A prescription may be written for a 90 day supply, but insurance companies often have quantity limits on how much they will offer coverage on at one time.
This is usually the case for medications that can be dangerous if overused or are only FDA-approved for a short period of time.
We will always fulfill a larger quantity if we are able to! If you believe that you should have received a larger quantity, you are welcome to reach out so that we can offer some clarity.
