1. What is CALPEROS and what is it used for
CALPEROS 500 and CALPEROS 1000 contain calcium carbonate, which is a source of ionized calcium for the body.
Calcium is an element involved in the formation and mineralization of bone tissue throughout a person's life. It conditions proper nerve conduction and muscle excitability. It maintains the body's electrolyte balance and also affects the functioning of the heart muscle. It participates in the blood coagulation process. It affects the activity of a number of enzymes and also plays the role of a transmitter, thanks to which chemical, physical, or hormonal stimuli are transformed into a specific biological effect. Due to its property of reducing the permeability of blood vessel walls, calcium acts anti-inflammatory, anti-edematous, and anti-allergic.
The calcium carbonate contained in the CALPEROS preparations helps to cover the daily demand for calcium, reduces calcium loss from the bone system in women during the peri- and postmenopausal period, as well as in all people in old age. It prevents the occurrence of bone changes in the course of chronic kidney failure. It has a soothing effect on allergic reactions on the skin and mucous membranes.
Indications for use are:
- states of increased demand for calcium: period of intense growth in children and adolescents, as well as during pregnancy and lactation;
- improper nutrition with calcium-poor products;
- disturbances in calcium reabsorption from renal tubules;
- reduced calcium levels in the blood with elevated phosphorus levels in patients with chronic kidney failure undergoing dialysis and prevention of increased neuromuscular excitability;
- prophylactically in the prevention and supplementally in the comprehensive treatment of osteoporosis;
- states after long-term immobilization and the period of convalescence after bone fractures;
- supportively in the treatment of colds and allergic diseases.
2. Important information before taking CALPEROS
When not to take CALPEROS:
- with increased calcium levels in the blood and excessive excretion of calcium in the urine, e.g. in hyperthyroidism, parathyroidism, overdose of vitamin D, decalcifying tumors such as multiple myeloma and tumors metastasizing to bone, in severe untreated kidney failure;
- in kidney stones;
- while being treated with cardiac glycosides;
- in severe hypercalciuria (urine with an excessive amount of excreted calcium).
Warnings and precautions
In the case of chronic kidney failure, it is necessary to control calcium and phosphorus levels in the blood during the use of the medicine.
When using high doses, especially with concurrent use of vitamin D preparations, the risk of elevated calcium levels in the blood with subsequent kidney damage cannot be excluded, so in such patients, it is necessary to control calcium levels in blood serum and kidney function.
Patients treated with cardiac glycosides should consult a doctor before using calcium preparations, as the concurrent use of both medicines may enhance the effect of glycosides on the heart and cause a risk of rhythm disturbances.
During treatment with high doses, especially when taking vitamin D, thiazide diuretics, and (or) calcium-containing medicines or food products (such as milk), there is a risk of hypercalcemia (too high calcium levels in the blood) with subsequent kidney function disorder or milk-alkali syndrome. This risk also applies to pregnant women taking high doses of calcium and patients with impaired kidney function. In these patients, it is necessary to control calcium levels in serum and monitor kidney function.
Taking CALPEROS with food and drink
It is recommended to take the medicine during a meal.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should consult a doctor or pharmacist before taking this medicine.
Pregnancy
During pregnancy, the demand for calcium increases. When using therapeutic doses, no risk to the fetus has been demonstrated.
Breastfeeding
During breastfeeding, the demand for calcium increases. When using therapeutic doses, no risk to the infant has been demonstrated.
Driving and using machines
The medicine does not affect the ability to drive and use machines.
CALPEROS and other medicines
Thiazide diuretics increase calcium reabsorption, reduce the amount of calcium ions excreted in the urine, and create a risk of elevated calcium levels in the blood. In cases of concurrent use, it is necessary to control calcium levels in blood serum.
Concurrently administered systemic corticosteroids reduce calcium absorption and may require an increase in its dose.
Orally administered calcium salts reduce the absorption of tetracycline antibiotics and fluorine compounds from the gastrointestinal tract. These medicines should be administered at an interval of 2 hours.
Calcium compounds may also cause reduced absorption of quinolones, some cephalosporin antibiotics, and iron preparations.
Calcium preparations may enhance the effect and thus increase the toxicity of cardiac glycosides. Therefore, during concurrent use of these medicines, it is necessary to control heart function (electrocardiogram) and calcium levels in the blood.
Bisphosphonates or sodium fluoride should be administered at least 3 hours before taking calcium, due to reduced absorption from the gastrointestinal tract in the case of concurrent use.
During concurrent use of vitamin D or its derivatives in doses above 400 IU/day, calcium absorption from the gastrointestinal tract increases significantly, and hypercalcemia may occur.
During combined treatment with vitamin D and CALPEROS, it is necessary to systematically check calcium levels.
The medicine weakens the effect of verapamil and other calcium channel blockers.
Oxalic acid (found in large quantities in spinach and rhubarb) and phytic acid (found in whole grains) may reduce calcium absorption due to the formation of insoluble calcium salts. Patients should not take calcium preparations within 2 hours of consuming foods with high oxalic acid or phytic acid content.
Thiazide diuretics may increase the risk of hypercalcemia (too high calcium levels in the blood).
CALPEROS contains indigo carmine
The medicine may cause allergic reactions.
3. How to take CALPEROS
This medicine should always be taken exactly as described in this patient leaflet or as advised by your doctor or pharmacist. If you are unsure, you should consult a doctor or pharmacist.
The dose is usually determined based on the daily demand, which is as follows:
| Age category | Amount in mg (in terms of elemental calcium) |
| Adolescents and adults Pregnant and breastfeeding women Postmenopausal women not using hormone replacement therapy (HRT) Postmenopausal women using HRT |
|
| All over 65 years old | 1500 |
Usually, the following dosing is used:
CALPEROS 500: 1 to 2 hard capsules (from 200 mg to 400 mg of calcium) 2 to 3 times a day;
CALPEROS 1000: 1 hard capsule (400 mg of calcium) 1 to 3 times a day.
You should not take more than 1200 mg of calcium ions per day, i.e. no more than 6 hard capsules of CALPEROS 500 or 3 hard capsules of CALPEROS 1000.
Use in children and adolescents
Children over 7 years old and adolescents:
1 hard capsule of CALPEROS 500 (200 mg of calcium) up to 3 times a day.
It is recommended to take the medicine during a meal.
Taking a higher dose of CALPEROS than recommended
There are no reports of cases of acute poisoning with the medicine.
Overdosing on the medicine, especially in patients taking higher-than-therapeutic doses of vitamin D or its derivatives, may lead to elevated calcium levels in the blood. The following may occur: loss of appetite, excessive thirst, nausea, vomiting, constipation, muscle weakness, fatigue, impaired consciousness, polyuria, bone pain, kidney calcification, kidney stones, and in severe cases, cardiac arrhythmias.
Milk-alkali syndrome: it may lead to metastatic calcification.
Treatment of overdose: Calcium administration should be discontinued. Thiazide diuretics, lithium, vitamin A, and cardiac glycosides should not be administered. You should consult a doctor. The doctor will perform gastric lavage, hydrate the patient, and depending on the severity of the overdose, will use one or more medicines (loop diuretics, bisphosphonates, calcitonin, corticosteroids). The levels of electrolytes in the blood, kidney function, and urine excretion will be monitored, and in severe cases, heart function will also be monitored.
Missing a dose of CALPEROS:
The next dose should be taken at the scheduled time.
You should not take a double dose to make up for a missed dose.
4. Possible side effects
