Why is this medication prescribed?

Mecasermin injection is a medication prescribed for the treatment of a rare genetic disorder called “insulin-like growth factor-1 (IGF-1) deficiency” or “primary IGF-1 deficiency.” This condition is characterized by an inadequate production of IGF-1, which is a hormone that plays a crucial role in promoting growth and development, especially during childhood and adolescence. Mecasermin is a synthetic form of IGF-1, and it is used to replace or supplement the naturally occurring IGF-1 in individuals who have a deficiency.

How should this medicine be used?

Here’s how Mecasermin injection is typically used:

• Administration: Mecasermin is administered as a subcutaneous (under the skin) injection. The injection is usually given by a healthcare provider, but in some cases, patients or their caregivers may be trained to administer it at home.
• Dosage: The dosage of Mecasermin is individualized and based on factors such as age, weight, and the severity of the IGF-1 deficiency. Your healthcare provider will determine the appropriate dose for you or your child.
• Injection Sites: The injection is typically given in the fatty tissue just beneath the skin. Common injection sites include the upper arms, thighs, or abdomen. It’s essential to rotate injection sites to prevent skin irritation or lumps at the injection site.
• Frequency: Mecasermin is usually administered once daily. The specific timing and frequency will be determined by your healthcare provider.
• Monitoring: While on Mecasermin therapy, your healthcare provider will monitor your progress closely. They may perform regular blood tests to assess IGF-1 levels and adjust the dosage as needed.
• Compliance: It’s crucial to follow your healthcare provider’s instructions carefully and not miss any doses of Mecasermin. Consistency in treatment is essential to achieve the desired results.
• Adverse Effects: Like all medications, Mecasermin can have potential side effects. These can include local reactions at the injection site, headaches, joint pain, and muscle pain. More severe side effects are rare but can occur. It’s important to report any unusual symptoms or side effects to your healthcare provider promptly.
• Growth Assessment: In pediatric patients, regular monitoring of growth parameters (height and weight) is essential to evaluate the effectiveness of Mecasermin therapy.

It’s essential to work closely with your healthcare provider to ensure that Mecasermin is administered correctly and to address any questions or concerns you may have about the medication. This medication is typically reserved for individuals with a confirmed diagnosis of primary IGF-1 deficiency, and its use should be under the supervision of a knowledgeable healthcare team.

Other uses for this medicine

Mecasermin injection is primarily used for the treatment of primary insulin-like growth factor-1 (IGF-1) deficiency, as previously mentioned. It is a specific medication designed to address this rare genetic disorder. However, there are no other widely recognized or approved uses for Mecasermin. It is not a medication for general growth enhancement or for treating other conditions.

What special precautions should I follow?

Special Precautions for Mecasermin Injection:
