At 10 am I was given Rocephin IM with Lidocaine 2 ml as a pain prevention for the shot. It was not on my electronic medical record that I am allergic to Lidocaine. Within 10 minutes I was given Benedryl IM plus a steroid IM. I have an epi-pen to use if needed. My doctor has also called me at home to make sure am ok. At 4:30 pm still some mild numbness on tongue, back of throat, lips. How long for that 2 ml to work it's way through my system?
Thanks, Christine
Hi, welcome to Health care magic forum.
You was given Rocephin and lidocaine I.M. so you had the numb ness of the tongue , lips, and throat is there.
The numbness is not the side effect of the lidocaine , it is the effect of the drug. As it is given I.M.the effect may last for longer time . how...

Hello, I've been told that I am allergic to lidocaine. When I had a shot of lidocaine mixed with cortisone, my skin turned red and very warm. I'm going to have oral sugery in a few weeks and I told my doctor about my reaction; so he decided to give me a couple of lidocaine shots in my mouth to see if I had any kind of reaction. Well I didn't right then, but a few hours later, my mouth was throbbing and it felt as if all my teeth were going to fall off! Is this normal? Should I ask to be completely put under for oral sugery? As if now the plan is to use lidocaine shots and laughing gas....
Hi,

Thanks for asking the query,

Take an antiallergic drug under the prescription of your Physician.
At home take lukewarm saline and antiseptic mouthwash rinses.
Also take a painkiller.

Take care!

I take 300 mg of Lithium twice a day. I tried the 5g or mg of LIdocaine ointment for neuropahty and got dizziness upon lying down and turning my head. I have experienced a slightly shakyfeeling similar to tremors from Lithium also. But, I have not been sleeping well with back problems and nerve pain really wipes me out.
Do I just have Kaiser put it in my log not to give me this Lidocaine? The dentist says his anesthetics are not a problem as they are small and local and do not get into the bloodstream. Thanks. Judy
Hi Judy,

It is unlikely that lidocaine ointment is causing any such side effects, because on applying ointments, very little drug is absorbed into the bloodstream. Dizziness on lying down and turning your head is most likely due to cervical neuropathy or may be lithium related. Hope you are...

my friend has CRPS and recently (last week) went through 3 day out patient lidocaine Ketamine infusion treatment- which by all accounts were successful as her pain level is down, however, she seem to have spiraled into an unexplained emotional roller coaster. She has become confrontational with her husband and very argumentative, this behavior is not her- I have seen her over the past couple of days and she's shared with me why she's upset with him, but to me, the reasons are trivial and I believe that she is unaware of reality.... she is now texting me saying she doesn't understand what is happening (their arguing).... my question is, would the lidocaine/ketamine infusion create this type of irrational behavior as a side effect?
HI
Thank for asking to HCM
The short course of general anesthesia of course induces euphoria confessional state of mind, but that does not last long, it happen immediately as soon as patient comes out of the sedative effect, and vanishes within couple of hours, if this is not the case with her...

my son had dental extraction yesterday, about 28 hours ago. he has been very sleepy since after the procedure to now. is this normal? he was injected lidocaine 1st shot, and during the procedure, because he could still feel the pain, was given another shot. He is 9 y/o. about 44kg. thanks!
Hi
With your query, it is not common to feel sleepy after extraction. I think your son might be tired thats it nothing to worry about it. wait and see if he still feels sleepy after 2 days then visit your doctor. for an 44kgs boy two shots of lidocaine would cause any harm unless he is allergic...

do you recommend trigger point injections of lidocaine for muscular pain combined with physiotherapy for 16 year old daughter. she has done physio, acupuncture, and cupping and since last april when we were suddenly hit by a stolen vehicle by quite an impact from the rear. She has pain everyday. Takes maximum dose of vimovo each day.
hi

wish you good...

while injecting lidocaine with 27 gauge needle intradermally, as I pulled the needle out I kept injecting and some splashed back on my face and I feel into my right eye. Pt is hep c positive. No blood I could see, and no needle stick. Is there a known risk for this type of event for hep c conversion?
There is less chance of contacting hepatitis c But better to keep watch get blood tested after 6months repeat it after 6month.
