1.1: Does the new doctor know what non-prescription medicines you are on?
2: Is your current prescription medication regimen working?
3: If it is not, then bring that up with them.
4: If you think it is working, explain that as well.
5: If your new doctor thinks your current regimen is outdated, they may change the following: dosage, prescription brand, etc.
6: If you are on more than one prescription, they may try to get that amount down as well.
Just be honest about whether the medications are working; it may also be wise to tell them about any non-prescription medicines to avoid interactions.
Also, if you are having side effects from your current regimen that are unacceptable, speak up about that.
I am not that smart, so take this for what it is worth, and if it has already been discussed, then ignore it.
