Pregnancy Today's Health Advisory Panel Answers:
I'm allergic to lidocaine. Will have an adverse reaction to an epidural?

Question

I just read that the drugs given in epidurals are from the –caine family. I'm concerned because in recent years I've developed a severe topical reaction to drugs such as lidocaine when used topically. I'm worried that I may have some allergic reaction to one given in an epidural. My doctor said to talk with the anesthesiologist when I deliver but I truly don't want to wait until then. One more note - I used to receive novocaine as a child without any problems but I haven't had novocaine in over ten years and this allergy has developed just in recent years. I would appreciate any advice on this matter. Thank you! – Kathy, Grand Rapids

Answer

It is true that the local anesthetics used in epidurals come from the -caine family of drugs. I think it is definitely a concern that you might have some sort of allergy to these medications which might prevent their use when it comes time for you to have an epidural. In addition, I think it is a great idea to talk to your anesthesiologist in advance to come up with a plan of action.

Having said that, let me tell you that true allergies to this family of drugs is extremely rare. This is not to say that you do not have an allergy, only that it is very uncommon. It is much more likely that you have developed an allergy to something else in the topical solutions - some type of carrier chemical or something added as a preservative. When used in an epidural, these medications do not have any additional chemicals or preservatives. The only way to know for sure would be to get yourself tested for an allergy - and you may need to do this if you want to be sure you can receive these medications.

If you do indeed have an allergy to these medications, you can discuss your options with your anesthesiologist. Options include utilizing another form of pain relief such as intravenous medications, intrathecal narcotics, etc. or trying to use an epidural while avoiding these medications (using narcotics only or using local anesthetics of another class). So, these are my recommendations - try to talk to your anesthesiologist in advance, consider formal testing to find out if you have a true allergy, consider other options for pain relief if you really do have an allergy.
