The strength of Humulin R and Humalog are basically the same, therefore you should not need a change in dosage. However, the rate of absorption and action are quite different and may necessitate a change in how you USE the bolus features on your pump.

Because Humulin R takes up to 30 minutes to start working, it should, ideally, be taken a full 30 minutes before meals. This can be a challenging feat, one which might best be achieved by setting a timer, such as the "alarm clock" feature in your insulin pump, to remind you when it's getting close to dinner time. Taking the insulin closer to, or even following, your meal is still considered an option, but one which will almost always lead to difficulty controlling post-meal BG levels.

Because Humulin R has what they call a "longer tail", it lasts significantly longer than Humalog, and could potentially lead to low BG levels if your "food action" wears off before your "insulin action".

In short, you'll want to test your blood sugar more often as you adjust to this new type of insulin, learning for yourself how it will affect you. Work with your doctor or Certified Diabetes Educator until you are comfortable with any new formulas or changes that are needed. Hang in there!

Are you sure that it was Novolin R and not NOVOLOG that you were switched to? When the pumps were first came into use in 1982 (when I was offered one at UAB Medical Center), the insulin used was buffered Regular, called Velosulin, and marketed by Novo-Nordisk. This was replaced by the genetically-engineered- organism produced Novolin R, so there is much literature on its use,and Novo-Nordisk will send both you and your medical practitioner this information if you ask for it. When I started using a pump, and had been using Humalog (in pens) because I responded to it better than to Novolog, my CDE at Kaiser-Permanente had me use Nolovlog in the pump because it is less affected by heat and ambient conditions than the Humalog, and has been tested in a pump reservoir for up to a week at normal body temperature. In an area like Sacramento, where afternoon highs of 100+ are the norm in the summer, this is an important factor! Whether you will need to change your pump settings is so very individual, that you will just have to carefully observe how your body reacts to it. If your insurance will cover a short-term CGM (like for a week) you can get a lot of data that way. Please remember, though, that changes in your insulin needs are not indications of "failure" or non-compliance with the program, only that something has changed in your life. You didn't indicate your gender, but if you are female, and have ever been pregnant, you've been there and seen how you insulin requirements can change dramatically!If you're a guy, well, the changes throughout your life haven't been quite that dramatic (to your diabetes) but you still change as you age. I've been an insulin junkie since 1967, and I can tell you from my life experience, that the need to change is a certainty. Don't let it scare you. XOXOXO
