Prevent

Prevent is a miscellaneous item in Fallout 4.

Background
Prevent was developed by the Med-Tek research facility before the Great War and cures an unknown illness. Testing on subjects came with a multitude of symptoms (including alopecia, the development of cysts in adults, and priapism in males) and the pharmaceutical was never finalized before the war struck.

Characteristics
Prevent must be acquired by Robert MacCready and the Sole Survivor to save MacCready's son. It is a quest item, meaning it cannot be dropped and does not take up any weight in one's inventory despite having a weight of 1.
