Benralizumab 

Fasenra

Fasenra (benralizumab) is a biologic medication approved by the FDA for treating severe eosinophilic asthma in adults and children aged 12 and older. It is administered as a subcutaneous injection, either by a healthcare professional using a prefilled syringe or by the patient using a prefilled autoinjector pen after proper training. Fasenra targets and eliminates eosinophils, reducing inflammation in the airways and decreasing asthma flare-ups. While there are no known long-term side effects, it is essential to discuss your health history and any medications you take with your doctor before starting Fasenra. It is not a rescue inhaler & should not be used for sudden asthma attacks. If you plan to buy Fasenra online, ensure to talk to your doctor. They will guide you on the associated benefits and risks of the medication and help you prevent the risk of developing adverse side effects.

Product Overview

Fasenra (benralizumab) is a biologic medication designed to treat severe eosinophilic asthma in adults & children (12 years or older). As a monoclonal antibody, Fasenra targets eosinophils, white blood cells that contribute to airway inflammation and asthma flare-ups. By attaching to the interleukin-5 receptor on eosinophils, Fasenra signals the immune system to eliminate these cells, thereby reducing inflammation and the risk of asthma attacks.

Fasenra is administered as a subcutaneous injection. It comes in two forms: a prefilled syringe, administered by a healthcare professional and a prefilled autoinjector pen, which patients can use after receiving training from a healthcare provider. The recommended dosage is one injection every four weeks for the first three months, followed by one injection every eight weeks. There are no known long-term side effects of Fasenra, but it is crucial to discuss your health history & any current medications with your doctor before starting treatment. Fasenra is not intended for use during sudden asthma attacks and should not replace a rescue inhaler.

Important safety information includes avoiding known allergens, using a peak flow meter daily, and considering an annual flu shot to prevent exacerbations. While there are no known interactions with other drugs, herbs, or supplements, always inform your healthcare provider of all medications you are taking. Fasenra must be stored in a refrigerator but can be kept at room temperature for up to 14 days if needed. Proper disposal of unused medication and used auto injector pens is essential to prevent accidental use and environmental harm. Always follow your doctor’s guidance on using and storing Fasenra.

How Do You Take Fasenra?

When considering treatment with Fasenra, you must know how to administer the medication properly. Below are some of these steps:

• Fasenra is administered as a subcutaneous injection and is available in two forms: a prefilled syringe & a prefilled autoinjector pen.
  • Prefilled Syringe:
    • Administration: A healthcare professional will administer Fasenra using the prefilled syringe. You will need to visit a doctor’s office or clinic for this.
    • Injection Sites: The injection may be given in various parts of your body, such as the upper arms, thighs, or abdomen.
    • Scheduling: Before you leave the office or clinic, ensure you have scheduled your next appointment for a Fasenra injection.

[Note: Your doctor will decide the right amount for you based on your condition, following guidelines and studies on the drug. They’ll adjust it as needed over time.]

What Is the Mechanism of Action of Fasenra?

Fasenra targets a specific type of white blood cell known as eosinophils, which play a role in the inflammation associated with asthma. Eosinophils have a protein on their surface called the interleukin-5 receptor. Fasenra works by attaching to this receptor on the eosinophils, signaling the immune system to eliminate them. By reducing the number of eosinophils, the medication decreases inflammation in the airways, which lowers the risk of asthma flare-ups.

Within just 24 hours of administration, Fasenra can remove nearly all eosinophils from the bloodstream. However, treating severe eosinophilic asthma effectively usually takes more time, and improvements in the condition are gradual. It is important to continue taking Fasenra to maintain control over asthma and reduce the likelihood of flare-ups. 

Important Safety Information for Using Fasenra

What Are the Side Effects of Fasenra?

