Is there a site where I can ask about the interaction between prescription drugs? Also, I want to know if there is any problem using metformin plus prandin -- and an occasional insulin injection of novolog. I stop the metformin when sick (i.e.: flu) and before a CAT Scan. However, what about using an occasional novolog injection with prandin + metformin. Or novolog with just prandin alone. I only use the injection when blood sugar is way high because of overeating--which I know I should not do!! Thank you.

If you go to the main Drugs.com website and click the link in the top middle of the page titled "Drug Interactions Checker" you will be able load a list of the medicines you are taking and check if there are any interactions.
