Do allergy shots cause body weight changes?
6 doctors weighed in across 2 answers
No: Allergy shots don't have calories nor increase a person's appetite, so do not cause weight gain. However, if the shots worked well and a person got rid of his stuffed up nose, sneezing, watery eyes, or other bothersome symptoms, then the person would be happier and feeling a lot better. Then, he might develop a bigger appetite, go out more often, and end up eating more calories and gaining weight.

No: Some older allegy medicines increase appetite. In fact Cyproheptadine has been used to help underweight kids. Allergy shots dont do this at all.
