Acceptability and effectiveness of self-administered intramuscular insulin in juvenile-onset diabetes

Four juvenile-onset diabetic patients, poorly controlled on subcutaneous insulin, received twice-daily, self-administered intramuscular insulin, using a 25g 1 needle. All patients reported the intramuscular route to be as acceptable as the subcutaneous route. In one patient, the intramuscular route produced a marked improvement in diabetic control.
