- Dosage and Administration
GENOTROPIN was administered as a daily SC injection, and the dose was calculated for each patient every 3 months. In Study 1, the treatment group received GENOTROPIN at a dose of 0.24 mg/kg/week during the entire study. During the second year, the control group received GENOTROPIN at a dose of 0.48 mg/kg/week. In Study 2, the treatment group received GENOTROPIN at a dose of 0.36 mg/kg/week during the entire study. During the second year, the control group received GENOTROPIN at a dose of 0.36 mg/kg/week. Undiagnosed/untreated hypothyroidism may prevent an optimal response to somatropin, in particular, the growth response in children.
DOSAGE FORMS AND STRENGTHS
Mean Cmax levels were 12.4 ng/mL (first injection) and 12.2 ng/mL (second injection), achieved at approximately six hours after dosing. GENOTROPIN 12 mg is designed for use with a reusable device (GENOTROPIN PEN 12) for product reconstitution and drug delivery. After reconstitution, each mL contains 12 mg of somatropin, dibasic sodium phosphate (0.4 mg), glycine (2 mg), mannitol (40 mg), metacresol (3 mg) (as a preservative), monobasic sodium phosphate (0.41 mg) and water for injection. The reconstituted concentration is 12 mg/mL with a deliverable volume of 1 mL. GENOTROPIN 5 mg is designed for use with a reusable device (GENOTROPIN PEN 5) for product reconstitution and drug delivery. After reconstitution, each mL contains 5 mg of somatropin, dibasic sodium phosphate (0.27 mg), glycine (2 mg), mannitol (41 mg), metacresol (3 mg) (as a preservative), monobasic sodium phosphate (0.28 mg) and water for injection.
Important Safety Information & Indications
- Skeletal abnormalities including scoliosis are commonly seen in untreated Turner syndrome patients.
- Elderly patients may be more sensitive to the action of GENOTROPIN, and therefore may be more prone to develop adverse reactions.
- Similar bioavailability has been observed in healthy adult male subjects.
- That is a direct result of shifting hormone levels, plus changes in blood pressure and skin sensitivity; all of which are governed by GH.
- Attach the Needle Guard (Optional)The needle guard is intended to hide the needle before, during and after injection and to reduce needle injury.
- Serious systemic hypersensitivity reactions including anaphylactic reactions and angioedema have been reported with postmarketing use of somatropins.
- As a result, previously undiagnosed impaired glucose tolerance and overt diabetes mellitus may be unmasked during somatropin treatment.
- GENOTROPIN was administered as a daily SC injection at a dose of 0.04 mg/kg/week for the first month of treatment and 0.08 mg/kg/week for subsequent months.
In vitro, preclinical, and clinical tests have demonstrated that GENOTROPIN lyophilized powder is therapeutically equivalent to human growth hormone of pituitary origin and achieves similar pharmacokinetic profiles in normal adults. In patients with GHD or PWS, treatment with GENOTROPIN also normalizes concentrations of IGF-I (Insulin-like Growth Factor-I/Somatomedin C). In adults with GHD, treatment with GENOTROPIN results in reduced fat mass, increased lean body mass, metabolic alterations that include beneficial changes in lipid metabolism, and normalization of IGF-I concentrations. The safety and efficacy of GENOTROPIN in the treatment of pediatric patients born small for gestational age (SGA) were evaluated in 4 randomized, open-label, controlled clinical trials. The safety and efficacy of GENOTROPIN in the treatment of pediatric patients with Prader-Willi syndrome (PWS) were evaluated in two randomized, open-label, controlled clinical trials. Patients received either GENOTROPIN or no treatment for the first year of the studies, while all patients received GENOTROPIN during the second year.

INSTRUCTIONS FOR USEGENOTROPIN 5 (JEEN-o-tro-pin 5)GENOTROPIN PEN 5 is a medical device used to mix and inject doses of reconstituted GENOTROPIN (somatropin) for injection. The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. In GHD patients, administration of somatropin has resulted in lipid mobilization, reduction in body fat stores, and increased plasma fatty acids. Somatropin is a human growth hormone produced by recombinant DNA technology in Escherichia coli. The protein is comprised of 191 amino acid residues and has a molecular weight of 22,124 daltons.
3 Cytochrome P450-Metabolized Drugs
In renal cells, at least a portion of the breakdown products are returned to the systemic circulation. The mean terminal half-life of intravenous GENOTROPIN in normal adults is 0.4 hours, whereas subcutaneously administered GENOTROPIN has a half-life of 3.0 hours in GHD adults. The observed difference is due to slow absorption from the subcutaneous injection site. In healthy adult males, following an SC injection in the thigh of 0.03 mg/kg, the extent of absorption (AUC) of a concentration of 5.3 mg/mL GENOTROPIN was 35% greater than that for 1.3 mg/mL GENOTROPIN.
