I have been using the Tandem tslim for over a year and a half. My latest shipment contining the cartridges, syringes and needles included Excel needles and syringes. Up until then the box always contained Becton Dickenson needles and syringes.
I did not think anything of the change until I started using the Excel needle/syringe. I find that loading the cartridge now requires a much greater amount of pressure. There always was some resistance but now I really need to press very hard to get the insulin in the cartridge.
Then today one of the needle/syringe leaked terribly. One might think I did not tighten the needle on the syringe but this was not the case. The leak was where the needle and syringe meet but was very tight.
SO my question is, have others recevied the Excel needle/syringes and if so, have they had any problems with them.
I wonder if the BD syringe/needles were substituted with Excel because of the hight demand of BD needles for Covid injections. If so I wonder if Tandem will go back to the BD syringe/needles.
