Can allergy shots really cause weight gain?

No: Allergy shots have no calories and don't increase one's appetite, so they do not cause weight gain.

Can receiving 7 allergy shots for the first time cause a fever?

The next day of my allergy shots I feel a little more tired/congested, is it caused by the allergy shot or the 'Singular' that I take?

The next day of my allergy shots I feel a little more tired/congested, is it caused by the allergy shot or the 'Singular' that I take?

M.D. visit/Mgt: It is not likely to be due to the Singulair (montelukast). Since you have nasal allergic disease under treatment with inhaled steroids and difficulty breathing, reviewing your allergic triggers and a follow up appointment is needed. I would suggest a pulmonary function test with and without a bronchodilator. ...Read more

Keep telling nurse my body itches on increase allergy shots decreased dose doesnt make me itch she says shots only itch at site after decrease works?

Keep telling nurse my body itches on increase allergy shots decreased dose doesnt make me itch she says shots only itch at site after decrease works?

Incorrect: Generalized itching after an allergy shot points to something more serious to come especially when the dose is increased . I urge you to discuss this with your allergist before you get your next shot. Although one may not need to decrease the allergen dose from a local reaction, a generalized itch may signal the early stage of anaphylaxis. ...Read more
