ARV ADEs
and Mgmt Recommendations
Adverse Effect | Associated ARVs | Management |
---|---|---|
Bone marrow suppression | ZDV | Switch to another NRTI if possible. D/C concomitant bone marrow suppressant if possible. For neutropenia - Consider treatment with filgrastim. For anemia - Consider treatment with erythropoietin therapy. |
CV effects (including MI and CVA) | MI and CVA - PIs // MI only - ABC and ddI | Prevent or manage other CV risk factors; modify lifestyle risk factors |
CNS effects | EFV | Symptoms usually diminish or disappear within 2-4 weeks. |
GI intolerance | All PIs, ZDV, ddI | Sx may spontaneously resolve or become tolerable over time. If not, consider: For N/V - antiemetic prior to dosing. For D - bulk-forming agents (e.g. psyllium products), antimotility agents (e.g., loperamide), Ca tablets, pancreatic enzymes |
HS w/hepatic failure | NVP | D/C ARVs. r/o other causes of hepatitis. Hepatic injury may progress despite treatment discontinuation. Careful monitoring, don't rechallenge. Use other NNRTIs w/caution |
Hepatotoxicity | All NNRTIs (w/in first 12 wks); all PIs (after weeks to months); most NRTIs (w/in months to years); maraviroc | Rule out other causes of hepatotoxicity (EtOH, viral hepatitis, chronic HBV w/3TC, FTC, or TDF initiation or withdrawal; HBV resistance, etc.) // D/C all ARVs, construct a new regimen w/o the potential offending agent when serum transaminases are normal |
Hyperlipidemia | All PIs (except unboosted ATV); d4T; EFV > NVP | Lifestyle modifications, pharmacologic management (HIVMA/ACTG guidelines) |
Hypersensitivity Rxn (HSR) | ABC | d/c ABC and switch to another NRTI; r/o other causes of symptoms |
Insulin resistance/ DM | Thymidine analogs (ZDV, d4T); some PIs linked to insulin resistance and DM (but unclear if a class effect) | Consider using NNRTI if feasible; diet, exercise, pharmacologic mgmt |
Lactic acidosis/ hepatic steatosis +/- pancreatitis (severe mitochondrial toxicities) | NRTIs, esp. d4T, ddI, ZDV | For severe lactic acidosis, d/c all ARVs. Use NRTIs w/less propensity for mitochondrial tox (ABC, TDF, 3TC, FTC). Close monitoring of serum lactate after restarting NRTIs |
Lipodystrophy | Lipoatrophy - NRTIs (d4T > ZDV > TDF, ABC, 3CT, FTC), esp. when combined with EFV. Lipohypertrophy - PI- or NNRTI-based regimens and w/thymidine analogs (e.g., d4T, ZDV) | Lipoatrophy - switch from thymidine analogs to TDF or ABC, which may slow or halt progression and not fully reverse // Lipohypertrophy - Improvement in visceral fat seen in pts on LPV/r switched to ATV/r |
Nephrolithiasis/ urolithiasis/ crystalluria | IDV, ATV, FPV | Increase hydration, control pain, if possible switch to alternative agent |
Nephrotoxicity | IDV, TDF | Stop offending agent, generally reversible; Supportive care, electrolyte replacement as indicated |
Neuromuscular weakness syndrome (ascending) | d4T is ARV most frequently implicated | d/c ARVs. Recovery often takes months and ranges from complete recovery to substantial residual effects. DO NOT RECHALLENGE |
Osteonecrosis | Older PIs, but unclear whether caused by ARVs or by HIV | Decr weight bearing, remove/reduce risk factors |
Osteopenia r ostenecrosis | TDF or d4T; similar rate of bone loss with EPV or LPV/r based regimens over 96 wk period | Switch to other ARVs and stop other contributing drugs. Follow Natl Osteoporosis Fouondation Guidelines and/or IDSA Guidelines. Bisphosphate (alendronate qweek) |
Pancreatitis | ddI alone; ddI + d4T, hydroxyurea, ribavirin, or TDF. Rare reports with LPV/r | D/C offending agents. Manage symptoms of pancreatitis |
Peripheral neuropathy | ddI, d4T | D/C offending agents. Substitute alternate ART w/o potential for neuropathy. Pharmacologic mgmt - gabapentin, TCAs, lamotrigine, carbamazepine, topiramate, tramadol, narcotics |
SJ syndrome/ Toxic Epidermal Necrosis | NVP > DLV, EFR, ETR. Also reported with APV, FPV, ABC, DRV, ZDV, ddI, IDV, LPV/r, ATV | d/c all ARVs and any other possible agents |
Bleeding events | TPV/r - reports of ICH // PIs - incr bleeding in hemophiliac patients | D/C TPV/r and manage ICH w/supportive care // Hemophiliac patients may require increased use of factor VIII products |
