Oxytocin
別名: 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.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。

給藥方式
可能的副作用
- 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)
注意事項與禁忌
- 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.