Common Side Effects of Fasenra: Before you use Fasenra for eosinophilic asthma, you must know that the medication can cause several side effects. These reactions are generally common and do not require immediate medical attention, as they subside within a few days or weeks. However, if they persist for more than the mentioned period or worsen, contact your medical professional. Some of these common side effects may include:

• Sore Throat: This side effect is among the most common reactions experienced by many patients, especially after receiving the injection. This happens as the medication can cause mild irritation to the throat, leading to inflammation. It could also be a result of a mild immune response triggered by the medication. The sore throat is generally temporary and may lessen once your body adjusts to the effects of the medication. To manage this side effect, drink warm liquids, use throat lozenges & gargle with salt water; doing so will soothe the irritation. 
• Headache: Headaches can happen due to the body’s immune response to the drug or changes in blood pressure levels. It is very common to happen at the initial stage of the treatment and will gradually subside within a few days or weeks. The pain may range from mild to moderate and can be easily managed by staying hydrated and using over-the-counter pain relievers. However, if the pain stays or worsens, you should consult a medical professional.
• Injection Site Reaction: Fasenra can cause reactions at the injection site, especially at the start of the treatment. This happens due to the body’s localized immune response to the drug, which is a natural process. If you experience reactions like redness, swelling, pain, or irritation at the injection, do not panic, as it subside once the body adjusts to the drug. To reduce this risk, try to change the injection site each time and apply a cool compress or take over-the-counter pain relievers.  
• Fever: Many patients may experience fever at the beginning of their treatment due to the body’s immune response to the medication. This can be an indication of your immune system’s reaction to the injection. The fever usually lasts for a short duration and wears off with time. If you are using Fasenra for severe asthma management, try to stay hydrated and use over-the-counter medications, if needed, to prevent the risk of this side effect. 

Serious Side Effects of Fasenra: Benralizumab, one of the active ingredients of Fasenr, can cause adverse reactions. If these side effects are left overlooked, they result in life-threatening situations. So, when considering treatment with Fasenra, be mindful of any unusual symptoms. Some of these side effects may include:

• Severe Allergic Reaction: Fasenra can cause severe allergic reactions in certain patients, especially those with extreme sensitivity. This reaction happens when your immune system mistakenly identifies the drug as a threat. If you notice any unusual signs after taking the medication, consult your doctor right away. Some of its symptoms may include:
  • Itchiness
  • Skin rash
  • Flushing (temporary deepening of skin color, redness, or warmth)
  • Difficulty breathing
  • Swelling on the lips, eyelids, feet, hands, mouth, tongue, or throat
  • Hives

[Note: Remember, this list may not cover all possible side effects. Always consult with your healthcare giver for medical advice about side effects.]

Are There Any Warnings for Fasenra?

Before you plan to buy Fasenra online, discuss your health history with your doctor, as this medication may not be suitable for you if you have certain medical conditions or other health factors. These warnings are as follows:

• Parasitic Infections: Fasenra may decline the ability of your body to fight off parasitic infections. If you have a helminth infection which is caused by a worm parasite, inform your doctor before starting Fasenra. They will treat your infection before you begin using Fasenra.
• Allergic Reaction: If you have ever noticed or experienced a mild or severe allergic reaction to this medication or any of its ingredients, you should not take Fasenra. Ask your doctor for alternative medication options.
• Alcohol: There are no known interactions between Fasenra and alcohol. However, alcohol can be risky for people with asthma. Studies from sources like the National Readmissions Database and the National Emergency Department Sample show that drinking alcohol might cause asthma attacks. If you drink alcohol, it’s important to discuss with your doctor how much is safe for you to consume while you are being treated with Fasenra.
• Birth Control: The safety of taking Fasenra during pregnancy is not known. If you or your sexual partner may become pregnant, it is important to discuss your birth control needs with your doctor while using Fasenra. This will help in making sure that you can avoid an unplanned pregnancy while taking the medication.
• Pregnancy: The safety of taking Fasenra during pregnancy is not fully known. There haven’t been clinical trials in humans to determine the effects of the drug during pregnancy. However, studies of similar medications suggest that if Fasenra is used during the third trimester (week 28 through birth), it may pass to the developing fetus. In animal studies, Fasenra did not harm the offspring of animals given the drug. However, animal studies do not always predict what may occur in humans. If you are pregnant or planning to become pregnant, discuss it with your doctor before taking Fasenra. They can advise you on the safety of using Fasenra during pregnancy and recommend other treatment options if necessary.
• Breastfeeding: The safety of using Fasenra while breastfeeding is not fully known. Clinical trials of similar medications indicate that Fasenra may pass into breast milk. However, it is unclear if the drug would have any effect on a breastfed child. If you are breastfeeding or planning to breastfeed, discuss with your doctor before taking Fasenra. They can help you understand the benefits and potential risks of breastfeeding while on this medication. Your doctor can also suggest the safest ways to feed your child.

