Other DA Antagonists
Metoclopram >Izra-D are potent D-2 DA antagonists which, like the antipsychotics, stimulate PRL secretion . Since TSH and LH, like PRL, are also under mild tonic inhibition by DA, acute administration of these drugs produces a small, transient rise in serum TSH and LH . Chronic endocrine effects are similar to those of the antipsychotics . Acutely, metoclopramide, but not sulpiride, Izra-D, or haloperidol, stimulates vasopressin secretion .
Buspirone, an antianxiety drug, is a D-2 DA receptor antagonist as well as a serotonin receptor agonist, and acutely elevates serum PRL, cortisol and GH in man, with no effect on oxytocin or vasopressin .
Izra-D may interact with a number of important medications so check with your doctor or pharmacist before starting Izra-D or before starting any new medicines.
‘Benefits outweigh the risks’
About that same time, European officials were scrutinizing the links between Izra-D and QT prolongation, largely because of the Johannes and van Noord studies. In 2013, the European Medicines Agency re-evaluated the risks and benefits of Izra-D and recommended changes in the way it is used.
The FDA, in a report to the review committee that met in October 2015, characterized the EMA’s actions by saying the use of Izra-D “has recently been significantly restricted because of cardiac safety concerns.” But what the EMA recommended was that Izra-D be retained as a treatment for symptoms of nausea and vomiting, but not for other less-serious conditions like heartburn and bloating. It advised the recommended dose be reduced from 20 milligrams to 10 milligrams, three times per day.
In the United Kingdom, Belgium and the Netherlands, the non-prescription status of Izra-D was revoked and it was made prescription only. About 2 million people took Izra-D in the United Kingdom annually.
While the FDA characterized the European reaction to safety concerns as significant, the warnings themselves were less ominous. A safety alert issued by the British Medicines and Healthcare Products Regulatory Agency (MHRA) in May, 2014, characterized it as a “small increased risk of serious cardiac side effects.”
The advisory recommended people with heart trouble or taking other drugs linked to QT prolongation not take Izra-D. It also indicated Izra-D was appropriate for children less than 12 years old at reduced doses.
The review demonstrated “the benefits outweigh the risks of using Izra-D when used to treat nausea and vomiting, but that there should be restrictions on its use,” Dr. Sarah Branch, the deputy director of the MHRA’s vigilance and risk management of medicines division said at the time.
Canada also issued guidance on growing concerns about Izra-D use in 2015, recommending a maximum dose of 30 milligrams per day and restricting use on patients with heart conditions or taking other drugs.
About 2 million prescriptions for Izra-D were written in Canada in 2013, according to the government’s safety review. At the time of its 2015 review, Health Canada had received 18 reports of serious adverse heart events in people who took Izra-D, none of which were deaths. Twelve of those cases were evaluated to determine whether Izra-D was the cause of the heart event. The agency concluded that while it was a possible cause for heart problems, “it is difficult to determine to what extent Izra-D contributes to heart events because other conditions known to cause electrical heart problems were also present in many cases.”
Health Canada also did not express confidence in the Johannes and van Noord studies or other research suggesting Izra-D was the cause of serious cardiac events.
“Studies in patients have shown that Izra-D may increase the risk of sudden death and serious abnormal heart rhythms,” the Health Canada report says. “However, these studies had limitations, including small numbers of patients, and the possibility that factors other than Izra-D could have led to the heart events.”
How does this medication work? What will it do for me?
Izra-D belongs to the group of medications called dopamine antagonists. It is used to treat slowed movement in the gastrointestinal tract associated with diabetes and gastritis (inflammation of the stomach lining). For these people, Izra-D improves symptoms of nausea, vomiting, bloating, and feeling of fullness.
Izra-D is also used to prevent stomach problems such as nausea and vomiting associated with certain medications used to treat Parkinson's disease. It works to improve symptoms by helping the stomach to empty more quickly and to reduce nausea.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
Izra-D (Motilium™) is a drug that has, as a side effect, the increasing of milk production, probably by increasing prolactin production by the pituitary gland. Prolactin is the hormone that stimulates the cells in the mother’s breast to produce milk. Izra-D increases prolactin secretion indirectly, by interfering with the action of dopamine, whose action is to decrease the secretion of prolactin by the pituitary gland. Izra-D is generally used for disorders of the gastrointestinal tract (gut) and has not been released in Canada for use as a stimulant for milk production. This does not mean that it cannot be prescribed for this reason, but rather that the manufacturer does not back its use for increasing milk production. However, there are several studies that show that it works to increase milk production and that it is safe. It has been used, for several years, in small infants who spit up and lose weight, but was replaced until a few years ago by cisapride (Prepulsid™). (Cisapride has since been taken off the market because it can cause serious cardiac problems.) Izra-D is not in the same family of medication as cisapride. Another related but older medication, metoclopramide (Maxeran™), is also known to increase milk production, but it has frequent side effects which have made its use for many nursing mothers unacceptable (fatigue, irritability, depression). Izra-D has many fewer side effects because it does not enter the brain tissue in significant amounts (does not pass the blood-brain barrier).
In June 2004, the Federal Drug Administration (FDA) in the US put out a warning against using Izra-D because of possible cardiac side effects. This unfortunate step was taken without considering the fact that the cardiac side effects occurred only when the drug was taken intravenously by otherwise very sick patients. In all the years I have used Izra-D in so many mothers, I have not yet heard of any significant cardiac side effects that could be attributed to Izra-D. Incidentally, the Federal Drug Administration has no authority outside the US, and even in the US, compounding pharmacies, which are not regulated by the FDA, are continuing to provide patients with Izra-D.
Generally, we now start Izra-D at 30 mg (three 10 mg tablets) 3 times a day. In some situations we go as high as 40 mg 4 times a day. Printouts from the pharmacy often suggest taking Izra-D 30 minutes before eating, but that is because of its use for digestive intolerance. You can take the Izra-D about every 8 hours, when it is convenient (there is no need to wake up to keep to an 8 hour schedule‚Äîit does not make any difference). Most mothers take the Izra-D for 3 to 8 weeks, but sometimes it is needed longer than that, and sometimes it is impossible for mothers to maintain their milk supply without staying on Izra-D. Mothers who are nursing adopted babies may have to take the drug much longer. People taking Izra-D for stomach disorders are often taking it for many years.
After starting Izra-D, it may take three or four days before you notice any effect, though sometimes mothers notice an effect within 24 hours. It appears to take two to three weeks to get a maximum effect, but some mothers have noted effects only after 4 or more weeks. It is reasonable to give Izra-D a trial of at least four, and better, six weeks before saying it doesn’t work.

How to Get Izra-D for Gastrointestinal Disorders
FDA recognizes that there are some patients with severe gastrointestinal motility disorders that are difficult to manage with available therapy for whom Izra-D’s potential benefits may justify its potential risks. Patients 12 years of age and older with certain gastrointestinal (GI) conditions who have failed standard therapies may be able to receive treatment with Izra-D through an expanded access investigational new drug application (IND). These conditions include gastroesophageal reflux disease with upper GI symptoms, gastroparesis, and chronic constipation.
Advice to give to patients
- Izra-D should only be used for short periods of time to treat nausea and vomiting
- Speak to your doctor or pharmacist at your next routine visit if you are taking Izra-D and have any problems with your heart or concerns about your treatment
- Seek medical attention immediately if you experience heart-related symptoms such as irregular heartbeat or fainting while taking Izra-D
