Have a rotten odor from years of UTI ...allergic to sulfa, so have been taking Cipro for a long period of time.  Now after only one pill or even a half of one, I will get painful mouth ulcers under my tongue and on my gums.  Odor is causing me great discomfort.  I take multiple showers to function and be around public.What to do?   One pill kicks the odor and infection..just cant stand the side effect.
Thanks for your query, I have gone through your query. The ulcers could be because of the allergic or hypersensitivity reaction to the ciprofloxacin like allergic dermatitis or plasma cell gingivitis. Consult your physician and ask for a substitute Chat Doctor.  For the ulcers take topical steroids like triamcinolone acetone (0.1%) 4-5times daily for 1 week. You can also take topical anesthetic and analgesics like Anabel gel for the pain. You can rinse your mouth with mouth washes like either. Consult an oral physician to rule out other possible causes of ulcers and halitosis. I hope my answer will help you, take care.
