The delivery method of some drugs may be phased out or changed for a few reasons—sometimes a change might be required, like when CFC inhalers for asthma were found to be bad for the environment and replaced by the environmentally friendly HFA inhalers. Manufacturers may also find a better way to deliver their medication that makes it easier to use, and discontinue the older version.
Levemir is a long-acting insulin for type 1 and type 2 diabetes. It is currently available in vials, FlexPens, and now FlexTouch pens.
Why is the FlexPen being phased out?
The FlexPen is being phased out because the manufacturer Novo NorDisk has come up with a new pen design, the FlexTouch, which is easier to use.
What makes the FlexTouch Pen different?
The new FlexTouch pen has no push-button extension, and instead uses a unique spring-loading dosing mechanism.
On other pens, the higher the dose, the more the push-button will extend out of the pen, making it more difficult to push to inject. On the FlexTouch, no matter what the dose, the button does not extend, making it easier to push.
Which pen needles does the FlexTouch pen use?
Are there any other similar long-acting insulins?
Both the SoloStar and FlexPen have the dial-in dosing with push-button injection. If you have a high dose and are looking for the non-extending push-button, Levemir will be your only option for the time being.
