Answer to Question 1

A
Folinic acid is given with pyrimethamine to minimize adverse effects, and the dose is 10 to 15 mg twice daily, given with the pyrimethamine dose. The medication is given orally. The dose should be cut in half, not increased, after 2 to 4 days. Muscle pain and joint stiffness are adverse effects of sodium stibogluconate.

Answer to Question 2

A
Suramin sodium can cause severe side effects, including a shock-like syndrome with IV dosing. A small test dose should be given initially to make sure this is not likely. Patients receiving pen-tamidine should be supine while receiving that drug. It is not necessary to provide a fatty snack with suramin or to obtain LFTs before administration.