ADVERSE REACTIONS
Furthermore, overdose with somatropin is likely to cause fluid retention. Preparations of GENOTROPIN contain a small amount of periplasmic Escherichia coli peptides (PECP). Anti-PECP antibodies are found in a small number of patients treated with GENOTROPIN, but these appear to be of no clinical significance. When somatropin is administered subcutaneously at the same site over a long period of time, tissue atrophy may result. This can be avoided by rotating the injection site [see Dosage and Administration (2.3)].
2 Prader-Willi Syndrome in Children
- Serum levels of inorganic phosphorus, alkaline phosphatase, parathyroid hormone (PTH) and IGF-I may increase during somatropin therapy.
- Limited published data indicate that exogenous somatropin does not increase normal breastmilk concentrations of growth hormone.
- Please see accompanying directions for use of the reconstitution and/or delivery device.
- Pancreatitis should be considered in any somatropin–treated patient, especially a child, who develops persistent severe abdominal pain.
- It should be used with caution in nursing mothers because it is not known whether growth hormone is passed into human milk.
- Long hold times are possible on the phone and patients may have to wait to receive a Genotropin pen.
Limited published data indicate that exogenous somatropin does not increase normal breastmilk concentrations of growth hormone. No adverse effects related to somatropin in the breastfeed infant have been reported. Slipped capital femoral epiphyses may occur more frequently in patients with endocrine disorders (including GHD and Turner syndrome) or in patients undergoing rapid growth. Any pediatric patient with the onset of a limp or complaints of hip or knee pain during somatropin therapy should be carefully evaluated. In general, somatropin is contraindicated in the presence of active malignancy. Any preexisting malignancy should be inactive and its treatment complete prior to instituting therapy with somatropin.
Adverse Reactions
Somatropin should be discontinued if there is evidence of recurrent activity. Since growth hormone deficiency may be an early sign of the presence of a pituitary tumor (or, rarely, other brain tumors), the presence of such tumors should be ruled out prior to initiation of treatment. Somatropin should not be used in patients with any evidence of progression or recurrence of an underlying intracranial tumor. Some cases of pancreatitis (inflamed pancreas) have been reported rarely in children and adults receiving growth hormone. There is some evidence that there is a greater risk of this in children than in adults. Literature suggests that girls who have Turner syndrome may have a greater risk of pancreatitis than other children taking growth hormone.
Full Patient Information
- Following a 0.03 mg/kg subcutaneous (SC) injection in the thigh of 1.3 mg/mL GENOTROPIN to adult GHD patients, approximately 80% of the dose was systemically available as compared with that available following intravenous dosing.
- In studies of GENOTROPIN in children with PWS, side effects included fluid retention, aggressiveness, joint and muscle pain, hair loss, headache, and increased pressure in the brain.
- In expanded post-trial extension studies, diabetes mellitus developed in 12 of 3,031 patients (0.4%) during treatment with GENOTROPIN.
- There is no information regarding the presence of somatropin in human milk.
- During the second year, the control group received GENOTROPIN at a dose of 0.36 mg/kg/week.
Growth hormone should not be used in patients with diabetes who have certain types of diabetic retinopathy (eye problems). Throw away the needle and use a new needle with the GENOTROPIN MINIQUICK.See “Disposing of (throwing away) your GENOTROPIN MINIQUICK and needles”. Contact your healthcare provider as soon as possible to get a new Pen.
Drug Interactions
Generally, a dose of 0.16 to 0.24 mg/kg body weight/week is recommended. Other common somatropin-related adverse reactions include injection site reactions/rashes and lipoatrophy (6.1) and headaches (6.2). You are no longer growing, so you no longer need to generate as many new cells on a regular basis. GH directly influences the growth and development of cells, bones, cartilage, muscles, skin, blood vessels, nerves, liver and kidneys.
DOSAGE AND ADMINISTRATION
Patients and caregivers who will administer GENOTROPIN should receive appropriate training and instruction on the proper use of GENOTROPIN from the physician or other suitably qualified health care professional. A puncture-resistant container for the disposal of used syringes and needles should be strongly recommended. Patients and/or parents should be thoroughly instructed in the importance of proper disposal, and cautioned against any reuse of needles and syringes. This information is intended to aid in the safe and effective administration of the medication. The mean clearance of subcutaneously administered GENOTROPIN in 16 GHD adult patients was 0.3 (± 0.11) L/hrs/kg.

