Pharmacist tips for Orilissa (elagolix)
- Take Orilissa (elagolix) at the same time(s) each day with or without food. Food won't affect how well the medication works.
- Speak to your prescriber about taking a calcium and vitamin D supplement while you're taking Orilissa (elagolix) to keep your bones strong. This medication can raise your risk of bone loss with higher doses and with longer treatment.
- You might notice changes in your menstrual bleeding patterns while you're taking Orilissa (elagolix). Your periods might have less bleeding, be less intense, or be shorter in length. Or, you might not always have a period. This change can make it harder to tell whether you're pregnant if you're sexually active.
- It's important to use non-hormonal birth control, like condoms or Paragard (copper intrauterine device), while you're taking Orilissa (elagolix) and for 28 days after your last dose. Orilissa (elagolix) can raise the risk for pregnancy loss if it's taken in the early stages of pregnancy, and the medication interacts with hormonal birth control. Stop taking Orilissa (elagolix) right away if you become pregnant during treatment.
- Tell your care team if you notice any new or worsening depression, anxiety, or other unusual mood or behavior changes while you're taking Orilissa (elagolix). This medication can cause mood changes.
- If you miss your Orilissa (elagolix) dose, take it as soon as you remember as long as it's within the same day as your missed dose. Don't double up on doses. Skip the missed dose if you remember a day or more later.
- If you have any unused Orilissa (elagolix) left after your treatment ends, get rid of the medication by bringing it to a drug take-back location. You can also throw it away in your household trash after mixing the tablets with coffee grounds or cat litter in a sealed zipper bag. Don't flush unused Orilissa (elagolix) down the toilet.
Common questions about Orilissa (elagolix)
Yes. Orilissa (elagolix) works by blocking GnRH receptors in the brain from releasing hormones like estrogen. Estrogen plays a role in managing endometriosis tissue (tissue normally lining the uterus that's found growing outside the uterus). By blocking estrogen release, Orilissa (elagolix) is thought to prevent the endometriosis tissue from growing. This helps to relieve pain related to endometriosis.
Orilissa (elagolix) is FDA approved for use up to 6 months or 2 years, depending on your other medical conditions. Once you stop taking Orilissa (elagolix), it's possible that your endometriosis symptoms can come back. There's currently not enough information to know how long the effects of the medication will last once you stop taking it. Contact your prescriber if your symptoms return after you stop taking Orilissa (elagolix).
Not everyone who takes Orilissa (elagolix) will experience weight gain, but some people who took the medication reported it as a side effect during clinical studies. Speak to your prescriber if you have concerns about your weight while you're taking Orilissa (elagolix).
It's possible for Orilissa (elagolix) to temporarily stop your period. In clinical studies, up to almost 20% of people who took 150 mg once a day experienced a missed period during the first 6 months of taking the medication. And up to about 50% of people who took 200 mg twice daily reported missing their period within the first 6 months of treatment. Missed periods as a side effect from the medication can make it hard to know whether you're pregnant if you're sexually active. Be sure to take a pregnancy test or tell your prescriber if you miss a period while you're taking Orilissa (elagolix). Most people start having a normal period again within 6 months of stopping the medication.
Although you might not feel symptom relief right away, Orilissa (elagolix) starts to lower hormone levels that play a role in endometriosis within hours after taking your dose. Endometriosis pain relief might not come until a month or later after you start taking the medication. It's important that you continue to take Orilissa (elagolix) as prescribed to try to get the most from treatment. Speak to your prescriber if you have concerns or if you need options for faster pain relief as you wait for Orilissa (elagolix) to work fully.
No, endometriosis medications, like Orilissa (elagolix), don't typically affect or improve fertility. One study found that people who take Orilissa (elagolix) can still ovulate (the release of an egg from the ovary), even though the medication might slightly lower ovulation rates. This means that you can still get pregnant while you're taking Orilissa (elagolix) if you're sexually active. Keep in mind that getting pregnant during treatment is dangerous because the medication can harm your unborn baby. This is why you'll need to use non-hormonal birth control while you're taking Orilissa (elagolix) and for 28 days after your last dose to prevent pregnancy. Speak with your prescriber about family planning.
