Berotralstat is a prescription medication specifically designed to prevent attacks of hereditary angioedema (HAE) in adults and children 12 years and older. It's a daily oral capsule that works by blocking a protein called plasma kallikrein, which causes the painful swelling episodes that characterize HAE. Think of it as a shield that helps keep your body's swelling response under better control.
What is Berotralstat?
Berotralstat is an oral kallikrein inhibitor that you take once daily to prevent HAE attacks. It belongs to a newer class of medications that target the specific biological pathway responsible for HAE symptoms. Unlike some other HAE treatments that require injections, berotralstat comes as a convenient capsule you can take at home.
This medication represents a significant advancement in HAE management because it offers consistent, daily protection against unpredictable swelling attacks. The drug works by specifically blocking plasma kallikrein, the enzyme that triggers the cascade of events leading to HAE symptoms.
What is Berotralstat Used For?
Berotralstat is used specifically for preventing attacks of hereditary angioedema in people 12 years and older. HAE is a rare genetic condition that causes sudden, severe swelling in various parts of your body, including your face, throat, hands, feet, and abdomen.
The medication is designed for long-term prevention rather than treating acute attacks that are already happening. If you're experiencing an active HAE attack, you'll need different rescue medications. Berotralstat works best when taken consistently every day to maintain steady protection.
Your doctor will typically prescribe berotralstat if you've been having frequent HAE attacks that significantly impact your daily life. It's particularly helpful for people who want to avoid the inconvenience of injectable preventive treatments.
How Does Berotralstat Work?
Berotralstat works by blocking plasma kallikrein, a protein that plays a key role in causing HAE attacks. When this protein becomes overactive in people with HAE, it triggers a chain reaction that leads to increased blood vessel permeability and swelling.
By inhibiting plasma kallikrein, berotralstat essentially interrupts this process before it can cause symptoms. This makes it a moderately strong preventive medication that can significantly reduce both the frequency and severity of HAE attacks when taken consistently.
The medication builds up in your system over time, which is why it's important to take it daily even when you're feeling well. Most people start noticing fewer attacks within the first few weeks of consistent use.

Berotralstat works by preventing the buildup of plasma kallikrein, but it takes time to reach a steady level in your system. Most people notice a gradual reduction in attack frequency rather than an instant halt. It helps your body stabilize over several weeks.
The goal is for you to feel more in control and less worried about unpredictable swelling episodes. While it does not change your personality, the relief from constant vigilance can significantly improve your daily mood. You should feel more like your usual self without the underlying anxiety of an attack.
How Should I Take Berotralstat?
Take berotralstat exactly as prescribed by your doctor, typically one 150mg capsule once daily with food. Taking it with a meal helps your body absorb the medication more effectively and may reduce potential stomach upset.
You can take berotralstat with any regular meal, but try to take it at the same time each day to maintain consistent levels in your bloodstream. Swallow the capsule whole with a full glass of water - don't crush, chew, or open the capsule.
If you have trouble swallowing capsules, talk to your doctor about techniques that might help. The medication needs to be taken as a whole capsule to work properly, so finding a comfortable way to take it is important for your treatment success.

