Hello from JustAnswer.
It is common for topical medicine to fail to eradicate toe nail fungus. The amorolfine is as good as anything on the market, but still may not be able to clear the infection. Oral antifungal medicines are more effective, although it will still take months of treatment. The most effective treatment is to use a combination of topical and oral medicines. The oral antifungal medicines, though, are only available by prescription. If you want the treatment that is most likely to make a difference, then you should discuss oral medicine or combination therapy with your doctor.
If I can provide any clarification, please let me know.
