Postmarketing Reports
Skin and subcutaneous tissue disorders: Erythema
Immune system disorders: Serious systemic allergic reactions, including anaphylaxis
Respiratory, thoracic, and mediastinal disorders: Cough
Warnings
Black Box Warnings
Severe allergic reactions
- Life-threatening allergic reactions, including anaphylaxis and severe laryngopharyngeal restriction, may occur
- Not for administration to patients with severe, unstable, or uncontrolled asthma
- Observe patients for at least 30 min following initial dose
- Prescribe autoinjectable epinephrine; instruct and train patients on appropriate use and instruct patients to seek immediate care upon use
- Administration may not be suitable for patients with certain underlying medical conditions that may reduce the ability to survive serious allergic reactions or for patients unresponsive to epinephrine or inhaled bronchodilators, such as those taking beta-blockers
Contraindications
Severe, unstable, or uncontrolled asthma
History of severe systemic allergic reaction
History of severe local reaction after taking sublingual allergen immunotherapy
History of eosinophilic esophagitis
Hypersensitivity to product or components
Cautions
Therapy may cause systemic allergic reactions, including anaphylaxis, which may be life-threatening (see Black Box warning)
May cause local reaction in mouth or throat that could compromise upper airway; discontinue therapy if patient experiences persistent and escalating adverse reactions in mouth or throat
Eosinophilic esophagitis may occur; discontinue therapy and consider diagnosis of eosinophilic esophagitis in patients who experience persistent gastroesophageal symptoms including dysphagia or chest pain
Withhold immunotherapy if patient experiences acute asthma exacerbation; reevaluate patients who experience recurrent asthma exacerbations; discontinue therapy if necessary
Concomitant dosing with other allergen immunotherapy may increase likelihood of local or systemic adverse reactions to either subcutaneous or sublingual allergen immunotherapy
Stop therapy and allow complete healing of oral cavity in patients with oral inflammation, including oral lichen planus, mouth ulcers or thrush, or oral wounds such as those following oral surgery or dental extraction
Drug interactions overview
- Patients taking beta-adrenergic blockers may be unresponsive to usual doses of epinephrine used to treat serious systemic reactions, including anaphylaxis; beta-adrenergic blockers may antagonize cardiostimulating and bronchodilating effects of epinephrine
- Patients taking alpha-adrenergic blockers may be unresponsive to usual doses of epinephrine used to treat serious systemic reactions, including anaphylaxis; alpha-adrenergic blockers may antagonize vasoconstricting and hypertensive effects of epinephrine; ergot alkaloids may also reverse pressor effects of epinephrine
- Adverse effects of epinephrine may be potentiated in patients taking tricyclic antidepressants, levothyroxine sodium, monoamine oxidase inhibitors, and the antihistamines chlorpheniramine and diphenhydramine
- Patients who receive epinephrine while taking cardiac glycosides or diuretics should be observed carefully for development of cardiac arrhythmias
Pregnancy
Pregnancy
Available data on pregnant women are insufficient to inform associated risks in pregnancy
Animal studies
- In a fetal/embryo developmental toxicity study performed in mice, administration during gestation did not reveal adverse developmental outcomes in fetuses
Lactation
Data are not available to assess effects on breastfed children or on milk production and excretion in nursing women
Consider developmental and health benefits of breastfeeding along with the mother’s clinical need for drug and any potential adverse effects on breastfed infant from drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Mechanisms of action of allergen immunotherapy have not been fully established
Administration
Sublingual Administration
Remove foil from blister with dry hands
Place tablet under tongue; it will dissolve within 10 sec; do not swallow for at least 1 min
Wash hands after handling tablet
Not for administration with food or beverage; do not take food or beverage for 5 min after taking tablet
Administer first dose under the supervision of a physician with experience in the diagnosis and treatment of allergic reactions; observe patient for at least 30 minutes following initial dose; if patient tolerates first dose, subsequent doses may be taken at home
Prescribe autoinjectable epinephrine to patients and instruct them in proper use of emergency self-injection of epinephrine
Missed dose
- Limited data are available regarding the safety of restarting treatment after a missed dose
- In clinical studies, treatment interruptions for up to 7 days were allowed
Storage
Store at controlled room temperature, 20-25ºC (68-77ºF); store in original package until use to protect from moisture
