What Are The Effects Of Taking Levofloxacin With Levothyroxine?

Thanks so much...my doctor prescribed Levofloxacin and before I took it I read the information sheet. t said Do not take with Sotalol or blood thinners and it also suggested problems with people over 60, I am in my 84th year. Please let me know what the interactions are when taking Levothyroxin withs the drugs I mention, and my age .
