HI My father has been suffering from depression mostly emanting out of some kind of fear and anxiety, he was prescribed deanxit and was on same medication for over 4 years, though his depression was under control but it lead to some neural trouble restricting his walking. Later last year after we could not get deanxit, his medicine was changed to nexito plus, but it does not have same impact on his depression ever since, in past few weeks his anxiety, fear thus reaction has increased, alongside no sleep at all at nights. Should we consider increasing the dose or is there any other way to treat it without affecting him further. Appreciate response. Regards Deepak
