Compounded Omeprazole for Pets
Horses with equine gastric ulcer syndrome can spend $200+/month on FDA-approved GastroGard. Compounded equine omeprazole at 4 mg/kg/day provides equivalent acid suppression at a fraction of the cost. Cats benefit from compounded flavored liquid.
Why Chewy Pharmacy can't fulfil this prescription
Chewy stocks commercial GastroGard for horses (full retail) and human omeprazole capsules. No equine-strength compounded paste at the actual horse dose Chewy delivers.

Species-specific benefit
GastroGard at $7–9 per syringe dosed daily is unsustainable for many horse owners. Compounded equine omeprazole at $1–2 per dose provides equivalent ulcer treatment.
Cats with chronic vomiting or gastric ulceration benefit from compounded fish-flavored liquid for ongoing acid suppression.
