Important Safety Information and Indication
Contraindications
CAYSTON is contraindicated in patients with a known allergy to aztreonam.
INDICATION
CAYSTON is indicated to improve respiratory symptoms in cystic fibrosis (CF) patients with Pseudomonas aeruginosa (Pa). Safety and effectiveness have not been established in pediatric patients below the age of 7 years, patients with FEV1 <25% or >75% predicted, or patients colonized with Burkholderia cepacia.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of CAYSTON and other antibacterial drugs, CAYSTON should be used only to treat patients with CF known to have Pa in the lungs.
Warnings and Precautions
-
Allergic Reactions: Severe allergic reactions have been reported following administration of aztreonam for injection to patients with no known history of exposure to aztreonam. In addition, allergic reaction with facial rash, facial swelling, and throat tightness was reported with CAYSTON in clinical trials. If an allergic reaction occurs, stop administration of CAYSTON and initiate treatment as appropriate. Caution is advised when administering CAYSTON to patients if they have a history of allergy to beta-lactam antibiotics, such as penicillins, cephalosporins, and/or carbapenems, since cross-reactivity may occur.
-
Bronchospasm: Bronchospasm is a complication associated with nebulized therapies, including CAYSTON. Reduction of 15% or more in forced expiratory volume in 1 second (FEV1) immediately following administration of study medication after pretreatment with a bronchodilator was observed in 3% of patients treated with CAYSTON.
-
Decreases in FEV1 After 28-Day Treatment Cycle: In clinical trials, patients with increases in FEV1 during a 28-day course of CAYSTON were sometimes treated for pulmonary exacerbations when FEV1 declined after the treatment period. Healthcare providers should consider a patient’s baseline FEV1 measured prior to CAYSTON therapy and the presence of other symptoms when evaluating whether post-treatment changes in FEV1 are caused by a pulmonary exacerbation.
-
Development of Drug-Resistant Bacteria: Prescribing CAYSTON in the absence of known Pa infection in patients with CF is unlikely to provide benefit and increases the risk of development of drug-resistant bacteria.
Adverse Reactions
-
Adverse reactions (>5%) in CAYSTON patients were cough, nasal congestion, wheezing, pharyngolaryngeal pain, pyrexia, chest discomfort, abdominal pain, and vomiting. Adverse reactions reported (<5%) in CAYSTON patients were bronchospasm and rash.
