Misoprostol tablets RX only (2023)





Misoprostol should not be used to reduce the risk of NSAID-induced ulcers in women of childbearing age unless the patient is at high risk for NSAID-related ulcer complications or is at high risk of developing an ulcer. In such patients, misoprostol can be prescribed as the patient

  • had a negative serum pregnancy test within 2 weeks prior to starting therapy.
  • is able to adhere to effective contraceptive measures.
  • she received both oral and written warnings about the dangers of misoprostol, the risk of possible contraceptive failure, and the danger to other women of childbearing age if the drug is accidentally taken.
  • she will not start misoprostol until the second or third day of her next normal period.

Misoprostol oral tablets contain 100 mcg or 200 mcg of misoprostol, a synthetic prostaglandin E1analogue.

Misoprostol contains approximately equal amounts of the two diastereomers shown below with their enantiomers marked (±):

Misoprostol tablets RX only (1)

Misoprostol is a viscous, water-soluble liquid.

The inactive ingredients of the tablets are hydrogenated vegetable oil, hypromellose, microcrystalline cellulose, and sodium starch glycolate.


Misoprostol is extensively absorbed and undergoes rapid deesterification to its free acid, which is responsible for its clinical activity and, unlike the parent compound, is detectable in plasma. The alpha side chain undergoes beta oxidation and the beta side chain undergoes omega oxidation followed by ketone reduction to yield prostaglandin F analogs.

In normal volunteers, misoprostol is rapidly absorbed after oral administration with Tmaxof misoprostol acid of 12 ± 3 minutes and a terminal half-life of 20-40 minutes.

There is wide variability in plasma levels of misoprostol acid between and within studies, but mean values ​​after individual doses show a linear relationship with dose over the range of 200-400 mcg. No accumulation of misoprostol acid was observed in multiple dose studies; plasma steady state was reached within two days.

Peak plasma concentrations of misoprostol acid are reduced when the dose is taken with food, and the total availability of misoprostol acid is reduced by concomitant administration of antacids. However, clinical studies have been conducted with concomitant use of antacids, so this effect does not appear to be clinically important.

After oral administration of radiolabeled misoprostol, approximately 80% of the detected radioactivity is excreted in the urine. Pharmacokinetic studies in patients with varying degrees of renal impairment showed an approximate doubling of T1/2, Cmax, and AUC compared to normal values, but there is no clear correlation between the degree of damage and AUC. In subjects over 64 years of age, the AUC for misoprostol acid is increased. Routine dose adjustment is not recommended in elderly patients or patients with renal impairment, but dose reduction may be necessary if they cannot tolerate the usual dose.

Interaction studies between misoprostol and various non-steroidal anti-inflammatory drugs showed no effect on the kinetics of ibuprofen or diclofenac and a 20% decrease in aspirin AUC, which is not considered clinically significant.

Pharmacokinetic studies also showed a lack of drug interaction with antipyrine and propranolol when these drugs were co-administered with misoprostol. Misoprostol administered for 1 week had no effect on the steady-state pharmacokinetics of diazepam when the two drugs were administered 2 hours apart.

The binding of misoprostol acid to serum proteins is less than 90% and is not concentration dependent in the therapeutic range.

After a single oral dose of misoprostol in a nursing mother, misoprostol acid was excreted in breast milk. The maximum concentration of misoprostol acid in expressed breast milk was reached within 1 hour after administration and was 7.6 pg/ml (CV 37%) and 20.9 pg/ml (CV 62%) after a single administration of 200 mcg and 600 mcg misoprostol respectively. Misoprostol acid concentrations in breast milk decreased to < 1 pg/ml 5 hours after dosing.


Misoprostol has both antisecretory (inhibition of gastric acid secretion) and (in animals) mucosal protective properties. NSAIDs inhibit the synthesis of prostaglandins and a lack of prostaglandins in the gastric mucosa may lead to decreased secretion of bicarbonate and mucus and may contribute to mucosal damage caused by these agents. Misoprostol may increase bicarbonate and mucus production, but has been shown to have an antisecretory effect in humans at doses of 200 mcg and above. Therefore, it is not possible to say whether the ability of misoprostol to reduce the risk of peptic ulcer disease is due to its antisecretory effect, its protective effect on the mucosa, or both.

In vitrostudies in canine parietal cells using tritium misoprostol acid as a ligand led to the identification and characterization of specific prostaglandin receptors. Binding to the receptor is saturable, reversible and stereospecific. The sites have a high affinity for misoprostol, its acidic metabolite and other E-type prostaglandins, but not for prostaglandins F or I and other unrelated compounds, such as histamine or cimetidine. The affinity of the misoprostol receptor site correlates well with an indirect index of antisecretory activity. It is likely that these specific receptors allow the local action of misoprostol taken with food, despite the lower serum concentrations achieved.

