Sadly, I don't have an answer for you. My
Lortab ITSELF smells like citrus.
I have had a similar experience with getting injections of Ketelorac Tromethamine. (Sorry for the spelling. The brand name is pronounced "Tordol", and I know that's not how it's spelled either.) Anyway, any time I get an injection of this particular drug, I get a very odd taste in my mouth. It's almost an antiseptic taste...it's quite hard to describe. No doctors or nurses have ever heard of this happening until I mentioned it.
