Selected Important Safety Information about ODACTRA

What is the most important information I should know about ODACTRA?
ODACTRA can cause severe allergic reactions that may be life-threatening. If any of these symptoms occur, stop taking ODACTRA and immediately seek medical care:

  • Trouble breathing
  • Throat tightness or swelling
  • Trouble swallowing or speaking
  • Dizziness or fainting
  • Rapid or weak heartbeat
  • Severe stomach cramps or pain, vomiting, or diarrhea
  • Severe flushing or itching of the skin

For home administration of ODACTRA, your doctor should prescribe auto-injectable epinephrine to treat a severe reaction, should one occur. Your doctor will train and instruct you on the proper use of auto-injectable epinephrine.

If you forget to take ODACTRA, do not take two tablets. Take the next tablet at your normal scheduled time the next day. If you miss more than one tablet of ODACTRA, contact your doctor before restarting.

Do not take ODACTRA if:

  • You have severe, unstable or uncontrolled asthma
  • You had a severe allergic reaction in the past that included any of these symptoms: trouble breathing, dizziness or fainting, rapid or weak heartbeat
  • You have ever had difficulty with breathing due to swelling of the throat or upper airway after using any sublingual immunotherapy before
  • You have ever been diagnosed with eosinophilic esophagitis
  • You are allergic to any of the inactive ingredients in ODACTRA

Your doctor may decide that ODACTRA is not the best treatment if:

  • You have asthma, depending on how severe it is
  • You suffer from lung disease such as chronic obstructive pulmonary disease (COPD)
  • You suffer from heart disease such as coronary artery disease, an irregular heart rhythm, or you have hypertension that is not well controlled
  • You are pregnant, plan to become pregnant during the time you will be taking ODACTRA, or are breast-feeding
  • You are unable or unwilling to administer auto-injectable epinephrine to treat a severe allergic reaction to ODACTRA
  • You are taking certain medicines that enhance the likelihood of a severe reaction, or interfere with the treatment of a severe reaction. These medicines include:
    • Beta blockers and alpha-blockers (prescribed for high blood pressure)
    • Cardiac glycosides (prescribed for heart failure or problems with heart rhythm)
    • Diuretics (prescribed for heart conditions and high blood pressure)
    • Ergot alkaloids (prescribed for migraine headache)
    • Monoamine oxidase inhibitors or tricyclic antidepressants (prescribed for depression)
    • Thyroid hormone (prescribed for low thyroid activity)
  • If you are receiving allergy shots or other immunotherapy under the tongue. Use of more than one of these types of medicines together may increase the likelihood of a severe allergic reaction

Stop taking ODACTRA and contact your doctor if you have any mouth surgery procedures (such as tooth removal), develop any mouth infections, ulcers or cuts in the mouth or throat, or have heartburn, difficulty swallowing, pain with swallowing, or chest pain that does not go away or worsens.

The most commonly reported side effects were throat irritation/tickle, itching in the mouth or ears, swelling of the back of the mouth, lips or tongue. These side effects, by themselves, are generally not dangerous or life-threatening.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
