Glucagen 1mg Injection is used for emergency treatment of people with diabetes who have become unconscious because of very low blood sugar (severe hypoglycemia). It is used when such people are not able to take sugar by mouth. It may also be used in examinations of the gastrointestinal tract in adults. Glucagen 1mg Injection may be given by a healthcare professional or by the patient’s caregiver if they have been trained to use it. You and your family members should learn to recognize the symptoms of severe hypoglycemia (such as irritability, sweating, fast heart rate, feeling anxious or shaky etc) and how to administer this medicine. Do not use Glucagen 1mg Injection if it is discolored or if it contains particles. Glucagen 1mg Injection raises the blood sugar levels. Once the person gains consciousness and is able to eat, he or she must be given a high sugar snack like sweets, biscuits, or fruit juice. This will help prevent your blood sugar levels from falling again. It is important to get emergency medical assistance after using this medicine. Your doctor will monitor your blood sugar levels and keep you under observation for some time. A complete medical evaluation is advised for all such people to find out the cause of severe hypoglycemia (low blood sugar levels) and to prevent it from happening again. The most common side effect of this medicine is nausea. Please consult your doctor if it does not resolve or persists for a longer duration. Glucagen 1mg Injection may not work properly if you have been fasting for a long time or if your low blood sugar levels have been caused by drinking too much alcohol.