What Are the Fasenra Precautions?

When considering treatment with Fasenra for eosinophilic asthma, you must be aware of the below precautions, as following these preventive measures can reduce the risk of potential side effects:

• If you are allergic to benralizumab, Fasenra, or any ingredients present in the medication, inform your medical provider beforehand. The product may contain certain components that can cause severe allergic reactions.
• Before considering treatment with this medication, tell your healthcare provider about your complete medical history. Doing so will prevent the risk of developing severe side effects.

• Avoid things that can worsen breathing issues, like dust, smoke, pet fur, pollen, and mold.
• Don’t give your medicine to anyone else.
• Since the flu can make your breathing problems worse, check with your primary caregiver or pharmacist to see if you should get a flu vaccine every year.

Frequently Asked Questions

Can I use Fasenra to treat asthma attacks?

No, Fasenra should not be used to treat sudden asthma symptoms, also known as asthma attacks or flare-ups. Fasenra is designed for the long-term management of asthma, working to prevent asthma flare-ups from occurring by modifying the underlying disease process in your body. It does not relieve symptoms once an asthma attack has started.

If you experience an asthma attack, Fasenra will not be effective in managing those immediate symptoms. Instead, you will likely need to use a rescue inhaler or other emergency treatments as prescribed by your doctor. Be sure to consult with your doctor about the most effective ways to manage and prevent asthma attacks.

Is Fasenra a biologic?

Yes, Fasenra is classified as a biologic drug. Unlike traditional drugs that are synthesized from chemicals, biologics are derived from living cells. Specifically, Fasenra is a type of biologic known as a monoclonal antibody. These antibodies are specially designed to target specific proteins within the immune system—the body’s defense against infection. Fasenra works by attaching to these proteins and blocking their actions, which are responsible for triggering the symptoms of asthma. This targeted approach helps to control and reduce asthma symptoms effectively.

Is Fasenra a steroid?

No, Fasenra is not a steroid. It is classified as a biologic, a type of medication derived from living cells, distinct from steroids, which are usually synthesized from chemicals. Both Fasenra and steroids are used to manage asthma, but they function differently within the body.

Fasenra specifically targets and removes eosinophils, a type of white blood cell present in the airways, which contribute to inflammation and the triggering of asthma flare-ups. In contrast, steroids work by broadly reducing inflammation and decreasing mucus production in the airways, improving breathing. Steroids are often used daily for long-term asthma management or intermittently during acute asthma flare-ups. On the other hand, Fasenra is not taken daily and is not suitable for treating sudden asthma symptoms. If you have any questions about how Fasenra or steroids work for asthma, it’s best to consult your primary caregiver or pharmacist for more detailed information.

Are there long-term side effects of Fasenra?

No, Fasenra is not known to cause long-term side effects. Clinical trials have shown that people who took the medicine for up to 48 weeks didn’t experience any long-term side effects. Additionally, no long-term side effects have been reported since Fasenra became available. However, if you experience a side effect that persists, it is important to talk with your doctor. They may help identify the cause of your symptoms and suggest ways to manage them.

Is weight gain a side effect of Fasenra?

No, weight gain is not a common side effect of Fasenra. However, certain people have reported weight gain anecdotally, while others have reported weight loss. If you are concerned about your weight changes during your treatment with Fasenra, consult your doctor.
