Likely because the toxin is that potent. As mentioned, it's Joker toxin + fear toxin + Venom all wrapped up in one.
To help put this in perspective, even the inferior baseline Joker toxin almost instantly took Firestorm out of commission for multiple issues, despite the fact that he received an antidote and proper hospital care immediately after being exposed. On top of that, he was still feeling the toxin's effects after entering the fray again... And mind you, FS has complete molecular control and accelerated healing.
Bruce has neither(that we know of), and was exposed to a far more potent variation of the toxin... So even IF you ignore him recovering in minutes after Harley gave him the tea, he still pushed past the 'super-toxin's' effects for a few issues without fully succumbing. The showing is legit insane any way you slice it.
