Favorable safety profile

No pharmacologically active substances

Dilapan-S® works with the body, without medications.7-9

No uterine tachysystole

In 2 large studies representing a total of 640 women (including VBAC patients) using Dilapan-S®, there were no cases of uterine tachysystole related to Dilapan-S® use during cervical ripening.3,8

Non-serious adverse events

Of 444 women treated with Dilapan-S® during induction of labor2:

  • <1% reported cramping or pain
  • 2.7% experienced bleeding during Dilapan-S® insertion or removal
  • No maternal infections (including chorioamnionitis, urinary tract infections, endometritis, and wound infections) were attributed to use of Dilapan-S® by the investigating physicians
  • No serious adverse neonatal outcomes were attributed to use of Dilapan-S®

Instruct patients to: Report any excessive bleeding, pain, or temperature elevation, and to avoid bathing, douching, and intercourse.

A proven, versatile cervical ripening agent for a broad variety of patients

In a clinical study of 444 women, the average increase in Bishop score with Dilapan-S® was +3.6.2

Patient Satisfaction

Significantly higher patient satisfaction with Dilapan-S®1

In a head-to-head trial with 419 pregnant women, patients were more satisfied with Dilapan-S® compared with Foley balloon in 3 domains (P<0.05).

Patients who received Dilapan-S® reported1:

  • Better sleep (P=0.01)
  • More relaxing time (P=0.001)
  • Ability to perform daily activities (P=0.001)

93% of patients described the comfort of insertion as fully acceptable3

ALMOST 80% of patients were able to sleep during cervical ripening3

Patients should return to the physician for removal of Dilapan-S® at the indicated time and should be instructed not to attempt self-removal under any circumstances.
