What to say at the pharmacy

“Can you fill my Brethine prescription with the authorized generic from ANI Pharmaceuticals? The NDC is [your strength’s NDC]. Could you check the price and whether my plan covers it?”

Pick your strength above and your NDC will appear here.

Good to know

It may look different from Brethine (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.
