Repatha Evolocumab
MedicationIntroduction
Repatha is the brand name for evolocumab. It is a prescription medicine that lowers LDL cholesterol1,3. LDL means low-density lipoprotein.
Repatha may also lower the risk of certain heart and blood vessel events in eligible adults1,3. These events include heart attack and stroke3,5.
This guide reviews Repatha evolocumab uses side effects and safety information. It explains how the medicine works and why a clinician may prescribe it. It also covers common side effects and serious allergy risks.
Repatha is not right for everyone. A clinician should weigh its likely benefits against its risks before prescribing it3.
Exact approval details may change. Check the latest FDA label for approved groups and age limits1,2. Also check it for outcomes, doses, storage rules, missed doses, and device steps1,2.
Overview: What Repatha Is and How It Works
Repatha and the PCSK9 inhibitor drug class
Repatha contains evolocumab. It belongs to a group of medicines called PCSK9 inhibitors3. PCSK9 is short for proprotein convertase subtilisin kexin type 9.
PCSK9 plays a role in the way the body handles LDL cholesterol. Evolocumab blocks PCSK9 and helps the liver clear more LDL from the blood3.
A clinician must decide whether Repatha fits a person’s care plan. That choice should weigh the likely benefits and risks3.
Repatha forms one part of a wider cholesterol plan. It is used with a proper diet and exercise3. It does not replace healthy habits or other care prescribed by a clinician.
How evolocumab lowers LDL cholesterol
The liver helps clear LDL from the blood. Blocking PCSK9 increases the liver’s ability to remove LDL cholesterol3.
This action can lead to a large drop in LDL cholesterol3. Lowering LDL is a key evolocumab use for eligible patients1,3.
A lower LDL result does not mean other care should stop. Patients should keep following their diet and exercise plans3. They should also keep using other prescribed treatment unless their clinician changes it.
Do not change another cholesterol medicine on your own. Ask the prescribing clinician before making any change.
How Repatha is given
Repatha is given by a subcutaneous injection. This means it is injected under the skin3,4. A patient or caregiver may use the prescribed injection device.
Product instructions can vary by device. The correct steps depend on the current directions supplied with that device.
Use only the prescribed device and dosing plan. Do not copy another person’s injection schedule.
Check the latest FDA label for exact doses and schedules1,2. It also contains current storage, preparation, age, and device directions1,2.
Ask a pharmacist, nurse, or prescriber to explain the device. Ask for more help if an injection step is unclear.
Causes of High LDL and Why Treatment May Be Needed
Some people who receive evolocumab have primary hyperlipidemia1,3. This term means that a person has high levels of blood fats, such as cholesterol.
Other patients have an inherited form of high cholesterol3. These conditions include heterozygous familial hypercholesterolemia and homozygous familial hypercholesterolemia3.
Heterozygous familial hypercholesterolemia is also called HeFH. Homozygous familial hypercholesterolemia is also called HoFH.
The risk of a major heart or blood vessel event may also guide treatment. Current labeling includes risk reduction for eligible adults with increased cardiovascular risk1,5. Cardiovascular means related to the heart and blood vessels.
Repatha does not remove the need for diet and exercise. It supports those steps and other treatment recommended by a clinician3.
Treatment: Approved Uses and Potential Benefits
Use for high LDL cholesterol
Current FDA labeling includes Repatha for eligible patients with primary hyperlipidemia1,2. This use includes patients who need treatment for high LDL cholesterol1,3.
FDA approval does not mean Repatha suits everyone with high LDL. A clinician must review the diagnosis and current treatment.
The clinician should also compare the likely benefits with the possible risks3. Individual treatment needs can differ.
Some patients may already use other methods to manage cholesterol. Repatha becomes one part of the care plan. It does not replace a proper diet and exercise3.
Approved uses may change over time. Check the latest FDA label for exact age rules and approved groups1,2.
Use for inherited cholesterol disorders
Current FDA labeling includes evolocumab for eligible patients with HeFH and HoFH1,3. Both are inherited forms of high cholesterol3.
In HeFH, a person has one affected copy of a related gene. In HoFH, a person has two affected copies. These terms help clinicians describe the type of inherited disorder.
Repatha can lower LDL cholesterol in eligible patients with HeFH or HoFH3. A clinician must decide whether it fits the patient’s needs.
The prescribed schedule may vary by approved use. Patients should follow their own prescription. They should not use another patient’s schedule.
Use the latest FDA label to confirm age limits and approved groups1,2. Check it for the exact dosing rules as well1,2.
A caregiver may need to give the injections. The caregiver should learn how to use the prescribed device.
