Generic drug: berotralstat
Brand name: Orladeyo
What is Orladeyo (berotralstat), and how does it work?
- Orladeyo (berotralstat) is a prescription medicine used to prevent attacks of Hereditary Angioedema (HAE) in adults and children 12 years of age and older.
- Orladeyo is not used to treat an acute HAE attack.
- Do not take more than one capsule of Orladeyo a day because extra doses can cause heart rhythm problems.
- It is not known if Orladeyo is safe and effective to treat an acute HAE attack.
- It is not known if Orladeyo is safe and effective in children under 12 years of age.
What are the side effects of Orladeyo?
Taking more than one capsule of Orladeyo a day may cause serious side effects, including:
- heart rhythm problems. A heart rhythm problem called QT prolongation can happen in people who take more than one capsule of Orladeyo a day. This condition can cause an abnormal heart beat. Do not take more than one capsule of Orladeyo a day.

These are not all of the possible side effects of Orladeyo. For more information, ask your healthcare provider or pharmacist.
Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What is the dosage for Orladeyo?
- The recommended dosage of Orladeyo is one 150 mg capsule taken orally once daily with food.
Recommended Dosage In Patients With Hepatic Impairment
- No dosage adjustment of Orladeyo is recommended for patients with mild hepatic impairment (Child-Pugh Class A).
- In patients with moderate or severe hepatic impairment (Child-Pugh B or C), the recommended dosage of Orladeyo is one 110 mg capsule taken orally once daily with food.
Recommended Dosage For Concomitant Use With P-Gp Or BCRP Inhibitors
- In patients with chronic administration of P-gp or BCRP inhibitors (e.g., cyclosporine), the recommended dosage of Orladeyo is one 110 mg capsule taken orally once daily with food.
Dosage Adjustment In Patients With Persistent GI Reactions
- Gastrointestinal (GI) reactions may occur in patients receiving Orladeyo. If GI events persist, a reduced dose of 110 mg once daily with food may be considered.
What drugs interact with Orladeyo?
- This section describes clinically relevant drug interactions with Orladeyo. Drug interaction studies are described elsewhere in the labeling.
Potential For Other Drugs To Affect Orladeyo
P-Gp Or BCRP Inhibitors
- Orladeyo is a P-gp and BCRP substrate. A dose of 110 mg Orladeyo is recommended for patients with chronic administration of P-gp or BCRP inhibitors (e.g., cyclosporine).
- Berotralstat is a substrate of P-gp and BCRP. P-gp inducers (e.g., rifampin, St. John's wort) may decrease berotralstat plasma concentration, leading to reduced efficacy of Orladeyo. The use of P-gp inducers is not recommended with Orladeyo.
Potential For Orladeyo To Affect Other Drugs
CYP2D6 And CYP3A4 Substrates
- Orladeyo at a dose of 150 mg is a moderate inhibitor of CYP2D6 and CYP3A4. For concomitant medications with a narrow therapeutic index that are predominantly metabolized by CYP2D6 (e.g., thioridazine, pimozide) or CYP3A4 (e.g., cyclosporine, fentanyl), appropriate monitoring and dose titration is recommended.
- Orladeyo at a dose of 300 mg is a P-gp inhibitor. Appropriate monitoring and dose titration is recommended for P-gp substrates (e.g. digoxin) when co-administering with Orladeyo.
Is Orladeyo safe to use while pregnant or breastfeeding?
- There are insufficient data in pregnant women available to inform drug-related risks with Orladeyo use in pregnancy.
- There are no data on the presence of berotralstat in human milk, its effects on the breastfed infant, or its effects on milk production.
- However, when a drug is present in animal milk, it is likely that the drug will be present in human milk.

Related Disease Conditions
The definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
Pulmonary edema, or fluid in the lungs, can cause symptoms such as shortness of breath. Learn about causes, diagnosis complications, treatment, and prevention.
Edema is swelling caused by fluid accumulation in the tissues of the body and occurs most often in the legs, feet, ankles, or hands. Learn about different types, symptoms, causes, and treatment.
Lymphedema is a condition in which one or more extremities become swollen as the result of an impaired flow of the lymphatic system. There are two types of lymphedema: primary and secondary. Filariasis is the most common cause of lymphedema worldwide. In the U.S., breast cancer surgery is the most common cause. Symptoms include swelling of one or more limbs, cracked and thickening skin, and secondary bacterial or fungal infections of the skin. There is no cure for lymphedema.
Hereditary Angioedema (HAE)
Hereditary angioedema or HAE is a genetic disease that causes swelling of the skin and tissues beneath it. Symptoms of HAE include shortness of breath, mood changes, laryngeal edema (a medical emergency), swelling of the hands and feet, muscle aches, and skin tingling. Treatment of HAE includes medication and avoidance of triggers.
What Causes Angioedema?
What is angioedema? Angioedema is a form of swelling that occurs under the skin. Learn what causes angioedema, its signs and symptoms, how doctors diagnose it, when to see a doctor, and ways to treat this condition.
Your health care provider may refer you to a genetic professional. Universities and medical centers also often have affiliated genetic professionals, or can provide referrals to a genetic professional or genetics clinic. Genetic counseling provides patients and family members the tools to make the right choice in regard to test for a disease or condition.

Genetic Testing: Families With Breast Cancer
Breast cancer can be a killer and the decision to get tested to see if a patient is prone to the disease should be discussed with a doctor -- particularly if the woman has a history of breast cancer in her family. Genetic testing can only tell so much about breast cancer risk, however.
Who Should Get Genetic Counselling?
Genetic counseling is the process that helps you in determining hereditary or genetic (running in your family) problems that might affect you or your family. It is done by a trained professional.
