Advantage dependent on medication...

[The Cardinal]

Let's say a certain advantage is only available to a character as long as he receives daily doses of a specific drug - how would you price this kind of limitation on an advantage?
Mitigator may only be applied to disadvantages...

I would use Accessibility for that. The price break for "Accessibility: Only while taking daily doses of a specific drug" would be dependent on the rarity and legality of the drug in question.

There's also Trigger, though that's intended for more short-term activations (1 minute, by default). PU8 has "Trigger, Extended", covering activation periods up to 8 hours, at the cost of reducing the value of the Trigger. (Divide by 8, for the 8-hour case.) You could extend that to a 24-hour period by increasing the pattern of the divisor, perhaps to 10 or 12. This means that even a Rare and dangerous Trigger would work out to about -5%, while the other combinations at long duration would work out to -0%.

I might still write it down as Accessibility, but it's a useful comparison for setting the price of that Accessibility. Taking the drug is pretty much entirely under the control of the character, has no particular inconvenience while the drug is active (unlike, say, "Only While Playing Trumpet") or have portability problems, and doesn't take away from on-screen or combat time. So it's a small nuisance at worst (as suggested by the comparison to Trigger, Extended).

I think that the advantage has a variant of gadget limitations. The drug isn't especially breakable (if nothing else, a dose probably has SM -9 or less) and certainly can be replaced. But it can be stolen by stealth or trickery, which is -20%, or if it only works for you, -10%.

Depending on what action and such is required it could be any of:
Trigger, extended (pu 8)
Periodic Recharge(pu 8)
Maintenance
or some sort of accessibility

Not necessarily; the source of the drug could dry up, or withhold it for some reason. The the character is traveling, the supply could run out, or be lost with other luggage during some difficulty, etc.

or you got jumped by your foes and every action is precious, or you don't want to pop pills in the middle of a royal ball.

I'd cook it up as a Power Modifier with Temp Disadvantage: Maintenance (Daily), with the time of the maintenance being how long it takes to come up with "one dose" of the ability, akin to how I cooked up my Chemical power modifier.

In many cases, it should work out to -0%. Humans have a substantial number of advantages (or lack of disadvantages) that will start to go away if you drop key nutrients from your diet, though I suppose it will take longer than a day. If the "drug" is no harder to get than a balanced diet, it most likely isn't enough of a problem to qualify as a limitation.

Mind you it's perfectly reasonable to put a -0% limitations on your character sheet if it is part of the character concept - stuff can be quite a defining feature of an ability or character without necessarily giving (or charging) points.

Pretty much why I wrote "pretty much". But then, any ability can have the occasional plot-driven exception. If a character is being frequently deprived of their abilities on this basis, then the GM would be obliged to raise the value of the Limitation to account for their unusual use of it, or perhaps give them a Disad like Cursed.

A good point to keep in mind. Flavor counts as well as the CP. And as illustrated by Dalillama, the existence of such traits can inspire the details of potentially interesting game events, so they are worth noting.