- Fluid retention during somatropin replacement therapy in adults may occur.
- In healthy adult males, following an SC injection in the thigh of 0.03 mg/kg, the extent of absorption (AUC) of a concentration of 5.3 mg/mL GENOTROPIN was 35% greater than that for 1.3 mg/mL GENOTROPIN.
- Battery charge is low and will be empty in 1 month.Afterwards the dose can be set and your pen can be used correctly.
Clinical Pharmacology
Scoliosis is also commonly seen in untreated patients with Prader-Willi syndrome. Physicians should be alert to these abnormalities, which may manifest during somatropin therapy. A lower starting dose and smaller dose increments should be considered for older patients, who are more prone to the adverse effects of somatropin than younger individuals. In addition, obese individuals are more likely to manifest adverse effects when treated with a weight-based regimen.
The injection button is rotated too fast or too slow.Point your pen away from your face, press the injection button, press the red release button and continue preparing your dose. The pen has a use period of 2 years starting from the first use by the patient. Your pen should not be used near electrical or electronic equipment, including mobile phones. If your pen has been damaged, it should not be used and should be disposed of as instructed by your healthcare provider. Please see accompanying directions for use of the reconstitution and/or delivery device.
Instructions for Use GENOTROPIN MINIQUICK
Patients with preexisting type 1 or type 2 diabetes mellitus or impaired glucose tolerance should be monitored closely during somatropin therapy. The doses of antihyperglycemic drugs (i.e., insulin or oral/injectable agents) may require adjustment when somatropin therapy is instituted in these patients. Non-weight based — based on published consensus guidelines, a starting dose of approximately 0.2 mg/day (range, 0.15–0.30 mg/day) may be used without genopharm hgh consideration of body weight. The dose should be decreased as necessary on the basis of adverse events and/or serum IGF-I concentrations above the age- and gender-specific normal range. Maintenance dosages vary considerably from person to person, and between male and female patients. Two randomized, open-label, clinical trials were conducted that evaluated the efficacy and safety of GENOTROPIN in Turner syndrome patients with short stature.
The 5 mg and 12 mg presentations of GENOTROPIN lyophilized powder contain m-cresol as a preservative. Systemic hypersensitivity reactions have been reported with postmarketing use of somatropins [see Warnings and Precautions (5.6)]. The GENOTROPIN dosage and administration schedule should be individualized based on the growth response of each patient. As a bodybuilding drug, HGH supplements increase lean body mass, shorten recovery time between workouts, and enhance overall performance with less risk of detection than other performance-enhancing drugs. Genopharm is produced by gene recombination DNA technology (rHGH ) . It contains high purity human growth hormone (HGH) consisting of 191 amino acids.
Dosage and Administration
It should be used with caution in nursing mothers because it is not known whether growth hormone is passed into human milk. Growth hormone should not be used in patients who are critically ill because of surgery, trauma, or respiratory failure. Growth hormone should not be used to increase height in children after the growth plates have closed. The display will continue to show until the battery is completely empty. Your pen can still be used correctly, but the dose size will not be displayed.

- The 5 mg and 12 mg presentations of GENOTROPIN lyophilized powder contain m-cresol as a preservative.
- Linear growth is facilitated in part by increased cellular protein synthesis.
- The mean clearance of subcutaneously administered GENOTROPIN in 16 GHD adult patients was 0.3 (± 0.11) L/hrs/kg.
- Anti-PECP antibodies are found in a small number of patients treated with GENOTROPIN, but these appear to be of no clinical significance.
- Thyroid hormone replacement therapy should be started or adjusted if needed.
- The mean volume of distribution of GENOTROPIN following administration to GHD adults was estimated to be 1.3 (± 0.8) L/kg.
- Patients with Turner syndrome have an inherently increased risk of developing autoimmune thyroid disease and primary hypothyroidism.
The mean (± standard deviation) peak (Cmax) serum levels were 23.0 (± 9.4) ng/mL and 17.4 (± 9.2) ng/mL, respectively. Serum concentrations of inorganic phosphate are increased in patients with GHD after therapy with GENOTROPIN. Linear growth is facilitated in part by increased cellular protein synthesis. Nitrogen retention, as demonstrated by decreased urinary nitrogen excretion and serum urea nitrogen, follows the initiation of therapy with GENOTROPIN. Short-term overdosage could lead initially to hypoglycemia and subsequently to hyperglycemia.
