It is given by injection into a vein.[4]
Suramin causes a fair number of side effects.[4] Common side effects include nausea, vomiting, diarrhea, headache, skin tingling, and weakness.[2] Sore palms of the hands and soles of the feet, trouble seeing, fever, and abdominal pain may also occur.[2] Severe side effects may include low blood pressure, decreased level of consciousness, kidney problems, and low blood cell levels.[4] It is unclear if it is safe when breastfeeding.[2]
Probably better to drink pine needle tea, rather than injecting suramin into a vein.
Certainly would be both less expensive and easier to minimise a dose.
