RAGWITEK™ (Short Ragweed Pollen Allergen Extract) --

 GRASTEK® (Timothy Grass Pollen Allergen Extract): top of page


WARNING: SEVERE ALLERGIC REACTIONS
  • GRASTEK can cause life-threatening allergic reactions such as anaphylaxis and severe laryngopharyngeal restriction.
  • Do not administer GRASTEK to patients with severe, unstable or uncontrolled asthma.
  • Observe patients in the office for at least 30 minutes following the initial dose.
  • Prescribe auto-injectable epinephrine, instruct and train patients on its appropriate use, and instruct patients to seek immediate medical care upon its use.
  • GRASTEK may not be suitable for patients with certain underlying medical conditions that may reduce their ability to survive a serious allergic reaction.
  • GRASTEK may not be suitable for patients who may be unresponsive to epinephrine or inhaled bronchodilators, such as those taking beta-blockers.



INDICATIONS AND USAGE:
GRASTEK® is an allergen extract indicated as immunotherapy for the treatment of grass pollen-induced allergic rhinitis with or without conjunctivitis confirmed by positive skin test or in vitro testing for pollen-specific IgE antibodies for Timothy grass or cross-reactive grass pollens. GRASTEK is approved for use in persons 5 through 65 years of age.

GRASTEK is not indicated for the immediate relief of allergic symptoms.

DOSAGE AND ADMINISTRATION:
 For sublingual use only.
Dose:  One GRASTEK tablet daily.

Administration:
Administer the first dose of GRASTEK in a healthcare setting under the supervision of a physician with experience in the diagnosis and treatment of allergic diseases. After receiving the first dose of GRASTEK, observe the patient for at least 30 minutes to monitor for signs or symptoms of a severe systemic or a severe local allergic reaction. If the patient tolerates the first dose, the patient may take subsequent doses at home.
  • Administer GRASTEK to children under adult supervision.
  • Take the tablet from the blister unit after carefully removing the foil with dry hands.
  • Place the tablet immediately under the tongue. Allow it to remain there until completely dissolved. Do not swallow for at least 1 minute.
  • Wash hands after handling the tablet.
  • Do not take the tablet with food or beverage. Food or beverage should not be taken for the following 5 minutes after taking the tablet.
Initiate treatment at least 12 weeks before the expected onset of each grass pollen season and continue treatment throughout the season. For sustained effectiveness for one grass pollen season after cessation of treatment, GRASTEK may be taken daily for three consecutive years (including the intervals between the grass pollen seasons). The safety and efficacy of initiating treatment in season have not been established.

Data regarding the safety of restarting treatment after missing a dose of GRASTEK are limited. In the clinical trials, treatment interruptions for up to seven days were allowed.

Prescribe auto-injectable epinephrine to patients prescribed GRASTEK and instruct them in the proper use of emergency self-injection of epinephrine.

CONTRAINDICATIONS: GRASTEK is contraindicated in patients with:
  • Severe, unstable or uncontrolled asthma
  • A history of any severe systemic allergic reaction
  • A history of any severe local reaction after taking any sublingual allergen immunotherapy
  • A history of eosinophilic esophagitis
  • Hypersensitivity to any of the inactive ingredients [gelatin, mannitol and sodium hydroxide] contained in this product
WARNINGS AND PRECAUTIONS:
Inform patients of the signs and symptoms of serious allergic reactions and instruct them to seek immediate medical care and discontinue therapy should any of these occur.

In case of oral inflammation or wounds, stop treatment with GRASTEK to allow complete healing of the oral cavity.

ADVERSE REACTIONS:
Adverse reactions reported in geq5% of patients were: ear pruritus, oral pruritus, tongue pruritus, mouth edema, throat irritation.

To report SUSPECTED ADVERSE REACTIONS, contact Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., at 1-877-888-4231 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

See package insert for PATIENT COUNSELING INFORMATION and Medication Guide.

USE IN SPECIFIC POPULATIONS:
Pregnancy
Pregnancy Category B: Reproductive and developmental toxicity studies performed in female mice have revealed no evidence of harm to the fetus due to GRASTEK. In these studies, the effect of Timothy grass (Phleum pratense) pollen allergen extract, the active component of GRASTEK, on embryo-fetal development was evaluated. Mice were administered approximately 460,000 BAU/kg/day of Timothy grass pollen allergen extract by oral gavage on days 0 to 15 of gestation. A dose of 460,000 BAU/kg/day of Timothy grass pollen allergen extract corresponds to approximately 8,200-fold a human dose on a BAU/kg/day basis. No adverse effects on embryo-fetal development were observed. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, GRASTEK should be used during pregnancy only if clearly needed.

Because systemic and local adverse reactions with immunotherapy may be poorly tolerated during pregnancy, GRASTEK should be used during pregnancy only if clearly needed.

Nursing Mothers
It is not known if GRASTEK is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when GRASTEK is administered to a nursing woman.

Pediatric Use
Efficacy and safety of GRASTEK have been established in children and adolescents 5 through 17 years of age.

The safety and efficacy in pediatric patients below 5 years of age have not been established.

Geriatric Use
There is no clinical trial experience with GRASTEK in patients over 65 years of age.

DOSAGE FORMS AND STRENGTHS:
GRASTEK is available as 2800 Bioequivalent Allergy Unit (BAU) tablets that are white to off-white, circular with a debossed round detail on one side.
