Tablets, chewable tablets, soluble and effervescent tablets and oral liquid

Calcium is a naturally occurring substance which is important for healthy, strong bones. Our bodies usually get sufficient calcium from what we eat. Good sources of calcium in food are milk, hard cheese (such as cheddar or Edam), yoghurt, bread, calcium-fortified soya milk, and some vegetables (spinach and watercress). Sometimes though, our bodies need more calcium than normal - for example, in childhood and during embarazo or whilst lactancia. Also, as we become older our bodies may not absorb as much calcium as they once did. When there is not enough calcium in our diet for our body's needs then a calcium supplement may be useful.

Calcium tablets are also taken by people who have kidney problems. The levels of a substance in the body, called phosphate, can be too high in people with enfermedad renal crónica. Calcium binds to the phosphate and this allows it to be removed, helping to keep the levels normal.

Calcium supplements are also taken alongside other medicines for preventing or treating 'adelgazamiento' de los huesos (osteoporosis). In this case calcium is often combined with vitamin D in chewable or effervescent tablets. More information about this can be found in the separate medicine leaflet called Calcio con colecalciferol.

Calcium supplements are available on prescription, or you can buy them without a prescription at pharmacies.

Before taking calcium supplements

To make sure this is the right treatment for you, before you start taking a calcium supplement it is important that your doctor or pharmacist knows:

  • Si estás embarazada o amamantando. Esto se debe a que, mientras esperas o alimentas a un bebé, solo debes tomar medicamentos por recomendación de un médico.

  • Si tiene problemas renales o ha tenido cálculos renales alguna vez.

  • If you have a condition called sarcoidosis which causes inflammation, particularly in your lungs and lymph system.

  • If you know you have too much calcium in your blood or urine. This can happen with some cancers or with certain medicines for high blood pressure.

  • If you are taking levothyroxine for an underactive thyroid gland (hypothyroidism). This is because calcium affects how well your body absorbs levothyroxine.

  • Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

  • Si alguna vez has tenido una reacción alérgica a un medicamento.

How to take calcium supplements

  • Before you start this treatment, read the manufacturer's printed information leaflet from the pack. The leaflet will give you more information about how to take the supplement, and also a full list of side-effects which you may experience.

  • If you are prescribed calcium by a doctor, you will be told how many tablets to take each day and when to take them. If you have purchased the tablets from a pharmacy, read the label on the preparation carefully to find out how to take them.

  • Some tablets should be swallowed whole without being chewed, other tablets must be chewed before being swallowed, and some need to be dissolved in water. If you are unsure how to take your tablets, ask your pharmacist for advice.

  • Calcium supplements can interfere with the way your body absorbs other medicines so you may need to take these at a different time to your calcium - please ask your pharmacist for advice. Medicines that may be affected include levothyroxine (thyroid hormone) and certain antibiotics.

  • If you forget to take a dose don't worry, just leave out the missed dose and take the next when it is due. Do not take two doses together to make up for a forgotten dose.

Obteniendo el máximo de tu tratamiento

  • Try to eat a balanced diet with plenty of fruit and vegetables and good sources of calcium such as milk and yoghurt.

  • Si tienes programada una operación o cualquier tratamiento dental, informa a la persona que realizará el tratamiento sobre los medicamentos que estás tomando.

  • If you buy any medicines, check with your pharmacist that they are suitable to take with a calcium supplement.
