I was started last Thursday for sinus infection. I ended up in ER on Sunday with what I thought was a migraine headache with nausea and vomiting. Which I have a history of. Thank God the doctor on call did not give me the normal shot which I usually get and send me home. He was did blood work and found out the my liver function test was so high that it was not safe for me to go home so I spent two days in the hospital to get my liver functions back to safest enough level to send me home. And they are not normal yet. So be ware of this meds or any meds that it is related to
