Considering reproduction: Asenapine may affect both males' and females' chances of having children. It causes a condition known as hyperprolactinemia, in which the body makes too much of a hormone called prolactin.

Prolactin is responsible for functions like sperm production and menstrual regulation. If you plan to have children, your healthcare professional may prescribe other drugs.

Pregnancy: The safety data of this medicine in pregnancy is limited and, therefore, its routine use during pregnancy is not recommended. Use of this medicine while pregnant, especially during the third trimester, may increase the risk of extrapyramidal symptoms (abnormal muscle movements) in newborns after delivery.

In infants, symptoms may include:

  • Drowsiness
  • Feeding disorder
  • Tremors
  • Breathing issues
  • Muscle tone issues 

These symptoms may lead to the hospitalization of your newborn.

If you were assigned female at birth, are 18 to 45 years old, or were exposed to asenapine while pregnant, enroll in the Atypical Antipsychotics Pregnancy Registry by calling 866-961-2388 or going online to the pregnancy registry.

Nursing: In animal studies, Saphris was present in breast milk. However, there are no studies conducted on people who are breastfeeding. Talk to your medical provider if you plan to breastfeed.

Children: The use of this drug in children under age 10 has not been evaluated.

Older Adults: It may take longer for Saphris to clear out of the system of people over age 65 with psychosis than in younger adults. Taking antipsychotics, like Saphris, in this population is not advised due to the risk of adverse effects, including stroke and death in people with dementia.
