Acetaminophen commonly causes hepatic necrosis from acetaminophen overdose resulting from accum of toxic metabolite that froms when glutathione is depleted, risk increased by alcohol or pre-existing liver disease, WHAT IS THE ANTIDOTE FOR ACETaMINOPHEN OVERDOSE?

A

Acetylcysteine = glutatione so toxic metabolite is no longer made

A

Pregabalin (lyrica)

28
Q

What is indicated for neuropathic pain with diabetic neuropathy, postherpetic neuralgia, adjunctive therapy for partial seizures and fibromyalgia (first drug approved originally), sched V, preg cat C, alch/benzo may inc depressant effects and SE include dizzy/sleepy?
