Pickups |
Hearts | Coins | Bombs | Keys | Batteries | Pills | Cards/Runes | Chests | Sacks |
Pills are pickups that can provide useful or inhibiting effects. They take up the same slot as cards and runes.
At the start of each run, an effect is randomly assigned to each color of pill. The pill effect for each color will remain constant throughout the run. (However, it is possible for PHD, Virgo, False PHD, or Lucky Foot to reassign some of the effects, such that 2 different colored pills will have the same effect.) Pills start the game unidentified (unless the player is holding PHD or False PHD); their effect is shown as "???" when picked up. Upon using a particular pill for the first time, its effect will be revealed and all subsequent pills with the same color will have their effect shown as well. The set of pill effects for any given run is usually known as the pill pool.
- The pill pool for each run has increased from 9 to 13.

This effect can be negated by picking up Black Candle, but will not prevent future uses of the ??? pill from giving the Curse of the Maze effect. As the pill's name is "???", the same as what unidentified pills are referred to, it is easy to accidentally use it more than once per run. It is recommended to memorize its color upon first using it. Unlocked by: Complete Have a Heart (challenge #25). |
No difference. |
32 | One makes you larger | N | 1 | Increases Isaac's size and decreases the pitch of his voice. This effect does not increase the size of Isaac's hitbox, but increases the size of The Forgotten's bone club. These pills contribute to the Stompy transformation. | Size increases by two steps. |
33 | One makes you small | N | 1 | Decreases Isaac's size and increases the pitch of his voice. This effect decreases the size of Isaac's hitbox; a small enough hitbox allows Isaac to walk "under" certain projectiles to avoid them. | Size decreases by two steps. |

44 | Horf! | N | 0 | Isaac shoots an explosive tear with the Ipecac effect that always deals 200 damage. Unlocked by: Participate in 31 Daily Challenges (they don't have to be consecutive; it will still count if Isaac dies in the first room). |
Isaac shoots a cluster of 6 Horf! tears with 150-400 damage per tear, resulting in an average of 1650 damage if all tears or their explosions hit. |
45 | Feels like I'm walking on sunshine! | + | 1 | Temporarily makes Isaac invincible, similar to Unicorn Stump. Unlocked by: Collect every entry in the Bestiary (bugged v190 - Mobs that don't exist in the bestiary are being counted. This allows Sin Collector to be unlocked without a complete bestiary). |
The effect is upgraded to The Gamekid's. |
46 | Vurp! | + | 2 | Spawns the last pill used. Will spawn itself if no other pills were taken beforehand, or if Vurp! was the last pill used. Unlocked by: Obtain 50 items in a run (duplicate passive items/familiars count towards the total, e.g., multiple Breakfast). |

