Frequently asked questions
More questions about Genotropin®.
Can the listed 5.3 mg Genotropin cartridge be used in the U.S. Genotropin Pen 5?
Device compatibility should never be assumed from similar numbers. U.S. labeling specifies a 5 mg cartridge for Genotropin Pen 5. The 5.3 mg presentation requires verification against the exact product and compatible device.
Does Genotropin require a prescription?
Yes. Genotropin is prescription-only somatropin.
Is the 5.3 mg presentation the same thing as the U.S. 5 mg cartridge?
They are market-specific presentations of the same brand, but the labeling is not identical. The dispensed product should match its local label and prescription.
Is Genotropin “synthetic HGH”?
It is recombinant human growth hormone: somatropin produced using recombinant-DNA technology.
Why compare Genotropin with other HGH brands?
The active ingredient may be the same, while device design, concentration, presentation, excipients, market availability and price can differ.
