sinusitis
"Although there should be no negative drug interaction with this antibiotic and other medication I take daily, I had a severe allergic reaction: swelling of throat and tongue, vertigo and dizziness, bad taste in my mouth (even days after) and vomiting. I'm on my third day of the medication now and still feel sick and "weird". My throat and tongue are no longer swollen, but all my muscles hurt and my skin feels painful, also major headache and very sleepy. "
