You may be wondering, why would you want to switch to insulin pens if you’re already on an insulin pump?!
Valid question. There are actually many scenarios in which an insulin pen is a little bit easier to manage than a pump.
These include, days trip to water-parks, chilling in the hot springs, mud baths of Chile, Vietnam and Iceland (among many others), a day at the beach, swimming, surfing or you simply want a pump holiday/vacation.
There are other “medical” reasons why you might need to make a temporary switch. These include:
Life with an insulin pump can sometimes get a little overwhelming. Not everyone enjoys being attached to something 24 hours a day, 365 days a year, so there is really nothing wrong with taking a little break and enjoying the “freedom” of injections. I’ve gone without my pump for 4 days at the most, but I often switch to insulin pens if it’s more convenient, i.e at the particular events above.
The important thing to remember that when you are making a switch, the chances are, you are going to need more insulin via pens than you have received via an insulin pump. This is because the insulin pump has been fine-tuned to the hour of what doses your body needs. You simply can’t get that same consistency from an insulin injection, so you usually need more to get the same effect.
Also remember that fast-acting insulin has a short lifetime. Most typically peak and finish around 4 hours (depending on the brand of course), but this means you’re going to get your background insulin too.
Don’t be mistaken and think that your background insulin dose should simply be the total of your background basal rate from your pump. That won’t be enough (on most occasions), this is why it’s important that you should discuss the switch or holiday with your diabetes specialist nurse before you actually do it. They can advise you on how much to increase your insulin by and what precautions to take.
I’ll give you advice on how I do it. This isn’t medical advice, it simply works for me. But this is under the advice from my diabetes specialist nurse beforehand. Below are some tips and guidance on how to switch from an insulin pump to pens.
This is suitable for those days when an insulin pump is inconvenient, such as surfing, swimming, at a water-park etc.
The duration is typically 24 hours or less. In this case, you need to give your short-acting insulin every three to four hours. Depending on the “life” of your insulin.
If it literally a case of, you’re at the water-park from 9 am until 5 pm, then don’t give yourself any background insulin in the form of “Lantus”, this is because these insulin typically last 24 hours, and you will have to wait until that is out of your system before you can safely put your insulin pump on without risking a hypo.
So, to conclude….follow these steps for less than a day of pump removal
Once your day of fun is finished, you can pop your insulin pump back on. Make sure the last bolus of fast acting insulin is out of your body. i.e, wait 3-4 hours from your last bolus before you return the insulin pump to your body.
Anything longer than 24 hours is going to require background insulin, so it’s considered a long-term switch. This is for those who are taking a “pump holiday”.
There are two main options for this type of switch:
If you do not have access to a doctor before you make the switch, then for your background insulin dose, you should simply calculate the total basal rate on your pump and give that. This may not be correct, but if it’s only for a short period of time, it’s not the end of the world.
Regardless of whether you are choosing to make a switch to insulin pens, you should always carry insulin pens as a precaution for you whilst traveling. An insulin pump is still only a piece of technology and it can’t be completely relied on (like all technology!) so it’s good to be aware of how to make the switch in the event your insulin pump dies.
