How long does Dexamethasone Sodium Phosphate and Lidocaine Hydrochloride stay in your body?

The elimination half-life of dexamethasone sodium phosphate and lidocaine hydrochloride is about 4 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is the plasma (terminal) elimination half-life — the label states the mean terminal half-life is 4 hours. Dexamethasone's anti-inflammatory/biologic effect lasts far longer than its blood levels (commonly cited biologic half-life ~36-54 hours), which is why it is dosed less often than the short plasma half-life implies; the drug is largely cleared from the blood within about a day (roughly 4-5 half-lives, ~1 day), but this clearance window is not the same as a drug-test detection window. Dexamethasone is ~77% protein-bound and metabolized by CYP3A4 (renal excretion is less than 10% of clearance), so strong CYP3A4 inhibitors/inducers can lengthen or shorten exposure. The manufacturer notes the effect of renal or hepatic impairment on its pharmacokinetics has not been formally studied.

It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.
