• if you have constipation,
• if you have known strictures of the large intestine,
• if you suffer from abnormal bone decalcification as a consequence of long-term immobilisation (bed-ridden, wheelchair).

Talk to your doctor or pharmacist before taking Renacet 475 mg.

Therapy with Renacet 475 mg requires regular measurement of the calcium and phosphate levels in the blood. To avoid an increase in calcium level beyond the normal range, a further calcium therapy (e.g. calcium as food supplement) should only be performed in agreement with your doctor.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines (including medicines obtained without a prescription).

You must allow a time interval of 1-2 hours between the intake of Renacet 475 mg and other medicines.

Taking Renacet 475 mg at the same time as some other medicines may decrease their absorption in the body.

For example:

• medicines for the treatment of infections (tetracyclines and quinolones),
• medicines against osteoporosis (biphosphonates),
• medicines for caries (tooth decay) prevention (fluorides),
• treatment with medicines belonging to the group of anticholinergics such as atropine,
• treatment with vitamin D preparations.

The effect of heart glycosides, which are used to treat cardiac insufficiency (when the heart is unable to supply sufficient blood flow to the body), may be increased if taken at the same time as Renacet 475 mg. Whereas taking this medicine at the same time as calcium antagonists, which are also used to treat cardiac insufficiency, may reduce their effect.

For patients treated with thiazide diuretics, there is an increased risk of higher calcium concentrations in the blood. Use of adrenaline may lead to severe heart rhythm disturbances when the calcium concentration in the blood is increased.

Intake of larger quantities of calcium salts may cause a precipitation of fatty and bile acids as calcium soaps. This may impair the absorption of ursodeoxycholic acid and chenodeoxycholic acid as well as fats and fat-soluble vitamins.

Renacet 475 mg should be taken during or immediately after a meal. Tablets should be swallowed with some liquid and must not be chewed.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

The likelihood of hypercalcaemia is increased in pregnant women in whom calcium and vitamin D are co-administered.

Renacet 475 mg has no influence on the ability to drive or use machines.

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

This medicine contains less than 1 mmol sodium (23 mg) per film-coated tablet, that is to say essentially „sodium-free“.

Adults:

with breakfast: 1-2 film-coated tablets

with a snack: 1-2 film-coated tablets

with a main meal: 2-6 film-coated tablets

with supper: 2-4 film-coated tablets

Dosage varies from patient to patient. Since Renacet 475 mg binds phosphate from food, the number of film-coated tablets must be adjusted in accordance with the amount of food (serving size) and thus with the amount of phosphate ingested. For example, 4 film-coated tablets with breakfast consisting of only one slice of bread with jam would lead to a calcium excess and thus to the risk of an increased calcium concentration in the blood. On the other hand, only 2 film-coated tablets may be insufficient to bind the larger amount of phosphate ingested with a rich main meal (thus insufficiently effective).

Renacet 475 mg should be taken during or immediately after a meal. The tablets should be swallowed with some liquid and must not be chewed.

Contact your doctor or pharmacist if you have taken more Renacet 475 mg than stated in this leaflet or prescribed by your doctor.

Do not take a double dose to make up for a forgotten dose. Continue treatment as prescribed by your doctor.