Long-term overdosage could result in signs and symptoms of gigantism and/or acromegaly consistent with the known effects of excess growth hormone [see Dosage and Administration (2)]. Because these adverse events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Serum levels of inorganic phosphorus, alkaline phosphatase, parathyroid hormone (PTH) and IGF-I may increase during somatropin therapy. Monitor all patients with a history of GHD secondary to an intracranial neoplasm routinely while on somatropin therapy for progression or recurrence of the tumor. The GENOTROPIN 5 and 12 mg cartridges are color-coded to help ensure proper use with the GENOTROPIN PEN delivery device. Generally, a dose of up to 0.48 mg/kg body weight/week is recommended.
The linear growth response was greater in Study 055 wherein patients were treated with a larger dose of GENOTROPIN. Adult GHD patients treated with GENOTROPIN at the recommended adult dose [see Dosage and Administration (2)] demonstrate a decrease in fat mass and an increase in lean body mass. When these alterations are coupled with the increase in total body water, the overall effect of GENOTROPIN is to modify body composition, an effect that is maintained with continued treatment.
- Because these adverse events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
- The dose should be decreased as necessary on the basis of adverse events and/or serum IGF-I concentrations above the age- and gender-specific normal range.
- When somatropin is administered subcutaneously at the same site over a long period of time, tissue atrophy may result.
- Growth hormone should not be used in children with Prader-Willi syndrome who are very overweight or have severe breathing problems.
- Table 1 displays the adverse events reported by 5% or more of adult GHD patients in clinical trials after various durations of treatment with GENOTROPIN.
- Serum concentrations of inorganic phosphate are increased in patients with GHD after therapy with GENOTROPIN.
- Throwing away (disposing of) used needles, cartridges and your GENOTROPIN PEN 12Put the used needles and cartridges in a FDA-cleared sharps disposal container right away after use.
In childhood cancer survivors, treatment with growth hormone may increase the risk of a new tumor, particularly certain benign brain tumors. This risk may be higher in patients who were treated with cranial radiation. Also, patients and their doctors should check regularly for skin changes. As seen in Table 6, height velocity SDS and height SDS values were smaller at baseline and after treatment with GENOTROPIN when the normative standards were utilized as opposed to the Turner syndrome standard. Patients who received GENOTROPIN showed significant increases in linear growth during the first year of study, compared with patients who received no treatment (see Table 3). Linear growth continued to increase in the second year, when both groups received treatment with GENOTROPIN.
Safety and effectiveness of GENOTROPIN have been established in pediatric patients with ISS based on data from one randomized, open-label, clinical trial with GENOTROPIN in 102 pediatric patients [see Clinical Studies (14.5)]. Fluid retention during somatropin replacement therapy in adults may occur. Clinical manifestations of fluid retention (e.g., edema, arthralgia, myalgia, nerve compression syndromes including carpal tunnel syndrome/paresthesia) are usually transient and dose dependent. Because children with certain rare genetic causes of short stature have an increased risk of developing malignancies, practitioners should thoroughly consider the risks and benefits of starting somatropin in these patients.
Similar bioavailability has been observed in healthy adult male subjects. Pediatric patients with hypopituitarism sometimes experience fasting hypoglycemia that is improved by treatment with GENOTROPIN. Somatropin is contraindicated in patients with Prader-Willi syndrome who are severely obese, have a history of upper airway obstruction or sleep apnea, or have severe respiratory impairment. There have been reports of sudden death when somatropin was used in such patients [see Warnings and Precautions (5.2)]. Thyroid function should be checked regularly during growth hormone therapy. Thyroid hormone replacement therapy should be started or adjusted if needed.
All of the bodily functions governed by GH are the areas that begin to suffer as you age. As GH levels drop, your skin tone deadens, wrinkles appear, and skin slackens. That is a direct result of shifting hormone levels, plus changes in blood pressure and skin sensitivity; all of which are governed by GH. This is due to decreased cell production and a reduced metabolic rate. This is due to the slower rejuvenation of cells, this time in your brain. Put the used GENOTROPIN MINIQUICK and needles in a FDA-cleared sharps disposal container right away after use.
Limited published data indicate that somatropin treatment increases cytochrome P450 (CYP450)-mediated antipyrine clearance in man. These data suggest that somatropin administration may alter the clearance of compounds known to be metabolized by CYP450 liver enzymes (e.g., corticosteroids, sex steroids, anticonvulsants, cyclosporine). Careful monitoring is advisable when somatropin is administered in combination with other drugs known to be metabolized by CYP450 liver enzymes.
