Frequently Asked Questions

Will OLLEREG help with dust mite allergies? +

Yes. The indoor allergen spray specifically targets dust mite allergens, which are the #1 cause of year-round allergy symptoms. OLLEREG uses Oromucosal Immunotherapy (OMIT) to retrain your immune response so your body stops overreacting to these triggers.

How long until I notice a difference? +

Most patients notice improvement within 3-6 months. Unlike air purifiers or antihistamines that manage the environment or mask symptoms, OLLEREG changes how your immune system responds. Full treatment course is 3 years for lasting results.

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 to work — and we're confident in the science behind it.

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 rare — and our post-purchase health check ensures OLLEREG is right for you before we ship.
