Domperon General Information

What is Domperon used for?

Domperon 10 is used to treat nausea and vomiting and help relieve symptoms like bloating, fullness, heartburn and flatulence that cause discomfort when the digestive system is out of rhythm or you have eaten too much. Domperon 10 can also be used to relieve symptoms of nausea caused by some medications, such as anti-cancer drugs and medications used for Parkinson’s disease. Another use for Domperon is to increase breast milk production, as a side effect of its intended use.

How does Domperon work?

Domperon 10 contains domperidone, a dopamine antagonist that acts as an antiemetic (prevents nausea and vomiting) and as a gastrokinetic (stimulates gastrointestinal mobility). Nausea and vomiting are triggered when the chemoreceptor trigger zone (CTZ) in the brain is stimulated, and this causes nerve impulses to be sent to area postrema or vomiting centre of the brain, to induce the vomiting reflex. The CTZ can be activated by two mechanisms; either indirectly by transmission of nerve impulses sent to the brain from the stomach when it has been irritated, or directly by chemicals or drugs that are circulating in the blood and stimulate receptors in the brain. Domperon 10 works by blocking the action of the chemical messenger dopamine and this stops the transmission of messages from the irritated or upset stomach to the brain, preventing the brain triggering the vomiting response. Domperon 10 also blocks the same chemical messengers in the upper digestive system. This relieves dysmobility, which is when food processing slows down causing uncomfortable symptoms. Domperon 10 restores the natural rhythm of muscle contraction and relaxation in the stomach, which helps push food through the digestive system and prevents vomiting.

How does Domperon help with breastfeeding?

If you are having trouble producing enough breast milk you can use Domperon to help with breastfeeding. Domperidone 10mg, the active ingredient of Domperon, increases blood levels of the hormone prolactin, which stimulates milk production in a new mother’s breast cells. This is an indirect result of blocking the chemical messenger dopamine, which is also how Domperon prevents nausea and vomiting. Domperon does pass from the blood into breast milk, however, it is present in small amounts and there is no indication that it will harm the baby. Domperon has fewer side effects than metoclopramide, which is another medication used for stomach problems that also stimulates milk production.

Domperon for increasing breast milk production

Domperon can be used to increase breast milk production as it has been found to increase blood levels of the hormone prolactin, which stimulates milk production in a new mother’s breast cells. This is an indirect result of blocking the chemical messenger dopamine, which is also how Domperon prevents nausea and vomiting. Domperon 10 does pass from the blood into your breast milk, however, it is present in small amounts and there is no indication that it will harm the baby.

What are the side effects of Domperon?

The most commonly reported side effects when taking Domperon 10 include: headache, abdominal cramps and dry mouth. Because Domperon does not cross the blood brain barrier it does not cause what are known as extrapyramidal side effects, like convulsion and involuntary muscle actions that can be associated with some dopamine blocking medications. However, for the same reason Domperon can increase the production of the hormone prolactin, which stimulates breast milk secretion, and this can cause breast enlargement (gynaecomastia) and temporary stoppage of periods (amenorrhoea). These side effects will stop as soon as you stop taking Domperon.

• have a condition where increasing gut motility could be harmful, such as gastrointestinal haemorrhage, mechanical obstruction or a perforation
• have a kidney or liver condition than causes impairment of renal or hepatic function
• have a pituitary tumour that causes over-production of prolactin (prolactinoma)
• are taking another medication that may interact with Domperon and prevent one or both drugs working effectively, such as the antifungals ketoconazole, fluconazole or voriconazole, antibiotics containing erythromycin, clarithromycin or telithromycin; amiodarone for rapid heart beat.
