For Bronchitis "I have been on Biaxin for 3 days now. I have very loose bowel movements, a horrible taste in my mouth, and I can't sleep. I have been eating Tootsie Roll Pops to combat the bad taste in my mouth. I am going to stop Biaxin immediately and call my doctor first thing in the morning. Up at 2:00 a.m. now, wide awake with diarrhea and a Tootsie Roll Pop!"

For Upper Respiratory Tract Infection "Worked great for infection, but side effects were becoming disturbing after three days - bad taste always, couldn't sleep, too much energy - couldn't sit still, strange mental clarity and deliberate movements, frequent urination. After 3 days, I didn't feel sick anymore, but the side effects were too much."

For Bronchitis "I was prescribed Biaxin for bronchitis. I've taken three pills. I have a horrible taste in my mouth all the time along with severe dry mouth. My stomach is tossing and turning, making the loudest noises I've ever heard a stomach make! I haven't had problems with nausea/vomiting, but the diarrhea from this is horrendous! On the second day of taking this, I got this huge burst of energy and wanted to clean every inch of my house and rearrange each room! (sort of strange as I'm still coughing constantly and having a very hard time breathing) I'm also having trouble sleeping. I'm not sure that I will be taking any more of these."

For Bronchitis "I have been taking Biaxin for 3 days now, and I don't know if my bronchitis is just completely horrible and it's taking longer to work, or if this just isn't for me? The taste it leaves in your mouth after taking it is horrendous for about 12 hours. My stomach has been doing somersaults the entire 3 days so far, and I think I'm going back to the doctor in the morning for another alternative. I can't sleep at all. Hate this stuff."

For Strep Throat "Yesterday I woke up feeling very sick. I had a horrible sore throat, a bad migraine, and I felt like I was going to vomit. I went to the doctor, and he prescribed Biaxin. Ever since I started taking Biaxin, I have been very sleepy during the day and have had restless sleep during the night. It has also left a really bitter taste in my mouth. I have been drinking so much water and going to the bathroom a lot, but it doesn't seem to have made anything better. I will give it a few more days."

For Bronchitis "Prescribed this drug several years ago. Shortly after taking it, I went 5 nights without sleep and was subsequently hospitalized for a manic episode with delusions. It took months to recover from the depression that followed. I was on mood stabilizers for a year and a half post-episode before gaining enough courage to wean off entirely. It has been a few years now that I am clean and clear of all medications. Mentally stable and back to working in emergency medicine. I have since stayed far away from the entire 'myocin' family of antibiotics for fear that I am hypersensitive. Highly recommend staying away from this drug."

For Bronchitis "I only have negative reviews for this drug. Avoid!!!! I started with a milder antibiotic, finished the course, but it relapsed with sinus & chest infection, and so I was put on Biaxin. My sinus took a month to go, but the side effects I could not tolerate were - loss of sleep (no sleep), no appetite, nausea, vomiting, diarrhea, feeling depressed, and emotional outbursts. I'm a very happy person & always around people, but this medicine made me go into a shell. It took a lot of effort from my friends & family to get me back to my normal state of mind."
