The dentist may use anesthetic such as 0.3ml lidocaine with 1:100, 000 epinephrine. Would this interact/ have problems with my heart or BP medication.

The dentist  may use anesthetic such as 0.3ml lidocaine with 1:100, 000 epinephrine. Would this interact/ have problems with my heart or BP medication.

That said I do try to error on the side of caution depending on the heart condition by not using the maximum dose( approximately 8 full injections) and breaking up multiple procedures over several appointments. ...Read more

Could lidocaine show on a drug test?

No: Some people think because it has "caine" in it that it could show up as cocaine, but it is a completely different chemical with no overlap with any drugs of abuse. Test kits do not test for it, and confirmatory tests like gas chromatography/mass spectroscopy will determine exactly what it is if there is any question on the screening tests. ...Read more
