See the DrugPatentWatch profile for artesunate

Artesunate is a medication used to treat severe malaria, and it's crucial to administer it correctly to ensure its effectiveness and prevent adverse reactions. However, the available information does not provide specific guidance on adjusting the dosage of artesunate for allergic reactions.
It's important to note that allergic reactions to medications can range from mild to severe, and they may require different interventions. In general, if a patient experiences a mild allergic reaction, such as a rash or mild itching, medical professionals may consider continuing the medication while monitoring the patient closely.
However, if a patient experiences a severe allergic reaction, such as anaphylaxis, it's essential to discontinue the medication immediately and provide appropriate emergency care.
In any case, healthcare providers should follow standard protocols for managing allergic reactions, such as administering epinephrine, antihistamines, or corticosteroids, as necessary.
It's also important to note that the dosage of artesunate may need to be adjusted for other reasons, such as the patient's weight, age, kidney or liver function, or other medications they'�re taking.
Therefore, healthcare providers should always consult the drug's prescribing information and seek guidance from a pharmacist or other qualified healthcare professional when adjusting the dosage of any medication.
