Pregnancy & Lactation
Pregnancy
Not absorbed systemically following intranasal administration and maternal use is not expected to result in fetal exposure to the drug
Clinical considerations
- Pregnant women infected with seasonal influenza are at increased risk of severe illness associated with influenza infection compared with nonpregnant women
- Pregnant women with influenza may be at increased risk for adverse pregnancy outcomes, including preterm labor and delivery
Lactation
Not absorbed systemically by the mother following intranasal administration and breastfeeding is not expected to result in exposure of the breastfed child
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Vaccine; vaccines convey active immunity via stimulation of production of endogenously produced antibodies
Pharmacokinetics
Onset: Three weeks after vaccination
Duration: 6 months or more
Distribution: Nasal cavity, stomach, brain, and lungs
Administration
Intranasal Administration
Administer at beginning of influenza season
Each sprayer contains a single dose (0.2 mL); administer one-half of the contents of the single-dose intranasal sprayer into each nostril
With the patient in upright position, place tip of syringe applicator just inside the nostril and depress plunger as rapidly as possible
Children aged 2 years through 8 years
- If child requires 2 doses, administer at least 4 weeks apart (see number of doses)
Number of doses
- 2 doses administered a minimum of 4 weeks apart are required during child’s first season of vaccination for optimal protection
- Children who have previously received ≥2 total doses of trivalent or quadrivalent influenza vaccine at least 4 weeks apart, require only 1 dose for the current flu season
- The 2 doses of influenza vaccine do not have to have been administered in the same season or consecutive seasons
- From ACIP recommendations: MMWR 2018 Aug 24 / 67(3);1-20
