1. what calcium gluconate 10 % w/v injection bp is and what it is used for

Calcium Gluconate 10 % w/v Injection BP is a solution for the supplementation of calcium.

It is used for the supply of calcium in patients with abnormally low blood calcium levels (hypocalcaemia) and presenting with acute symptoms such as impaired skin sensations (numbness, itching, burning), convulsive muscular rigidity (tetany), cramps in the hands and feet, colic, muscle weakness, confusion, possibly culminating in convulsions and cardiac symptoms (e.g. irregular heartbeat and even acute heart failure).

2. what you need to know before you use calcium gluconate 10 % w/v injection bp

Do not use Calcium Gluconate 10 % w/v Injection BP

• if you are allergic to calcium gluconate or any of the other ingredients of this medicine (listed in section 6)
• if you have elevated blood calcium levels (e.g. in patients with overactive parathyroid glands, elevated vitamin D levels in the blood, tumour diseases with bone decomposition, impaired kidney function, osteoporosis due to a lack of mobility, sarcoidosis and so-called milk-alkali syndrome)
• in the case of excessive excretion of calcium in the urine
• in the case of poisoning with digitalis medicines (a kind of heart medicine)
• during treatment with digitalis medicines unless you have an extremely low blood calcium level with life-threatening symptoms, which can only be treated by an immediate injection of calcium.
• the antibiotic ceftriaxone should not be used in premature neonates and neonates (< 28 days of age) if they are receiving (or are expected to receive) calcium-containing products which are administered into a vein.

Warnings and precautions

Talk to your doctor before using Calcium Gluconate 10 % w/v Injection BP.

If you are taking digitalis preparations on a regular basis and, as an exception, you urgently require a calcium injection (see above), your doctor will monitor your heart function extremely carefully. The monitoring will ensure, that any worsening of your heart function, e.g. severe arrhythmias (irregular heartbeat), can be treated immediately.

Your doctor will consider very carefully whether this medicine is suitable for you if you suffer from:

• deposition of calcium in the kidneys (nephrocalcinosis)
• heart diseases ______ sarcoidosis,

In these cases you should only be given calcium injections if these are B absolutely essential. This also applies if you receive adrenaline (see “Other medicines and Calcium Gluconate 10 % w/v Injection BP”) or are elderly.

Impaired kidney function (kidney impairment) can be accompanied by increased blood calcium levels and overactive parathyroid glands. If you are suffering from kidney impairment, you should only receive calcium injections if these are absolutely essential. Your calcium and phosphate balance must, however, be monitored.

Your doctor will take special care if you are receiving the antibiotic ceftriaxone. He will not administer it to you simultaneously with calcium gluconate even via different infusion line or different infusion sites.

Calcium should be injected slowly in order to prevent, where possible, widening of the blood vessels or impaired cardiac function.

Your heart rate or ECG should be monitored when this medicine is injected into a vein (intravenous injection).

During calcium salt treatment, you will be carefully monitored to ensure a normal calcium balance (calcium intake versus calcium excretion) and to prevent any chalky deposits in the tissue. Blood calcium levels and the quantities of calcium excreted in the urine will be monitored especially when calciumis injected at high doses.

Calcium is insoluble in fatty tissue and may lead to inflammatory reactions followed by abscess formation, hardening of the tissue and tissue destruction (necrosis) if accidentally injected into these areas. If the solution is inadvertently injected beside a blood vessel or not deep enough into a muscle, this can result in local tissue irritation, possibly followed by peeling of the skin or even necrosis (see section 4). Your doctor will ensure that no solution drains into tissue around the blood vessel and will carefully observe the site of injection.

High doses of vitamin D should be avoided.

Children and adolescents

In children (< 18 years) Calcium Gluconate 10 % w/v Injection BP should only be injected into veins, not into a muscle (intramuscular).

Other medicines and Calcium Gluconate 10 % w/v Injection BP

Tell your doctor if you are taking or have recently taken any other medicines.

The effect of heart medicines like digoxin and other digitalis medicines can be increased by calcium up to the point of digitalis poisoning. Therefore, if you are receiving treatment with digitalis medicines, you will only be given an intravenous calcium injection for the treatment of severe, immediately life-threatening symptoms of a very low blood calcium level.

Administration of calcium together with adrenaline after heart surgery weakens the effects of adrenaline on the heart and circulation. Calcium and magnesium mutually inhibit their effects.

Calcium can reduce the effects of certain medicines used to regulate heart function (calcium antagonists).

Administration of certain medicines increasing the urine formation and output (thiazide diuretics) together with calcium can lead to excessively high blood calcium levels (hypercalcaemia), as these medicinal products reduce the excretion of calcium via the kidneys.

Administration of calcium simultaneously with ceftriaxone will lead to agglomeration.

Pregnancy and breast-feeding

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

Pregnancy

Calcium passes through the placenta into the circulation of the foetus and reaches higher levels in the foetal blood than in the mother’s blood.

Pregnant women should, therefore, only receive calcium injections if absolutely essential. The dose must then be carefully calculated and calcium levels in the blood regularly monitored in order to avoid excessive calcium levels in the blood, which could be harmful to the foetus.

