Yes, it’s possible but extremely rare. Allergic reactions to artesunate can occur and, in rare cases, can be life-threatening (anaphylaxis). Because of this, artesunate is given under medical supervision with monitoring for any signs of an allergic reaction.
What to watch for (seek urgent care if these appear):
- Skin: hives, itching, swelling, widespread rash
- Breathing: shortness of breath, wheezing, throat tightness, hoarseness
- Circulation: dizziness, fainting, pale or clammy skin, rapid or weak pulse
- Other: tongue or lip swelling, severe nausea/vomiting
If an allergic reaction is suspected during treatment:
- Stop the infusion immediately
- Call emergency services or go to the nearest hospital
- Treatment may include epinephrine, steroids, antihistamines, fluids, and airway support as needed
Important notes:
- The overall risk of a severe allergic reaction to artesunate is very low, especially when the drug is given in a controlled clinical setting.
- If you have a known allergy to artesunate or other artemisinin-based drugs, tell your healthcare provider before starting treatment.
- Benign side effects (not related to allergy) and other risks (e.g., post-treatment hemolysis, liver test changes) exist; discuss any concerns with your clinician.
