It's no secret that the cost of prescription drugs just keeps going up. Even with health insurance, many patients are still spending large sums at the pharmacy.

But what if there was as way to save $40 on something as simple as allergy medication? Or be able to save $70 on asthma treatment?

Kim Hall would be all for it. The mother of three said her family has good health insurance, but she's still coughing up a lot of cash for medicine.

Hall said she spends a few hundred dollars a month on prescription medication and $200 of that is not covered by her insurance plan.

The rising cost of prescription drugs has pushed up the price of what many pay at the pharmacy. Even with good health coverage, more patients are feeling ill from the sticker shock when they see how much they have to spend on co-payments.

One pharmacist said it's gotten so bad that some patients will actually walk out without their medications because it's just too expensive.

But Channel 4 News has found a new way to offset the rising cost of pills and prescriptions.

We found a Web site called OptimizeRX that offers anyone an assortment of options to save money on prescription drugs.

Hall found a wide range of trial offers on the site, rebates and money-saving coupons. All she had to do was type in an illness or a specific drug, and within seconds she could see if there was a coupon she could use.

According to the Web site, anyone can just print up the coupon, bring it to the pharmacist and then receive the discount, which can be directly deducted from her co-pay.

The discounts range anywhere from $5 up to $70, depending on the drug.

Channel 4 did a little more digging and found not all drugs have coupons, so patients are referred to other similar medications.

Pharmacists want patients to know just because the Web site recommends an alternate drug, doesn't mean it's OK to use.

"The site is not there to teach you which meds are good substitute for one another. It is not simply there to give you a list of discount programs that are out there and available," said pharmacist Mark Boesen.

He recommends patients consult their doctor or pharmacist to make sure it’s OK to switch to a different medication.

The Web site and coupons are all free, but users do need to sign up to receive the savings.
