Fungal nail infections can only be adequately treated with oral tablets which have to be taken for a few weeks for them to have a maximum effect. In many cases they would have to be used for 6 to 12 weeks. In terms of effects on your liver and kidney, most persons use the medications with no effects, so the risk is there but is not experienced by the majority of persons on the medication. I hope this helps </s>
