Roltesim is simvastatin, a type of cholesterol lowering medication. It does not affect your blood glucose numbers. It helps protect from heart disease.
It is not a diabetes medication.
Your numbers are still high and need to be controlled better, by what you put in your mouth and by what you don't put in your mouth.
What diabetes medications are you taking. Be detailed.
What are your blood glucose numbers, before meals and 2 hour numbers.
Apparently you are taking the big 3, metformin, sulfonureas, and insulin.
You need to do some of the heavy lifting. Some of the work and slowly cut back on your carbs. Are you gaining weight.
You should see some results if you slowly cut back your carbs to 1 serving per meal (so you can adjust your insulin dosages slowly), 15 carbs:
1 slice bread, or
1/3 cup potatoes, or sweet potatoes, or rice, or grains, or pasta or
1/2 to 3/4 cup corn, or beans, or peas, or pap.
Insulin helps metabolize glucose into energy for our cells.
Any carbs that we don't use for daily energy is stored as fat for use during famine times.
Good luck.
We need to eat to our blood glucose meters and the nondiabetic range of 4.0(72 usa) to 7.8(140 usa).
This will arrest cumulative vascular damage from glucose spikes now. Glucose spikes feed diabetes complications and comorbidities.
Again good luck.
Glucose still out control. Treat the root problem
