Frequently Asked Questions

Fetal tissue and the uterine lining would be loosened by misoprostol. The uterus will contract and, within a few hours, the cervix will dilate. It will cause bleeding and cramping as the tissue moves through the body.

Cramping and bleeding triggers this drug to drain the uterus. Cramping and bleeding typically begin 1-4 hours after misoprostol is taken in most individuals.

For improved effectiveness, vaginal administration of misoprostol is recommended. The prescribed dose of misoprostol is vaginally injected at 800 mcg (4 200-mcg tablets). The results of the study have shown that vaginal administration is more successful than oral misoprostol usage.

During pregnancy, Cytotec can cause the uterus to tear (uterine rupture). As the pregnancy progresses and if you have undergone surgery on the uterus, such as Cesarean delivery, the risk of uterine rupture increases. Extreme bleeding, hysterectomy, and/or maternal or fetal death may result in uterine rupture (tearing).

To allow the tablets to dissolve, lie down for about 30 minutes after you insert the misoprostol tablets. You can push them back in again if you notice the tablets falling out, or call us for instructions on what to do.

The side effects are common, typically lasting just 1 to 4 hours. If any of these side effects make you very uncomfortable, over-the-counter medicines can treat your symptoms. If over-the-counter treatments do not ease the symptoms, call them.

Cytotec is a brand name for the drug Misoprostol. They are the same medication, used to prevent ulcers and manage pregnancy-related conditions.
