At Kratz Allergy & Asthma, we use Fasenra to treat severe eosinophilic asthma. Fasenra is a highly effective medication that has been approved by the FDA for the treatment of severe eosinophilic asthma in patients aged 12 years and older. In clinical trials, Fasenra has been shown to significantly reduce asthma exacerbations and improve lung function in patients with high levels of eosinophils in their blood.
Studies have also shown that Fasenra can help reduce the need for oral corticosteroids, which can have serious side effects when used long-term. Fasenra has also been well-tolerated in clinical trials, with few serious side effects reported. The FDA approval of Fasenra is based on extensive clinical data and represents an important step forward in the treatment of severe eosinophilic asthma.
Fasenra is generally considered safe and effective, but as with all medications, there are potential side effects to be aware of. It is important for patients to be informed about these side effects so that they can make informed decisions about their treatment and know what to expect.
*Please Note: These are only potential side effects and you may not experience any side effects at all after receiving Fasenra.
Potential Side-Effects Of Fasenra And How To Manage Them
I. Injection Site Reactions
Injection site reactions are common and typically involve slight pain, swelling, or redness at the site where the injection was administered. While these reactions are usually mild and resolve on their own within a few days, the pain can last in some cases. However, it is easily manageable. Just apply a cold compress to the injection site for 15 mins two to three times a day. It will reduce the swelling and pain. Over-the-counter pain relievers, such as acetaminophen or ibuprofen, may also be helpful.
II. Headache
Headache is a common side effect of Fasenra. It usually occurs within a few hours of receiving the injection and is generally mild and short-lived. You do not have to worry about it. The cause of these headaches is not fully understood, but it is thought to be related to the immune response triggered by the medication.
To manage a headache after Fasenra, over-the-counter pain relievers can be used. Resting in a quiet, dark room may also help to alleviate the symptoms. However, patients can experience more severe headaches in very rare cases that persist for several days. In such cases, you must consult your doctor.
III. Sore Throat
If you experience a sore throat after receiving Fasenra, it can make swallowing or talking difficult. You can try drinking warm liquids like tea or soup, or even just warm water with honey and lemon to manage this side effect. Also, you can use throat lozenges or sprays to soothe the throat. Gargling with warm salt water can soothe the pain as well. Also, avoid consuming spicy food or cold food as long as the sore throat persists.
IV. Back Pain
Some patients have complained about back pain after receiving Fasenra. The pain is not severe but it can cause discomfort and prevent you from carrying out your daily activities. In most cases, it does not require much attention. Maintaining good posture and doing gentle stretching exercises for a few days after the injection can help to relieve pain.
Also, using a supportive pillow or cushion while sitting can help. You can consider applying a hot or cold compress to the affected area as well. Over-the-counter pain relievers can also be used for reducing pain.
V. Flu-like Symptoms
Flu-like symptoms such as fever, chills, and muscle aches can occur after receiving a Fasenra injection. This happens because Fasenra works by targeting specific cells in the immune system, which can lead to an immune response similar to the flu.
These symptoms do not last more than a few days. They are usually mild and self-limited, and go away on their own. Just take rest and drink plenty of fluids during those days. It is also recommended to avoid contact with individuals who are sick to prevent the spread of infection.
VI. Nausea
Nausea is a side effect of Fasenra. It is important to note that while nausea is a potential side effect of Fasenra, not everyone who receives the medication will experience this symptom. Just like the other symptoms, you may experience nausea at any time from a few hours to a few days after receiving a Fasenra injection.
Nausea happens because Fasenra stimulates the immune system to attack certain cells that can trigger an inflammatory response. This immune response can cause the release of chemicals that lead to nausea. As long as you keep your body hydrated, you should not experience a lot of discomfort. Also, eat small and frequent meals instead of large meals. Ginger tea or ginger candies can also be beneficial in alleviating nausea symptoms. Avoiding spicy, greasy, or high-fat foods can also help reduce nausea.
VII. Dizziness
Some patients experience a sensation of lightheadedness or a spinning feeling after receiving Fasenra. Dizziness can be a concern if it affects balance or coordination. It occurs because the drug targets certain immune cells in the body. This causes a temporary decrease in blood pressure. Additionally, Fasenra can cause dehydration. Dehydration can contribute to feelings of lightheadedness. It is essential to stay hydrated by drinking plenty of fluids. Also, always lie down or sit down if you feel dizzy. This will ensure that you do not fall down and injure yourself. Avoiding sudden movements can also help. Maintaining a healthy diet is also recommended.
