Allergy Treatment

The best approach to the atopic (environmental allergy) patient is to first allergy skin test the patient to make sure that they have environmental allergies. Once you have a positive skin test for environmental allergies in dog and cat, you then can recommend both specific and non-specific therapies for atopy. The next step after confirming the diagnosis of atopy with the allergy skin test is to check for a co-existing food allergy, by doing an elimination food trial over the next 6-8 weeks. During this time you can commence treatment for atopy. The best treatment for atopy causes multi-modal therapy utilizing both specific, non-specific treatment and controlling infection in dog and cat.


The 4 Keys To Success

  1. Diagnose and treat any bacterial and or yeast infections caused by the allergic disease. These infections will produce odour, contribute to the itch and will upregulate allergic disease in cat and dog (make the allergies worse)
  2. Diagnose and control any concurrent food allergies (approximately 30% of atopic patient will also have food allergies attributing to the itching)
  3. Non-Specific treatment for atopy
  4. A) Drugs Treatment

    • Cyclosporine (atopica) ~60% effective, expensive, few side effects

    • Antihistamines, ~20-30% effective, few side effects

    • Essential Fatty Acids- helps ~20-50% of cases =fish, borage, flaxseed oil

    • Cortisone (Corticosteroids) ~70-80% effective, cheap, lots of side effects

    • Pentoxyfylline- helps reduce cortisone dosage, never used by itself


  5. Specific therapy treatment for atopy
  6. A) Avoidance

    • Reduce exposure to offending allergens, not practical in all cases, works well with house dust mites in the house

    B) "Allergy Shots" (A.S.I.T. =Allergy Specific Immuno Therapy)

    • The atopic cat or dog receives weekly or biweekly/monthly injections of allergens that were positive on the allergy skin test. A good to excellent response is seen in 60-75% of atopic patients. The response is rarely seen in the first month of therapy. The majority will show improvement in the first 3-4 months. Some will show improvement after 6-12 months

  • "I don't have enough positive words to describe how thankful I am about Dr. Charach expertise and his team's kindness...I wish I had found Dr. Charach before spending thousands of dollars with no results. I don't consider his fees unreasonable considering the amazing results I had. The clinic's staff was very organized, super nice and knowledgeable. 5 stars all the way to Dr. Charach and the clinic's team."

  • "Absolutely amazing Doctor along with the receptionist! We traveled from Calgary to see Dr.Charach and our dog left the clinic with relief. Not only did he have fabulous attention and care for our dog, he also had it for my husband and I as we were a mess as we had no idea what was wrong nor did the Vets in Calgary. Our dog is still needing care and Dr.Charach and his team still provide amazing service over the phone!"
