Other than cards since referees seemingly refuse to give those.
My personal solution would be an imposed three minutes absence if the referee has to stop the game for treatment. You go off the pitch and are restricted for three minutes once the referee restarts the action. Then the fourth official can let you back on once the three minutes are up. I think that would go a long ways towards ending that little abuse.
