Necrosis by drug injection?

(1) is it reversible(recoverable)? if so, to what extent?

(2)why does the FDA approve licensing of drugs that have post-market incidents of necrosis? is it simply leveraging between the side effects and efficacy of the drug?ex. muscle cell necrosis by intramuscular injection from injection inflammatory reactions.
