To cure vampirism in The Sims 3, have the vampire buy the anti-vampirism potion at the science lab (the route added by Late Night), or drink a Potent Cure Elixir brewed with the Alchemy skill (added by Supernatural). Both turn the Sim back into an ordinary human. This guide covers each cure step by step, what they cost, which Sims can take them, and what does not work despite what older guides claim.
Which Expansion You Need
Vampires first came to The Sims 3 with the Late Night expansion, and Supernatural expanded them later. The cure you can use depends on what you own:
| Cure | Expansion needed | Where |
|---|---|---|
| Anti-vampirism potion | Late Night | The science lab rabbit hole in town |
| Potent Cure Elixir | Supernatural | Brewed at an alchemy station |
If you have both packs, you can use either. The base game on its own has no vampires, so no cure is needed.
Method 1: Buy the Cure at the Science Lab (Late Night)
The quickest option. Community documentation says the science lab sells an anti-vampirism potion (listed in the game as Vampirism-B-Gone) for §3,000.
- Select your vampire Sim and send them to the town’s science lab (the science facility building on the map).
- Click the building and look for the option to buy the vampire cure. It only appears for vampire Sims.
- Pay the fee. The Sim drinks the potion and returns as a normal human.
Make sure the household has the money first. If funds are short, our guide to enabling cheats covers kaching and motherlode.
Method 2: Brew a Potent Cure Elixir (Supernatural)
The Potent Cure Elixir cures more than vampirism: per community documentation it removes any occult life state, so it also works on werewolves, fairies and witches.
- Buy an Aleister’s Alchemy Station from Buy Mode and have the Sim research alchemy.
- Reach Alchemy level 7. Community documentation lists the Potent Cure Elixir at that level.
- Gather the ingredients. The same documentation lists a wolfsbane flower, glow orbs and a ruby.
- Mix the elixir, then have the vampire drink it, or throw it at them from another Sim.
The Elixir Consignment Store sometimes stocks elixirs and ingredients if you would rather buy than brew. Our skill cheat guide can push Alchemy to 7 immediately, and the Alchemy career guide shows how to turn the skill into income.
Who Can Be Cured
Age is the catch. Per community documentation, vampire babies, toddlers, children and teens cannot take the cure; they have to age up to young adult first. Vampire children born to vampire parents are vampires from birth, so a family of vampires will need to cure each child separately once they grow up.
What Does Not Work
Some older guides, including an earlier version of this one, suggest removing vampirism through Edit Sim in CAS with testing cheats. We could not confirm that Edit in CAS lets you change an existing Sim’s supernatural type, so do not rely on it. The testing cheats mailbox menu does include a Supernatural population control option, but community documentation describes it as controlling the supernatural population of the town, not curing a specific Sim.
If you use mods, NRaas MasterController is widely used to add or remove life states, according to its community documentation. See our mod installation guide before trying it, and back up your save.
After the Cure
Once cured, the Sim loses the vampire thirst need and sunlight sensitivity and gets ordinary human needs back. Vampire powers such as mind reading and hunting go with it. If your Sim ever wants to go back, our vampire guide covers every route, and the werewolf guide covers the other big occult.
