Matched to this product by name; CMS does not link its files to Open Payments, so a similar name can be a different strength, form or brand. Prescriber counts include only prescribers with 11 or more claims of the drug, because CMS publishes nothing below that. Part D covers drugs dispensed to Medicare beneficiaries at a pharmacy; it does not include drugs given in a clinic or hospital, or patients with other insurance.

Largest prescribers

"No profile" means the prescriber has no Open Payments record here; "None on record" means no payment naming this product in the payment year. Related payments are general payments, and one that names several products is split evenly, so an amount is payments related to the product, not money paid for it. The list is the prescribers with the most claims, up to 100 per drug.

What you are looking at

Manufacturers name the drug, biological or device a payment relates to. CMS does not give products their own identifiers, so a product here is assembled from how it was reported — a brand may appear under more than one spelling, and this page covers one of them rather than the brand as a whole.

Provenance

We reproduce what manufacturers reported. We do not verify, edit or correct the underlying records.

A payment record is not evidence of wrongdoing. Financial relationships between industry and medicine are legal, common and often necessary for research. Who Paid My Doc reports what was disclosed; it does not judge it.
