Mesnex vs. its authorized generic and generics

Mesnex is given by a doctor or nurse and billed by the clinic, not a pharmacy. Your care team and your insurance decide which product you get, so ask them what you’d pay.

Good to know

It may look different from Mesnex (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.
Coverage depends on your plan. Your care team or insurer can tell you what you’d pay.
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/mesnex/
