Still have questions?

That’s great, we’ve got answers.

Use your searchRx discount card at pharmacies nationwide, from the large chains to small independent pharmacies.

Because searchRx isn’t insurance, there is no program or membership to enroll in. Once you receive your card, just show it to your pharmacist and start saving on your prescription medications.

Yes, of course! Our card is not insurance, we simply provide discounts on prescriptions. Because pricing is an ongoing negotiation, please bring both your insurance card and searchRx coupon to your pharmacist to see which provides a more cost-effective option for you.

No. As mentioned previously, we are not a replacement for insurance. We merely provide discounts through coupons for prescriptions. Any purchases through searchRx will not count toward an insurance deductible.
