On cefadroxil for 1 week for a staph infection on my face. Just noticed it contains sulfa. Have a severe allergy to sulfa. Ended up in ER Thurs. AM. Severe nausea. Can I sto the Meds now ? One week left to go. Cant take the nausea anymore !  I was told years ago never to take sulfa again due to a severe allergic rash allover body. Happened twice. Bruises and bleeding everywhere from scratching.
