Important Safety Information about GRASTEK

GRASTEK can cause severe allergic reactions that may be life-threatening. Stop taking GRASTEK and get medical treatment right away if you or your child has any of the following symptoms after taking GRASTEK:
- 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
Do not take GRASTEK if you or your child has severe, unstable or uncontrolled asthma; had a severe allergic reaction in the past that included trouble breathing, dizziness or fainting, or rapid or weak heartbeat; had difficulty with breathing due to swelling of the throat or upper airway after using any sublingual immunotherapy before; has ever been diagnosed with eosinophilic esophagitis; or is allergic to any of the inactive ingredients contained in GRASTEK.
For home administration of GRASTEK, your doctor will prescribe auto-injectable epinephrine, a medicine you can inject if you or your child has a severe allergic reaction after taking GRASTEK. Talk to your doctor or read the epinephrine patient information if you have any questions about the use of auto-injectable epinephrine.
The first dose of GRASTEK must be taken in the doctor’s office. After taking the first tablet, you or your child will be watched for at least 30 minutes for symptoms of a serious allergic reaction.
Children should be given each tablet of GRASTEK by an adult who will watch for any symptoms of a serious allergic reaction.
You should tell your doctor if you or your child is taking or has recently taken any other medicines, including medicines obtained without a prescription and herbal supplements. Keep a list of them and show it to your doctor and pharmacist each time you get a new supply of GRASTEK. Ask your doctor or pharmacist for advice before taking GRASTEK.
Stop GRASTEK and contact your doctor if you or your child has any of the following after taking GRASTEK:
Any type of a serious allergic reaction; throat tightness that worsens or swelling of the tongue or throat that causes trouble speaking, breathing or swallowing; asthma or any other breathing condition that gets worse or heartburn, difficulty swallowing, pain with swallowing, or chest pain that does not go away or worsens. Also stop taking GRASTEK following mouth surgery procedures (such as tooth removal) or if you or your child develop any mouth infections, ulcers or cuts in the mouth or throat.
The most commonly reported side effects were itching of the mouth, lips, or tongue, swelling under the tongue, or throat irritation. These side effects, by themselves, were not dangerous or life-threatening.
Your doctor may decide that GRASTEK is not the best treatment for you or your child if you or your child has asthma; plan to become pregnant or is breast-feeding; is unable or unwilling to administer epinephrine; or is taking certain medicines, including other allergen immunotherapy.

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.

Please read the accompanying Medication Guide for GRASTEK, including the information about severe allergic reactions, and discuss it with the doctor. The physician Prescribing Information also is available.

GRASTEK® (Timothy Grass Pollen Allergen Extract) is a daily dose of immunotherapy

Immunotherapy is designed to repeatedly expose your body to small amounts of an allergen. That’s why it’s important to take GRASTEK every day, as your allergy specialist prescribes, even when you don’t have symptoms.

Taking the first tablet in your allergy specialist’s office

The first dose of GRASTEK must be taken in the allergy specialist’s office. After taking the first dose, you or your child will be observed for at least 30 minutes by a healthcare professional for symptoms of a serious allergic reaction. If the first dose is well tolerated, you can continue to take your GRASTEK once a day at home. Children should always take GRASTEK under the supervision of an adult.
