In no way, it's just a parasitic ability.
People usually get around this by giving the Pokemon a sitrus berry to get it's HP back up.
Here's what I do:
Archeops @ Sitrus Berry
Ability: Defeatist
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Acrobatics
- Aqua Tail
- Head Smash
- Iron Tail
Eat the Sitrus berry to regain health, which loses your item, which powers up Acrobatics.
