Calcium can reduce the effect of levothyroxine (used to treat thyroid deficiency). For this reason, levothyroxine should be taken at least four hours before or four hours after Calcichew-D₃ Once Daily.

The effect of quinolone antibiotics may be reduced if taken at the same time as calcium. Take quinolone antibiotics two hours before or six hours after taking Calcichew-D₃ Once Daily.

Calcium salts may decrease the absorption of iron, zinc and strontium ranelate.

Consequently, iron, zinc or strontium ranelate preparations should be taken at least two hours before or after the calcium preparation.

Additional Information

Calcichew-D₃ Once Daily are a combination of calcium and vitamin D designed to keep bones healthy. Calcium is an essential component of bones while vitamin D plays an important role in the absorption of calcium from food.

Requirements for calcium increase with age and, although many people obtain enough calcium from their diet, some people may require a supplement in order that their body has all the calcium it needs to maintain healthy bones. Vitamin D is produced largely from the action of sunlight. Certain foodstuffs do contain vitamin D in reasonable amounts but it is not always possible to obtain all the vitamin D you need from your diet. People who do not get out and about, for instance those who are housebound or people living in nursing and residential homes, may not receive all the vitamin D they need.

People with diets and lifestyles that mean they will obtain less than the recommended intake of calcium and vitamin D are at risk of weakened bones. Prolonged lack of adequate calcium and vitamin D intake can lead to the development of osteoporosis, a condition where bones become weak to a level that minimal trauma (for example, a fall) can result in a fracture, most typically at the hip, spine or wrist.

Calcichew-D₃ Once Daily have been designed to give people whose intakes of calcium and vitamin D are low a boost to the recommended amounts.

Maintaining healthy bones and helping to avoid osteoporosis is an important issue for many people. There are many ways that people can help themselves: regular exercise, a balanced diet with an adequate intake of calcium and vitamin D and, for some people, advice on how to prevent falls which may lead to fracture.

For patients in the UK, the Royal Osteoporosis Society is a national charity dedicated to improving the diagnosis, prevention and treatment of osteoporosis. The Royal Osteoporosis Society offers support to people with osteoporosis and raises awareness of the importance of healthy bones.

If you are concerned about osteoporosis, please contact the Royal Osteoporosis Society, Camerton, Bath BA2 0PJ. Tel: 01761 471 771, or email: info@theros.org.uk.
