Side effects of Tritalac antacid tablets may include constipation and rebound hyperacidity, as reported by Drugs.com. Some less common side effects include hypercalcemia, which is a condition in which there is too much calcium in the blood, as well as kidney problems and gallstones.
The rare side effects of taking Titralac can sometimes be quite serious, according to Drugs.com. Patients should seek medical attention if they experience symptoms of a severe allergic reaction, such as a rash, hives, difficulty breathing or swelling of the mouth, face, lips or tongue while taking Tritalac antacid tablets.
Rebound hyperacidity can sometimes occur after taking Tritalac antacid tablets, according to Drugs.com. In addition, studies have shown that constipation occurs in between 6 and 37 percent of cases of people taking this kind of medication. Gallstones have also been noted by patients taking calcium carbonate tablets, although they are rare.
People occasionally develop hypercalcemia while taking calcium carbonate antacids over a long period. This side effect is much more likely in people who have damaged kidneys or who are receiving dialysis, according to Drugs.com. Hypercalcemia symptoms can include constipation, nausea, frequent urination and thirst, as well as fatigue and confusion, as reported by Mayo Clinic.
