What Are Warnings and Precautions for Risankizumab?

Contraindications

  • History of serious hypersensitivity reactions to risankizumab or any product excipients

Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Risankizumab?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Risankizumab?”

Cautions

  • Serious hypersensitivity reactions, including anaphylaxis, reported; if a serious hypersensitivity reaction occurs, discontinue risankizumab and initiate appropriate therapy immediately
  • In Phase 3 clinical studies, patients with latent TB were concurrently treated with risankizumab and appropriate TB prophylaxis during the studies, none developed active TB; consider antitubercular therapy before initiating treatment in patients with a history of latent or active TB in whom the course of treatment cannot be confirmed; monitor for signs and symptoms of active TB during and after treatment; do not administer to patients with active TB
  • Before initiating therapy, consider completion of all age-appropriate immunizations according to current immunization guidelines; avoid the use of live vaccines in treated patients; no data available on the response to live or inactive vaccines
  • Administration of vaccines
    • Avoid the use of live vaccines in patients receiving therapy; medications that interact with the immune system may increase the risk of infection following administration of live vaccines
    • Before initiating therapy, complete all age-appropriate vaccinations according to current immunization guidelines; no data are available on the response to live or inactive vaccines
  • Infections
    • In clinical studies, infections occurred more frequently in the risankizumab-treated patients compared with placebo
    • Consider risks and benefits of risankizumab in patients with chronic infection or a history of recurrent infection
    • If an infection develops or is not responding to standard therapy, closely monitor and withhold risankizumab until the infection resolves

Pregnancy and Lactation

  • There is a pregnancy exposure registry that monitors outcomes in women with plaque psoriasis who become pregnant while receiving therapy; patients should be encouraged to enroll by calling 1- 877-302-2161
  • Limited available data with use in pregnant women are insufficient to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcome
  • Human IgG is known to cross the placental barrier; therefore, risankizumab is transmitted from mother to developing fetus
  • Lactation
    • There are no data on the presence of risankizumab-rzaa in human milk, the effects on the breastfed infant, or the effects on milk production
    • Maternal IgG is known to be present in human milk
    • Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or the underlying maternal condition
