dear patient there is no identified interaction noted with chamomile and clonazepam.... but Possible interactions have been reported with warfarin or cyclosporine. Because warfarin and cyclosporine have a narrow therapeutic index, patients taking either of these medications in more than modest amounts should avoid using chamomile at the same time. Use of the tea and essential oil has resulted in anaphylactic shock, contact dermatitis, and other severe allergic reactions. Persons who are allergic to asters, chrysanthemums, ragweed, and other members of the Asteraceae daisy family should avoid chamomile. i think i helped you if you have any allergy to chamomile or diazepam just check it out..
