Questions about taking Oriahnn

Here’s a list of common questions related to taking Oriahnn.

  • What if I miss a dose of Oriahnn? If you miss a dose of Oriahnn, either in the morning or evening, take it as soon as you remember as long as it’s within 4 hours of your scheduled dose. If it’s been longer than 4 hours, skip the missed dose and just take your next scheduled dose. Do not take two doses of Oriahnn to catch up on a missed dose. Doing so can increase your risk for serious side effects.
  • Will I need to use Oriahnn long term? It’s not recommended to take Oriahnn for longer than 24 months. This is because the drug increases the risk of bone loss, which can increase your risk for bone fractures. Talk with your doctor about how long you should take this drug.
  • Can Oriahnn be chewed, crushed, or split? No, you should not crush, split, or chew Oriahnn capsules. It’s not known if this can change how the drug works. If you have trouble swallowing pills, ask your doctor for suggestions. You can also try these tips to help you swallow pills more easily.
  • Should I take Oriahnn with food? Food doesn’t change how Oriahnn works. So, you can take the drug either with or without food.
  • How long does Oriahnn take to work? It may take up to 1 to 2 months for Oriahnn to reduce your symptoms. Ask your doctor what you can anticipate with treatment and when you can expect to have lighter periods.

Overdose

Do not take more Oriahnn than your doctor prescribes. Taking more than this can lead to serious side effects.

Symptoms of overdose

Symptoms caused by an Oriahnn overdose can include:

Call your doctor if you think you’ve taken too much Oriahnn. You can also call 800-222-1222 to reach America’s Poison Centers, or use its online resource. But if you have severe symptoms, immediately call 911 (or your local emergency number) or go to the nearest emergency room.

If you have heavy periods, your doctor may talk with you about Oriahnn.

It’s a prescription drug that’s used to treat heavy menstrual bleeding caused by fibroids in the uterus. (Fibroids are noncancerous growths.) This drug is prescribed for use in adult females* who haven’t yet gone through menopause.

Fibroids can cause you to have heavy bleeding with your periods. It’s not known for sure why this happens.

Oriahnn works to lower certain hormone levels in your body. This way, the lining inside your uterus doesn’t grow as thick as usual. This leads to a lighter flow during your periods.

It’s important to note that it’s not recommended to take Oriahnn for longer than 24 months. This is because the drug may cause bone loss that can’t be reversed. The risk of bone loss with Oriahnn is higher if you take the drug for more than 24 months and if you have other risk factors, such as:

Your doctor will monitor your bone density before you start Oriahnn treatment and during treatment. They may recommend taking vitamin D and calcium supplements while you’re taking Oriahnn.

Ask your doctor for more information about taking Oriahnn for heavy periods caused by fibroids.

Pregnancy and breastfeeding

Oriahnn may cause pregnancy loss if it’s taken during pregnancy. Because of this, the drug is not safe to take while you’re pregnant, especially during the first few months of pregnancy.

Tell your doctor right away if you become pregnant while you’re taking Oriahnn. Keep in mind that Oriahnn can cause irregular or light periods. This can make it tough to tell if you’re pregnant.

Birth control

You’ll need to use a nonhormonal birth control method while you’re taking Oriahnn. And you should keep using birth control for at least 28 days after you stop taking the drug. Condoms and diaphragms are two examples of nonhormonal birth control.

It’s unclear whether it’s safe to use hormonal birth control while taking Oriahnn. Doing so may make Oriahnn less effective. Talk with your doctor about birth control options to help prevent pregnancy while you’re taking this drug.

Boxed warning

Oriahnn has a boxed warning about increasing the risk of blood clots and certain blood vessel problems. A boxed warning is the most serious warning from the Food and Drug Administration (FDA).

Taking hormone therapy that contains estrogen and progestin, such as Oriahnn, may increase the risk of blood clots.

Examples of blood clots that may occur include pulmonary embolism (a blood clot in your lung) and deep vein thrombosis (a blood clot in certain veins in your body). Other blood vessel problems, such as stroke and heart attack, may also occur with Oriahnn.

Certain people may have an increased risk for these side effects. This includes females* older than 35 years of age who smoke. It also includes females with health conditions such as diabetes, high blood pressure that’s not managed, high cholesterol, or obesity. And it includes females who’ve had a blood clot or blood vessel problem in the past, and those who have certain heart valve or heart rhythm conditions (including atrial fibrillation).

Symptoms of a blood clot can vary based on the location of the clot. But they may include:

Be sure to discuss with your doctor your health history and any medical conditions you have. Also, tell your doctor if you smoke or if any family members have had a stroke, heart attack, or other blood vessel problems. The doctor can recommend whether it’s safe for you to take Oriahnn.

Call your doctor right away if you have any symptoms of blood clots while you’re taking Oriahnn. But call 911 or your local emergency number if your symptoms feel life threatening.
