Prader-Willi Syndrome (PWS)

Deaths have been reported with the use of growth hormone in children with Prader-Willi syndrome. These children were extremely overweight, and had breathing problems and/or lung infection. All patients with Prader-Willi syndrome should be examined for these problems. They should also establish healthy weight control.

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.
