Can tramodol or metoprolol affect glucose tests?

My husband is a type 2 diabetic, but also has HBP & heart problems He is on a beta blocker too called atenolol. It also lists diabetes, but his doctor insists he take it anyway. When his glucose levels became unstable the doctor increased his glyburide to 10mg twice a day, instead of once a day, but they still remained very high at 240 or so, so I suggested that they add metformin 500mg to the mix, & it has brought down his glucose levels to normal again. Sometimes it takes a bit of detective work to find the right mix. The FDA had just put out an article that glyburide & metformin together gives greater control of glucose levels & it worked for my husband. Do you see an endoctrinologist or just your PCP? It might be worth your while to suggest these two drugs.(uness you are type 1 & take insulin)Good luck to you...

I'm assuming you're a known diabetic. In that case, the doc should have known better, since metoprolol literature cautions use in diabetes.

Yes, metoprolol can cause unstable diabetes. It can cause blood glucose levels to fluctuate. Fluctuating glucose levles can also happen when a person is under stress or getting an infection too. Speak with your Dr. Dont just stop metoprolol. that can be dangerous. If it needs to be discontinued, it must be withdrawn slowly but get your Drs advice first.
