- None

- See “What Are Side Effects Associated with Using Tezepelumab?”
Long-Term Effects
- See “What Are Side Effects Associated with Using Tezepelumab?”
Cautions
- Hypersensitivity reactions
- Hypersensitivity reactions (e.g., rash, and allergic conjunctivitis) can occur after administration; typically occur within hours of administration, but in some instances have a delayed onset (e, days)
- In the event of a hypersensitivity reaction, consider the benefits and risks to determine whether to continue or discontinue treatment
- Acute asthma symptoms or deteriorating disease
- Do not use it to treat acute asthma symptoms, acute exacerbations, acute bronchospasm, or status asthmaticus
- Instruct patients to seek medical attention if asthma remains uncontrolled or worsens after treatment initiation
- Abrupt reduction of corticosteroid dosage
- Do not discontinue systemic or inhaled corticosteroids abruptly upon initiating therapy
- Reduce corticosteroid dose gradually, if appropriate, under the direct supervision of a physician
- Parasitic (helminth) infection
- Treat pre-existing helminth infection before initiating
- If patients become infected while taking tezepelumab and do not respond to antihelminth treatment, discontinue until the infection resolves
- Live attenuated vaccine
- Concomitant use with live, attenuated vaccines has not been evaluated
- Avoid administering live vaccines while taking tezepelumab
Pregnancy and Lactation
- Data are not available regarding use in pregnant females to evaluate for any drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes.
- Placental transfer of monoclonal antibodies is greater during the third trimester; therefore, potential effects on the fetus are likely to be greater during that time.
- Clinical considerations
- Females with poorly or moderately controlled asthma have an increased risk of preeclampsia in the mother and prematurity, low birth weight, and small for gestational age, in the neonate
- Closely monitor asthma control in pregnant females and adjust treatment to maintain optimal control
- Lactation
- Data are not available regarding the presence of tezepelumab in human milk, its effects on breastfed infants, or its effects on milk production.
- IgG is present in human milk in small amounts; tezepelumab was present in the milk of cynomolgus monkeys postpartum following dosing during pregnancy.
- Consider the developmental and health benefits of breastfeeding along with the mother's clinical need for tezepelumab and any potential adverse effects on the breastfed infant or from the underlying maternal condition.
