Prescribe by brand. A biosimilar medicine is a biological medicine that is highly similar and clinically equivalent (in terms of quality, safety, and efficacy) to an existing biological medicine however they cannot be considered generic equivalents of the originator biological medicine. Because they are not identical, biological medicines must be prescribed by brand. The decision which brand to prescribe rests with the responsible clinician in consultation with the patient. Automatic substitution of brands at the point of dispensing is not appropriate for biological medicines.
Teriparatide is available as Forsteo, and the biosimilar products Terrosa and Movymia. All products are the same strength and have the same licensed indications, however Forsteo is a disposable pen device whereas the two biosimilar products are re-usable pen devices with replaceable cartridges. Terrosa and Movymia cartridges must only be used with the same brand re-usable pen devices. Patients should receive training on how to use their specific device.
