What side effects does artesunate commonly cause?
Artesunate, an antimalarial drug, commonly causes mild to moderate side effects like dizziness, nausea, vomiting, and headache. These often resolve after treatment ends.[1]
How severe are artesunate's side effects for most patients?
Most patients experience transient effects such as fatigue, abdominal pain, and loss of appetite. Serious reactions like hemolytic anemia or delayed hemolysis occur in under 7% of cases, typically after high doses or prolonged use.[1][2]
What are rare but serious risks with artesunate?
Rare issues include severe allergic reactions (rash, itching, swelling), low white blood cell counts, elevated liver enzymes, and cardiac arrhythmias. Post-artemisinin delayed hemolysis can emerge 1-3 weeks after treatment, with hemoglobin drops up to 4 g/dL.2
Do side effects differ by how artesunate is given?
Intravenous artesunate links to higher risks of hemolysis and liver issues compared to oral forms. Children may see more gastrointestinal upset, while adults report frequent dizziness.1
How long do artesunate side effects last?
Common effects like nausea or headache fade within hours to days. Delayed hemolysis peaks at 7-14 days and resolves with supportive care, though monitoring for 4 weeks is standard.[2]
