It has been shown that antacids which contain calcium or magnesium may form complexes with certain substances e.g. antibiotics (such as tetracyclines and quinolones), and cardiac glycosides (e.g. digoxin), bisphosphonates, dolutegravir, levothyroxine, and eltrombopag, resulting in decreased absorption. This should be borne in mind when concomitant administration is considered. Caution should be exercised in patients with mild to moderate impairment of renal function (see section 4.3 – contraindication in severe renal insufficiency). If Rennie is used in such patients, plasma calcium and magnesium levels should be regularly monitored. No increased risks of congenital defects have been observed after the use of this product during pregnancy.

Hypersensitivity reactions have very rarely been reported. Clinical symptoms may include rash, urticaria, pruritus, angioedema, difficulty in breathing and anaphylaxis. Long term use of high doses can cause high blood levels of calcium and magnesium, especially in people with kidney conditions. Symptoms of this may include nausea, vomiting, upset stomach, constipation, diarrhoea, tiredness, muscular weakness, headache, kidney problems and impaired sense of taste. Long term uses at high doses can result in undesirable effects such as hypercalcaemia, hypermagnesaemia and milk-alkali syndrome, especially in patients with renal insufficency. Thiazide diuretics reduce the urinary excretion of calcium. Due to an increased risk of hypercalcaemia, serum calcium should be regularly monitored during concomitant use of thiazide diuretics.
