Do not take Rennie:

Warnings and Precautions

Consult your doctor, pharmacist, or nurse before starting to take Rennie.

  • Avoid prolonged use.
  • Do not exceed the recommended dose (see section 3).
  • Consult your doctor or pharmacist before taking Rennie if you have kidney problems, as the administration of this medicine in subjects with altered renal function can cause hypercalcemia (high blood calcium levels) and metabolic alkalosis (milk-alkali syndrome).
  • If symptoms worsen or persist for more than 7 days, you should consult a doctor.
  • The medicine should not be taken with large amounts of milk or dairy products.

Children and Adolescents

Do not administer to children under 12 years old without consulting a doctor.

Taking Rennie with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Before taking Rennie, inform your doctor or pharmacist if you are taking any of the following medicines, as they may affect the efficacy of these medicines:

  • calcitonin,
  • sodium phosphate and other phosphates,
  • oral contraceptives,
  • thiazide diuretics (medicines used to increase urine excretion rate),
  • fluorides (medicines for the prevention of tooth decay),
  • amphetamines or quinidine,
  • salicylates (medicines with anti-inflammatory, analgesic, and antipyretic properties),
  • vitamin D,
  • heart medicines such as glycosides (digoxin, bisphosphonates, or dolutegravir),
  • levothyroxine (a thyroid hormone),
  • eltrombopag (a medicine used to increase the number of platelets),
  • other medicines prescribed by a doctor (e.g., etidronate, products containing iron, antidyskinetics, antimuscarinics, phenothiazines, benzodiazepines, ketoconazole, diflunisal, H2 antihistamines, sucralfate, oral anticoagulants derived from coumarin or indandione, antibiotics such as tetracyclines or quinolones), as they may interfere with its absorption.

It is recommended to space the administration of antacids with other medicines by 1 or 2 hours.

Interference with analytical tests

If you are going to undergo any analytical tests (including blood tests, urine tests, skin tests using allergens, etc.), inform your doctor that you are taking this medicine, as it may alter the results.

Taking Rennie with food and drinks

Like all antacids that contain calcium, it should not be taken with large amounts of milk or dairy products, as it may increase calcium or magnesium levels in the blood and cause milk-alkali syndrome.
