Lidocaine Allergy In Children
Other meds available: Find out if you are truly allergic to Lidocaine by seeing an allergist soon. True allergy to Lidocaine is rare; you may have had a reaction to Epinephrine if it was added to lidocaine. There are other local anesthetics such as bupivacaine (marcaine) or ropivacaine that can be used instead of Lidocaine for spinal or epidural anesthesia for labor and delivery, or to numb the skin for episiotomy. ...Read more

Anesthetic allergy: Allergic reactions to Lidocaine and other local anesthetics are fairly unusual and very rarely serious. Most "reactions" turn out to be a toxic reaction due to dose or inadvertent injection into a blood vessel. Allergy skin testing is available to Lidocaine and an allergist can perform this. With different classes of local anesthetics, it is usually pretty easy to find an acceptable substitute. ...Read more
Can HSV2 swab tests be falsely positive? I broke out in blisters after using Vagicaine and found out later that lidocaine allergies run in my family.
Not likely: With the most common tests (PCR test for HSV DNA or viral culture) a false positive result is very unlikely. If you have had a positive swab test for HSV2 from a genital lesion, you have genital herpes. And lidocaine allergy is unlikely to cause herpes-like lesions. If this is a new infection, you should be on treatment with acyclovir or valacyclovir. Discuss with your doctor. Good luck. ...Read more
I have a true, tested allergy to xylocaine (lidocaine). I've used carbocaine ok for years. Could I develop an allergy to it as well? I need some major dental work and I always worry that I will have a reaction.
Local Anes Allergy: It is always possible to develop an allergy but the likelihood is extremely small. I have never personally heard or seen a patient allergic to Carbocaine.

If my scalp & skin was itchy after lumbar puncture, which is that- an allergy or a side effect of the lidocaine injected in my back?
Hard to know: And it could of course be unrelated or be a result of whatever it was that prompted an LP. However, if you had rash/itching on your scalp, it is more likely to be some kind of allergy rather than just a local reaction. So be careful and remember to tell the dentist or doctor next time you need a local anesthetic. They could use another one besides lidocaine. Good luck! ...Read more

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.

"Doesn't work"?: Hard to understand why Lidocaine "doesn't work" for you. Did you have it for a nerve block (dental, regional anesthesia, spinal, or epidural)? Did you use it on skin? Was it injected to numb an area for surgery or to drain an infection? In most of these scenarios, it is usually other factors that cause failure to archive numbness - not a resistance to lidocaine. ...Read more
