Artesunate is an antimalarial medication used to treat severe malaria infections [2]. However, an overdose of artesunate can lead to several symptoms. According to the Mayo Clinic, the symptoms of an artesunate overdose include chest pain or discomfort, confusion, decreased urine output, dizziness, fainting, fast, pounding, or irregular heartbeat or pulse, headache, irregular breathing, nausea, nervousness, rapid weight gain, seizures, severe sleepiness, shortness of breath, swelling of the face, fingers, feet, or lower legs, tightness in the chest, unusual tiredness or weakness, and vomiting [3]. The severity of the symptoms can vary depending on the amount of artesunate ingested. Therefore, it is essential to seek medical attention immediately if an artesunate overdose is suspected [2].
