Anybody got a Stimpak?Vault dwellers

Stimpaks are a resource in Fallout Shelter.

A wonder of pre-War science, stimpaks are typically syringes filled with a mixture of healing agents and stimulants, allowing the user to boost their own body's natural regenerative functions.[1] In most cases, it leads to an almost instantaneous regeneration of wounds. The syringe is equipped with a gauge for quickly identifying the state of the contents and can be used either in an intravenous or intramuscular fashion. Although now commonly used for healing bullet holes and stab wounds, stimpaks were employed professionally through Auto-Docs (in conjunction with Med-X and other painkillers) for postoperative care and recovery.[2] John Cassidy speaks of their efficacy, expressing gratitude that millions were produced before the Great War,[3] still abundant several centuries after.

Stimpaks can also be used to treat physical conditions, such as a heart condition, but only temporarily.[4] However, the basic stimpak is designed for use on minor wounds, as the soup of healing medication is ineffective at treating major trauma.[5] A stimpak also does not prevent scarring from excessive third-degree burns or additional extensive scarring as it simply boosts natural regenerative functions.[6][7] Expiration is a concern for those who use stimpaks, but other than giving a weaker boost to healing, they function just as an unexpired stimpak.[8] Chemists with sufficient knowledge can create new stimpaks.[9]


Stimpaks are used to heal 50% of a vault dweller's health. However, they cannot heal any radiation damage done to the dwellers, which is marked with a red bar, until it has been removed with RadAway. They can be given to vault dwellers who are sent to explore the wasteland, who will automatically use them when their health gets too low.

Obtaining stimpaks

There are three basic sources of stimpaks:

Fallout Shelter: The Board Game

In the board game version of Fallout Shelter the stimpak is an item card that can be "exhausted" (tapped) each turn to heal a single dweller. Dwellers can also be healed on spaces noted with a stimpak such as the medbay and the top level elevator space.

Unlike the mobile game, dwellers do not have a health bar (they are either injured or they are not), and if injured cannot be placed anywhere that does not have the stimpak.


The most stimpaks and RadAways a dweller can leave the vault with is 25, but they may acquire and carry more as they explore the wastes.



  1. Fallout Official Survival Guide p.124: "Stimpak: The stimpak is an autoinjector loaded with a variety of healing medications and stimulants. Injecting yourself or another character will increase your natural healing ability and give you an immediate Hit Point boost."
  2. Christine Royce: "Did you know the Stimpak reservoirs ran out within an hour of being in there? I was in there for two weeks, and it kept... repeating the procedure. No Med-X, no stims, just... that sound, feeling the scalpels... cut. Now... we're going to see how you like it when someone else is in control. {Med-X, stims are healing items, and Christine didn't have any, very painful. Now is going to make player pay.}"
  3. John Cassidy: {340}{}{Ahhhh. Boy, am I glad they made millions of these things before the bomb dropped.}
  4. The Lone Wanderer: "Here, take some Stimpaks. That should get him through."
    Madison Li: "Yes, this looks to be enough. He'll need medical attention once we've reached the Citadel, but this will get him there. Thank you. Give me a moment, and we can continue."
    (Madison Li's dialogue)
  5. Vault Dweller's Survival Guide p.5-19: "A stimpak (short for Stimulation Delivery Package) contains many healing chems. A soup of healing medication, if you will. By injecting the Stimpak, you drastically increase your own recuperative functions and restore lost hit points almost instantly."
  6. Joshua Graham can be given stimpaks, but his burn scarring cannot be treated by stimpaks.

  9. The Courier, Myron, the Sole Survivor and Vault Dweller from Vault 76 are all able to create new stimpaks.