Misoprostol causes a moderate decrease in pepsin concentration during basal conditions, but not during histamine stimulation. It has no significant effect on fasting or postprandial gastrin or intrinsic factor secretion.

Effects on gastric acid secretion

Misoprostol, in the range of 50-200 mcg, inhibits basal and nocturnal gastric acid secretion and acid secretion in response to various stimuli, including meals, histamine, pentagastrin, and coffee. The effect is visible 30 minutes after oral administration and lasts for at least 3 hours. In general, the effects of 50 mcg were modest and short-lived, and only the 200 mcg dose had significant effects on nocturnal secretion or on histamine and meal-stimulated secretion.

Effects on the uterus

Misoprostol has been shown to cause uterine contractions that can jeopardize pregnancy. (See boxWARNINGS.)

Other pharmacological effects

Misoprostol has no clinically significant effects on serum levels of prolactin, gonadotropin, thyroid stimulating hormone, growth hormone, thyroxine, cortisol, gastrointestinal hormones (somatostatin, gastrin, vasoactive intestinal polypeptide and motilin), creatinine or uric acid. Gastric emptying, immune function, platelet aggregation, lung function or cardiovascular system are not altered by the recommended doses of misoprostol.

clinical studies

A series of small short-term (approximately 1 week) placebo-controlled studies in healthy human volunteers evaluated the ability of doses of misoprostol to reduce the risk of NSAID-induced mucosal damage. Studies of 200 mcg q.i.d. misoprostol with tolmetin and naproxen, and 100 and 200 mcg q.i.d. with ibuprofen all showed a reduction in the number of significant endoscopic injuries from approximately 70-75% on placebo to 10-30% on misoprostol. Doses of 25-200 mcg q.i.d. reduced mucosal damage and bleeding caused by aspirin.

Reducing the risk of stomach ulcers caused by non-steroidal anti-inflammatory drugs (NSAIDs)

Two 12-week, randomized, double-blind studies in patients with osteoarthritis who had gastrointestinal symptoms but no ulcers on endoscopy while taking NSAIDs compared the ability of misoprostol 200 mcg, misoprostol 100 mcg, and placebo to reduce the risk of gastric ulcer ( GU formation. Patients were approximately evenly distributed between ibuprofen, piroxicam and naproxen and continued on this treatment for 12 weeks. The dose of 200 mcg produced a significant, statistically significant reduction in gastric ulcers in both studies. The lower dose was slightly less effective, with a significant result in only one study.

In these studies, there were no significant differences between misoprostol and placebo in the relief of daytime or nighttime abdominal pain. Misoprostol has not been shown to reduce the risk of duodenal ulcers, but relatively few duodenal abnormalities have been observed.

In another clinical trial, 239 patients received aspirin 650-1300 mg q.i.d. for rheumatoid arthritis with endoscopic evidence of duodenal and/or gastric inflammation were randomized to misoprostol 200 mcg q.i.d. or placebo for 8 weeks while continuing to take aspirin. The study evaluated the potential interference of misoprostol on aspirin efficacy in these patients with rheumatoid arthritis by analyzing joint tenderness, joint swelling, clinician clinical assessment, patient assessment, changes in ARA classification, changes in hand grip strength, changes in duration of the morning. stiffness, patient assessment pain at rest, movement, interference with daily activities and ESR. Misoprostol did not affect the efficacy of aspirin in these patients with rheumatoid arthritis.

Misoprostol is indicated to reduce the risk of NSAIDs (Non-Steroidal Anti-Inflammatory Drugs, including Aspirin) induced gastric ulcers in patients at high risk of ulcer-related complications, e.g. the elderly and those with concomitant debilitating disease, as well as patients at high risk of developing stomach ulcers, such as patients with a history of ulcers. Misoprostol has not been shown to reduce the risk of duodenal ulcers in patients taking NSAIDs. Misoprostol should be taken during NSAID therapy. Misoprostol has been shown to reduce the risk of stomach ulcers in 3-month controlled studies. Compared to placebo, it had no effect on gastrointestinal pain or discomfort associated with NSAID use.

See framedWARNINGS.

Pregnant women should not take misoprostol to reduce the risk of ulcers caused by nonsteroidal anti-inflammatory drugs (NSAIDs).

Misoprostol should not be taken by anyone with a history of prostaglandin allergy.

See framedWARNINGS.

