How can pentamidine injection lower my blood sugar?

Yes. If you are taking pentamidine injections, your blood sugar may drop. This can happen shortly after administration of the injection. It is thought to be due to the toxic affect of pantamidine on pancreatic cells causing a massive release of insulin. Rarely, blood sugar may go very low. Symptoms may be severe and can happen after you stop taking pentamidine. It may also happen with nebulized pentamidine. They include:
  • nervousness
  • cold sweats
  • clammy feeling
  • dizziness
  • weakness
  • unusual hunger
  • abnormal heartbeat
  • blurred vision
  • confusion
  • slurred speech

Call your doctor if you have any symptoms of low blood sugar.  Family members should call 911 immediately if there is a loss of consciousness.
After repeated doses, the pancreatic cells may be unable to release enough insulin causing high blood sugar.
