Why is this medication prescribed?

Burosumab-twza Injection is prescribed to treat X-linked hypophosphatemia (XLH) in adult and pediatric patients 6 months of age and older. XLH is a rare, inherited disorder characterized by low levels of phosphate in the blood, which can lead to bone abnormalities, such as rickets in children and osteomalacia (softening of the bones) in adults. Burosumab-twza works by blocking the action of a protein that regulates phosphate levels in the body, thereby increasing phosphate levels and improving bone mineralization.

How should this medicine be used?

Burosumab-twza Injection is typically administered subcutaneously (under the skin) by a healthcare professional. Here are the general steps for using Burosumab-twza:

• Preparation: Wash your hands thoroughly with soap and water. Gather all the necessary supplies, including the medication vial, syringe, alcohol swabs, and a sharps disposal container.
• Inspect the medication: Check the expiration date and visually inspect the medication vial for any signs of damage or particles. Do not use the medication if it appears cloudy or contains particles.
• Clean the injection site: Choose an injection site, such as the thigh or abdomen, and clean the skin with an alcohol swab. Allow the skin to dry completely before proceeding.
• Prepare the medication: If the medication needs to be refrigerated, remove it from the refrigerator and let it sit at room temperature for a short period of time as directed by your healthcare provider. Draw up the prescribed dose of Burosumab-twza into the syringe.
• Administer the injection: Pinch a fold of skin at the cleaned injection site. Insert the needle into the skin at a 45 to 90-degree angle, depending on the length of the needle and your healthcare provider’s instructions. Slowly inject the medication, then withdraw the needle and release the skin fold.
• Dispose of used supplies: Safely dispose of the used syringe and needle in a sharps disposal container. Do not recap the needle. Wash your hands again thoroughly after handling the injection supplies.
• Follow-up: Keep track of your injection schedule and attend all follow-up appointments with your healthcare provider. They may adjust your dosage or frequency of injections based on your response to the medication and any changes in your condition.

Always follow the specific instructions provided by your healthcare provider for using Burosumab-twza. If you have any questions or concerns about the administration process, don’t hesitate to ask your healthcare provider or pharmacist for clarification.

Other uses for this medicine

Burosumab-twza Injection is primarily used for the treatment of X-linked hypophosphatemia (XLH), a rare genetic disorder characterized by low levels of phosphate in the blood. While its primary use is for XLH, there may be ongoing research or off-label uses being explored. However, it’s essential to use the medication only as prescribed by your healthcare provider.

What special dietary instructions should I follow?

Burosumab-twza Injection may affect phosphate levels in the body, so it’s essential to maintain a balanced diet. Your healthcare provider may recommend dietary adjustments, including foods rich in phosphate, such as dairy products, meat, fish, nuts, and whole grains. Follow any dietary recommendations provided by your healthcare provider.

What should I do if I forget a dose?
