Heavy breathing and a rapid pulse are more severe symptoms. If uncorrected, prolonged hyperglycemia or diabetic acidosis can result in loss of consciousness or death. Therefore, it is important that you obtain medical assistance immediately. If you notice either of these conditions, consult your doctor. A change in your injection technique may help alleviate the problem.
Patients occasionally experience redness, swelling, and itching at the site of injection of insulin.
This condition, called local allergy , usually clears up in a few days to a few weeks. In some instances, this condition may be related to factors other than insulin, such as irritants in the skin cleansing agent or p.o. injection technique. If you have local reactions, contact your doctor. Less common, but potentially more serious, is generalized allergy to insulin , which may cause rash over the whole body, shortness of breath, wheezing , reduction in blood pressure , fast pulse, or sweating. Severe cases of generalized allergy may be life threatening.
