What needles to use for Saxenda?

The manufacturer of the drug recommends using needles up to 8 mm long and from 32G thick. Please note that the length is given "up to" 8 mm, i.e. it can also be shorter needles (but not longer than 8 mm). You can use 8 mm needles, but also 5 mm or 6 mm. Patients often use 5 or 6 mm - this is enough length to administer the drug subcutaneously. It is worth checking several sizes - choosing between 5 - 8 mm with the correct administration it will be possible to properly deliver the drug. Other aspects are your "preferences", i.e. whether when using shorter / longer needles, the injection hurts less. 5 mm, e.g. https://www.gdziepolek.pl/produkty/48855/igly-do-penow-bd-micro-fine-plus-igla/apteki 6 mm, e.g. https://www.gdziepolek.pl/produkty/54708/novofine-igly-do-penow-insulinowych-igla/apteki 8 mm, e.g. https://www.gdziepolek.pl/produkty/61649/insupen-igly-do-penow-pic-indolor-igla/apteki After each administration of the drug, it is recommended to change the needle. It is best to do it in such a way that before administering the drug, we mount the needle, administer the drug, remove the needle and put the cap on it, throw it away. We store the pen without a needle. Before the next application, we put on a new needle.

Hello, the links sent to the needles are for needles less than 32g thick and the manufacturer recommended above. Can you use, for example, 31g to serve Saxenda? I can't find 32g needles and if they are hard to find 4mm 32g is it not too short?

Do@Martyna:
There is no need to check the flow after each needle change. According to the manufacturer: "Always use a new needle for each injection. This can prevent needle blockage, contamination, infection, and inaccurate dosing." "When using a new pen, before the first injection, you should always check the flow."

Both a 5 and 6 mm needle will be suitable.
