Cytotec – Misoprostol uses, dose and side effects


0.2 mg tablets 

1. What Cytotec is and what it is used for

Cytotec is used to heal ulcers in the stomach and for preventive purposes to prevent the appearance of ulcers in the stomach and duodenum in patients with an increased risk of ulcers when treated with drugs for inflammation and pain. Cytotec protects the gastric mucosa by increasing the production of mucus in the stomach and the excretion of bicarbonate in the duodenum. Cytotec also inhibits gastric juice secretion and reduces nocturnal gastric acid secretion.

2. What you need to know before using Cytotec

Do not use Cytotec if you

  • is allergic to misoprostol, other prostaglandins, or any of the other ingredients of this medicine (listed in section 6).
  • is a fertile woman and does not use effective contraception to avoid pregnancy (see section “Pregnancy” for more information).
  • is pregnant or trying to conceive, or does not have a negative pregnancy test, as this medicine may cause miscarriage. Women who have not reached menopause should use adequate contraception before starting treatment with Cytotec.

Warnings and cautions

Talk to your doctor or pharmacist before using Cytotec if you

  • are pregnant or planning to become pregnant (see section “Pregnancy” below). Due to the risk to the fetus, treatment with Cytotec must be stopped immediately.
  • is a fertile woman (see section “Pregnancy” below). Due to the risk to the fetus, you must use an effective contraceptive while taking Cytotec.
  • have a disease that makes you more prone to diarrhea, such as inflammatory bowel diseases such as ulcerative colitis or Crohn’s disease.
  • suffers from angina or narrowing of the blood vessels to the heart or brain, has severe problems with blood circulation ( peripheral vascular disease or if you have high blood pressure ).
  • concomitantly treated with anti-inflammatory and analgesic drugs of the NSAIDtype.
  • is sensitive to dehydration.

Other medicines and Cytotec

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Cytotec may affect the effectiveness of certain other medicines if they are taken at the same time, such as medicines containing ketoconazole (for fungal infections). Concomitant treatment with antacids (anti-heartburn agents) containing magnesium should be avoided as it may worsen misoprostol-induced diarrhea. Concomitant use of anti-inflammatory and analgesic drugs of the NSAID type can in rare cases cause an increase in certain blood levels, as well as fluid accumulation in the body (swelling in the ankles, legs, and/or hands).

Blood pressure-lowering drugs containing propranolol may, after repeated dosing of Cytotec, lead to a moderate increase in the concentration of propranolol in the blood.

Cytotec with food, drink, and alcohol

Cytotec should be taken immediately after a meal.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.


Do not take Cytotec if you are pregnant or planning to become pregnant. Your doctor will inform you about the risks if you become pregnant as Cytotec can cause miscarriages, premature births, and fetal malformations. In pregnancies where the woman has taken misoprostol during the first three months (the first trimester), there has been an approximately three times as large increase in fetal malformations, especially facial paralysis, and malformation in the arms, legs, and head. If you are exposed to Cytotec during pregnancy, talk to your doctor. If you decide not to terminate the pregnancy, you must be closely monitored and repeated ultrasound examinations must be performed, paying special attention to the baby’s legs, arms, and head.

Cytotec must not be used during pregnancy. Women of childbearing potential using Cytotec should use effective contraception. Should you nevertheless become pregnant during treatment with Cytotec, you should stop taking Cytotec and contact your doctor. 

The risk of rupture of the uterus increases with the length of the pregnancy and with previous surgery in the uterus, including a cesarean section. The number of births a woman has undergone also seems to be a risk factor for rupture of the uterus.


Cytotec should not be used by breastfeeding women as misoprostol passes into breast milk and may cause side effects such as diarrhea in breastfeeding babies.

Driving and using machines

Cytotec may cause dizziness. If you feel dizzy or drowsy after taking Cytotec, do not drive or use machines until these symptoms have subsided.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.

This medicine contains less than 1 mmol (23 mg) sodium per tablet, ie it is essentially ‘sodium free’.

3. How to use Cytotec

Always use Cytotec exactly as your doctor has told you. Ask your doctor or pharmacist if you are unsure.

The usual dose for adults is 1 tablet 2-4 times daily. Cytotec should be taken immediately after a meal, to reduce the risk of diarrhea, as well as the last dose at bedtime. Cytotec and medicines for pain/inflammation should be taken at the same time if possible.
