Oxytocin
Also known as: Pitocin, Syntocinon
Oxytocin is a potent hormone used to help your pet during labor or to help with milk let-down. * **Professional Monitoring Required:** It should only be used under the direct guidance or administration of a veterinarian who can adequately monitor its effects. * **Risks of Misuse:** Giving oxytocin when a fetus is stuck or the birth canal is not fully open can cause severe complications, including rupture of the uterus and death of the unborn babies. * **Nasal Spray:** If you are prescribed the nasal spray for milk let-down, administer it exactly as directed, usually 5-10 minutes before nursing.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.
What it is used for
- For retained placenta in patients with uterine atony
- For mild to moderate cases of acute post-partum metritis
- For retained placenta in patients with uterine atony
- For mild to moderate cases of acute post-partum metritis
- To control post-extraction cervical and uterine bleeding after internal manipulations
- To promote uterine involution after uterine prolapse manual reduction
- To treat primary uterine inertia
- For adjunctive treatment of metritis
- To induce milk let-down (secondary agalactia)
- For retained placenta
- To reduce incidence of retained placenta
- For mild to moderate cases of acute post-partum metritis
How it is given
Possible side effects
- Uterine cramping and discomfort
- Tetanic uterine contractions (at high doses)
- Uterine rupture
- Fetal compromise or death (due to placental compression)
- Water intoxication (with prolonged high-dose infusions)
- Hypersensitivity reactions (more common with non-synthetic products)
Cautions & contraindications
- Dystocia due to abnormal fetal presentation (unless corrected)
- Closed or unrelaxed cervix
- Known hypersensitivity to oxytocin
- Significant cephalopelvic disproportion
- Obstetrical emergencies where surgical intervention (C-section) is warranted
- Pregnancy (for nasally administered oxytocin)
- > **Critical Warning:** Always evaluate the patient for obstructive dystocia and ensure the cervix is dilated before administration. * **Metabolic Status:** Treat hypoglycemia or hypocalcemia before using oxytocin, as uterine fatigue is often secondary to these metabolic deficits. * **Water Intoxication:** While oxytocin has minimal antidiuretic properties, water intoxication can occur if administered at too rapid a rate or if excessively large volumes of electrolyte-free IV fluids are given concurrently. Signs include depression, coma, and seizures. * **Fetal Monitoring:** Monitor fetal heart rates if possible, as excessive uterine contractions can cause fetal hypoxia.
Drug interactions
- Thiopental: May delay thiopental anesthesia (reported in humans; clinical significance in animals is not firmly established).
- Vasoconstrictors (Sympathomimetics): Concurrent use post-partum may result in severe hypertension. Monitor closely.
