What to expect

Most people tolerate Z-drugs (sleep) well. Here is what is worth knowing going in, so nothing catches you by surprise.

Additive with every other sedative, and the complex sleep-behavior warnings (driving, eating with no memory of it) are on the label for a reason. Worth comparing honestly against the sleep-stack alternatives already tracked here.

Known interactions

Interactions involving Z-drugs (sleep)'s drug class that DoseIQ screens for. Each one cites where it comes from — an FDA label section or the published record — because an interaction warning you can't trace is just noise.

Worth knowing Multiple sedating agents — additive drowsiness

Trazodone, gabapentin, micronized progesterone — each mild alone, cumulative together.

What to do: Time them all at night, and judge morning grogginess honestly.
