Placing the rounded side of the tablet against the gum may be more comfortable. Alternate sides of the mouth with each application; do not crush, chew, or swallow. Avoid chewing gum while in place.
If the tablet does not adhere to the gum or falls off within 6 hours of application, the same tablet should be repositioned immediately. If the tablet does not adhere, use a new tablet.

If the tablet falls off or is swallowed >6 hours after application, a new tablet should not be applied until the next regularly scheduled dose.

Concerns related to adverse effects:
• Hypersensitivity reactions: Hypersensitivity reactions (including anaphylactic reactions) have been reported. There is no information regarding cross-reactivity between miconazole and other azole antifungals. Monitor patients with a history of azole hypersensitivity.
• Hepatic impairment: Although systemic absorption is typically minimal, use with caution in patients with hepatic impairment.
Pregnancy Risk Factor
Adverse events were observed in some animal reproduction studies. There is minimal systemic absorption following buccal application.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache, nausea, vomiting, diarrhea, abdominal pain, or change in taste. Have patient report immediately to prescriber application site pain or edema or difficulty swallowing (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
