Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, he can take oral hypoglycemic agents (OHA) (
metformin and
glipizide) and
insulin together.
No harm in taking both of them together.
And for his sugar level of 470, it is better to take both (OHA and insulin) together.
Along with OHA and insulin, he should also follow these for better glycemic control.
1. Avoid junk food. Avoid large meals, instead take frequent small meals.
2. Quit
smoking and alcohol if he has these habits.
3. Strict dieting after consulting dietician.
4. Regular
aerobic exercise like running, cycling, swimming etc.
Don't worry, with all these his sugar levels will be controlled.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
