Natural substances produced by the body, prostaglandins have various functions, including the stimulation of uterine contractions (organ of pregnancy and childbirth).

Prostaglandin E2Pfizer 10mg/ml is a medication that your doctor will administer to you via intravenous infusion (injection of the solution into a vein), which stimulates the uterine muscle, causing contractions similar to those observed in the uterus during childbirth.

Prostaglandin E2Pfizer 10mg/ml is used for delayed abortion (expulsion of a dead fetus from the uterus) and for hydatidiform mole (abnormal growth of the placenta).

No use Prostaglandin E2Pfizer 10mg/ml:

• If you are allergic to dinoprostone or any of the other components of this medication (listed in section 6).
• If you have any of the following situations, in which labor-inducing or accelerating medications should not be used, or in which prolonged uterine contractions are not appropriate:

• If you have had a previous cesarean section or major uterine surgery.
• If you have been told that you are at risk of obstructed labor.

• If you have uncontrolled heart, lung, liver, or kidney disease at the present time.
• If you have a uterine, ovarian, or fallopian tube infection (pelvic inflammatory disease) and are not receiving treatment for it, or if you have had this type of infection in the past.
• If you are being given a medication called oxytocin or other medications that also stimulate uterine contractions (see section “Use of Prostaglandin E2 Pfizer 10 mg/ml concentrated solution for infusion with other medications”).
• If you are at risk of developing intravascular coagulation and/or fibrinolysis (coagulation problems).

Use of Prostaglandin E2Pfizer 10mg/ml concentrated solution for infusion with other medications

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

Prostaglandin E2 Pfizer 10 mg/ml concentrated solution for infusion may increase the effect of a medication called oxytocin that stimulates uterine contractions, so these medications should not be used at the same time. If your doctor considers it necessary to administer oxytocin, they should leave a 6-hour interval between the administration of both medications and closely monitor your uterine activity.

Pregnancy and breastfeeding

In the case of abortion, it is essential that this be complete, so your doctor can establish the appropriate treatment for the complete expulsion of the fetus.

It is expected that the small amount of alcohol in this medication will have no adverse effects.

The treatment will be administered by professionals with expertise in managing this medication and will only be carried out in hospital centers or clinics with access to intensive care and emergency surgery.

However, if you believe you have received more Prostaglandin E2 Pfizer 10 mg/ml than you should, inform your doctor immediately.

Excessive administration of this medication may manifest as an increase in uterine activity (stronger, more frequent, and painful contractions). However, this is a transient condition and usually ends with a change in the woman's position and administration of oxygen. Beta-adrenergic medications (which have a similar action to adrenaline) may also be administered.
If uterine activity is very intense, your doctor may reduce your dose or stop administering the medication. If uterine activity is excessively intense, your doctor will take the necessary measures.
In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicological Information Service at 91 562 04 20, indicating the medication and the amount ingested.

This information is intended solely for healthcare professionals:

Care should be taken in handling this product to avoid contact with the skin. Hands should be thoroughly washed with soap and water after administration of the preparation.

The concentrated solution for infusion will be administered previously diluted exclusively by intravenous route.

This medication should be diluted before use using the appropriate diluents. The preparation of the diluted solution from Prostaglandin E2Pfizer 10 mg/ml concentrated solution for infusion, will be performed by extracting 0.5 ml from the ampoule using an aseptic technique. The amount extracted will be added to 1,000 ml of a normal saline sterile solution or 5% dextrose, so that the final concentration is 5 micrograms/ml. It should be shaken to ensure uniformity of the solution.

Before administration, a visual examination will be performed to check for the presence of particles or discoloration, whenever the solution and container allow.

To administer this medication by intravenous infusion, a dosing device (60 drops/ml) or a constant flow infusion pump can be used.

A dosing device that releases 60drops/ml (pediatric administration equipment) or a constant flow infusion pump will be used. The initial infusion rate will be 2.5micrograms/minute (30drops/minute), which will be maintained for at least 30 minutes. If the uterine response is satisfactory, this rate will be maintained; if not, it will be increased to 5micrograms/minute (60drops/minute). If a satisfactory uterine activity is not achieved after at least 4 hours at this infusion rate, it may be increased to 10micrograms/minute (120drops/minute) provided that the side effects allow it, and will be maintained in this way until the abortion occurs or until it is considered that the treatment has failed.

If significant side effects appear, the infusion rate should be reduced to 50%, or the treatment should be interrupted.

Administration of the medication continuously for more than two days is not recommended.

If a constant flow infusion pump is used, it may be necessary to use a different solution concentration (e.g. 15micrograms/ml), depending on the type of pump, although the infusion rate of the doses (micrograms/minute) will remain as detailed above.

Appearance of uterine hypertension requires interruption of treatment until normal state is achieved again. Then, administration of treatment will be re-evaluated, and if necessary, perfusion will be initiated but at lower velocities, 50% of the last dose used.

If no response is observed in the first 12-14 hours since the start of treatment, the treatment will be suspended.
