Allergy medications: Know your options

Shots

Immunotherapy may be given as a series of shots, also called injections, usually one or two times a week. The dose may be increased during this time based on a person's tolerance. The highest tolerated dose can then be given year-round every 2 to 4 weeks.

Side effects might include irritation at the injection site and allergy symptoms such as, sneezing, congestion, hives, and itchy or watery eyes. Rarely, allergy shots can cause anaphylaxis.

Biological medicines given by injection include:

  • Dupilumab (Dupixent). This medicine treats asthma, sinus pressure and allergic skin conditions.
  • Omalizumab (Xolair). This medicine treats asthma or hives when other medicines don't help.
  • Mepolizumab (Nucala). This medicine treats asthma and sinus discomfort.
