What happens if you miss a dose of Amisulpride Injection?

Short answer

Amisulpride injection is given by a clinician into a vein, so in most cases there is no missed dose for you to make up at home.

In the US it is approved as Barhemsys for nausea and vomiting after surgery, and the anesthesia or nursing team gives it as a single dose, sometimes with one repeat dose if symptoms continue. That means the usual worry about skipping a dose does not apply the way it does with a daily pill. If your nausea comes back in recovery or at home, tell your care team, because they can add a different anti-nausea medicine rather than repeating this one. If you missed a scheduled appointment where an injection was planned, call the clinic to rebook instead of trying to adjust anything yourself. Outside the US, an injectable form of amisulpride is sometimes used in psychiatric care, and there a missed dose does matter, so contact the prescriber the same day.

What to do about a missed amisulpride dose

1Check the setting:This medicine is given in a hospital or surgery center, so you do not dose yourself between visits.
2Never double up:Do not ask for or accept an extra dose to make up for one you think was skipped.
3Report returning nausea:Tell the nurse or surgical team if vomiting comes back, since a different medicine often works better than a repeat.
4Rebook a missed visit:Call the clinic the same day if you miss an appointment where an injection was scheduled.
5Bring your medicine list:Share every prescription and supplement you take, because some heart rhythm medicines interact with amisulpride.
6Know when to call:Get medical care for fainting, a racing or irregular heartbeat, severe muscle stiffness, or a high fever after a dose.

Common questions

What happens if you miss a dose of Amisulpride Injection?

Amisulpride injection (Barhemsys in the US) is given into a vein by a clinician, usually as a single dose around surgery to prevent or treat nausea and vomiting. Because the anesthesia team gives it, there is no dose to take at home and nothing to catch up on. If nausea returns afterward, tell your care team rather than waiting, since they can decide on a repeat dose or another medicine. If you missed a scheduled infusion appointment, call the clinic to rebook. Outside the US, an injectable form is sometimes used in psychiatric care, and missed doses there can let symptoms return, so contact your prescriber the same day.
