About Skytrofa
What is this medication?
Skytrofa is a prescription medicine used to treat growth failure in children one year of age and older who weigh at least 11.5 kilograms and do not produce enough growth hormone. This condition is medically known as growth hormone deficiency. The active ingredient in this medication is lonapegsomatropin-tcgd, which acts as a long-acting prodrug of somatropin to help stimulate physical growth and bone development.
This medication is specifically designed to be administered as a subcutaneous injection once per week, offering a less frequent alternative to traditional daily growth hormone injections. It works by slowly releasing human growth hormone into the bloodstream over the course of seven days. This sustained release helps pediatric patients maintain more consistent hormone levels to support their growth goals throughout the week.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
