Medicare
We don’t know yet
No Medicare reference price. Part D: The Part D file flags this drug’s average spending per dosage unit as an outlier, so OpenBill does not use it as a reference price. Part B: This NDC is not in the current quarter’s Medicare Part B NDC-HCPCS crosswalk, so it has no Part B payment limit.
The spread
We don’t know yet
There is no Medicare figure to compare with, so there is no spread.
Cost-plus estimate
$158.85 estimated
$133.78 + $20.07 (15%) + $5.00 fee per fill = $158.85

What to ask at the counter
None of these figures is your price: what you pay depends on your pharmacy, your insurance, coupons and discounts.
- What is your cash price for 30 tablets? Is it lower than what I would pay through my insurance?
- Is a generic version available, and would it suit me? NADAC lists a generic with the same ingredient, strength and dosage form by FDA: IVERMECTIN 3 MG TABLET. Ask your pharmacist or prescriber; do not switch on your own.
- These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
