Medication Guide

Read this Medication Guide before you start treatment and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or treatment.

Important information

Orilissa may cause serious side effects, including:

  • bone loss (decreased bone mineral density).
    • While you are taking Orilissa, your estrogen levels will be low. Low estrogen levels can lead to bone mineral density loss.
    • Your bone density may improve after you stop taking Orilissa but complete recovery may not occur. It is unknown if these bone changes could increase your risk for broken bones as you age.
    • Your healthcare provider may advise you to take vitamin D and calcium supplements as part of a healthy lifestyle that promotes bone health.
    • If you have conditions or take other medicines that can cause bone loss, or if you have broken a bone with minimal or no injury, your healthcare provider may order an X-ray test called a DXA scan to check your bone mineral density.
  • effects on pregnancy
    • Do not take Orilissa if you are trying to become or are pregnant. It may increase the risk of early pregnancy loss.
    • If you think you are pregnant, stop taking Orilissa right away and call your healthcare provider.
    • Orilissa may change your menstrual periods (irregular bleeding or spotting, a decrease in menstrual bleeding, or no bleeding at all), making it hard to know if you are pregnant. Watch for other signs of pregnancy such as breast tenderness, weight gain and nausea.
    • Orilissa does not prevent pregnancy. You will need to use effective methods of birth control that do not contain hormones such as condoms or spermicide while taking Orilissa and for one week after you stop taking Orilissa. Birth control pills that contain estrogen may make Orilissa less effective. It is not known how well Orilissa will work while you are taking progestin-only birth control such as injections or implants.
    • Talk to your healthcare provider about which birth control to use during treatment. Your healthcare provider may change the birth control you were on before you start treatment.
