The recommended dose is 40mg once a day at bedtime. The duration of treatment will normally be between 4-8 weeks. In most cases the ulcer will heal with this treatment within 4 weeks. For treatment of a recurrent ulcer, your doctor may decide it is necessary to take 20mg a day at bedtime.

The recommended dose is 20mg every six hours. Some patients may require higher doses. Your doctor will decide if this is necessary.
Reflux Oesophagitis
The recommended dose for treating the symptoms of this condition is 20mg twice a day, to be taken for as long as is deemed necessary.
For treatment of an ulcer associated with Reflux Oesophagitis, the recommended dose is 40mg twice a day to be taken for 6-8 weeks.
If long-term treatment of Reflux Oesophagitis is required, the recommended dose is 20mg twice a day. This is not usually recommended beyond 6 months.
