This was a favorite tactic of Poison Ivy in her early appearances in the Batman comics. Gradually she gained the ability to generate poisons in her body, negating the need for the drugged lipstick.
In her earliest appearances in Batman: The Animated Series, Poison Ivy is shown applying drugged lipstick to create her toxic kisses, something she uses against Harvey Dent and Batman in her first episode. Later episodes make the poisonous kisses natural, and show her creating doctored lipstick for Harley Quinn to use in order to cause the same effect. Whether this is a retcon or an implication that Ivy's powers evolved over time (a reasonable hypothesis, given other changes, like her skin color) is unknown, but as she does possess an antidote to her own poisons and was later shown giving Harley Quinn an injection for the same, it can be assumed that even in her earliest appearances she'd already treated herself to prevent from being poisoned.

In La Reine Margot the resident Master Poisoner gives Henri of Navarre's lover some poisoned lipstick. An unusual example in that this does in fact kill the woman wearing it; she was an Unwitting Pawn and was deemed expendable as long as she inadvertently killed her target. She failed, the poison was too fast-acting and it killed her before she got a chance to use it on him.

In the Torchwood episode "Kiss Kiss, Bang Bang", Jack tells Gwen not to let Captain John Hart kiss her; when he does, it turns out that it's because he wears paralyzing lipstick. Oddly enough, Jack himself seems to be immune, as Jack and John repeatedly engage in Slap-Slap-Kiss and Kiss-Kiss-Slap throughout the episode. (Though John did disappear right before he kissed Gwen, so he could have been putting it on then and could have taken it off afterward when he kissed Jack goodbye.)
In the Firefly episode "Our Mrs. Reynolds", Saffron wears lipstick with some kind of soporific property, which she uses to knock out Mal (and, indirectly, Inara).

It turns out that cynoxate, an ingredient in Stephanie's lip gloss, is the kryptonite to Jim's Applied Phlebotinum, the trilsettum coronis. She claims to have gotten rid of it, but apparently still has it lying around, because in a later episode, the evil shape-shifter Victoria turns into Stephanie and steals the lip gloss, neutralizing Jim's powers when she kisses him.
