Discontinue immediately if reaction occurs and implement appropriate care measures.

Lab Test Considerations:

Monitor hepatic function prior to and periodically during therapy. May cause ↑AST.

Implementation ⬆ ⬇

With dry hands, apply rounded side of tablet to upper gum region, just above the incisor tooth. Hold tablet in place (with light pressure) over upper lip for 30 seconds to ensure adhesion. If tablet does not adhere or falls off within 6 hr, reposition immediately or replace with a new tablet if adhesion fails on repositioning. If tablet is swallowed within 6 hr of placement, drink a full glass of water and apply a new tablet; if tablet falls off or is swallowed after 6 hr from initial placement, wait to apply a new tablet until the next regularly scheduled dose. Alternate side of mouth with each tablet placement; clear away remains of old tablet before placing another tablet. DNC: Do not crush, chew, or swallow tablets. May take food or drink normally; avoid chewing gum.

Patient/Family Teaching ⬆ ⬇

Explain purpose and side effects of medication to patient. Advise patient to read Patient Information before starting therapy. Instruct patient to take as directed. Describe application and what to do if tablet falls off or is swallowed.
Advise patient of allergic and hypersensitivity reactions. If they occur, notify a health care professional immediately and seek emergent medical attention if needed.
Advise patient to notify a health care professional of milk allergies before starting treatment.
