Biaxin and increased heart rate

Currently on Biaxin XL on a 10-day medication for a Pneumonia infection. Experiencing: increased heart rate, sweating all day long with no fever “Chills” and a bad taste in my mouth.
A possible side effect that concerns me is I have been sweating “night and day sweats” all day long with no fever, since I started BIAXIN XL, I asked my Dr. and I was told sweating helps the body to get rid of bacteria but today is my 8 day of sweating, Strange !!!!
I have never had a problem with side effects in the past on any medication!!!
Anyone else experiencing sweating? Your comments will be appreciated!!!! Thanks,

Being a registered nurse, I know that all medications have potential for side effects. And with this type of forum, it is important to know that people who do not have side effects often don't write in BLOGS so there is a very biased view of the totallity of effects. Having said that, I've been on Biaxin XL for 4 days. This medication has really messed with my stomach since day 1. Starting day 2 was the night sweats and vivid nightmares. Nighmares puts it lightly- it was more like night panic. Day 3 started with diarrhea. So now I'm at day 4 with all my sweat, shakes, nausea, cramps, diarrhea and I can't wait to go to bed to have more nightmares. What can happen to me next?

first night on biaxin, had increased heart rate, 100 resting. I woke up in the middle of night last night with severe metallic taste in my mouth, checked web for metallic taste in mouth and this web site came up for side effects of this medication, how strange.Felt better yesterday.T his is my 3rd day on, so wondering what is next. I guess its better than the infection, but I wonder if I should change after reading other comments.

Currently on Biaxin XL on a 14-day regimen for a sinus infection. Experiencing piercing headaches on the top of my head, increased heart rate, diarrhea, insomnia, tongue discoloration, and horrible metallic taste in my mouth. I can't imagine finishing out this 14-day regimen the bad taste in my mouth is enough to gag me. Call into my doctor today for something else as I have never had a problem with side effects in the past on cephalexin or z-pak.
