Labtocin Injection

IMPORTANT NOTICE: Oxytocin Injection, USP (synthetic) is indicated for the medical rather than the elective induction of labor. Available data and information are inadequate to define the benefits to risks considerations in the use of the drug product for elective induction. Elective induction of labor is defined as the initiation of labor for convenience in an individual with a term pregnancy who is free of medical indications. Antepartum Oxytocin injection (synthetic) is indicated for the initiation or improvement of uterine contractions, where this is desirable and considered suitable, in order to achieve early vaginal delivery for fetal or maternal reasons. …

• Dosage of oxytocin is determined by uterine response
• The following dosage information is based upon the various regimens and indications in general use
• Induction or Stimulation of Labor Intravenous infusion (drip method) is the only acceptable method of administration for the induction or stimulation of labor
• Accurate control of the rate of infusion flow is essential
• An infusion pump or other such device and frequent monitoring of strength of contractions and fetal heart rate are necessary for the safe administration of oxytocin for the induction or stimulation of labor
• If uterine contractions become too powerful, the infusion can be abruptly stopped, and oxytocic stimulation of the uterine musculature will soon wane
• An intravenous infusion of a non-oxytocin containing solution should be started
• Physiologic electrolyte solutions should be used except under unusual circumstances
• To prepare the usual solution for intravenous infusion–one mL (10 units) is combined aseptically with 1,000 mL of a non-hydrating diluent
• The combined solution, rotated in the infusion bottle to insure thorough mixing, contains 10 mU/mL
• Add the container with dilute oxytocic solution to the system through the use of a constant infusion pump or other such device to control accurately the rate of infusion
• The initial dose should be no more than 1 to 2 mU/min
• The dose may be gradually increased in increments of no more than 1 to 2 mU/min., until a contraction pattern has been established which is similar to normal labor. …

Oxytocin injection (synthetic) is contraindicated in any of the following conditions: • Significant cephalopelvic disproportion; • Unfavorable fetal positions or presentations which are undeliverable without conversion prior to delivery, i.e., transverse lies; • In obstetrical emergencies where the benefit-to-risk ratio for either the fetus or the mother favors surgical intervention; • In cases of fetal distress where delivery is not imminent; • Prolonged use in uterine inertia or severe toxemia …

Oxytocin injection (synthetic) when given for induction or stimulation of labor, must be administered only by the intravenous route and with adequate medical supervision in a hospital.

To report SUSPECTED ADVERSE REACTIONS, contact Fresenius Kabi USA, LLC at 1-800-551-7176 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. The following adverse reactions have been reported in the mother: • Anaphylactic reaction • Postpartum hemorrhage • Cardiac arrhythmia • Fatal afibrinogenemia • Nausea • Vomiting • Premature ventricular contractions • Pelvic hematoma Excessive dosage or hypersensitivity to the drug may result in uterine hypertonicity, spasm, tetanic contraction or rupture of the uterus. The possibility of increased blood loss and afibrinogenemia should be kept in mind when administering the drug. …

Overdosage with oxytocin injection (synthetic) depends essentially on uterine hyperactivity whether or not due to hypersensitivity to this agent. Hyperstimulation with strong (hypertonic) or prolonged (tetanic) contractions, or a resting tone of 15 to 20 mm H 2 O or more between contractions can lead to tumultuous labor, uterine rupture, cervical and vaginal lacerations, postpartum hemorrhage, uteroplacental hypoperfusion and variable deceleration of fetal heart, fetal hypoxia, hypercapnia or death. …

Tome assim que lembrar, a menos que esteja quase na hora da próxima dose. Nesse caso, pule a dose esquecida. Nunca tome duas doses de uma vez para compensar. Confira a bula, pois alguns medicamentos são diferentes.
