Medically reviewed by Drugs.com. Last updated on Aug 9, 2023.

Usual Adult Dose for Labor Induction

VAGINAL INSERT:

• Single dose: 10 mg intravaginally (designed to be released at approximately 0.3 mg/hour)
• Duration of therapy: Up to a 12-hour period

Comments:

• Remove the vaginal insert 12 hours after insertion with the onset of active labor, prior to an amniotomy, occurrence of uterine tachysystole, uterine hypersystole, hypertonicity, or fetal distress.
• Should be removed at least 30 minutes prior to administering an oxytocic agent.
• Care should be taken to ensure the vaginal insert remains in place if the patient is ambulatory.

CERVICAL GEL:

• Initial dose: Syringe applicator with 0.5 mg in 3 mL to be applied endocervical
• Repeat dose: If there is no cervical/uterine response, a recommended repeat dose of 0.5 mg with a dosing interval of 6 hours may be given.
• The need for additional dosing and the interval should be determined by the attending physician based on the course of clinical events.
• Maximum recommended cumulative dose for a 24-hour period: 1.5 mg

Comments:

• Vaginal examination will reveal the degree of effacement which will regulate the size of the shielded endocervical catheter to be used. The 20 mm endocervical catheter should be used if no effacement is present, and the 10 mm catheter should be used if the cervix is 50% effaced.
• This product should be handled carefully to prevent contact with skin. Hands should be washed thoroughly with soap and water after administration.
• The manufacturer product information should be consulted for instructions relating to product preparation and proper insertion.
• Following administration the patient should remain in the supine position for at least 15 to 30 minutes to minimize leakage from the cervical canal.
• If the desired response is obtained, the recommended interval before giving IV oxytocin is 6 to 12 hours.
