Formula 44: Proven Results & Real Relief

The Original Problem Solver

FORMULA 44

Formula 44 is an ointment that forms a protective, moisturizing barrier, designed to withstand daily encounters with muck, whether in the stall, pasture, or arena—something that traditional lotions or creams simply cannot do.

The Apothecary Tradition

Historically, an apothecary was much more than a retail pharmacy. These early pharmacists were experts in selecting and preparing treatments for their patients, often working directly with medical practitioners. Dr. Hansen’s Equine Apothecary draws on this rich tradition—bringing together deep pharmaceutical expertise with a hands-on understanding of horses to create remedies that are tailored for practical, everyday use in the equestrian world.

"I had been battling rain rot and scratches on my OTTB for over a month with no success. I tried 5 different options and nothing was making any difference. At my wits end, I decided to give Dr. Hansen’s Formula 44 a try. Three days with Formula 44 is all it took to clear up an issue I’d been dealing with for over a month! I’m not sure what magic she puts in her jars, but my tack room will now never be without it!"

Our mare sustained a nasty skin wound on the inside of her hock while in the pasture.  We used the Formula 44 ointment on the wound, which not only helped it heal but also prevented scarring.  We also used this product for cannon crud and tail rubbing and it worked amazingly well. It smells great too!  Highly recommended!

"I have been using both the spray and the ointment for about 2 weeks on my sensitive chestnut who struggles with crud on hind legs and crusty elbows. These products are definitely now a staple in our grooming box! I used the spray on the hind leg crud consistently after riding and it cleared it up completely within a week. The ointment I use about every other day on his chapped and flaky elbows is also completely resolved and moisturized! I love how the ointment provides a protective barrier to keep moisture locked in for those dry areas or places that have scabbed up. Highly recommend!"

"I was at Equine Affaire and just saw the before and after picture of the Paint and knew I had to give it a try! Very happy with round 1 results! Looking forward to trying the pre-soak method for my boy’s tough stains but overall this worked great first go!"

"My mare has always had pretty bad crud on her hind cannons. Within one use you could see and feel the difference. Absolutely blown away. So glad I came across this product!"

"I purchased the cream from the Blue Lakes Tack Sale in March and I love it, it has taken care of minor skin irritations in one application - I need more!"

Meet Dr. Kristen Hansen

My journey began in 2014, blending my passion for horses with my pharmaceutical expertise. Shortly after graduating from a compounding-focused pharmacy school, I developed my first product, Formula 44 Ointment, when an effective equine wound product I relied on became unavailable. As both a Pharmacist and horse owner, I ensure every product I create meets the highest standard of care—because only the best is good enough for our horses and dogs.
