No, not with prescription medication. Every state allows an officer to testify that someone is impaired by virtue of how they are acting, etc. There are no specific blood limits that apply. You can ask your doctor about it and express your fears and he can certainly tell you what limits he would consider to be impaired and what limits your blood is likely to show at those dosages.
Realistically, if a doctor comes into court
and says that he prescribes those doses and you wouldn't be impaired then a judge or jury is going to believe the doctor.
Thank you for allowing me to assist you. As you know, we work on the honor system here and cannot always provide you answers that you like. I believe I have answered all of the questions you asked so I would request that you please click the ACCEPT button so I receive credit for my work and leave feedback if you have a chance. Please consider clicking "BONUS" as a nice way of saying "thanks" for a job well done, although this is neither required nor expected. I believe in giving information that is to the point, but please remember that I can only base our answers on the information you provide and sometimes a misunderstanding as to what you are looking for or already know occurs so feel free to ask additional questions or for clarifications.

Several customers have asked how they direct a question to me in particular. If you specifically want me to provide information for you just put “FOR JD 1992” in the subject line and I will pick up the next time I am online.
