4.4 Special warnings and precautions for use

Keep out of reach and sight of children. If you take too many tablets, your symptoms persist or worsen, or you experience any undesirable effects with this product, seek medical advice. If symptoms persist consult your doctor or pharmacist.

Use with caution in diseases associated with hypercalcaemia such as sarcoidosis and some malignancies and in patients with a history of renal calculi.

This medicine contains glucose and sucrose. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrose-isomaltase insufficiency should not take this medicine.

4.5 Interaction with other medicinal products and other forms of interaction

Antacids of this type are known to decrease the absorption of concomitantly administered drugs due to absorption or delaying of gastric emptying or alkalinisation of gastric juice. However the activity of cardiac glycosides such as digoxin may be increased due to the presence of calcium.

Calcium may reduce the absorption of tetracyclines, eltrombopag, bisphosphonates, fluoride, oral iron, zinc, levothyroxine and some fluoroquinolones.

Thiazide diuretics may reduce urinary calcium excretion and cause hypercalcaemia. Vitamin D increases the gastrointestinal absorption of calcium and can cause hypercalcaemia. Plasma-calcium concentrations should be monitored in patients receiving calcium together with thiazide diuretics or Vitamin D.

Antacids may damage enteric coatings designed to prevent dissolution in the stomach.

Interactions may be minimised by ensuring that Setlers Antacid Chewable Tablets Peppermint Flavour are not taken at the same time as, nor within three hours of other medications.

4.6 Fertility, pregnancy and lactation

Animal studies are insufficient with respect to effects on pregnancy, embryonal foetal development, parturition and postnatal development (see section 5.3). The potential risk for humans is unknown.

Caution should be exercised when prescribing to pregnant women.

4.7 Effects on ability to drive and use machines

None known.

4.8 Undesirable effects

Calcium compounds can cause gastro-intestinal disturbances including flatulence and constipation.

Calcium-containing antacids can induce rebound acid secretion; however, this is unlikely to be of clinical significance in normal use.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

Prolonged excessive ingestion of calcium carbonate may lead to hypercalcaemia. Patients with renal impairment are most at risk. Alkalosis is a potential but rare risk. There have been rare reports of the milk-alkali syndrome.

Symptoms of hypercalcaemia may include anorexia, nausea, vomiting, constipation, abdominal pain, muscle weakness, mental disturbances, polydipsia, polyuriua, nephrocalcinosis, renal calculi and, in severe cases, cardiac arrhythmias and coma.

Treatment should be aimed at lowering serum calcium levels and may include full hydration, monitoring of other electrolytes and other standard symptomatic and supportive measures.
