What Leptin Is. Leptin is a hormone secreted by adipose tissue (fat cells) that tells you youâre full. (Its opposite hormone is called ghrelin, which tells you youâre hungry. You can remember this because the word ghrelin sounds like a stomach growling.) Because leptin is secreted by fat cells, you produce more leptin as your weight increases.
Epinephrine is the most effective treatment for anaphylaxis, and the shot should be given right away (usually in the thigh). If youâve had an anaphylaxis reaction before, you should carry at least two doses of epinephrine with you at all times.
If anaphylaxis occurs after injection of allergen-specific subcutaneous immunotherapy (SCIT), a large local reaction often occurs. Place a tourniquet above the injection site and, after IM epinephrine is administered, inject up to 0.1 mL of epinephrine into the large local reaction site to slow absorption.