For hospital use only if misoprostol is used for cervical ripening, induction of labour, or for the treatment of severe postpartum bleeding, which is outside the approved indication.

Misoprostol should be used with caution in patients with pre-existing cardiovascular disease.

Information for patients

Women of childbearing age taking misoprostol to reduce the risk of NSAID-induced ulcers should be advised not to be pregnant when misoprostol treatment is started and to use an effective method of contraception while taking misoprostol.

See framedWARNINGS.

Misoprostol is for use in combination with non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin, to reduce the chance of developing an NSAID-induced peptic ulcer.

Misoprostol should only be taken as prescribed by your doctor.

If the patient has questions or problems with misoprostol, the doctor should be contacted immediately.

THE PATIENT SHOULD NOT GIVE MISOPROSTOL TO OTHERS.Misoprostol is prescribed for a patient's specific condition, it may not be the right treatment for another person, and it could be dangerous for another person if they become pregnant.

A patient information leaflet is included on the misoprostol packaging that the patient receives from the pharmacist. The patient should read the package insert before taking misoprostol and each time the prescription is renewed, as the package insert may have been revised.

Keep misoprostol out of the reach of children.

Misoprostol can cause birth defects, miscarriage (sometimes incomplete), premature birth, or uterine rupture if given to pregnant women.

Misoprostol is only available as a single-dose container with a patient information leaflet. To seePatient informationat the end of this mark.

Drug Interactions

To seeClinical Pharmacology.Misoprostol has not been shown to interfere with the beneficial effects of aspirin on the signs and symptoms of rheumatoid arthritis. Misoprostol has no clinically significant effects on the absorption, blood levels and antiplatelet effects of therapeutic doses of aspirin. Misoprostol has no clinically significant effect on the kinetics of diclofenac or ibuprofen.

Prostaglandins such as misoprostol may potentiate the activity of oxytocin, especially if given less than 4 hours before starting oxytocin treatment. Concomitant use is not recommended.

Animal Toxicology

A reversible increase in the number of normal gastric surface epithelial cells occurred in the dog, rat and mouse. No such increase was seen in people who received misoprostol for up to 1 year.

The apparent response of female mice to misoprostol in long-term studies at a dose 100 to 1000 times the human dose was hyperostosis, predominantly of the medulla sternebrae. Hyperostosis did not occur in long-term studies in dogs and rats and was not observed in humans treated with misoprostol.

Carcinogenesis, mutagenesis, impaired fertility

There was no evidence of an effect of misoprostol on the occurrence or incidence of tumors in rats given daily doses up to 150 times the human dose for 24 months. Similarly, there was no effect of misoprostol on the appearance or prevention of tumors in mice given daily doses up to 1000 times the human dose for 21 months. The mutagenic potential of misoprostol has been tested in several casesin vitrotests, all of which were negative.

When misoprostol was administered to male and female breeding rats at doses ranging from 6.25 times to 625 times the maximum recommended human therapeutic dose, it caused dose-related pre- and post-implantation losses and a significant reduction in the number of live pups born at the highest dose. These findings point to the possibility of a general adverse effect on male and female fertility.


Teratogenic effects

See framedWARNINGS.Congenital anomalies sometimes associated with fetal death have been reported following unsuccessful use of misoprostol as an abortifacient, but the drug's teratogenic mechanism has not been proven. Several reports in the literature have associated the use of misoprostol during the first trimester of pregnancy with cranial abnormalities, cranial nerve palsies, facial deformities and limb abnormalities.

Misoprostol is not fetotoxic or teratogenic in rats and rabbits at doses 625 and 63 times higher than the human dose.

Non-teratogenic effects

See framedWARNINGS. Misoprostol can endanger pregnancy (may cause miscarriage) and thus harm the fetus when given to a pregnant woman. Misoprostol can cause uterine contractions, uterine bleeding and expulsion of the products of conception. Abortions caused by misoprostol may be incomplete. If a woman becomes pregnant or becomes pregnant while taking this drug, the drug should be discontinued and the patient should be advised of the potential hazard to the fetus in order to reduce the risk of NSAID-induced ulcers.

Rad and porod

Misoprostol can cause or increase uterine contractions. Vaginal administration of misoprostol, off-label, is used as a cervical ripening agent, for labor induction, and for the treatment of severe postpartum bleeding in the presence of uterine atony. The major adverse effect of the use of misoprostol in obstetrics is uterine tachysystole, which may progress to uterine tetany with marked impairment of uteroplacental blood flow, uterine rupture (requiring surgical repair, hysterectomy and/or salpingo-oophorectomy) or amniotic fluid embolism and lead. to adverse cardiac changes in the fetus. Uterine activity and fetal status should be monitored by trained obstetric personnel in a hospital setting.

