If you want after a good long break from medicine, treat him for the common stuff as a precaution e.g. worms etc. You need to only do this once or twice a year for a caged bird that is not exposed to outdoor soils etc.
Also it is usually recommended to follow up on mite treatments, just to make sure you have completely killed any that may have not been active / hatched. Not sure what Iverlux suggests. My meds are usually to be repeated after 6 weeks.
This doesn't include the amoxitex. Only the Ivermectin based medicine.
