unbeneficial
Lacking positive effect
Unbeneficial means not helpful or advantageous—failing to produce good results or positive effects.
The word is a straightforward negation of beneficial, used when something lacks expected value: The treatment proved unbeneficial.
It appears less frequently than unhelpful or useless, which cover similar ground.
