"April 24, 2014 -- As many as 4 in 10 Americans have sneezing, runny nose, and watery eyes due to allergies. If you're one of them, allergy shots can help ease your reaction to the plants, insects, or animals that trigger your symptoms. But they r"...
Activities Requiring Mental Alertness
In clinical trials, the occurrence of somnolence has been reported in some patients taking ASTEPRO [see ADVERSE REACTIONS]. Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness and motor coordination such as operating machinery or driving a motor vehicle after administration of ASTEPRO. Concurrent use of ASTEPRO with alcohol or other central nervous system depressants should be avoided because additional reductions in alertness and additional impairment of central nervous system performance may occur [see DRUG INTERACTIONS].
Patient Counseling Information
See FDA-approved patient labeling (PATIENT INFORMATION and Instructions for Use).
Activities Requiring Mental Alertness
Somnolence has been reported in some patients taking ASTEPRO. Caution patients against engaging in hazardous occupations requiring complete mental alertness and motor coordination such as driving or operating machinery after administration of ASTEPRO [see WARNINGS AND PRECAUTIONS].
Concurrent Use of Alcohol and other Central Nervous System Depressants
Avoid concurrent use of ASTEPRO with alcohol or other central nervous system depressants because additional reductions in alertness and additional impairment of central nervous system performance may occur [see WARNINGS AND PRECAUTIONS].
Common Adverse Reactions
Inform patients that the treatment with ASTEPRO may lead to adverse reactions, most common of which include pyrexia, dysgeusia, nasal discomfort, epistaxis, headache, sneezing, fatigue, somnolence, upper respiratory infection, cough, rhinalgia, vomiting, otitis media, contact dermatitis, and oropharyngeal pain. [see ADVERSE REACTIONS].
Instruct patients to prime the pump before initial use and when ASTEPRO has not been used for 3 or more days [see DOSAGE AND ADMINISTRATION].
Keep Spray Out of Eyes
Instruct patients to avoid spraying ASTEPRO into their eyes.
Keep Out of Children’s Reach
Instruct patients to keep ASTEPRO out of the reach of children. If a child accidentally ingests ASTEPRO, seek medical help or call a poison control center immediately.
Carcinogenesis, Mutagenesis, Impairment Of Fertility
In 2-year carcinogenicity studies in rats and mice, azelastine hydrochloride did not show evidence of carcinogenicity at oral doses up to 30 mg/kg and 25 mg/kg, respectively. These doses were approximately 150 and 60 times the maximum recommended human daily intranasal dose [MRHDID] on a mg/m² basis.
Azelastine hydrochloride showed no genotoxic effects in the Ames test, DNA repair test, mouse lymphoma forward mutation assay, mouse micronucleus test, or chromosomal aberration test in rat bone marrow.
Reproduction and fertility studies in rats showed no effects on male or female fertility at oral doses up to 30 mg/kg (approximately 150 times the MRHDID in adults on a mg/m² basis). At 68.6 mg/kg (approximately 340 times the MRHDID on a mg/m² basis), the duration of estrous cycles was prolonged and copulatory activity and the number of pregnancies were decreased. The numbers of corpora lutea and implantations were decreased; however, pre-implantation loss was not increased.
Use In Specific Populations
Pregnancy Category C
There are no adequate and well-controlled clinical trials in pregnant women. Azelastine hydrochloride has been shown to cause developmental toxicity in mice, rats, and rabbits. ASTEPRO Nasal Spray should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
In mice, azelastine hydrochloride caused embryo-fetal death, malformations (cleft palate; short or absent tail; fused, absent or branched ribs), delayed ossification, and decreased fetal weight at approximately 170 times the maximum recommended human daily intranasal dose (MRHDID) in adults (on a mg/m² basis at a maternal oral dose of 68.6 mg/kg/day which also caused maternal toxicity as evidenced by decreased body weight). Neither fetal nor maternal effects occurred in mice at approximately 7 times the MRHDID in adults (on a mg/m² basis at a maternal oral dose of 3 mg/kg/day).
In rats, azelastine hydrochloride caused malformations (oligo-and brachydactylia), delayed ossification and skeletal variations, in the absence of maternal toxicity, at approximately 150 times the MRHDID in adults (on a mg/m² basis at a maternal oral dose of 30 mg/kg/day). Azelastine hydrochloride caused embryo-fetal death and decreased fetal weight and severe maternal toxicity at approximately 340 times the MRHDID (on a mg/m² basis at a maternal oral dose of 68.6 mg/kg/day). Neither fetal nor maternal effects occurred at approximately 15 times the MRHDID (on a mg/m² basis at a maternal oral dose of 2 mg/kg/day).
In rabbits, azelastine hydrochloride caused abortion, delayed ossification and decreased fetal weight and severe maternal toxicity at approximately 300 times the MRHDID in adults (on a mg/m² basis at a maternal oral dose of 30 mg/kg/day). Neither fetal nor maternal effects occurred at approximately 3 times the MRHDID (on a mg/m² basis at a maternal oral dose of 0.3 mg/kg/day).
It is not known whether azelastine hydrochloride is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when ASTEPRO is administered to a nursing woman.
The safety and effectiveness of ASTEPRO have been established for seasonal allergic rhinitis in pediatric patients 2 to 17 years of age and perennial allergic rhinitis in pediatric patients 6 months of age to 17 years of age [see Clinical Studies]. The safety and effectiveness of ASTEPRO in pediatric patients below 6 months of age have not been established.
Clinical trials of ASTEPRO did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.This monograph has been modified to include the generic and brand name in many instances.
