What to say at the pharmacy

“Can you fill my Firvanq prescription with the authorized generic from Wilshire Pharmaceuticals? The NDC is 52536-104-05. Could you check the price and whether my plan covers it?”

Good to know

It may look different from Firvanq (color, shape, or markings). That’s normal for an authorized generic.
Price and coverage depend on your pharmacy and plan. Ask them to price both the brand and this NDC.
If your pharmacy doesn’t stock it, they can often order it within a day or two.
Don’t stop or change a medicine without talking to your pharmacist or prescriber.
