However, though herbal xanax may seem like a magic pill for a large number of individuals who suffer from anxiety and insomnia, there are some precautions which need to be taken while taking herbal xanax. People who are already prescribed with ketoconazole, better known as Nizoral should stay away from herbal xanax. Herbal xanax may prove incompatible with several other chemical prescriptions, thus it will be better if the individual can inform their doctors beforehand, in case they already are on some precautions. People suffering from liver diseases should consciously try to stay away from taking herbal xanax.
