New KwikPens - no extra dose!

The new KwikPen design removing the extra dose is a real change for people who relied on that fifth draw. The leftover pens are worth holding onto if you are still using the old format. The generous offer for NL folks makes sense given the timing.

The overfill is there for manufacturing tolerance, not as a bonus dose. 0.5mg extra at the end of a 2.5mg vial is a 20% overdose, not a freebie. The new pen design removes the ambiguity about where the plunger stops, which most people will find less stressful than the current guess.

The waste calculation on kwikpen versus syringe is a real consideration when you can see the residual - the syringe-for-the-last-dose approach trades precision for recovery of that residual. How much it actually matters depends on the price point.
