I weaned off of Lexapro recently of 10mg. Some medications, particularly those for depression or mental illness in general seem to have to be weaned off instead of stopping altogether. I have only found one that can be stopped immediately without being weaned off and that one may just be unique to my metabolism. I began weaning off Lexapro by taking only half a tablet, which was 5mg. After about a week or so, depending on individual symptoms felt, one can successfully completely wean by no longer taking it at all. (This was how I weaned off Lexapro of 10mg). This is not set in stone and may depend on how the individual weaning process is having an effect and worth keeping up and writing down the individual symptoms and side effects to be able to tell your physician. Weaning may be much safer than simply discontinuing to take it immediately and completely, in my opinion. The individual side effects of discontinuing and simply not taking it might prove to be worse.
