Antibiotic Reactions
Question: I was recently dignosed with H. Pylori and was put on a
7 day regimen of Biaxin, Flagyl, and Prilosec. 3.5 days
into this I started experiencing severe dizzy spells. I
stopped the meds, but 1 week later I am still very dizzy and
the back of my head feels very tingly. Doctors opinions
are ambiguous. My personal physician wants me on Xanax and
the gastroenterologist wants me on nothing. He says the meds
are still in my system and need to wear off. I did see an
emergency room doc and he said the antibiotics should be
out of my system by now. I am 40 and otherwise in good
health. I did have complete blood/urine analysis and head
MRI-all normal.
Answer: I would have difficulty trying to find a mechanism to explain lasting headaches from the antibiotics. It is possible that your inner ear has been affected; but, this would be unusual with these drugs. They certainly are “out” of your system by this time. I would probably consult a neurologist about the “dizzy” spells.
