Rationale for decision / comments
Antiemetics and Antinauseants
Dopamine receptor antagonistsDomperidoneIndication restricted to nausea and vomiting, new contraindications, and reduced dose and duration of use. See MHRA (December 2014) for Domperidone: risks of cardiac side effects.

A European review confirmed a small increased risk of serious cardiac side effects. A higher risk was observed particularly in people older than 60 years, people taking daily oral domperidone doses of more than 30 mg, and those taking QT-prolonging medicines or CYP3A4 inhibitors at the same time as domperidone.

The overall safety profile of domperidone, and in particular its cardiac risk and potential interactions with other medications, should be taken into account if there is a clinical need to use it at doses or durations greater than those authorised (eg, to control side effects of Parkinson’s disease treatment in some patients).
Domperidone is no longer licensed for use in children younger than 12 years or those weighing less than 35 kg. Results from a placebo-controlled study in children younger than 12 years with acute gastroenteritis did not show any difference in efficacy at relieving nausea and vomiting compared with placebo. See MHRA (December 2019) for Domperidone for nausea and vomiting: lack of efficacy in children; reminder of contraindications in adults and adolescents.
10mg tablet: £0.66 (30)Nausea and vomiting and acute migraine for adults and adolescents over 12 years of age and weighing 35 kg or more, the recommended maximum dose in 24 hours is 30 mg (10 mg up to three times a day)

The maximum treatment duration should not usually exceed one week.
1mg/ml oral suspension sugar free: £24.85 (200 ml)
Metoclopramide Restricted dose and duration of use. See MHRA (December 2014) for Metoclopramide: risk of neurological adverse effects.

The EU review has recommended changes that include a restriction to the dose and duration of use to help minimise the risk of potentially serious neurological adverse effects. The risk of acute neurological effects is higher in children than in adults.

In adults, metoclopramide remains indicated for: prevention of postoperative nausea and vomiting radiotherapy-induced nausea and vomiting delayed (but not acute) chemotherapy-induced nausea and vomiting symptomatic treatment of nausea and vomiting, including that associated with acute migraine (where it may also be used to improve absorption of oral analgesics).

In children, age 1–18 years, metoclopramide should only be used as a second-line option for prevention of delayed chemotherapy-induced nausea and vomiting, and for treatment of established postoperative nausea and vomiting.

Use of metoclopramide is contraindicated in children younger than 1 year.
