Please refer to the product insert which can be found in the medication box, for instructions for use of your specific insulin pen / penfill.
Store unopened insulin in a refrigerator between 2 to 8 degrees Celsius. Do not freeze. Do not keep insulin in a hot place (e.g. in a hot, closed vehicle, on top of a television set) or expose it to heat or sunlight. Insulin that is exposed to direct sunlight for too long may give it a yellow-brown colour. Do not use the insulin if this happens.
Once the insulin is in use, it no longer has to be refrigerated, but should be thrown away after 4 weeks (Lantus) and 6 weeks (Toujeo).
Keep this medication out of reach of children. Throw away all expired medicines.
If used at home, you may throw this injection away along with the used needles, into a metal tin, or glass jar or thick plastic container (e.g. detergent bottles) to prevent any needle stick injury.
