I have been using Nizoral for years to control flaking/dandruff and have recently found it may have interactions with my Amiodarone and would appreciate it if you could explain this further to me. I have tried every dandruff shampoo on the market, Head Shoulders, Selsun Blue and vinegar rinses to no avail. If you could please explain what could be a possible problem with the topical and oral meds together. I know there is an interaction between the oral medications and should not be taken together but I need my shampoo, is there a serious medical reason why I can not continue using my shampoo.
