thank you for your query.
It is a very common side effect of Betnesol
injection to have your sugar levels shoot up.
However, 206 is really high.
For the time being, you should consult your doctor, and measure your blood sugars on a 6 hourly basis.
If required, insulin
short term could be added till your schedule of Betnesol is over.
Do not worry, as this is a transient side effect of steroids
As long as you have not been diagnosed as having gestational diabetes
mellitus so far, no long term effects will remain.
Consult your obstetrician for detailed guidance.
