How does Pregno Kit work?

  • Mifepristone blocks the hormone progesterone needed to maintain the pregnancy.
  • As progesterone is blocked, the uterine lining begins to shed, the cervix begins to soften and bleeding may occur.
  • After addition of Misoprostol, the uterus begin to contract expelling out the contents
  • Finally leading to the termination of pregnancy.


  •      Medical termination of pregnancy

The recommended regimen for medical abortion

Women with undesired pregnancies ≤63 day’s gestation may be offered the option of the following regimen:

  • Mifepristone 200 mg orally, followed by Misoprostol 800 µg vaginally administered once at any point 1–3 days later.
  • Administering Misoprostol 6–8 hours after mifepristone appears to be equally effective.

Women with pregnancies of ≤49 day’s gestation who prefer the oral route of administration, 

  • Misoprostol may be administered as a 400-µg oral dose 2 days after mifepristone.
  • Misoprostol 800 µg sublingually 2 days after mifepristone is another option for women who prefer to avoid vaginal administration, but they should be counseled about increased side-effects.

Confirmation of Termination

A follow up exam should be scheduled for confirmation of termination after 2 weeks of taking Mifepristone.

What to expect??

  • One may bleed after taking Mifepristone; some women may bleed lightly while other may bleed heavily.
  • Upon taking Misoprostol tablets, cramping, bleeding and clotting may begin as soon as 20 minutes.
  • Within the next 6-8 hours most women suffer miscarriage.
  • Cramping may come in waves with decreasing and increasing intensities.

Adverse Effects

Most of the side effects are due to misoprostol and includes:

  • Heavy bleeding
  • Nausea
  • Headache
  • Vomiting
  • Heavy cramping
  • Diarrhea 


PREGNO KIT is contraindicated in the following populations and situations:

  • In ectopic pregnancy*
  • Intrauterine device (IUD) in place
  • Chronic adrenal failure
  • Concurrent long term corticosteroid therapy
  • Hemorrhagic disorders* or concurrent anticoagulant therapy
  • Inherited porphyria*
  • Allergic to mifepristone, misoprostol or PG analogue.

Warnings and Precaution

  •    Vaginal bleedings may last for 9-16 days. Severe heavy bleeding may require medical attention.
  •       Serious bacterial infection or STDs should be identified.
  •    Vaginal bleeding do not confirm termination so clinical examination or ultra-sonographic scan should be done after 2 weeks of taking pills.
  •      After taking pill if termination didn’t occur then one should not bear child as there are chances of teratogenic effects.

Drug Interactions

  •   Ketoconazole, itraconazole, erythromycin and grapefruit juice may inhibit mifepristone and misoprostol metabolism.
  •    Similarly, rifampicin, dexamethasone, St. John’s Worts, phenytoin, phenobarbital and carbamazepine may induce mifepristone metabolism.

Patient Information

  •      Following termination one can be pregnant.
  •      Contraception can be initiated as soon as termination has been confirmed.
  •     It is unknown whether mifepristone and misoprostol are secreted in the milk or not, so one should consult a doctor if to discard the milk for some days.


Ectopic Pregnancy: Also known as tubal pregnancy, is a complication of pregnancy in which the embryo attaches outside the uterus.

Hemorrhagic Disorders: Spontaneous or near spontaneous bleeding caused by a defect in clotting mechanisms or another abnormality causing a structural flaw in the blood vessels. 

Inherited porphyria: Refers to a group of disorders that result from a buildup of natural chemicals that produce porphyrin in your body.
