"Easy-to learn and easy-to-use": Prefilled pen approved as a treatment for infertility

Known as GONAL-f RFF Redi-ject prefilled pen in the U.S. and originally approved by the FDA in 2013, the new version of the pen is easy-to learn and easy-to-use.

To date, an estimated 2.5 million babies have been brought to the world with the help of Merck fertility products and services. GONAL-f is the only gonadotropin that comes in prefilled, ready-to-use pen in the U.S. The new GONAL-f pen, like its predecessor, enables a fine-tuning of treatment allowing for minimum increments of 12.5 IU to titrate a wide range of doses and precisely target the dosing to patients’ needs. In addition, its new design features include an amendment to the dose display window for readability.
