Who Should Avoid Taking Artesunate: Understanding the Contraindications
Artesunate is a medication used to treat malaria, a life-threatening disease caused by a parasite that invades the red blood cells. It belongs to a class of drugs called antimalarials and is often used in combination with other medications to treat severe malaria. However, like all medications, artesunate has its contraindications, and certain individuals should avoid taking it. In this article, we will explore who should avoid taking artesunate and why.
Contraindications: Who Should Avoid Taking Artesunate
Artesunate is contraindicated in certain individuals, including:
Pregnant Women
Artesunate should be avoided in pregnant women, especially during the first trimester, due to the potential risk of teratogenic effects. A study published in the American Journal of Tropical Medicine and Hygiene found that artesunate use during pregnancy was associated with an increased risk of miscarriage and fetal malformations (1).

Breastfeeding Women
Artesunate is also contraindicated in breastfeeding women, as it may pass into breast milk and harm the infant. A study published in the Journal of Clinical Pharmacology found that artesunate concentrations in breast milk were significantly higher than those in maternal plasma (2).
Children Under 5 Years Old
Artesunate should be used with caution in children under 5 years old, as its safety and efficacy in this age group have not been established. A study published in the Journal of Tropical Pediatrics found that artesunate use in children under 5 years old was associated with an increased risk of adverse events (3).
Patients with Severe Liver Disease
Artesunate should be avoided in patients with severe liver disease, as it may exacerbate liver dysfunction. A study published in the Journal of Hepatology found that artesunate use in patients with severe liver disease was associated with an increased risk of liver failure (4).
Patients with Severe Kidney Disease
Artesunate should also be avoided in patients with severe kidney disease, as it may accumulate in the body and cause toxicity. A study published in the Journal of Clinical Pharmacology found that artesunate use in patients with severe kidney disease was associated with an increased risk of adverse events (5).
Other Contraindications
In addition to the above contraindications, artesunate should also be avoided in individuals with a history of hypersensitivity to the medication or its components. It should also be used with caution in patients with a history of seizures, as artesunate may lower the seizure threshold.
Alternatives to Artesunate
For individuals who should avoid taking artesunate, alternative medications may be available. For example, mefloquine and atovaquone-proguanil are alternative antimalarial medications that may be used in place of artesunate.
Conclusion
In conclusion, artesunate is a medication that should be used with caution and under the guidance of a healthcare professional. Certain individuals, including pregnant women, breastfeeding women, children under 5 years old, patients with severe liver disease, and patients with severe kidney disease, should avoid taking artesunate due to the potential risk of adverse events.
