Thanks for writing your query.
can be caused as a side effect of the medicines you are taking (metosartan and janumet)
Moreover dizziness can be caused by sudden fall in blood sugar or blood pressure.
I would suggest that you should get your blood sugar tested and blood pressure monitored when you are feeling uncomfortable.
If the recordings are showing decreased blood sugar or fall in blood pressure, you should consult your treating doctor to adjust the dose of the medicines according to your needs.
I hope this is helpful to you.
