How the 11-digit form is made: The package segment has 1 digit, so one leading zero is added to it (5-4-1 → 5-4-2). Formatting the NDC does not by itself make it billable — the product, package and quantity must match what was dispensed or administered, and payer rules apply. Conversion rules

Indications (excerpt from the label)

1. Indications and Usage Section 1 INDICATIONS AND USAGE Tizanidine tablet is a central alpha-2-adrenergic agonist indicated for the management of spasticity. Because of the short duration of therapeutic effect, treatment with tizanidine tablets should be reserved for those daily activities and times when relief of spasticity is most important [see Dosage and Administration (2.1)].
