If Helicobacter pylori infection demonstrated, treat with eradication therapy, as outlined in the guideline here.
Omeprazole oral 40mg once daily for 4 – 8 weeks or
Lansoprazole oral 30mg once daily for 4 – 8 weeks
If the ulcer is associated with non-steroidal anti-inflammatory drug (NSAID):
If the NSAID needs to be continued or restarted, use in combination with a PPI e.g.:
omeprazole oral 20mg once daily or lansoprazole oral 30mg once daily irrespective of H. pylori status.
If the patient is unable to take oral therapy give:
omeprazole 40mg by slow IV infusion over 20-30 minutes. NB: Only available licensed preparation is for infusion.
If patient has had endoscopic haemostasis for a bleeding ulcer give:
omeprazole infusion, initial 80 mg dose (give 80mg in 100ml sodium chloride 0.9% infused over 40 - 60 minutes)
then followed by:
continuous infusion of 8 mg/hour for 72 hours (make up 80mg in 100ml sodium chloride 0.9%, infuse at 10ml (8mg) per hour over 10 hours for a total of 72 hours, a total of 8 infusion bags have to be prepared)
then followed by oral therapy:
omeprazole oral 40mg twice daily for 2 weeks then 40mg daily for 6 weeks.
N.B. Continuous infusion of omeprazole is an unlicensed use. Bags should only be prepared immediately before use as no stability data beyond this time period.
