Drug Allergy Evaluations In Arizona

Drug Allergy Evaluations

If you have a drug allergy, you can be a bit confused when symptoms are experienced. Dr. Rishi at Arizona Allergy Associates has provided useful information about drug allergies and when to see a professional.

Symptoms of a Drug Allergy

When the body senses an invader, it begins to attack and causes what are known as allergy symptoms. Take note of any symptoms you experience after taking medication if you suspect an allergy. Some signs include:

  • A skin rash
  • Wheezing & problems breathing
  • Swelling
  • Itching
  • Vomiting
  • Dizziness or feeling lightheaded
  • Anaphylaxis

Evaluating & Diagnosing Drug Allergies

Allergies to drugs can be difficult for a clinician to diagnose. Penicillin allergies are the only definitive diagnoses of a drug allergy that can be made by skin tests. Reactions can be similar to symptoms of certain diseases, making it imperative that your allergist asks plenty of questions. Some of these questions may include:

  • What drugs are you taking that may be the cause of this reaction?
  • Have you started any new medications recently?
  • How long did you take the drug before noticing symptoms?
  • Have you stopped taking the medication?
  • How long did the symptoms you experienced last?
  • What methods are you using to relieve symptoms effectively?
  • Do you take vitamin supplements or herbal medicines?

All of this information is useful in helping your clinician make an accurate diagnosis and treat symptoms safely and effectively.