Pill Classes[]
Repentance introduces the mechanic of pill classes. Internally, pills are given a class from 0 to 3 and a polarity that reflects their influence:
Pills in class 0 have little to no impact on a run overall, while pills in higher classes are correspondingly more influential, class 3 pills having effects as significant as permanent stat changes. Classes that end with + or - denote a positive or negative effect, otherwise considered neutral.
This mechanic is used to balance the pill pool and avoid having too many negative or positive pills. Polarity is used by certain items to determine which pills to convert.
Gold Pills[]
Repentance introduces Gold Pills (or Golden Pills). Using them will give a random pill effect. Gold pills only have a chance to be "used up" upon using them, which means that you can often use them many times before they finally disappear.
- Unlocked by: Defeat Mega Satan as Tainted Cain.
- The possible effects are all effects that aren't in the run's pill pool, which means if you see an effect from a normal pill, you will never see it from a golden pill.
- Items such as PHD or Lucky Foot which alter pill effects also work on the effects of this pill, allowing many beneficial effects to be stacked with little risk. Effects altered by these items may overlap with the effects in the run's pill pool; for example, a run might have Tears Up in the pill pool and Tears Down outside of the pill pool, which will be turned into Tears Up due to the effects of the item.
- Gold Pills have an ID of 5.70.14.
- A Gold Pill can also be a Horse Pill. Golden Horse Pills use the Horse Pill effect on every use.
- Golden horse pills are most likely the rarest pickup in the game with a 0.06% chance of spawning instead of a normal pill.
- If a Golden Pill uses the 'Vurp' effect, and no other pill was used prior, another golden pill will drop.
Horse Pills[]
Repentance introduces Horse Pills. These are larger versions of the standard pills with a more powerful effect, but only appear very rarely. Unique sound effects can be heard when they are used, and the narrator's normal spoken voice lines are instead shouted using a different voice.
- Unlocked by: Defeat Mega Satan as Tainted Eve.
- All items that work with pills work identically with horse pills.
- A horse pill with a given effect has the same color as the normal pill does.
- Horse pills have an ID of the normal ID + 2048 (i.e. 1 << 11). For example, a white-blue pill has an ID of 2, so the horse pill version would have an ID of 5.70.2050.
- It is also possible to have a golden horse pill. (It has an ID of 5.70.2062.)
Probabilities[]
Pills that spawn with a sub-type of 0 (i.e. a random pill) will have the following probabilities:
- Random normal pill - 97.86%
- Specific normal pill - 7.53%
- Gold pill - 0.7%
- Random horse pill - 1.43%
- Specific horse pill - 0.11%
- Gold horse pill - 0.01%
Notes[]
- Among the attribute-modifying pill effects, only five of the seven visible attributes are covered: health, range, tears, speed, and luck. Both shot speed and damage can't be altered by pills.
- Shot speed can now be altered with pills. Damage can now also be altered with pills with False PHD.
- If a "Health up" pill is used while Isaac has 11 empty red hearts and one non-red heart, the non-red heart will be replaced with an empty container, killing Isaac.
- Having Midas' Touch, Meconium, or Hallowed Ground and using a "Re-Lax" pill has a chance to spawn Golden Poop, Black Poop, or White Poop, respectively.
- A similar synergy is observed when using the A Card Against Humanity item in conjunction with these other items as well.
- If the item PHD is picked up and then lost in any way, such as rerolling by the D4 or a Dice Room, or dropping it as Tainted Isaac, pills will remain fully identified for the rest of the run, but negative pills will not be converted.
- Pill effects have a chance to be narrated upon use, as do cards and runes.
- Currently, the "Retro Vision" pill effect can crash the game on some machines, resulting in restarting the current floor when the game is continued.
- The "Addicted!" pill will have no effect if Isaac has The Wafer.
- Despite this, if Isaac takes both the "Addicted!" pill with "Percs!" in the same room, a full heart of damage will be taken from all sources.
- Using an "Infested!" pill on Red Poop will spawn blue spiders and the red poop will regenerate.
- If a Tiny or Large Champion monster drops a "One Makes You Small"/"Larger" pill and either pill is not in the current pill pool, an existing pill will be overwritten. If the chosen pill was already identified, the new pill will also be.
- "R U A Wizard" does not affect Lilith's Incubus.
- Isaac's hitbox can be reduced to 30% of original, which is achieved after 6 One Makes You Small pills. Further pills will only make him visually smaller, with no additional benefit.
- Using a "Gulp!" pill while holding two trinkets (with Belly Button or Mom's Purse) will cause both trinkets to be absorbed.
- Magdalene's starting pill will override one of the pills in the current run's pill set if it doesn't exist in it (Speed Up for Afterbirth+, or Full Health in Repentance). The pill that is converted is dependent on the run's seed.
- This only applies if the run is started as Magdalene or if Magdalene is chosen as a Co-op partner, not if Isaac turns into Magdalene using Clicker.
- All golden pills in the run have a shared sequence of effects they activate, so reversing the effects of one golden pill through Glowing Hourglass and consuming another golden pill will activate the same effects.
- If a Vurp! effect is activated by a golden pill, it will spawn the last non-golden pill taken by Isaac, or a golden pill if no non-golden pills have been taken by Isaac in the run.
- If a Marked Skull is destroyed while Isaac is holding Little Baggy, it will spawn a Telepill instead of 0 - The Fool. If Telepills doesn't exist in the current run's pill set, one of the pills in the run's set will be turned into Telepills. The pill that is converted is dependent on the run's seed.
- All other pills with the same color as the Telepill spawned will also be converted into Telepills for the rest of the run, even if they're currently being held by Isaac. This can also override Magdalene's starting Full Health pill.
- While transformed into The Lost by a White Fireplace, Health Down pills turn into Health Up pills, regardless of Isaac's number of red heart containers.
- Damage from "Bad Trip" pills can be negated if Isaac consumes the pill during invincibility frames.
- It is possible to use "Paralysis" in one room and its effect happening in the next room only if you time it frame-perfectly.
Strategy[]
- There are 24 good effects, 14 neutral (sometimes good/sometimes bad) effects, and 12 negative effects. This means that taking mystery pills is usually beneficial. However, you should consider not taking one if an effect like Hematemesis or Tears Down would ruin your run.
- Use of unidentified pills is recommended for outside of combat as Hematemesis, R U a Wizard?, Paralysis, Addicted!, X-Lax, and I'm Excited!!! can be detrimental mid-fight. However, I'm Drowsy..., Something's wrong..., Lemon Party, Bad Gas, and Pheromones are useless outside of combat.
- Percs! can be used in the Sacrifice Room to reduce the damage Isaac takes, potentially allowing him to do more sacrifices. However, if Isaac is teleported to the Devil/Angel room, he loses the effect.
- The invincibility effect from Power Pill and Feels like I'm walking on sunshine! can be utilized to get into Curse Rooms, play Blood Donation Machines and Confessionals, or use Devil Beggars and Hell Games without taking any damage.
- Percs! can be used to reduce damage from these from chapter 4 onward.
- Endless Nameless can be used to effectively generate infinite golden pills, as the trinket's ability to respawn collectibles applies with every use.
- Taking only golden pills in a run can allow for infinite golden pill generation by repeatedly activating the Vurp! effect.
Unlockable Achievements[]
- Huge Growth - Increase in size 5 times in a single run via Magic Mushroom, "One makes you larger" pills, XI - Strength, etc..
Trivia[]

- Balls of Steel is a reference to Duke Nukem; it is one of Duke's more famous quotes.
- Explosive Diarrhea is extremely loud and forceful diarrhea. In the original game, the message that displayed when the pill was activated was "Oh No!".
