Cosentyx Pre-Filled Syringe

Cosentyx is classified as a human interleukin-IL-17A antagonist. This FDA-approved prefilled syringe is used to treat moderate to severe plaque psoriasis. Suitable for adult patients, the medication provides relief to people requiring systemic therapy or phototherapy. While the recommended dosage of Cosentyx prefilled syringe is 300 mg subcutaneous injection at weeks 0, 1, 2, 3, and 4 every four weeks, 150 mg of these injections are also acceptable in some patients. However, even the best medications have their side effects. Patients using these prefilled syringes are prone to developing various infections. Therefore, it is essential to use this medication under the guidance of a medical professional. 

Product Overview

Cosentyx is an immunosuppressant injection that helps the body reduce the effects of chemical substances causing inflammation. The injection contains the active ingredient secukinumab, a monoclonal antibody indicated for treating moderate to severe plaque psoriasis, including raised, silvery flaking of the skin in patients over 6 years old. The medication is also approved by the FDA for ankylosing spondylitis, psoriatic arthritis, active non-radiographic axial spondyloarthritis in adults, and active enthesitis-related arthritis in children aged 4 years or above.

Cosentyx is a prefilled injection available in various strengths, including 150 mg and 300 mg. The drug is injected under the skin of the abdomen, thigh, or upper arm and is suitable for adults or children suffering from psoriasis. The drug reduces the immune system’s inflammatory response by targeting and neutralizing interleukin-17A, a protein involved in inflammatory processes. As a result, it offers relief from the painful symptoms of autoimmune diseases. 

While the medication provides various benefits to patients, it can have common side effects that include upper respiratory infections, headache, and injection site reactions. Therefore, it is important to inform your healthcare provider if you have any medical conditions or ongoing medications to avoid drug reactions. In case you have mistakenly missed your dose, take it as soon as possible unless it is close to the time for the next dose. Always follow the guidance of your healthcare provider regarding the use and storage of Cosentyx and promptly report any adverse effects or concerns for appropriate management.

How Does Cosentyx Pre-Filled Syringe Work?

Cosentyx is approved to treat plaque psoriasis in adults and children. These conditions can affect any part of your body but commonly occur in the areas near the knees, elbows, and scalp. It has been observed that psoriasis and psoriatic arthritis are caused due to an overactive immune system. This, in turn, causes inflammation in the body and leads to various side effects like redness, fever, and white patches in the mouth. These conditions arise due to a protein in your body named IL-17A, which is responsible for the overactive immune system. To avoid such situations, Cosentyx is used as it restricts or blocks this protein in the body. As a result, the patient is provided with reduced inflammation and symptoms associated with it.
