What dosing is used for artesunate (adult and pediatric)?
The dosing for artesunate depends on the indication (most commonly malaria) and the patient’s weight/age, plus whether the patient can take oral medicines.
If you tell me the country’s guideline you’re following (WHO, CDC, local national guideline) and the clinical situation (severe malaria needing IV/IM vs uncomplicated oral malaria), I can give the exact regimen.
How is artesunate dosed for severe malaria (IV/IM)?
For severe malaria, artesunate is typically given by IV or IM dosing based on body weight, then transitioned to a full course of an oral antimalarial once the patient can take oral therapy. The exact mg/kg schedule varies by guideline and local product concentration.
What dosing is used for uncomplicated malaria (oral artesunate)?
For uncomplicated malaria, oral artesunate is usually used as part of combination therapy (most often with a partner drug). Doses are again weight-based and depend on the duration of the regimen (for example, 3 days in many “artesunate + partner” protocols).
Dosing by weight: what information do you need?
Most artesunate regimens are calculated by body weight using mg/kg (often for 3-day or multi-dose schedules). To calculate correctly, you need:
- Patient weight (kg)
- Whether this is severe vs uncomplicated malaria
- Route available (IV/IM vs oral)
- Age and pregnancy status (often affects preferred regimens)
What are common adult dosing errors to avoid?
The most frequent problems are:
- Using mg/kg schedules for the wrong indication (severe vs uncomplicated)
- Giving the wrong total daily dose when converting from IV/IM strength to volume
- Continuing IV/IM doses after the patient has recovered enough for oral therapy (or the opposite: switching too early)
Where can I verify the exact mg/kg and schedules?
Because artesunate dosing differs across guidelines and product concentrations, the most reliable way to match the exact regimen is to use an authoritative dosing reference for your region (WHO/CDC or your national malaria protocol) and the specific formulation you have.
If you share:
1) severe or uncomplicated malaria,
2) adult vs child (and weight in kg),
3) route (IV/IM/oral),
I’ll translate that into the exact dosing schedule in mg/kg and the corresponding number of mL per dose for common concentration ranges.
