Side effects Flashcards
(38 cards)
Amphotericin B Deoxycholate
BW: do NOT exceed 1.5 mg/kg/day because of cardiopulmonary arrest
SE: infusion related rxn (fever, HA, malaise, rigors), decreased K, decreased Mg, NEPHROTOXICITY
*compatible with D5W only
*requires premedication to prevent infusion rxn:
- APAP, NSAID
-Benadryl, Hydrocortisone
-NS bolus to help with nephrotoxicity
- maybe meperidine to decrease rigors
Amphotericin B + Digoxin is a high risk of what?
Hypokalemia
Liposomal Amphotericin B (AmBisone
BW: cardiopulmonary arrst and death
SE: infusion rxn, nephrotoxicity (less likely), hypokalemia, hypomagnesia
Liposomal Amp B + Tacrolimus would be a higher risk of what?
Nephrotoxicity
Flucytosine (prodrug of fluoruracil)
mainly used for crypto!
MYELOSUPPRESSION
nephrotoxicity
hepatoxicity
hypokalemia
hypoglycemia
Common side effects for Azole antifungals
increased LFTs
QTc prolongation
DRUG INTERACTIONS
all IV to PO is 1:1
Fluconazole (Diflucan)
increased LFTs
QTc prolongation
DRUG INTERACTIONS
not recommended in pregnancy
penetrates into the CNS really well!!!! meningitis treatment :)
RENAL DOSING: CrCl < 50 decrease dose by 50%
Ketoconazole (Nizoral A-D)
increased LFTs - HEPATOTOXICITY = death
QTc prolongation
DRUG INTERACTIONS
Voriconazole (Vfend)
CI: coadministration with CYP inducers (barbituates, carbamazepine, efavirenz, quinidine, rifampin, ritonavir, sirolimus, St John’s Wart)
Warning: HEPATOTOXICITY, Phototoxicity, QTc
SE: visual changes, nephrotoxicity, CNS toxicity (hallucinations)
** good CNS penetration
Posaconazole (Noxafil)
CI: coadministration with some CYP inducers
Warning: QTc prolongation - correct Ca, K, Mg
Posaconazole + Vincristine creates increase risk of what?
Neurotoxicity (seizures, peripheral neuropathy, SIADH, parlytic ileus)
What azoles cause increase in INR?
Fluconazole + Voriconazole
Isavuconazoium (Isavuconazole)
CI: Use with CYP inducers or inhibitors
**Teratogenic
QTc prolongation
increased LFTs
Caspofungin (Cancidas)

Warning: Histamine related symptoms (pruritis, rash, swelling, hypotension)
SE: increased LFTs, HA, hypotension, hyperglycemia
Micafungin (Mycamine)

Warning: histamine related rxn (pruritus, rash, hypotension, swelling)
SE: increased LFTs, HA, hypotension, hyperglycemia
Nystatin
SE: N/V/D, stomach pain
- very low systemic risk due to low GI absorption
Terbinafine (Lamisil AT)
