I have the same issue, where I'll be high for about 4 hours after a pod change. It doesn't happen all of the time though, so it can be frustrating. I always try to give myself a little bolus before the change (about 1/2 hour's worth) and will also adjust my next bolus for a meal up by 20% if my reading is high before the next meal. I usually change between breakfast and lunch and am stable again by dinner time.

Thanks Dan! Will try to change my "change pod time" so it's not before bed. This way I can increase the next meal bolus and see if that works!

Hi Gina,

I've had this problem too. I solved it by giving a bolus AFTER the pod change. Whenever I remove a pod, there is always a little droplet of insulin where the catheter was removed, which means I'm losing some of my most recent bolus and/or basal. Depending on when I make the pod change, relative to meals, I'll usually bolus 1-2 units right after a pod change. That is usually sufficient to fight off the post-pod change highs.

Another option would be to do your pod changes in the morning. Then you could aggressively treat those highs without the worry of overnight lows.

Good luck and cheers, Mike

Thanks Mike! I will do the bolus afterwards from now on and see if that works. Duh, totally makes sense as i have the 'droplet' too :)

We usually do pod changes about 4 pm. Most times I give 1 unit before changing. We treat highs more aggressively at dinnertime after a pump change with a higher correction rate. We do another check at 8pm or so before her bedtime so that we can see if she is going high, if she needs a correction, and if we need to skip bedtime snack.

She's 6 so we may be doing things a little differently.

Thanks Leighann. I'm totally willing to give it the 6 year old try as it sounds like you guys have it under control--which I'm striving for :) Thanks again!

For my 13yr old daughter, we are doing a 0.5unit pre-change bolus, then a temp basal on the new pod of +30% for 2hrs. We do the change just before dinner. Works sometimes and not others depending on what and when we have dinner. Would like to tweak this routine and thinking about a higher bolus with a longer smaller temp basal.

Would love to do a poll of this group to learn more about 1) pod change times (time of day, pre or post meal), 2) On which pod to do the pre-change bolus (old or new), 3) typical bolus dose, 4) typical temp basal amount and time.

Thanks AML for the info. Would love to see results of that poll too! Well for me: 1)change time is after dinner prior to bed usually around 9pm (though I'm trying to move it earlier, but ALWAYS forget!) 2) I was doing the bolus prior to change, but will now try after, 3)typical bolus: 1 to 1.20 units, and 4) I haven't really done a temp basal in this scenario, but should probabably try it. Thanks again!

Gina,
The other tip people gave us is to leave the old pod on for a short time after the change bolus (we wait at least 15min after bolus before deactivating) and after deactivating (at least 5min). That way it addressess the residual "drip" that you and others refer to....or so we hope. Best of luck to you.

Excellent tip! I don't notice the residuals as I have it on the back of my arm, but this makes perfect sense.

I wonder if Insulet acknowledges this issue. I can only guess it takes a few hours of insulin flow to dislodge bits of tissue that sometimes block the cannula after insertion? Maybe the cannula sometimes fails to go in straight after insertion and the curvature of the cannula gradually straightens as insulin flows through it?

Great point. Makes sense to me, though I'd lean towards the idea that they don't acknowledge this? Or it probably depends which person you get on the other end of the line when you call in ;)
