Gonal-f is administered by subcutaneous injection. However, the preparation of the injection will depend on the format in which Gonal-f is found.
For the injectable solution, it will be necessary to mix the powder with the solvent to reconstruct the drug. In addition, the Gonal-f pen is already pre-filled and only the necessary dose needs to be selected.
Normally, Gonal-f is applied only once a day and both its dosage and the time it is administered are reviewed by the specialist who carries out the stimulation treatment in order to achieve the desired response.
