Yes, Gonal-f should be stored at 2°C to 8°C (do not freeze) and protected from light (store the pen with the cap on to this end). In case refrigeration is unavailable, the Gonal-f pen can be stored below 25°C for up to 3 months. After piercing the Gonal-f pen with a needle for the first time, it may be stored below 25°C for up to 21 days, though.
