The Trade-Off With Allergy Pills
Antihistamines can help manage symptoms like sneezing, itching, and a runny nose. But they work on your body’s reaction— not on the cat allergen itself.
That means the allergen can still remain on furniture, bedding, and throughout the home. And depending on the medication, some people may also experience side effects such as drowsiness, dry mouth, or feeling foggy.
The bottom line: relief can be temporary, while the source of exposure stays the same.

And Allergy Shots Require a Bigger Commitment
Allergy shots take a different approach. Instead of managing symptoms, they gradually expose the immune system to allergens over time to help reduce sensitivity.
For some people, that can be an effective long-term option—but it typically requires repeated injections and an ongoing treatment schedule.
The trade-off: it works on your immune response, rather than reducing the cat allergens already present in your environment.
