Gastrointestinal side effects of risedronate have included diarrhea, nausea, flatulence, gastrointestinal disorder, constipation, rectal disorder and tooth disorder.

Gastrointestinal side effects of calcium carbonate have included rebound hyperacidity, constipation (6% to 37%) and gallstones (rarely).[Ref]

During phase 3 clinical studies of risedronate, patients with a history of upper gastrointestinal (GI) disease or abnormalities were not excluded. Severe upper GI side effects were not noted. Patients using NSAIDs or aspirin were also included in phase 3 clinical studies. GI side effects in patient using concomitant NSAIDs or aspirin were higher than in non users.

Rebound hyperacidity has been associated with calcium salt antacids. This side effect does not appear to be due to the acid buffering capacity of calcium carbonate, but is a consequence of a specific action of calcium on the parietal cell. Rare cases of calcium carbonate gallstones have been reported in the pediatric literature.[Ref]
