Long-Term Effects

  • See "What Are Side Effects Associated with Using Edaravone?"


  • Hypersensitivity reactions (redness, wheals, and erythema multiforme) and cases of anaphylaxis (hives, decreased blood pressure, and shortness of breath) reported; monitor for hypersensitivity reactions; if hypersensitivity reactions occur, discontinue the drug, treat per standard of care, and monitor until the condition resolves
  • Contains sodium bisulfite, which may cause allergic-type reactions, including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in susceptible people; sulfite sensitivity occurs more often with a history of asthma

Pregnancy and Lactation

  • There are no adequate data on the developmental risk associated with the use of edaravone in pregnant women. In animal studies, administration of edaravone to pregnant rats and rabbits resulted in adverse developmental effects (increased mortality, decreased growth, delayed sexual development, and altered behavior) at clinically relevant doses; most of these effects occurred at doses that were also associated with maternal toxicity. Consult your doctor.
  • It is unknown if edaravone is distributed in human breast milk. Edaravone is excreted in the milk of lactating rats. Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for edaravone, and any potential adverse effects on the breastfed infant from the drug or the underlying maternal condition.
