Cat & Dog Allergy Options

Allergy shots, allergy drops, or an at-home spray?

If you are searching for cat allergy shots or dog allergy drops, you are looking at the same underlying science OLLEREG uses. Every treatment for cat allergy and dog allergy below works by exposing your immune system to the same dander proteins you react to. The difference is how the dose is delivered, what it costs, and how much of your life it takes up.

Cat allergy shots & dog allergy shots

Allergy shots (subcutaneous immunotherapy) are given by injection at an allergist's office. For pet dander they typically mean a build-up phase of weekly visits, then maintenance injections every few weeks, with a waiting period in the clinic after each dose. Effective, and the longest-established option, but it is built around needles and a clinic schedule. Typical cost runs $1,500 to $4,000 a year before insurance.

Cat allergy drops & dog allergy drops

Allergy drops (sublingual immunotherapy, or SLIT) put liquid allergen extract under the tongue at home instead of into your arm. No needles, no clinic visits. This is what services like Curex, Wyndly and Quello provide. Pricing is usually $50 to $89 a month, and most also charge a separate consultation fee.

OLLEREG whole-mouth spray

OLLEREG is Oromucosal Immunotherapy (OMIT). Same category of allergen extract as drops, delivered as a spray that coats your cheeks, gums and under the tongue in a single dose rather than sitting in one spot. Two sprays a day at home, no needles and no clinic visits, from $25 a month with no consultation fee and no insurance needed.

Which one is right for you depends on your allergy history and what your allergist recommends. If you are already doing well on allergy shots for pet dander, there is no reason to switch. OLLEREG exists for the people who will not start shots because of the needles, the clinic time, or the cost.

Frequently Asked Questions

Does OLLEREG work for both dog AND cat allergies? +

Yes. The pet dander spray is formulated to address the most common allergens from both dogs and cats. Whether you have one pet or a houseful, the same spray builds tolerance to the dander proteins that trigger your symptoms.

Can I stop taking antihistamines once I start OLLEREG? +

You can continue using antihistamines as needed while starting OLLEREG. As your tolerance builds over weeks and months, many patients find they rely on them less and less. OLLEREG addresses the root cause, not just the symptoms.

What if it doesn't work for me? +

OLLEREG comes with a 90-day money-back guarantee. Use it consistently for 90 days, and if you're not satisfied, we'll refund you in full. No hassle, no questions.

Is it safe for my child? +

Yes. OLLEREG is safe for patients as young as 3 years old. A parent or guardian must complete the health check after purchase and supervise each dose.

I'm allergic to my cat. What are my actual options? +

There are four. Avoidance, which for most people means rehoming the cat. Antihistamines like Zyrtec or Claritin, which manage symptoms while you keep taking them. Cat allergy shots at an allergist's office, which are effective but mean needles, a clinic schedule and usually $1,500 to $4,000 a year. And at-home immunotherapy, either sublingual drops or OLLEREG's whole-mouth spray, which builds tolerance to cat dander without needles or clinic visits, from $25 a month. See the full comparison above.

Is OLLEREG the same thing as cat or dog allergy drops? +

Same science, different delivery. Allergy drops are sublingual immunotherapy: liquid extract placed under the tongue. OLLEREG is Oromucosal Immunotherapy, a spray that reaches your cheeks, gums and under the tongue in one dose instead of sitting in a single spot. Both work with your immune system rather than blocking symptoms the way an antihistamine does. If you have been pricing pet allergy drops, OLLEREG starts at $25 a month with no consultation fee, where most drop services run $50 to $89 a month plus a consultation.

Do I have to give up my cat or dog? +

No. That is the whole point. OLLEREG is for people who have already decided the pet is staying and need a way to live with the dander. You keep the animal, you keep your routine, and you take two sprays a day.

Does insurance cover pet allergy treatment? +

Allergy shots are often partially covered, though you will still owe copays for every visit across the build-up and maintenance phases. At-home immunotherapy, including allergy drops and OLLEREG, is generally not covered by insurance and is paid out of pocket. OLLEREG is a flat $25 a month with no consultation fee, no sign-up fee and no insurance paperwork, so the out-of-pocket number is the number.

Does OLLEREG cover food allergies? +

No. OLLEREG covers environmental allergens only: pet dander, pollen, dust mites and mold. It does not cover food, latex, medication or insect sting allergies. For any of those, see an allergist in person.
