Bentiromide, which is typically given as a one-time dose, is a peptide used as a screening test to find out if the pancreas is working properly. According to Wikipedia, Bentiromide is also used to “monitor the adequacy of supplemental pancreatic therapy”. It is worth noting that after bentiromide is broken down by the pancreas, a part of it appears in the urine. Your doctor can then assess the pancreatic function by measuring how much Bentiromide appears in the urine. Remember to call your doctor immediately if you start having trouble breathing, considering shortness of breath is a rare side effect that could nonetheless happen from time to time. As for the other side effects of Bentiromide, they include headache, diarrhea, nausea and vomiting. Apparently this peptide is safe during pregnancy and breastfeeding.
