Oravig: 50 mg [contains corn starch, milk protein concentrate]
Mechanism of Action
Inhibits biosynthesis of ergosterol, damaging the fungal cell wall membrane, which increases permeability causing leaking of nutrients
Duration of Action
Buccal adhesion: 15 hours
Use: Labeled Indications
Treatment of oropharyngeal candidiasis
Hypersensitivity to miconazole, milk protein concentrate, or any component of the formulation
Dosage and Administration
Oropharyngeal candidiasis (mild): Buccal tablet: 50 mg (1 tablet) applied to the upper gum region (canine fossa) once daily for 7 to 14 days (HHS [OI adult 2017]; IDSA [Pappas 2016])
Refer to adult dosing.
Oropharyngeal candidiasis (mild): Adolescents ≥16 years: Refer to adult dosing.
Oral: Apply in the morning after brushing teeth. With dry hands, place either side of the tablet against the upper gum above the incisor tooth; hold with slight pressure over the upper lip for 30 seconds. 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 is swallowed within 6 hours of application, the patient should drink a glass of water and apply a new tablet (only once). 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.
Should be taken whole; do not crush, chew, or swallow. Food and drink can be taken normally; chewing gum should be avoided.
