Orilissa Overview

Reviewed: July 25, 2018
Updated: 

Orilissa is a prescription medication used to treat moderate to severe pain caused by endometriosis. Endometriosis is a painful disorder in which tissue similar to that which forms the lining of your uterus grows outside of your uterine cavity. These growths are sometimes called lesions.

During your menstrual cycle, when estrogen levels rise, these lesions can grow. And later, during your period, the lesions can break down and shed. This can cause pain throughout the month. 

Orilissa belongs to a group of drugs called gonadotropin releasing hormone (GnRH) receptor antagonists. By blocking GnRH receptors, Orilissa decreases signals to your ovaries to produce estrogen. This leads to reduced estrogen levels.

This medication comes in tablet form and is usually taken once or twice a day, with or without food.

Common side effects of Orilissa include hot flashes, night sweats, and nausea.

Orilissa Precautions

Serious side effects have been reported with Orilissa including the following:

  • Bone Loss (decreased Bone Mineral Density [BMD]). While you are taking Orilissa, your estrogen levels will be low. This can lead to BMD loss. Your BMD may improve after stopping Orilissa, but may not recover completely. It is unknown if these bone changes could increase your risk for broken bones as you age. Your healthcare provider (HCP) may order a DXA scan to check your BMD.
  • Effects on Pregnancy. Do not take Orilissa if you are trying to become or are pregnant, as your risk for early pregnancy loss may increase. If you think you are pregnant, stop taking Orilissa right away and call your HCP. 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 hormone-free birth control (such as condoms or spermicide) while taking Orilissa and for one week after stopping Orilissa. Birth control pills that contain estrogen may make Orilissa less effective. It is unknown how well Orilissa works while on progestin-only birth control.
  • Suicidal thoughts, actions, or behavior, and worsening of mood. Call your HCP right away, or call 911 if an emergency, if you have any of these symptoms, especially if they are new, worse, or bother you: thoughts about suicide or dying, try to commit suicide, new or worse depression or anxiety, or other unusual changes in behavior or mood. You or your caregiver should pay attention to any changes, especially sudden changes in your mood, behaviors, thoughts, or feelings.
  • Abnormal liver tests. Call your HCP right away if you have any of these signs and symptoms of liver problems: yellowing of the skin or the whites of the eyes (jaundice), dark amber-colored urine, feeling tired, nausea and vomiting, generalized swelling, right upper stomach area pain, or bruising easily.

Do not take Orilissa if you:

  • are allergic to Orilissa or to any of its ingredients
  • are or may be pregnant
  • have osteoporosis
  • have severe liver disease
  • are taking medicines known as strong OATP1B1 inhibitors such as cyclosporine or gemfibrozil. Ask your healthcare provider if you are not sure if you are taking one of these medicines.

Orilissa Food Interactions

Orilissa and Lactation
