Hi Jenny. I only know that Janumet is a combination of the frequently prescribed drug
metformin and another one. This combo pill helps the body control blood sugar in type 2 diabetics. The warnings are that this is not for people with liver or heart problems. I think the pharmacist must tell the patients of these warnings, just as you can read the product inserts yourself. I think all drugs can have side effects and that we have to be attentive to odd reactions in our bodies
just in case.... So, if I were put on Janumet, I'd be sure to measure my blood sugar regularly and notify the doctor if I have any questionable side effects, but I think the pharmacy is just doing its job and giving your father information about
the drug. You can look at several websites for more information:
