How It Works

Real Allergy Treatment — Without Drugs

OLLEREG uses immunotherapy — the same science behind allergy shots, used globally for over 30 years. Instead of suppressing symptoms with chemicals, it works with your body to build lasting tolerance.

Allergen Extracts

Each spray contains the same proteins found in pollen, pet dander, or dust mites — the same allergen proteins used by allergists worldwide.

Tiny Doses, Under the Tongue

Two sprays a day deliver controlled microdoses to immune cells under your tongue. Takes less than 60 seconds.

Your Immune System Relearns

Over weeks and months, your body builds tolerance. Allergy symptoms decrease as the immune system stops overreacting.

"I wanted something that wasn't just another pill. OLLEREG actually treats the problem. A few months in and I barely notice allergy season anymore."

Before: Tried honey, neti pots, and every OTC med. Nothing lasted.

Before: Daily antihistamines for years. Tired of the side effects and the cycle.

Frequently Asked Questions

Is OLLEREG really drug-free? +

Yes. OLLEREG contains allergen extracts — the same proteins found in pollen, pet dander, and dust mites, delivered in tiny, controlled doses. There are no synthetic drugs, steroids, or antihistamines. It works with your immune system, the same way allergy shots have for over a century — just without the needles or clinic visits.

How is this different from natural remedies like honey or supplements? +

Local honey, herbal supplements, and other home remedies have limited or no clinical evidence for treating allergies. OLLEREG uses Oromucosal Immunotherapy (OMIT) — the same medical approach used by allergists worldwide for decades, backed by hundreds of clinical studies. The difference is that immunotherapy actually changes your immune response over time, while home remedies only provide temporary or placebo relief.

What are the allergen extracts made from? +

The extracts are derived from the actual allergens — pollen, animal dander, dust mites, mold spores. They're the same clinical-grade extracts used by allergists for allergy shots. The only difference is delivery: under the tongue instead of via injection.

How long until I notice results? +

Most patients begin noticing improvement within 3–6 months of consistent daily use. Immunotherapy works gradually — your immune system needs time to retrain. That's why we offer a 90-day money-back guarantee. About 80% of patients see meaningful long-term relief.

Are there side effects? +

The most common side effect is mild mouth or throat itching in the first few weeks, which typically subsides as your body adjusts. Serious reactions are extremely rare with Oromucosal Immunotherapy (OMIT) — clinical trials involving thousands of patients report significantly fewer adverse events than allergy shots.

Do I need to see a separate doctor or use insurance? +

OLLEREG includes a quick health review with our board-certified allergist, Dr. Dat Tran, MD, FAAAAI, before your first shipment — everything handled in one streamlined intake, no separate doctor visit required. No insurance needed, and you may be able to use HSA or FSA funds — check with your plan administrator.

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. We offer this because immunotherapy takes time — and we're confident in the science behind it.
