When should someone see an allergist?

As necessary: If your allergy symptoms are uncomfortable and/or interfere with your routine activities, you could try OTC's like Claritin, (loratadine) Zyrtec or Allegra 1st.. If they aren't effective, see a primary care doc for prescription meds and advice. If that's not effect, then see an allergist or ENT. On the other hand, if your allergies are severe (hives/ anaphylaxis/swelling of the throat) seek immediate care!

Depends..: On your expectation, disease severity, treatment response, other mitigating factor.

Several: *differentiate allergic conditions from mimics. *pinpoint the allergens causing the problem *Comprehensive history re. exposure and advice on avoidance measures. * allergy shots if medications and avoidance failed to control the disease or for people who desire a long-term solution to their allergic conditions. * More comprehensive knowledge on medication usage. *they are usually people-friendly
