Allergic reaction to sulfa antibiotics

[lovinghands]

my dtr. used to take bactrim for her ear infections until one time she had a sandpaper rash covering her abdomen. her pediatrician labeled it an allergy. now is it true that people that are allergic to sulfa, cannot take lasix?

When I was 15, I was prescribed sulfa for an UTI - I have a hx of anaphylaxis with penicillin. Within 2 hours of taking the sulfa I developed muscle twitches, chills and mild cyanosis. My mom nearly had a cow as she remembered my reaction to pcn when I was a toddler.

I have never heard of a problem with lasix but have heard that people w/ pcn allergy can be hypersenstive to cephalosporin and sulfa meds. I am very cautious about antibiotics I am prescribed - some docs are great and others are just plain careless.

People who are allergic to sulfa can have a sensitivity to any of the sulfa-based drugs, including Lasix. I found out the hard way that Celebrex (NSAID) has sulfonamides in it. I am allergic to sulfa and when I took a sample dose of Celebrex that the doctor had given me, I developed hives and a swollen face. If you go to Google and type in "lasix sulfa allergy", there are all kinds of links to articles that explain the cross-sensitivity.
