GastroGard price breakdown
Typical 30-day supply pricing (chronic medications). Actual bid ranges vary by ZIP + pharmacy.
What drives GastroGard pricing?
Same medication, wildly different prices — here's why.
Distribution channel
Vet offices carry retail markup — often 40-60% above pharmacy dispensing cost. Same manufacturer, same medication, but a fundamentally different distribution model.
Pharmacy competition
In a vacuum, a pharmacy sets one price. When pharmacies bid against each other for the same prescription, they price against competitors — that's the Script Unlock lever.
Volume + geography
Pharmacies in dense metros with high proton pump inhibitor volume have lower cost bases + bid more aggressively. Rural pharmacies often bid competitively to win volume they can't get locally.
Brand vs generic
Generic omeprazole (paste) is often 40-60% cheaper than brand GastroGard. Ask your vet if generic substitution is clinically appropriate.
Quantity dispensed
90-day supplies typically cost 15-30% less per unit than 30-day. Ask your vet if a 90-day prescription is clinically appropriate for your horse's condition.
Time of month + season
Pharmacies with excess inventory bid more aggressively. Manufacturer rebate cycles + seasonal demand shifts (flea/tick season, allergy season) affect competitive intent.
Frequently asked questions about GastroGard pricing
How much does GastroGard cost for horses in 2026?↓
GastroGard for horses typically costs ~$38 at vet offices (30-day supply) and ~$25 through verified Script Unlock pharmacies. That's a savings of $13 per fill (34%). For chronic prescriptions filled monthly, that's ~$156/year.
Why is GastroGard cheaper at Script Unlock than at the vet?↓
Vet offices carry high overhead — clinical staff, exam room space, retail markup. When pharmacies compete for your prescription, they price against each other, not against your relationship with the vet. Same proton pump inhibitor, same manufacturer, different distribution channel.
Do I need pet insurance to save on GastroGard?↓
No. Script Unlock is a cash-pay marketplace. Verified pharmacies bid competitive cash prices — often less than what pet insurance would cover after your deductible. For routine chronic prescriptions like GastroGard, cash-pay through Script Unlock typically beats insurance.
Are GastroGard prices the same across every pharmacy?↓
No — this is exactly why Script Unlock exists. The same GastroGard prescription can vary $10-$38 between pharmacies. Location, volume, contracts, competitive intent — all drive pricing. Bidding surfaces the low price for your ZIP.
Does the cost of GastroGard include shipping?↓
Winning bids on Script Unlock include shipping cost upfront (or specify pickup). You see the total price you'll pay before you commit. No surprise fees at checkout, no hidden shipping markups.
Can I save more on GastroGard by buying larger quantities?↓
Often yes. Ask your vet to write a 90-day prescription instead of 30-day for chronic medications. Many pharmacies offer bulk discounts. Script Unlock pharmacies typically bid 5-15% additional discount on 90-day quantities. Ask your vet if a 90-day supply is clinically appropriate for your horse.
