If you take a lot of prescription medicine, the costs can add up, even if you have prescription drug coverage. Mail order prescriptions are often a good way to save money. Our insurance carrier works with a prescription service that gives us three months of medicine for the price of two co-pays instead of three.
Another way to save money is to ask your doctor to write your prescription for twice the dosage that you normally take, and then split the pill, taking only half of it at a time. Larger dosages typically cost less. There are a couple of caveats with this approach though. Not all pills can be safely split. Your doctor may not feel comfortable doing this. You must make sure that you don’t accidentally take the whole pill.