Consistency is the most important factor for keeping the medication levels steady in your blood throughout the day. Picking a time that fits your natural daily routine makes it much easier to remember. Most people find that taking it with a meal helps prevent any minor stomach discomfort.
Many people successfully manage multiple health conditions while taking this medication without any issues. However, some drugs can change how your body processes this treatment or vice versa. Always keep a complete list of your current prescriptions to show your doctor.
How Long Should I Take Berotralstat For?
Berotralstat is typically prescribed as a long-term preventive treatment, meaning you'll likely take it for months or years rather than just a few weeks. Since HAE is a lifelong condition, ongoing prevention is usually necessary to maintain good control of your symptoms.
Your doctor will monitor your response to the medication and may adjust your treatment plan based on how well it's working for you. Some people may need to take it indefinitely, while others might be able to take breaks under close medical supervision.
Never stop taking berotralstat suddenly without talking to your doctor first. Your HAE attacks could return quickly if you discontinue the medication, and your doctor may want to discuss alternative prevention strategies before making any changes.
What Are the Side Effects of Berotralstat?
Like all medications, berotralstat can cause side effects, though not everyone experiences them. The most common side effects are generally mild and tend to improve as your body adjusts to the medication.
Here are the side effects you're most likely to encounter, listed from most common to less frequent:
- Abdominal pain or stomach discomfort
- Diarrhea or loose stools
- Back pain
- Gastroesophageal reflux (heartburn)
- Nausea or mild stomach upset
- Fatigue or feeling more tired than usual
These common side effects usually become less bothersome within the first few weeks of treatment. Taking the medication with food can help reduce stomach-related side effects.
While less common, some people may experience more significant side effects that require medical attention:
- Severe or persistent abdominal pain
- Significant changes in bowel habits
- Unusual fatigue that doesn't improve
- Signs of allergic reaction (rash, itching, difficulty breathing)
Contact your doctor if you experience any side effects that concern you or don't improve over time. Most side effects are manageable, and your healthcare team can help you find ways to minimize discomfort while maintaining effective HAE prevention.

Digestive symptoms like abdominal pain or nausea are among the most frequently reported side effects. These reactions are usually mild and tend to fade as your body gets used to the new routine. Many people find that taking the dose with food helps significantly.
While most side effects are minor, you should always report any symptoms that feel severe or unusual to you. Sudden changes in your health or signs of an allergic reaction require quick professional attention. Trust your instincts if something feels fundamentally wrong.
Who Should Not Take Berotralstat?
Berotralstat isn't suitable for everyone, and there are specific situations where this medication should be avoided or used with extra caution. Your doctor will carefully review your medical history before prescribing it.
You should not take berotralstat if you have a known allergy to the medication or any of its ingredients. Additionally, this medication is not approved for children under 12 years of age, as safety and effectiveness haven't been established in younger patients.
Special caution is needed if you have certain medical conditions that might interact with berotralstat:
- Severe liver disease or significant liver function problems
- Severe kidney disease requiring dialysis
- History of severe gastrointestinal disorders
- Current pregnancy or breastfeeding
Your doctor will also want to know about all other medications you're taking, including over-the-counter drugs and supplements, as some combinations may require dose adjustments or additional monitoring.
Berotralstat Brand Name
Berotralstat is available under the brand name Orladeyo in the United States. This is the only currently available brand formulation of this medication, manufactured by BioCryst Pharmaceuticals.
When you pick up your prescription, you'll see "Orladeyo" on the bottle label along with the generic name berotralstat. Both names refer to the same medication, but insurance coverage and pharmacy availability may vary.
Berotralstat Alternatives
If berotralstat isn't the right fit for you, there are other HAE prevention options available. Your doctor can help you explore alternatives based on your specific needs, lifestyle, and medical history.
Other preventive medications for HAE include injectable options like lanadelumab (Takhzyro) and C1 esterase inhibitor concentrates. These require subcutaneous injections but may be appropriate if you can't tolerate oral medications.
Some people also use older preventive treatments like danazol or tranexamic acid, though these are less commonly prescribed today due to potential side effects. Your doctor will discuss the pros and cons of each option to help you make the best choice for your situation.
Is Berotralstat Better Than Lanadelumab?
Both berotralstat and lanadelumab are effective HAE prevention medications, but they work differently and have distinct advantages. The "better" choice depends on your individual preferences, medical history, and lifestyle factors.
Berotralstat offers the convenience of a daily oral capsule, which many people prefer over injections. It's also newer to the market, so long-term data is still being collected. Lanadelumab, on the other hand, is given as an injection every two weeks and has been available longer with more extensive clinical experience.
In terms of effectiveness, both medications can significantly reduce HAE attack frequency, but individual responses vary. Some people do better on one medication than the other, and your doctor may recommend trying both to see which works best for you.
