Before: Constant sneezing, watery eyes, and misery every spring and fall. OTC meds barely helped.

Frequently Asked Questions

Will OLLEREG help with cedar fever specifically? +

Yes. OLLEREG's seasonal sprays include formulations targeting mountain cedar, one of the worst allergens in Texas. OLLEREG uses Oromucosal Immunotherapy (OMIT) to retrain your immune response to cedar pollen over time, reducing severity each season instead of just masking symptoms.

How is this different from Zyrtec or Flonase? +

Antihistamines and nasal steroids temporarily block symptoms but do nothing to change your immune response. OLLEREG is immunotherapy — it gradually retrains your immune system so your body stops overreacting to pollen in the first place. It's a treatment, not a band-aid.

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.
