Good to know

It may look different from Thiola EC (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.
Don’t stop or change a medicine without talking to your pharmacist or prescriber.
