infectious pneumonitis, rash, stomatitis, metabolic effects (hyperglycemia, hyperlipidemia), and renal impairment.
