Our most recent US pharmacy data shows a low of roughly $16.45 for Olopatadine Hcl with a standard discount card. That figure moves with dosage and quantity — check the comparison table for the exact combination you need.
Is Olopatadine Hcl (Pataday) available through Cost Plus Drugs?
Yes — Cost Plus Drugs lists Olopatadine Hcl at roughly $4.25 per unit, a published price with no membership card or coupon involved. See the three-price comparison above for how that stacks up against discount-card pharmacies.
What do Canadian pharmacies charge for Olopatadine Hcl (Pataday)?
We found Canadian pricing for Olopatadine Hcl starting near $5.60 per tablet in USD terms. That's before any shipping charge, which the table above breaks out separately.
Why is Olopatadine Hcl (Pataday) priced differently in the US and Canada?
Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the US price is actually the lower of the two once a program like Cost Plus Drugs is factored in — the assumption that Canada is always cheaper doesn't hold for every drug.
Can Medicaid help pay for Olopatadine?
Coverage for OTC drugs like Olopatadine under Medicaid varies significantly by state; some programs may cover it while others do not. Individuals without Medicaid coverage for this medication can often access it at a reduced price by using a pharmacy discount coupon.
What are the brand-name versions of Olopatadine?
Olopatadine is also sold under the brand names Pataday and Retaine Allergy Relief. These are nonprescription eye drops for allergy relief. While brand-name versions generally have a higher retail price than generic Olopatadine, pharmacy discount programs may offer savings on these products as well.
Are there less expensive alternatives to Olopatadine?
Other OTC antihistamine eye drops, such as those containing loratadine (Claritin Eye), epinastine (Elestat), or ketotifen (Alaway, Zaditor), are priced similarly to Olopatadine. For patients with multiple allergy symptoms, oral antihistamines might be a more economical option, though they are generally not recommended if eye symptoms are the sole concern due to potential systemic side effects. Always consult your doctor or pharmacist to determine the best treatment option for your specific needs.
