Any Saxenda pens that haven't been used should be kept in the fridge. After being used once, you can keep the pens either in the fridge or at room temperature.
Open pens must be thrown away after 30 days even if they have any treatment left in them. Pens need to be disposed of in sharps bins – you'll be given one of these when you start using the treatment.
We'll let you know how to get rid of the sharps bin and its contents when you're prescribed treatment.
