Q: What is Domperidone used for?

Domperidone is used to treat: Nausea Vomiting Gastroparesis (not FDA-approved in the U.S.)

Q: How does Domperidone work?

Mechanism of Action Domperidone is a type of medicine known as a dopamine antagonist. It works by blocking dopamine receptors in two main areas of the body: the upper digestive tract and the part of the brain that controls the vomiting reflex. Improving Digestive Movement In the stomach and intestines, domperidone helps coordinate the muscles to move food more efficiently. It works by: Increasing the strength and frequency of contractions in the stomach and bowel. Helping the stomach empty its contents into the small intestine more quickly. Improving the muscle tone at the entrance of the stomach to prevent food from moving backward. These actions help the digestive system process food more effectively, which can relieve symptoms like bloating, persistent fullness, and upper abdominal discomfort. Reducing Nausea Domperidone also acts on the chemoreceptor trigger zone, which is the part of the brain responsible for triggering the vomiting reflex. By blocking dopamine receptors in this specific area, the medication helps to prevent or reduce feelings of nausea and the urge to vomit. Because domperidone does not easily cross the blood-brain barrier, its effects are primarily limited to the digestive system and the specific brain region that regulates nausea, rather than affecting other parts of the central nervous system.

Q: Is Domperidone safe during pregnancy and breastfeeding?

Pregnancy There is limited information regarding the safety of using domperidone during pregnancy. While animal studies have shown some toxicity at very high doses, there are no adequate and well-controlled studies in pregnant women. Because the potential risks to a developing fetus are not fully understood, domperidone is typically only used during pregnancy if a healthcare provider determines that the potential benefits clearly outweigh the risks. Breastfeeding Domperidone is known to pass into breast milk in small amounts. This has led to several safety considerations and warnings from health authorities: Off-label use: Although domperidone is sometimes used off-label to increase milk production (lactation), the U.S. Food and Drug Administration (FDA) has issued specific warnings against this practice. Cardiac risks: The FDA's concern stems from reports of serious adverse events, including heart rhythm disorders and sudden cardiac arrest, in women using the drug for lactation. Infant safety: It is currently unknown if the small amount of the drug that passes into breast milk could cause side effects in a nursing infant. Individuals who are breastfeeding or planning to breastfeed should discuss the potential risks and benefits with their healthcare provider before using this medication. In many regions, domperidone is not approved for use by breastfeeding women due to these safety concerns.

Q: What forms and strengths does Domperidone come in?

Available Forms Domperidone is typically administered orally. The available forms include: Tablets: Solid oral tablets are the most common form. Oral Suspension: A liquid formulation is available for oral use. In the United States, domperidone is not FDA-approved and is not legally marketed. It may only be accessed through specific regulatory channels for patients with certain gastrointestinal conditions.
