Avelox and warning labels

My grandfather at 86-years-old was prescribed Avelox for bronchitis. The warning on the medication listed by Bayer, the company that makes the drug, states that extreme caution should be used when administering to the elderly. He was also prescribed prednisone, which is a drug that is listed that should NEVER be mixed with Avelox. My grandfather took his own life on April 22, 2008, with no warning signs. He was fine when my grandmother left to go to the store and when she returned, she found him. No other family should have to go through what ours has been through in the past nine days!!!! Do not take AVELOX!!!! We just want to prevent one family from going through what we have been through by warning people about this horrible drug. Doctors need to pay more attention to warning labels and drug interaction- someone needs to stand-up and take some responsibility for medications that harm rather then help!
