@cila and @raney MAYBE it is covered. My current insurer, BCBS Federal, and my former local insurer, by practice, do not include in their prescription formulary any drug in the form and dosage that is available over the counter. If you need a special (usually higher) dosage, or a special form (like suppository or sublingual drops) not available OTC they will cover, often as a specialtyndrug at high cost. Most Medicare supplements have the same policy.

Once my pulmonologist wrote a scrip and Walgreens filled it for my routine copay. They later notified me BCBS declined, and I was billed the difference between the copay and the retail price.
