Suboxone is buprenorphine with a little naloxone mixed in. Buprenorphine is a partial opioid: it fills the receptor enough to stop withdrawal and craving, with a ceiling that makes an overdose on it alone rare. On a steady dose it does not get you high. It roughly halves the risk of dying from opioids, which is why it is treatment and not a substitute.
A partial agonist sits in the same receptor as heroin or fentanyl but only turns it part way on, and holds it there so nothing else can. That is why withdrawal stops, why craving quiets, and why a full opioid taken on top does much less than expected. The naloxone in the tablet is there to discourage injecting it; taken under the tongue as intended it barely absorbs.
You have to already be in withdrawal, clearly and not just uneasy, or the first dose throws you into a sudden hard one called precipitated withdrawal. After fentanyl the wait is longer and less predictable, and low-dose starts exist for exactly that reason. This is a prescriber conversation, not a forum one.
Take it when you remember. If the next one is close, take the next. It lasts a long time in the body and a single miss rarely undoes anything. Missed several days: tolerance has dropped, and going back to the full dose needs a call first.
Standard opiate panels do not pick up buprenorphine; a specific test does, and a prescription is a prescription. Coming off is slow, with the prescriber, and only if you want to. There is no prize for getting off it, and years on it is treatment working, not treatment failing.
