Still Relying on Allergy Pills and Shots for Cat Allergies? Here's What They Don't Address.

For years, people with cat allergies have mainly had two options: reach for an antihistamine when symptoms show up, or commit to a longer-term course of allergy shots.

But neither is designed to directly reduce the amount of cat allergen in your everyday environment. 3-min read

The Trade-Off With Allergy Pills

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

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.

What If You Could Target the Allergen Instead?

That's the idea behind Pacagen.

Rather than focusing only on how your body reacts, Pacagen is designed to help reduce exposure to Fel d 1, the major cat allergen.

And because cat allergens start with the cat and then spread into the home, Pacagen approaches the problem from two directions.

“It’s helping!”

After giving the supplement to our cats for over a month, we are noticing less allergy symptoms in multiple people in our house. So thankful we found this! I prefer this cat supplement over allergy shots for people.

“Works really well!”

I have three cats and used to get allergy shots on a regular basis. My schedule got too busy, so I was just suffering along with a stuff nose and itchy skin. My cats are also incredibly picky and manage to avoid most food supplements I add. This spray works so well!

Catherine B.Verified Customer

“Miracle worker!”

My husband has such bad cat allergies. He has had to take Zyrtec daily for his allergies to be bearable but even then he’s still miserable every night. Came across this product and went down the rabbit hole of cat allergens, what causes them and how this product works.

Lexie C.Verified Customer

“3 Years of Allergy Shots Later...”

After 3 years of allergy shots, we both still struggle with our cat allergies and this is the only thing keeping us from sneezing up a literal storm. This is a thousand percent not a placebo effect topper.

Katie K.Verified Customer

“This stuff really works!!”

I adopted my cat over a year ago and was struggling for the first 3 weeks while giving my cat the Pacagen food topper. But after the three weeks I stopped needing allergy pills and I can now snuggle with my cat without sneezing or feeling itchy!

ChelseaVerified Customer

“Happy Son!”

I bought this product because my son is allergic to cats and he felt awful when he came to my home. Sneezes, tissues and allergy pills were constant during his visits. I used the spray before and during my son's visit and no sneezing at all in two days!
