Prescriptions: Why They Seem So Complicated 

Information to help you and your family

Getting a prescription filled is usually easy. But because of the high cost of prescription medicines, most insurance companies and employers are trying to control drug costs. Some of the things they are doing make getting a prescription more complicated for you and your doctor, and some of the terms they use can be confusing.

What is a formulary?
A formulary is a list of medications that your insurance company will help you pay for. This list is reviewed and changed by the insurance company every few months.

The drugs in a formulary are often listed in two or more groups, depending on how much of the cost you are expected to pay. The amount you're expected to pay is called your co-pay. A typical formulary might include the following groups (also called levels or tiers):


Group Drugs Co-pay size
Level 1 Generic drugs $
Level 2 "Preferred" $$
Level 3 "Non-preferred" brand-name drugs $$$

The more dollar signs in the table, the higher the co-pay amount.

What's the difference between a brand-name drug and a generic drug?
When a drug company develops a new drug, it gives it a brand name. Brand names are the names you usually see in ads on TV and in magazines ­ names like Claritin and Advil.

For several years after the drug is developed, laws prevent other drug companies from copying it. When other companies start manufacturing and selling the drug, their versions are usually known by a different name ­ the generic name. This is often the chemical name. For instance, the generic name of Claritin is loratadine and the generic name of Advil is ibuprofen.

Generic drugs are chemically the same as brand-name drugs, and they are often less expensive. That's why many insurance plans encourage you to use generic drugs.

What are preferred and non-preferred drugs?  What about pharmaceutical mail-order warehouses?
Often two brand-name drugs are useful for the same problem. Your insurance company may be able to get one less expensively than the other. That drug becomes a preferred drug, and the other becomes non-preferred. That's usually why you pay more for non-preferred drugs.

Sometimes an insurance company will move a drug from the preferred list to the non-preferred list. If this happens to you, your doctor might be able to prescribe a preferred drug that would cost you less money and work just as well for you. 

You may use a mail order pharmaceutical warehouse.  This can save you a lot of the cost of the medication by doing so.  However, our office does not respond to faxes or calls from pharmaceutical warehouses for changes to alternative medications since we have already chosen the best medication for you.  If you want to discuss a change, we will be happy to consider this change since our commitment is to you, our patient.  Since we have drugs costs in our electronic charting system, we will be happy to compare costs with you.   Additionally, changes in medications suggested by pharmaceutical warehouses may cause drug-to-drug interactions and these pharmaceutical  warehouses may not be aware of your conditions or other medications you may be on.

What about drugs that aren't in the formulary?
Formularies include a limited number of drugs. Many don't include drugs that the insurance companies believe aren't necessary to improve health. These are sometimes called lifestyle drugs. Weight loss and hair growth drugs are examples of lifestyle drugs. Your insurance company won't help you pay for a drug that isn't part of its formulary.
