Studies have shown that domperidone may be associated with a small increased risk of serious cardiac side effects.
These risks may be higher in patients older than 60 years and in patients who receive daily oral doses of more than 30 mg.
Domperidone should be used at the lowest effective dose for the shortest possible time
Maximum treatment duration should not exceed one week
Domperidone is contra-indicated in patients who are taking concomitant medication known to cause QT prolongation (such as ketoconazole and erythromycin)

Helicobacter pylori infection |
|
|
|
For initial treatment, a one-week triple-therapy regimen that comprises a proton pump inhibitor, clarithromycin, and either amoxicillin or metronidazole can be used.
If a patient has been treated with a macrolide for other infections, a regimen containing a proton pump inhibitor, amoxicillin and metronidazole is preferred for initial therapy.
These regimens eradicate H. pylori in about 85% of cases. There is usually no need to continue antisecretory treatment (with a proton pump inhibitor or H2-receptor antagonist), however, if the ulcer is large, or complicated by haemorrhage or perforation, then antisecretory treatment is continued for a further 3 weeks.
Consult BNF and the Antibiotic Policy for further details and dosing information.
Treatment failure usually indicates antibacterial resistance or poor compliance - consult gastroenterologist for advice |

Description |

|
Drugs designated amber are suitable for shared care arrangements under a shared care protocol.
Prescribing may be transferred from secondary to primary care once the patient is stabilised and agreed shared care arrangements have been established. Alternatively primary care may initiate under the supervision of secondary care if this option is given in the shared care document. It is recommended that shared care arrangements should be drawn up following local discussion and agreement by prescribing parties.
|

|
These products have been reviewed by the GM Joint Formulary Group and have been deemed not suitable for prescribing for adults in primary or secondary care within Greater Manchester. These decisions have been made on the basis of safety, efficacy and cost-effectiveness of the products. |

|
Not used
|

|
Drugs designated green1 are suitable for initiation and ongoing prescribing within primary care. |

|
Drugs designated green2 can be initiated by primary care following written or verbal advice from a specialist and then be subsequently safely prescribed in primary care with little or no monitoring required. |

|
Drugs designated green3 are suitable for on-going prescribing within primary care after specialist initiation and an initial review (unless specified) in secondary care. Little or no monitoring is required. |

|
Not suitable for routine prescribing but may be suitable for a defined patient population. Whilst prescribers should think very carefully before prescribing or recommending any of the products on the grey list, there may be exceptional instances when the use of one of these products is necessary for a particular patient. |

|
Drugs designated red are considered to be specialist medicines and prescribing responsibility for these medicines should normally remain with the consultant or specialist clinician. These drugs should not be initiated or prescribed in primary care. It is recommended that the supply of these specialist medicines should be organised via the hospital pharmacy, this may include arranging for supply via a home care company.
