Amputation Stops Spread
Lars: You cut [Dimo's] arm off!
Oggie: Um... Dis vos de right von, yah?
Lars: It's melting!
Oggie: Yop. Dot vas it.Sometimes when sucking out the poison isn't enough, someone simply cuts off the limb in question, above the problem. Naturally, this is not recommended in real life as blood flows faster than an arm or leg can be cut off, amputation is dangerous enough as is, and amputation to prevent infections are an old and largely outdated medical practice. Mostly used in the case of Zombie Apocalypse-style infections, where the infection will be fatal, and this is the only option to save their life. Subtrope of Life or Limb Decision.

- In the story "To kill a werewolf" published in Marvel's Vampire Tales #1, a werewolf bites the protagonist's arm, which quickly transforms into a canine paw. The doctors amputate it before it can spread to the rest of his body. It seems to have worked, but many years later he transforms into a werewolf completely anyway.

- Subverted in The Blob (1988).

- An intern isn't as lucky. When he gets it on him, they apply iodine (which the Clone is repulsed by) to his arm.

Harry chops his arm off anyway, but it's too late by this point.
- Subverted in a cruelly ironic way later in the novel. Chuck Danton has the misfortune of getting absorbed headfirst. His companions pull him free, and his head comes off, halting the absorption at the neck and leaving the rest of his body intact, but for obvious reasons he still dies. But, hey, it did stop the spread of the Clone flesh! There's a body to have a funeral with, at least.

- Attempted in Agents of S.H.I.E.L.D.'s second season premier when an alien artifact causes an agent's hand, then arm, to slowly start turning to stone.

- General Randall in [PROTOTYPE] hacked off his own arm with a cleaver after being bitten by Elizabeth Greene, fearing that she might have infected him with the Redlight Virus.
- In Virtue's Last Reward, Sigma does this during Quark's ending, using a giant door as a crude cleaver to cut off his hand and save him from a fatal injection. Justified because he has a bracelet attached to his wrist that has already given him an anesthetic and will give him the poison within 9 minutes, and because Sigma's ending reveals that his arms are cybernetic, so they are expendable.
