I must be severely allergic to this drug because I think I had every side effect known to man. First the depression came, then disorientation, manic behavior, loss of appetite, insomnia, nightmares, vomiting, becoming a different person, paranoid, crying, confusion, basic emotional freefall. Then I started convulsing, so I rushed myself to the ER. I also broke out all over my chest, and my head was bloated and red too. Of course the ER acted like Biaxin couldn't cause this, so I didn't find out it was Biaxin until I went online and found other sites with other patient reviews. Such a horrible experience and drug. It rendered me incapable of doing my job and school. Never again.