Use for cardiovascular risk reduction
Current FDA labeling indicates Repatha for certain adults at increased cardiovascular risk1,5. It may reduce specified major heart and blood vessel events in eligible adults1,5.
These events include cardiovascular death, heart attack, and stroke3,5. They also include unstable angina that needs hospital care3,5. Coronary revascularization is another listed event3,5.
Unstable angina is a type of chest pain. Coronary revascularization is a procedure used to restore blood flow to the heart.
Eligibility depends on a person’s health and the current FDA label. Repatha is not suitable for every adult with possible heart risk.
Repatha is not emergency treatment for a heart attack or stroke. If signs of a heart attack or stroke occur, seek emergency care now or call emergency services.
Treatment does not replace diet, exercise, or other prescribed medicines3. Keep following the care plan unless the treating clinician changes it.
Symptoms and Common Repatha Side Effects
Cold, flu, and respiratory symptoms
Repatha side effects can vary by the condition being treated1,2. The adverse events listed in studies also reflect comparisons with placebo groups.
A placebo is an inactive treatment used for comparison in a study. A reported event does not prove that Repatha caused every case.
Several reactions occurred more often with Repatha than with placebo in adults with primary hyperlipidemia1,2. These included the following effects:
Nasopharyngitis, which is inflammation involving the nose and throat1,2.
Upper respiratory tract infection1,2.
Influenza, which is commonly called the flu1,2.
Injection-site reactions1,2.
Nasopharyngitis may be described as a cold-like illness. Upper respiratory infections affect parts of the breathing system above the lungs.
The label shows a different common reaction pattern for adults with established cardiovascular disease. It lists diabetes, nasopharyngitis, and upper respiratory infection in this group1,2.
Clinical trial patterns may differ between patient groups1,2. They do not show that each event was caused by Repatha.
Contact the prescribing clinician if cold-like or flu-like effects persist. Also call if they worsen or become hard to manage.
If breathing trouble occurs, seek emergency care now or call emergency services. It may be a sign of a serious allergy4.
Back pain and other reported effects
Back pain occurred more often than placebo in adults treated for primary hyperlipidemia1,2. It does not affect every person who uses Repatha.
Other reported effects may differ between studies and patient groups1,2. The treated condition can affect the pattern shown in the label1,2.
Do not assume that every new symptom comes from the medicine. A clinician can review when the symptom began and consider other causes.
Contact a clinician if back pain lasts or gets worse. Also call if it limits daily tasks or becomes hard to manage.
Do not stop a prescribed medicine without asking about the next step. A suspected serious allergic reaction is an exception. It requires action under emergency or clinician guidance1,2.
Injection-site reactions and home care
An injection-site reaction occurs where the needle enters the skin. Pain or irritation can occur at the injection site4.
The FDA label lists injection-site reactions among common Repatha side effects1,2. This pattern applies to adults treated for primary hyperlipidemia1,2.
An injection-site reaction does not happen after every dose. The type and strength of a reaction can vary.
Follow the instructions supplied with the prescribed device. Use the method shown by a trained health professional.
Check current FDA information for preparation and injection-site directions1,2. Also review the device-specific instructions before giving a dose1,2.
Contact the prescriber if a reaction is severe or does not improve. Also call if it spreads, worsens, or becomes hard to manage.
If a site reaction occurs with breathing trouble, seek emergency care now or call emergency services4. If the face, lips, tongue, or throat swell, seek emergency care now or call emergency services4.
Serious Warnings and Safety Information
Serious allergic reactions and angioedema
Serious hypersensitivity reactions have occurred with evolocumab1,2. Hypersensitivity means an allergic reaction to a medicine or one of its ingredients.
Angioedema has also occurred in people using Repatha1,2. Angioedema is swelling in the deeper layers under the skin.
This swelling may affect the face, lips, tongue, or throat4. It can be dangerous when it affects breathing.
FDA Repatha safety warnings say to stop treatment after signs of a serious allergic reaction1,2. The reaction needs standard care and monitoring until it goes away1,2.
Follow emergency or clinician guidance after a suspected serious allergy. Do not inject another dose until a qualified clinician reviews what happened.
Who should not use Repatha
Repatha has a contraindication. This means the medicine must not be used when a certain risk is present.
People with a past serious allergic reaction to evolocumab must not use Repatha1,2. This also applies after a serious reaction to any Repatha excipient1,2.
An excipient is an inactive product ingredient. Review known medicine and product allergies with the prescriber before treatment.
Tell the clinician about any past unusual reaction to evolocumab3. Also discuss allergic reactions to other medicines3.
