[|Human|] I used lidocaine topically a number of years ago and my face swelled up, had to go to doctor to get a shot to reduce swelling. Went to the dentist today. Had to have two cavities filled without anesthetic. If I am allergic to lidocaine, are there alternatives to use?
[|AI|]  Thanks for your query. I have gone through your query. If you are allergic to lidocaine, you can get the treatment done under other local anesthetic agents like bupivacaine or anticline. Most of the time people will be allergic to the preservative(methyl paraben) used in local anesthetic agent not the lidocaine. So you can use a local anesthesia without the preservative. Or you can get a test dose done to find out whether you are allergic or not. I hope my answer will help you. Take care.
