Good to know

It may look different from Fosrenol (color, shape, or markings). That’s normal for an authorized generic.
If your prescription says “dispense as written,” the pharmacy needs your prescriber’s OK to give you the authorized generic.
Cash prices can differ a lot from one pharmacy to the next, so it can pay to ask two. With insurance, what you pay depends on your plan.
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.

Prices change: confirm with the pharmacy before you fill. drugalt.com/drug/fosrenol/
