Is chicken pox like rashes symptoms of himox overdose?

Unusual: Vesicular (blister-like) eruptions over the body without other lesions would be an extremely rare (if at all possible) allergic reaction to Amoxicillin (the active ingredient in himox). Overdoses of Amoxicillin would be exceptionally rare as well since this drug has few primary toxicities for humans. Chicken pox does not look like many other things.
