My Husband Accidentally Swallowed Laquer Thinner 2 Days Ago. We

my husband accidentally swallowed laquer thinner 2 days ago. We just realized today what was making him sick. He has diarhhea for two days and has been feeling better. He has been working out in the heat today and feels hot flashes and weakness...should I do something or do you think the laquer thinner has worked its way out of his system?