A clinician can check the product ingredients and current Repatha safety warnings. This review helps show whether the medicine is suitable.
Symptoms that require urgent medical care
Serious allergic reactions are less common than routine Repatha side effects4. However, they can be dangerous4.
Learn the warning signs before giving the first injection.
If trouble breathing occurs after an injection, seek emergency care now or call emergency services4.
If the face, lips, tongue, or throat swell, seek emergency care now or call emergency services4.
If a rash occurs with breathing trouble, seek emergency care now or call emergency services4.
If raised skin bumps occur with throat swelling, seek emergency care now or call emergency services4.
If signs of a serious allergy occur, stop Repatha and get care under emergency guidance1,2.
Do not wait for a routine office reply when emergency signs appear. Do not give another dose until a clinician reviews the reaction.
Using Repatha Safely
Information to share before treatment
Tell the prescriber about past reactions to evolocumab or other medicines1,3. Also report known allergies to product ingredients.
Bring an updated list of medicines and health products to the appointment. This helps the clinician review the current care plan.
Ask how Repatha fits with diet and exercise. Evolocumab is used along with a proper diet and exercise3.
The decision to use evolocumab should balance benefits and risks3. Ask which treatment goals the clinician plans to track.
Current FDA information should confirm the exact approved group and age limits1,2. Never copy another patient’s treatment plan.
Safe storage and injection technique
Use only the Repatha device prescribed for you. Repatha is injected under the skin3,4.
Read the current instructions that come with the product. Storage, preparation, and injection steps may differ by device.
Check the latest FDA label for storage and preparation directions1,2. Also check it for approved injection areas and device steps1,2.
Ask a pharmacist what to do after a storage mistake. Do not guess how to use a damaged or unfamiliar device.
Follow current product instructions when choosing injection sites. If a dose seems incomplete, ask a pharmacist or prescriber before trying again.
Monitoring, missed doses, and side-effect reporting
Attend the follow-up visits recommended by the treating clinician. Ask how the clinician will judge whether treatment is helping.
Do not double the next injection after a missed dose. Follow the product instructions or ask a pharmacist or prescriber.
Missed-dose steps depend on the prescribed schedule. Check current FDA information for the exact directions1,2.
Do not change the dose or the time between doses on your own. Follow the treatment plan written for you.
Report severe, lasting, or worsening side effects to the prescriber. Also report effects that disrupt daily life or are hard to manage.
Suspected side effects may be reported to Amgen Medical Information. Its listed telephone number is 1-800-772-64362. Reports may also be sent through the FDA MedWatch program2.
When to See a Doctor
Contact the prescribing clinician if a side effect lasts or gets worse. Examples include back pain, cold-like symptoms, or injection-site irritation.
Ask for medical advice before changing the dose or schedule. Also ask before switching the injection device.
Contact a pharmacist or prescriber if the full dose may not have entered the skin. Do not repeat the dose without guidance.
Emergency allergy signs require immediate action.
If trouble breathing develops, seek emergency care now or call emergency services4.
If the face, lips, tongue, or throat swell, seek emergency care now or call emergency services4.
If breathing trouble occurs with a suspected allergy, stop treatment and seek emergency care now1,2,4.
If throat swelling occurs after a dose, call emergency services now and do not take another dose1,2,4.
After emergency care, tell the prescriber what happened. Do not use Repatha again until a clinician reviews the reaction.
A history of serious allergy to evolocumab is a contraindication1,2. A serious allergy to a Repatha ingredient is also a contraindication1,2.
Conclusion
Repatha can greatly lower LDL cholesterol in eligible patients3. It blocks PCSK9 and helps the liver remove more LDL from the blood3.
The medicine may also reduce listed heart and blood vessel events in eligible adults1,5. These possible benefits do not make Repatha right for every patient.
Common Repatha side effects include cold-like illness and upper respiratory infection1,2. Influenza, back pain, and injection-site reactions are also common in adults with primary hyperlipidemia1,2.
Serious allergic reactions have occurred with Repatha1,2. These reactions include angioedema1,2. A past serious allergy to evolocumab or a Repatha ingredient is a contraindication1,2.
Review Repatha evolocumab uses side effects and safety information with a qualified clinician. Follow current directions for doses, storage, injections, and missed doses1,2.
Check the latest FDA prescribing information before treatment. It gives exact approved groups, age limits, outcomes, and dosing schedules1,2. It also provides current storage rules, missed-dose steps, and device directions1,2.
If breathing trouble occurs, seek emergency care now or call emergency services4. If the face, lips, tongue, or throat swell, seek emergency care now or call emergency services4.
