Administration Instructions INCRELEX is administered by subcutaneous injection only. Do not administer intravenously. INCRELEX injection sites should be rotated to a different site (upper arm, thigh, buttock or abdomen) with each injection to help prevent lipohypertrophy. INCRELEX should be administered using sterile disposable syringes and needles.
The syringes should be of small enough volume so that the prescribed dose can be withdrawn from the vial with accuracy. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if the solution is cloudy or contains particulate matter.
If using syringes that measure dose in units, doses in mg/kg must be converted to units using the following formula: Weight (kg) × Dose (mg/kg) × 1 mL/10 mg × 100 units/1 mL = units/injection.
Contraindications
Known Hypersensitivity to mecasermin ( 4 ) Closed Epiphyses ( 4 ) Malignant Neoplasia ( 4 ) Known Hypersensitivity INCRELEX should not be used by patients who are allergic to mecasermin (rhIGF-1) or any of the inactive ingredients in INCRELEX, or who have experienced a severe hypersensitivity to INCRELEX [see Warnings and Precautions (5.2) and Adverse Reactions (6) ]. Closed Epiphyses INCRELEX should not be used for growth promotion in patients with closed epiphyses. Malignant Neoplasia INCRELEX is contraindicated in pediatric patients with malignant neoplasia or a history of malignancy [see Warnings and Precautions (5.7) and Adverse Reactions (6) ].
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary There are no available data on INCRELEX use in pregnant women. Exposure to INCRELEX during pregnancy is unlikely because the drug is not indicated for use after epiphyseal closure. In animal reproduction studies, there were no observed embryo-fetal development abnormalities with intravenous administration of INCRELEX to pregnant rats and rabbits during fetal organogenesis given at exposures up to 11 and 3 times the maximum recommended human dose (MRHD) of 0.24 mg/kg/day based on body surface area (BSA), respectively (see Data ) . The estimated background risk of birth defects and miscarriage for the indicated population is unknown. In the U.S.
general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data Studies to assess embryo-fetal toxicity evaluated the effects of INCRELEX during organogenesis in Sprague Dawley rats given 1, 4, and 16 mg/kg/day and in New Zealand White rabbits given 0.125, 0.5, and 2 mg/kg/day, administered intravenously. There were no observed embryo-fetal developmental abnormalities in rats given up to 16 mg/kg/day (11 times the MRHD based on BSA comparison).
In the rabbit study, the NOAEL for fetal toxicity was 0.5 mg/kg/day (approximately equivalent to the MRHD based on BSA) due to an increase in fetal death at 2 mg/kg. INCRELEX displayed no teratogenicity or maternal toxicity in rabbits given up to 2 mg/kg (3 times the MRHD based on BSA).

Not the price at the counterThese are not what a patient pays at the pharmacy counter. They are what pharmacies, health plans, and government buyers pay, before manufacturer rebates. A patient's cost depends on their insurance (copay, coinsurance, or deductible) or the pharmacy's cash price.
