What is the most important information I should know about OPSYNVI?

  • Serious birth defects.
OPSYNVI can cause serious birth defects if taken during pregnancy.
  • Females must not be pregnant when they start taking OPSYNVI or become pregnant during treatment with OPSYNVI or for 1 month after stopping treatment with OPSYNVI.
  • Females who are able to get pregnant must have a negative pregnancy test before beginning treatment with OPSYNVI, each month during treatment with OPSYNVI and 1 month after stopping OPSYNVI.
    Talk to your healthcare provider about your menstrual cycle. Your healthcare provider will decide when to do the pregnancy test and will order a pregnancy test for you depending on your menstrual cycle.
    • Females who are able to get pregnant are females who:
      • have entered puberty, even if they have not started their menstrual period, and
      • have a uterus, and
      • have not gone through menopause. Menopause means that you have not had a menstrual period for at least 12 months for natural reasons, or that you have had your ovaries removed.
    • Females who are not able to get pregnant are females who:
      • have not yet entered puberty, or
      • do not have a uterus, or
      • have gone through menopause. Menopause means that you have not had a menstrual period for at least 12 months for natural reasons, or that you have had your ovaries removed, or
      • are infertile for other medical reasons and this infertility is permanent and cannot be reversed.
Females who are able to get pregnant must use 2 acceptable forms of birth control during treatment with OPSYNVI, and for 1 month after stopping OPSYNVI because the medicine may still be in the body.
  • If you have had a tubal sterilization, have a progesterone implant, or have an IUD (intrauterine device), these methods can be used without another form of birth control.
  • Talk with your healthcare provider or gynecologist (a doctor who specializes in female reproduction) to find out about options for acceptable birth control that you may use to prevent pregnancy during treatment with OPSYNVI.
  • If you decide that you want to change the form of birth control that you use, talk with your healthcare provider or gynecologist to be sure that you choose another acceptable form of birth control.
See the chart below for Acceptable Birth Control Options during treatment with OPSYNVI. Chart
  • Do not have unprotected sex. Talk to your healthcare provider or pharmacist right away if you have unprotected sex or if you think your birth control has failed. Your healthcare provider may talk with you about using emergency birth control.
  • Tell your healthcare provider right away if you miss a menstrual period or think you may be pregnant.
Females can only receive OPSYNVI through a restricted program called the Macitentan-Containing Products Risk Evaluation and Mitigation Strategy (REMS). If you are a female who can get pregnant, you must talk to your healthcare provider, understand the benefits and risks of OPSYNVI, and agree to all of the instructions in the Macitentan-Containing Products REMS.
Males can receive OPSYNVI without taking part in the Macitentan-Containing Products REMS.