No, Orilissa (elagolix) isn't birth control. This medication is used to manage pain related to endometriosis, not to prevent pregnancy. It's important that you use a non-hormonal form of birth control to prevent pregnancy while you're taking Orilissa (elagolix) and for 28 days after your last dose if you're sexually active. The reason why is because there's a risk of harm to an unborn baby if it's taken during early pregnancy. And Orilissa (elagolix) can make hormonal birth control work less well. What's more, hormonal birth control can cause Orilissa (elagolix) to not work as well for managing endometriosis symptoms, too.

Risks and warnings for Orilissa (elagolix)
Orilissa (elagolix) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Bone loss
- Risk factors: History of osteoporosis | Taking Orilissa (elagolix) for a long period of time | Taking a higher dose of Orilissa (elagolix)
Orilissa (elagolix) can cause bone loss (a decrease in bone mineral density). It's possible that the bone loss isn't completely reversible after you stop this medication. Your risk is higher if you're taking a higher dose and if you take the medication for a long period of time. You shouldn't take Orilissa (elagolix) if you have a history of osteoporosis
Because of the greater risk for bone loss with longer treatment, your prescriber will limit the amount of time you take Orilissa (elagolix) — either up to 6 months or 2 years, depending on your situation. To help further lower your risk, ask your prescriber about taking calcium and vitamin D supplements during therapy. Your prescriber can also recommend other ways to keep your bones healthy.
Change in menstrual bleeding pattern and effect on recognizing pregnancy
People who take Orilissa (elagolix) might have less bleeding during their monthly menstrual periods. The periods might also be less intense or shorter than usual. These changes can make it harder to tell whether you're pregnant or not. Take a pregnancy test if you think you might be pregnant. And stop taking Orilissa (elagolix) and let your prescriber know if the results of the test say that you're pregnant. This is important because the medication might raise the risk for pregnancy loss if it's taken early in pregnancy.
Suicidal thoughts or behavior or worsened mood problems
- Risk factors: History of depression or suicidal behaviors
Orilissa (elagolix) can raise your risk of depression, mood changes, and suicidal thoughts or behavior. Let your care team know right away if you or your loved ones notice that you have any new or worsening depression, anxiety, or other unusual mood or behavior changes while you're taking Orilissa (elagolix). Your prescriber will discuss with you about whether you should continue taking this medication and whether you should speak with a mental health professional. Call 911 as soon as possible if you have suicidal thoughts or behaviors.
Liver damage
- Risk factors: Liver problems | High dose
In clinical studies, some people who took Orilissa (elagolix) had elevated liver enzyme levels, which can be a sign of liver damage. You're at higher risk if you're taking a higher dose of Orilissa (elagolix).
To be safe, you should take Orilissa (elagolix) at the lowest dose possible to manage your symptoms. Get medical help right away if you have nausea, vomiting, stomach pain, poor appetite, or yellowing of your skin or whites of your eyes. These can be signs of liver damage. Your care team will check your liver health through blood tests to decide whether to continue treatment.
Interactions with hormonal birth control
- Risk factors: Taking Orilissa (elagolix) with birth control containing estrogen or progestin
Orilissa (elagolix) can interact with hormonal birth control. It can make the progestin in combined hormonal birth control work less well, putting you at risk for an accidental pregnancy if you're sexually active. It's not clear what the effects of taking progestin-only birth control (e.g., pills, implants, intrauterine devices) with Orilissa (elagolix) are.
Orilissa (elagolix) can also make the levels of estrogen from hormonal birth control higher in the body and raise the risk for side effects from estrogen. In addition, hormonal birth control might make Orilissa (elagolix) work less well for endometriosis symptoms.
Because of these interactions, it's recommended to use effective non-hormonal birth control methods, like condoms or spermicide. Work with your prescriber to find safe birth control options that best fit your needs while you're taking Orilissa (elagolix).
Risk of harm to unborn baby
Orilissa (elagolix) might raise the risk for pregnancy loss if it's taken early in pregnancy. If you're able to have children, your prescriber might ask you to take a pregnancy test to make sure you're not pregnant before you start taking this medication. Be sure to use effective non-hormonal birth control methods, like condoms, while you're taking Orilissa (elagolix) and for 28 days after your last dose.
Stop taking Orilissa (elagolix) and call your prescriber right away if you become pregnant while you're taking this medication. There's a pregnancy registry that you can enroll in that follows the progress of your health and your baby's health. This helps researchers learn more about the safety of the medication when it's been taken during pregnancy. Enroll in the pregnancy registry by calling 1-833-782-7241 or by visiting their website.
