Short answer: The Norditropin label sets a weekly dose by body weight for children, split into equal doses 6 or 7 days a week: 0.17 to 0.24 mg/kg/week for growth hormone deficiency, up to 0.46 for Noonan syndrome, up to 0.47 for Turner, SGA and idiopathic short stature, and 0.24 for Prader-Willi. Adults inject daily, starting near 0.2 mg/day or at 0.004 mg/kg daily.
This is what the FDA label says. Follow your prescriber. Your prescriber may use a different dose or pace than the label's standard schedule.
What Norditropin is approved for: Norditropin is approved for children with growth failure from growth hormone deficiency, short stature with Noonan syndrome or Turner syndrome, being born small for gestational age without catch-up growth by age 2 to 4, idiopathic short stature (height SDS below -2.25), or growth failure from Prader-Willi syndrome. It is also approved to replace growth hormone in adults with growth hormone deficiency (section 1).

Norditropin is injected under the skin (subcutaneously) in the back of the upper arm, abdomen, buttocks or thigh, rotating sites regularly to avoid fat loss. It is used only if clear and colorless (section 2.1).
Children: the weekly dose is divided into equal doses given 6 or 7 days a week. Adults: the prescribed dose is given daily (sections 2.2 and 2.3).
The label says therapy should be supervised by a physician experienced with these conditions, and an eye (fundoscopic) exam is done before starting and periodically after (section 2.1).
The table below is the label's schedule, from the Dosage and Administration section. Numbers are copied exactly; the section is in brackets.
| Condition | Dose on the label |
|---|---|
| Pediatric GH deficiency | 0.17 mg/kg/week to 0.24 mg/kg/week (0.024 to 0.034 mg/kg/day) |
| Noonan syndrome | Up to 0.46 mg/kg/week (up to 0.066 mg/kg/day) |
| Turner syndrome | Up to 0.47 mg/kg/week (up to 0.067 mg/kg/day) |
| Small for gestational age (SGA) | Up to 0.47 mg/kg/week (up to 0.067 mg/kg/day) |
| Idiopathic short stature | Up to 0.47 mg/kg/week (up to 0.067 mg/kg/day) |
| Prader-Willi syndrome | 0.24 mg/kg/week (0.034 mg/kg/day) |
| Adult GHD, non-weight based | Start approximately 0.2 mg/day (range, 0.15 mg/day to 0.3 mg/day); increase every 1-2 months by approximately 0.1 mg/day to 0.2 mg/day |
| Adult GHD, weight based | Start 0.004 mg/kg daily; increase to a maximum of 0.016 mg/kg daily |
In children, the dose is individualized based on growth response. If growth does not speed up, especially in the first year, the label calls for checking adherence and other causes such as hypothyroidism, undernutrition, advanced bone age or antibodies to growth hormone.
Small for gestational age: a larger starting dose (up to 0.067 mg/kg/day) may be considered in very short (height SDS below -3) or older pubertal children, with a gradual reduction if strong catch-up growth occurs. Children under 4 with height SDS between -2 and -3 may start at 0.033 mg/kg/day.
Norditropin for growth is stopped once the growth plates (epiphyses) have fused.
Adult non-weight-based dosing is adjusted by clinical response and IGF-1 levels, and lowered for side effects or IGF-1 above the age- and gender-specific normal range. Maintenance doses vary a lot between people and between men and women.
The weight-based adult regimen is not recommended for obese patients, who are more likely to have side effects on it.
Older adults may start lower with smaller increases. Estrogen-replete women and people taking oral estrogen may need higher doses. People treated as children whose growth plates have closed are re-evaluated before continuing as adults.
If somatropin-induced intracranial hypertension is diagnosed, Norditropin can be restarted at a lower dose once the signs have resolved.
The Norditropin label gives no missed-dose instruction. Ask your prescriber or pharmacist what to do if a dose is missed.
In Dose Track you set up Norditropin as a protocol with the dose and schedule your prescriber gave you. A protocol can hold dose steps, each with its own dose and length in days or weeks, so a step-up plan like the one on the label can be entered once and the app moves to the next step on its own. Reminders follow the schedule, and every dose is logged with the date and time, so you can see which step you are on and when your last dose was. The app follows what you enter; it does not choose or change a dose.
