Can chronic allergy improve after immunotherapy?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 19-year-old college athlete who suffers from year-round nasal congestion, sneezing, and watery eyes, especially when training outdoors. My allergist confirmed dust mite and pollen allergies. I have been on antihistamines, but they make me drowsy during classes. Please tell me;

  1. Could immunotherapy (allergy shots or drops) provide long-term relief?

  2. How soon would I notice improvement?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Allergy immunotherapy, whether given as shots or under-the-tongue drops, is often recommended for people like you who have persistent symptoms despite standard medicines and who want a long-term solution rather than daily pills.

Unlike antihistamines, which only control symptoms temporarily, immunotherapy works by gradually retraining your immune system to become less reactive to allergens such as pollen and dust mites. This can provide lasting relief even years after completing treatment. Most patients start to notice improvement within six months to a year, though full benefit may take two to three years of regular therapy, and the earlier it is started, the better the long-term results tend to be.

For athletes and students, it can be helpful since it reduces the need for sedating medications and improves quality of life during training and studies. Your allergist can guide you on whether shots or drops are better for you based on convenience, safety, and the types of allergens involved. But both approaches have strong evidence of effectiveness in young people with your type of allergic rhinitis.

I hope this information helps you.

Feel free to ask further queries.

Thank you.