The risk of uterine rupture associated with the use of misoprostol during pregnancy increases with advancing gestational age and with previous uterine surgery, including cesarean delivery. High multiparity also appears to be a risk factor for uterine rupture.

Off-label misoprostol use may also be associated with meconium passage, meconium-colored amniotic fluid, and caesarean section. Maternal shock, maternal death, fetal bradycardia and fetal death have also been reported with the use of misoprostol.

Misoprostol should not be used in the third trimester in women with a history of cesarean section or major uterine surgery due to the increased risk of uterine rupture. Misoprostol should not be used in cases where uterotony is generally contraindicated or where uterine hyperstimulation is considered inappropriate, such as pelvic disproportion, large multiparity, hypertonic or hyperactive uterine patterns, or fetal distress when delivery is not on hands or when a surgical procedure is more appropriate.

The effect of misoprostol on the subsequent growth, development and functional maturation of the infant when misoprostol is used for cervical ripening or labor induction has not been established. Data on the effect of misoprostol on the need for forceps or other intervention are not known.

The use of misoprostol to treat postpartum bleeding has been associated with reports of high temperatures (over 40 degrees Celsius or 104 degrees Fahrenheit) accompanied by effects on the autonomic and central nervous system, such as tachycardia, disorientation, agitation and convulsions. These fevers were transient. Supportive therapy should be determined by the patient's clinical picture.

Breastfeeding mothers

Misoprostol is rapidly metabolised in the mother to misoprostol acid, which is biologically active and is excreted in breast milk. There are no published reports of misoprostol side effects in breastfed infants of mothers taking misoprostol. Caution should be exercised when misoprostol is given to nursing mothers.

Use in children

The safety and efficacy of misoprostol in pediatric patients have not been established.

The following have been reported as side effects in subjects receiving misoprostol:


(Video) Tab: Cytotec 💊 | Cytotec Tablet - Misoprostol tablet how to use | Misoprostol 200 mcg Tablet Uses

In subjects who received 400 or 800 mcg of misoprostol daily during clinical studies, the most common gastrointestinal adverse reactions were diarrhea and abdominal pain. The frequency of diarrhea at a dose of 800 mcg in controlled studies in patients taking NSAIDs ranged from 14-40%, and in all studies (more than 5000 patients) it averaged 13%. Abdominal pain occurred in 13-20% of patients in NSAID studies and approximately 7% in all studies, but there was no consistent difference compared to placebo.

Diarrhea was dose dependent and usually started early during treatment (after 13 days), usually resolved spontaneously (often resolved after 8 days), but sometimes required discontinuation of misoprostol (2% of patients). Rare cases of severe diarrhea leading to severe dehydration have been reported. Patients with an underlying condition such as inflammatory bowel disease or those in whom dehydration, should it occur, would be dangerous should be carefully monitored if misoprostol is prescribed. The frequency of diarrhea can be reduced by taking it after meals and at bedtime and by avoiding the concomitant use of misoprostol with magnesium-containing antacids.


Women receiving misoprostol during clinical trials reported the following gynecological disorders: bleeding (0.7%), cramps (0.6%), hypermenorrhea (0.5%), menstrual disorder (0.3%), and dysmenorrhea (0. 1%). Postmenopausal vaginal bleeding may be associated with the use of misoprostol. If it appears, diagnostic examination should be performed to exclude gynecological pathology. (See boxWARNINGS.)


There were no significant differences in the safety profile of misoprostol in approximately 500 patients with ulcers aged 65 years or older compared to younger patients.

Additional side effects that have been reported are categorized as follows:

Frequency greater than 1%

In clinical trials, the following adverse reactions were reported by more than 1% of subjects receiving misoprostol and may be causally related to the drug: nausea (3.2%), flatulence (2.9%), headache (2.4 %), dyspepsia (2.0%), vomiting (1.3%) and constipation (1.1%). However, there were no significant differences between the incidence of these events for misoprostol and placebo.

Causal relationship unknown

The following side effects have been reported rarely. Causal relationships between misoprostol and these events have not been established, but cannot be excluded:

The body as a whole:pain, asthenia, fatigue, fever, chills, stiffness, weight changes.

Skin:rash, dermatitis, alopecia, pallor, breast pain.

Special senses:abnormal taste, abnormal vision, conjunctivitis, deafness, tinnitus, ear pain.

Breathing:upper respiratory tract infection, bronchitis, bronchospasm, shortness of breath, pneumonia, epistaxis.

