What to say at the pharmacy

“Can you fill my EC-Naprosyn prescription with the authorized generic from Zameer Pharmaceuticals? The NDC is 90096-161-01. Could you check the price and whether my plan covers it?”

Good to know

It may look different from EC-Naprosyn (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.
