How Long do Novocaine's Side-Effects Last?

Hello,

I hope this is the right forum for this question, as I am new here!

I'm having an anxious reaction from my visit to the dentist yesterday. He gave me Novocaine (probably Lidocaine) to prepare my bottom molar for a crown and my heart started racing. As I have nervous tendencies to begin with, that probably made it worse and I had to ask the assistant for a cold cloth for my head. The sensation passed and he did the work, but then I couldn't sleep last night! I was out of the dentist's office by 1PM, could it have been the epinephrine in my system still? Or was it just coincidence and I just had a bad night?

So, now, because of that I'm worried it'll happen again, when I go back to get the rest of the work done in 2 weeks. I plan to ask him to use "non-epi" novocaine this time, but just in case, and for the sake of knowing...

...how long could the effect of epi have lasted?

Thank you!

Depending on how exactly the epinephrine got into your system it lasts from 2-10 minutes.

Usually no need to avoid but just to be careful

Wow, that's it? So, it's not like a drug that may stay in your system for hours? Then, I guess, that could not have caused my bad night! I think I may still ask for "epi free" numbing next time, but it's reassuring, anyway. Thanks for your response! :)

I tend to ask for epi-free myself due to my anxiety issues (it makes my heart palp about like crazy, not really a sensation I like when I am already freaked out even though it always settled after a minute or two), tbh my last dentist didn't even give me a choice, he was like, 'I know you have anxiety, this is a little better for people with that' and that's how I found out there's ones without epi to begin with!

Anyway, re: your bad night, I don't know about you, but after a stressful situation I am often a mess the whole day afterwards. That may have contributed to your sleepless night, your body may have just not settled down after everything.
