Fast symptom relief today (OTC options)

• Second‑generation antihistamines (cetirizine/Zyrtec, loratadine/Claritin, fexofenadine/Allegra) help sneezing/itching with fewer sedating effects than diphenhydramine. Antihistamine guidance

• Intranasal steroid sprays (e.g., fluticasone/Flonase, mometasone/Nasonex) reduce nasal inflammation; use daily during exposure. Nasal spray overview

• Saline rinses for mucus and allergen removal. Stuffy nose tips Note: OTCs help symptoms but do not retrain your immune system. Allergy basics

Cleaning and exposure basics that actually help

• Keep the bedroom pet‑free; close doors and use a HEPA air purifier.

• Wash hands after petting; avoid touching eyes/nose.

• Weekly pet bathing and grooming can reduce allergen load substantially. Pet‑allergy tips

• Vacuum with a HEPA filter; remove carpets/curtains where possible; launder bedding in hot water.

• Remember: there are no truly “hypoallergenic” cats; all cats produce Fel d 1 in saliva/skin/urine. Hypoallergenic cat myth

When to test and treat

Consider testing if symptoms persist >2 weeks around cats or indoor exposure. Wyndly’s CLIA‑certified at‑home blood test checks 40+ environmental allergens, including cat dander; results are reviewed by a U.S. board‑certified physician with a personalized plan. At‑Home Allergy Test

Long‑term fix: sublingual immunotherapy (SLIT)

SLIT exposes your immune system to small, precise doses of the cat allergen (Fel d 1) under the tongue to build tolerance and reduce reactions over time. It is clinically proven, needle‑free, and taken at home. Major reviews and societies support SLIT’s safety and effectiveness for environmental allergies. SLIT guide · SLIT vs shots

Is SLIT safe for home use? SLIT has a very favorable safety profile with mostly mild, local side effects; severe reactions are exceedingly rare in published studies. Safety

What if OTCs stop working well? That’s common when exposure is ongoing; SLIT treats the cause, not just symptoms. Why antihistamines may feel weaker