Cardiovascular:chest pain, edema, diaphoresis, hypotension, hypertension, arrhythmia, phlebitis, increased cardiac enzymes, syncope, myocardial infarction (some fatal), thromboembolic events (e.g. pulmonary embolism, arterial thrombosis and stroke).

Gastrointestinal:GI bleeding, GI inflammation/infection, rectal disorder, hepatobiliary function abnormal, gingivitis, reflux, dysphagia, amylase increased.

Hypersensitivity:anaphylactic reaction

Metabolic:glycosuria, gout, increased nitrogen, increased alkaline phosphatase.

Genito-urinary:polyuria, dysuria, haematuria, urinary tract infection.

Nervous System/Psychiatric:anxiety, change in appetite, depression, drowsiness, dizziness, thirst, impotence, loss of libido, increased sweating, neuropathy, neurosis, confusion.

Musculoskeletal System:arthralgia, myalgia, muscle spasms, stiffness, back pain.

Blood clotting:anemia, abnormal differential, thrombocytopenia, purpura, increased ESR.

The toxic dose of misoprostol in humans has not been established. Cumulative total daily doses of 1600 mcg were tolerated and only symptoms of gastrointestinal discomfort were reported. In animals, acute toxic effects include diarrhoea, gastrointestinal lesions, focal cardiac necrosis, hepatic necrosis, renal tubular necrosis, testicular atrophy, respiratory distress and central nervous system depression. Clinical signs that may indicate overdose are sedation, tremors, convulsions, dyspnoea, abdominal pain, diarrhoea, fever, palpitations, hypotension or bradycardia. Symptoms should be treated with supportive therapy.

It is not known whether misoprostol acid is dialysable. However, since misoprostol is metabolized as a fatty acid, dialysis is probably not an appropriate treatment for overdose.

The recommended oral dose of misoprostol for adults to reduce the risk of stomach ulcers caused by NSAIDs is 200 mcg four times a day with food. If this dose is not tolerated, a 100 mcg dose may be used. (To seeClinical Pharmacology: Clinical Studies.) Misoprostol should be taken during treatment with NSAIDs as recommended by the doctor. Misoprostol should be taken with a meal and the last dose of the day should be taken at bedtime.

Kidney damage

Dosage schedule adjustment in patients with renal impairment is not routinely required, but the dose may be reduced if the 200 mcg dose is not tolerated. (To seeClinical Pharmacology.)

Misoprostol Tablets, 200 mcg are available as white, round, scored, flat, bevelled edge tablets, marked "N" above the score and "444" below the score and plain on the reverse.

Read these instructions before taking misoprostol and each time your prescription is renewed, as the instructions may change.

Your doctor prescribes misoprostol to reduce the chance of getting an ulcer due to the arthritis/pain medication you are taking.

To reduce the risk of NSAID-induced ulcers, do not use misoprostol if you are pregnant. (See boxWARNINGS.) Misoprostol can cause miscarriage (sometimes incomplete which can lead to dangerous bleeding and require hospitalization and surgery), premature birth, or birth defects. It is also important to avoid pregnancy while taking this medicine and for at least one month or one menstrual cycle after you stop taking it. Misoprostol can cause the uterus to rupture (uterine rupture) during pregnancy. The risk of uterine rupture increases as your pregnancy progresses and if you have had surgery on your uterus, such as a caesarean section. The rupture (tearing) of the uterus can lead to severe bleeding, hysterectomy, and/or maternal or fetal death.

If you become pregnant during treatment with misoprostol, stop taking misoprostol and contact your doctor immediately. Keep in mind that it is possible to get pregnant even if you are using birth control. If this happens, stop taking misoprostol and contact your doctor immediately.

Misoprostol can cause diarrhoea, abdominal cramps and/or nausea in some people. In most cases, these problems arise during the first few weeks of treatment and disappear after about a week. You can minimize possible diarrhea by taking misoprostol with food.

Because these side effects are usually mild to moderate and usually disappear within a few days, most patients can continue to take misoprostol. If you have long-term problems (longer than 8 days), or if you have severe diarrhoea, cramps and/or nausea, please contact your doctor.

Take misoprostol only as directed by your doctor.

Do not give misoprostol to anyone else. It is prescribed for your specific condition, may not be the right treatment for another person, and would be dangerous if the other person is pregnant.

This information sheet does not cover all possible side effects of misoprostol. This Patient Information Leaflet does not discuss the side effects of your arthritis/pain medicines. Consult your doctor if you have any questions.

Keep out of reach of children.
