For stimpak types that appear in the Fallout series, see Stimpak.

For fast, effective healing of both overall health and every injured body part, nothing beats a Stimpak.

Stimpaks, or stimulation delivery package, are a consumable item in Fallout 4 used for healing.


This item consists of a syringe for containing and delivering the medication and a gauge for measuring the status of the stimpak's contents. When injected, it provides fast healing of injuries.

  • Each rank of the Medic perk enhances the efficiency of both stimpaks and RadAway. Rank 1 improves it to 40%, rank 2 to 60%, rank 3 to 80% and rank 4 to 100%. Rank 4 also increases the speed of stimpak healing. The Medicine bobblehead further increases the stimpaks' efficiency by 10%.
  • Unlike previous installments, Fallout 4 's stimpaks deliver over a small amount of time rather than immediately, much like how stimpaks work in hardcore mode for Fallout: New Vegas.
  • Unlike Fallout 3 and Fallout: New Vegas, an animation is played when taking any stimpak. This animation is shown only once regardless of the amount of stimpaks used, and is not shown at all while wearing power armor.
  • Stimpaks in Survival mode have a dehydrating effect.
