Important Safety Information for Humogen
What is the most important information I should know about
• Do not take Humogen if you are having serious complications
after having open heart surgery, abdominal surgery, or serious
injuries involving many body systems, or are having
life-threatening breathing problems. Deaths have been reported
in such cases.
• Do not use Humogen in children with Prader-Willi syndrome who
are severely obese or have a history of blocked upper airways or
other severe breathing problems, or sleep apnea. Deaths have
been reported in such cases. Humogen is not approved for the
treatment of patients with Prader-Willi syndrome.
• Do not use Humogen if you have active cancer. Growth hormone
deficiency can be an early sign of some tumors in the brain or
pituitary gland. The presence of these types of tumors should be
ruled out by your doctor before you start Humogen.
• Serious allergic reactions have been reported with Humogen.
Humogen is contraindicated if you know you have allergies to
growth hormone or any of its ingredients. Tell your doctor if
you have an allergic reaction. Do not mix Humogen with the
supplied diluent if you are allergic to metacresol or glycerin.
• Your doctor should check your blood sugar regularly while you
are taking Humogen, especially if you have diabetes,
pre-diabetes, or risk factors for diabetes. New cases of type 2
diabetes have been reported in patients taking Humogen.
• Tell your doctor if you have any visual changes accompanied by
headache, nausea, and/or vomiting while taking Humogen. This may
be a sign of increased pressure in the brain.
• Adults may retain water during Humogen treatment. This may be
brief and may increase with higher doses of Humogen.
• If you have hypoadrenalism and are on glucocorticoid
replacement therapy, your doctor may increase your dosage when
you initiate growth hormone treatment.
• Your doctor should test your thyroid function periodically
during Humogen therapy. Thyroid hormone treatment may need to be
started or adjusted.
• Fracture in the ball of the hip joint can occur in children
who have endocrine problems and in children who have rapid
growth. Any child taking Humogen who develops a limp or
complains of hip or knee pain should be seen by a doctor to
check for this.
• Progression of curvature of the spine (scoliosis) can occur in
children who have rapid growth. Humogen has not been shown to
increase the occurrence of this condition. If the child has
scoliosis, the doctor should carefully monitor the progression
of the scoliosis during Humogen treatment.
• Cases of pancreatitis (inflammation of the pancreas) have been
reported rarely in children and adults receiving growth hormone.
Consult a doctor if you develop abdominal pain while taking
• You should rotate your injection sites to avoid breakdown of
skin and fat. Seek prompt medical attention for any allergic
reaction you experience to the injection of Humogen.
Who should not take Humogen?
Humogen should not be used by:
• People with serious complications after having open heart
surgery, abdominal surgery, serious injuries involving many body
systems, or with life-threatening breathing problems
• Children with Prader-Willi syndrome who are severely obese or
have a history of severe breathing problems
• People with active cancer
• People who have had an allergic reaction to growth hormone
• People with diabetic disease of the retina (the lining in the
back of the eyeball)
• Children who have closed growth plates in their bones

When this medication is given to
newborns, mix with sterile water for injection that does not
contain a preservative. A preservative (benzyl alcohol) which may
be found in the liquid used to mix this product can infrequently
cause serious problems (sometimes death), if given by injection to
an infant during the first months of life. The risk is greater
with lower birth weight infants and is greater with increased
amounts of benzyl alcohol. Symptoms include sudden gasping, low
blood pressure, or a very slow heartbeat. Report these symptoms to
the doctor immediately should they occur. Caution is advised when
using in the elderly because elderly patients may be more
sensitive to its effects.
Humogen® [somatropin (rDNA origin) for injection] is injected

Pull back on the syringe plunger
until it reaches the 1cc/1ml point on the syringe barrel, or the
volume indicated by your healthcare provider.
While holding the syringe in one
hand, pull the needle cap straight off with the other hand. Set
the needle cap aside for use later.
If the needle and the syringe
come apart — and they have not touched anything — simply put them
back together again. If the needle and/or syringe have touched
anything, dispose of them in your sharps container, and start over
again from Step 3.
5. Fill syringe with diluent
Place the vial of diluent on
your clean work surface.
Carefully insert the needle
straight down through the center of the rubber stopper into the
vial of diluent.
Gently inject all the air from
the syringe into the vial by pushing down on the plunger. (The
injected air will make it easier to withdraw the solution).
Without removing the needle,
hold the plunger with one hand and turn the vial upside down. Pull
back the syringe to make sure that the needle tip is below the
diluent level in the vial.
Pull the plunger to allow the

your work surface.
Insert the needle through the
center of the rubber stopper into the Humogen® vial. Slowly and
gently push the plunger, allowing the diluent to flow down the
side of the vial. Do not squirt the diluent because this will make
the solution foamy. If it becomes foamy, let it sit until the
bubbles disappear and the liquid becomes clear.

10. Pick an injection site
Find a place on your body where it will be easy for you to give
yourself the injection. Recommended areas include the top of the
thigh and either side of the navel. Make sure to change the
location of your injection each day so that one area does not get
injected too many times.
Before you inject, take an alcohol swab and
carefully clean a four-inch square area around your injection
site. Throw the swab away and let the skin dry.
11. Inject Humogen® [somatropin
(rDNA origin) for injection]
Hold the syringe in one hand and remove the cap from the needle.
With your other hand, gently pinch a three-inch
fold of skin.
