The most striking side-effect has been a VERY bitter taste in my mouth day and night (worst at night). It is exactly like bile (I know from morning sickness days!). I had a headache for the first 3 days on Biaxin, esp bad at night. I experienced hand tremors for the first few days as well for which I have no other explanation. I have had considerable intestinal gas and discomfort and on the 7th day of treatment acute stomach pain for a couple hours. But there has NOT been excessive diarrhea nor any obvious yeast infections. This was my greatest dread.
I am glad to say good-bye to this drug after 7 days of treatment. It did seem to take care of the low-grade fever associated with bronchitis. And my coughing is reduced though not gone yet. My throat/voice box area feel swollen at present. Not sure if this is the drug or the coughing.
Having said all that, I would cosider using Biaxin again, if only to avoid yeast infections!