Breast-feeding

Calcium is excreted into breast milk. Your doctor will keep this in mind when administering calcium to you when you are breast-feeding your infant.

Driving and using machines

This medicine has no influence on the ability to drive and use machines.

3. how to use calcium gluconate 10 % w/v injection bp

Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.

The recommended dose will selected by your doctor in order to raise your blood calcium level / your child’s blood calcium level to normal values.

Adults

The usual starting dose is 10 ml, i.e. one ampoule of Calcium Gluconate 10 % w/v Injection BP. If required, the dose may be repeated. Following doses will be adjusted according to your actual blood calcium level.

Use in infants, toddlers, children and adolescents

The doctor will decide on the dosage and method of administration depending on the blood calcium level and the severity of the symptoms. In the case of mild symptoms affecting the nerves and muscles, preference will be given to oral calcium preparations.

The following table gives usual initial dosage values for guidance:

In the case of exceptionally low blood calcium levels in neonates and infants with, for instance, impaired cardiac function, higher starting doses may be required in order to quickly raise the blood calcium levels (up to 2 ml per kg body weight).

Calcium administration can be repeated, if required. The concentration of the following doses will depend on the existing blood calcium level. Following intravenous therapy treatment with oral calcium preparations may be necessary, e.g. in cases of vitamin D deficiency.

Elderly patients

Certain disorders that are sometimes associated with advanced age, such as impaired kidney function and undernourishment (malnutri- _____

tion) may affect the tolerance of calcium gluconate. Therefore, a lower dose must be selected.

Method of administration

Calcium Gluconate 10 % w/v Injection BP will be given to you as an injection slowly into a vein or deep into a large muscle. It should be given to you in a lying position and in particular your heart function should be carefully monitored during the injection.

Due to the risk of local tissue irritation, injections into a muscle (intramuscular injection) should only be made if intravenous injection is not feasible. Your doctor will carefully ensure that the intramuscular injections are administered sufficiently deep, preferably into the large buttock muscle.

The rate of intravenous infusion or injection should be sufficiently slow.

Infants, toddlers, children and adolescents

For intravenous (into a vein) administration as a slow injection or slow intravenous infusion (venous drip), both after dilution.

In children, this medicine should not be injected into a muscle or under the skin.

If you receive more Calcium Gluconate 10 % w/v Injection BP than you should

Symptoms of a high blood calcium level (hypercalcaemia) include: loss of appetite, feeling sick, being sick (vomiting), constipation, belly ache, passing large quantities of urine, increased thirst, fluid loss, muscle weakness, deposition of calcium in the kidneys, drowsiness, confusion, high blood pressure (hypertension) and, in severe cases, irregular heartbeat, up to the point of cardiac arrest and loss of consciousness.

Symptoms of high blood calcium level (hypercalcaemia) and chalky taste, hot flushes and a drop in blood pressure can occur if the intravenous injection is made too rapidly.

Treatment is aimed at lowering the elevated high blood calcium levels.

Your doctor will decide on the treatment to be given. It may include administration of fluids or specific medication to lower the blood calcium level. In severe cases dialysis may become necessary.

If you have any further questions on the use of this medicine, ask your doctor.

4. possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

The frequency of side effects is expressed as follows:

Uncommon: affects 1 to 10 users in 1,000

Rare: affects 1 to 10 users in 10,000

Very rare: affects less than 1 user in 10,000

Not known: frequency cannot be estimated based on the available data.

Side effects on the heart, circulation or other body functions may appear as symptoms of an excessively high blood calcium level after overdosing or too rapid injection into a vein. The presence and frequency of such symptoms depend directly on the speed of injection and the dose administered.

The following side effects may be serious. If any of the following side effects occur tell your doctor immediately, he will stop giving you this medicine:

Not known (Frequency cannot be estimated from the available data):

• slow or irregular heartbeat
• drop in blood pressure (hypotension)
• circulatory collapse (possibly fatal)

B|BRAUN

Rarely (affects 1 to 10 users in 10, 000):

Severe, and in some cases, fatal, adverse reactions have been reported in pre-term and full-term neonates (aged <28 days) who had been treated with intravenous ceftriaxone and calcium. Precipitations of ceftriaxone-calcium salt have been observed in lung and kidneys post-mortem.

Other side effects include:

• Not known (Frequency cannot be estimated from the available data): widening of blood vessels,
• hot flushes, mainly after the injection has been administered too rapidly.
• feeling sick or being sick (vomiting)
• sensation of heat
• sweating
• injections into muscles may be accompanied by pain and redness
• If the injection is not given deep enough into a muscle, the solution may penetrate the fatty tissue, possibly resulting in inflammation, hardening and destruction (necrosis) of the tissue.
• It is been reported that following leaking of the solution from a vein into the surrounding tissue calcium deposition in the soft tissue may occur. It may be followed by peeling and destruction of the skin.
• Redness of the skin and a feeling of burn or pain during intravenous injection may indicate an inadvertent injection beside the blood vessel, which could result in the destruction of the tissue.
