Frequently Asked Questions

General questions

While there may be an occasional “pinch” when inserting the set, many people find inserting infusion sets more comfortable than giving injections. Once the set is under the skin it is so comfortable that most people forget that they're wearing it.

In order to help keep sites free of infection, we recommend that sites be changed at least every 48 hours for steel needle sets and every 72 hours for soft cannula sets. It is important to always test your blood glucose level 1-3 hours after inserting a new set, to make sure that it's functioning properly.


Pain at the infusion site may be a sign that you are using a set which does not penetrate at the right depth for you (this can especially affect children or thin users). For 90° insertion sets, talk to your physician about the possibility of switching to a different needle or cannula length.

Water sports and heavy sweating can affect the infusion set’s adhesive pad – try using an extra water-permeable adhesive patch (like Tegaderm™ or Opsite™ IV3000™) to give your site extra security. Sandwich technique: Cleanse the skin using an adhesive wipe, allow to dry, apply a sterile dressing, insert the set into the dressing, cover the set with another sterile dressing to “sandwich” the infusion set. 

The use of hypoallergenic materials is a high priority for Roche. Our infusion sets are latex- and PVC-free and glues and solvents are used as little as possible. The adhesive tape is also specially designed to allow the skin underneath it to breathe. Adhesive tapes have been qualified by comprehensive biocompatibility testing. However, allergic reactions can never fully be ruled out. Sometimes they develop suddenly, even if you have used the same product for years. If an allergic reaction should occur, ask your physician about products that can help you continue a comfortable therapy.

The Accu-Chek infusion sets offer a Luer-lock connection that meets international standards and is widely used in medical engineering. Our sets fit on all Accu-Chek insulin pumps except the Accu-Chek Insight insulin pump. Our sets fit on all other insulin pumps that meet the same standard.

The disconnectable Accu-Chek infusion sets allow you the freedom to disconnect from your insulin pump altogether for the duration or your activity. Talk to your physician about time off the insulin pump for sports or an occasional day at the beach.
