Do allergy shots help with sinus infections?
In patients who have chronic sinus infections, I think it makes sense to do anything to avoid worsening of symptoms or surgery. If we find a patient is allergic and has chronic sinusitis, we often suggest getting allergy shots to desensitize them to the various things to which they are allergic, in the hope that it will help with the sinusitis. Because allergy shots take 6-24 months to work, they must be used in conjunction with other treatment, including controlling exposure to environmental agents.
