Extavia: A Comprehensive Guide to Uses, Dosage, Demographic, Side Effects, Interactions, and Generic Options What is Extavia? Extavia is a medication that contains interferon beta-1b as its active ingredient. It is used to treat relapsing-remitting multiple sclerosis (RRMS), a neurological condition that causes inflammation and damage to the myelin sheath that covers nerve fibers in the brain and spinal cord. RRMS is a chronic and unpredictable disease that affects people of all ages, races, and genders. The exact cause of RRMS is unknown, and there is no cure for the condition. However, medications like Extavia can help manage the symptoms and reduce the frequency and severity of relapses. Uses of Extavia The primary use of Extavia is to treat RRMS. It is indicated for patients who have had at least one relapse in the past year and have lesions on their MRI scans. Extavia works by suppressing the immune system and reducing inflammation in the nervous system. This slows down the progression of the disease and reduces the frequency and severity of relapses. Dosage of Extavia Extavia is administered by injection under the skin (subcutaneously). The dosage and frequency of injections depend on the individual patient's condition and response to treatment. The recommended starting dosage of Extavia is 0.0625 mg (250 mcg) injected subcutaneously every other day. The dosage can be increased to 0.25 mg (1 mL) every other day over time, depending on the patient's response to treatment and tolerance for the medication. It is crucial to follow the healthcare provider's instructions when administering Extavia injection. The drug comes with a patient information leaflet that provides detailed instructions on administration and handling. Demographic for Extavia Extavia is FDA-approved for the treatment of RRMS in adults. It is not recommended for use in children or adolescents under 18 years of age. However, the medication is safe and effective for all adult patients with RRMS, regardless of age, gender, or race. The dosage might vary depending on the patient's response and tolerance. Side Effects of Extavia Like all medications, Extavia can cause side effects. The most common side effects of Extavia are flu-like symptoms such as: - Fatigue - Fever - Headaches - Chills - Muscle aches and pains - Nausea Other side effects may include skin reactions at the injection site, depression, insomnia, and injection site swelling.
