Many switch without a delay/waiting period, between biologics. Why? Because detectable levels of remicade were found in patients 12-weeks (3-months) after their last infusion and discontinuation (and it's perfectly reasonable to expect other biologics to stay as long). It takes a long, long time to clearance all of a biologic from your body, 6-months or more. Can you wait a week or two between them?, Sure but it isn't going to really do/accomplish much. Over time, the levels/concentration of the old biologic drop and become less and less of an issue.
