From Dog

Cimetidine is an histamine H2-receptor antagonist that inhibits the production of stomach acid as well as having antiemetic properties.

Cimetidine is indicated for use in NSAID-induced oesophagitis[1], oesophageal strictures[2], gastritis associated with Helicobacter spp infection and as an antiemetic[3] and immunomodulator[4].

It does however appear to be pharmacologically less effective than omeprazole in reducing gastric acid production.

Recommended dose for use in dogs is 5 - 15 mg/kg given orally every 8 - 12 hours.

It appears to be safe when used long term and when in combination with other drugs.
