Contents of the pack
What isAlendronic Acid/Cholecalciferol Weekly Bluefish?
Alendronic Acid/Cholecalciferol Weekly Bluefish is a tablet that contains two active substances, alendronic acid (commonly called alendronate) and cholecalciferol, known as vitamin D3.
What is alendronate?
Alendronate belongs to a group of non-hormonal medicines called bisphosphonates. Alendronate prevents bone loss that occurs in women after they have entered menopause, and helps to rebuild bone. It reduces the risk of vertebral and hip fractures.
What is vitamin D?
Vitamin D is an essential nutrient, necessary for the absorption of calcium and to maintain healthy bones. The body can only absorb calcium properly from food if it contains sufficient vitamin D, which occurs with very few foods. The main source of vitamin D is production in the skin, through exposure to sunlight. As we age, our skin produces less vitamin D. Vitamin D deficiency can lead to bone loss and osteoporosis, and in severe cases can cause muscle weakness that can result in falls and increase the risk of fractures.
What is Alendronic Acid/Cholecalciferol Weekly Bluefish used for?
Your doctor has prescribed Alendronic Acid/Cholecalciferol Weekly Bluefish to treat your osteoporosis and because you are at risk of having a vitamin D deficiency. Alendronic Acid/Cholecalciferol Weekly Bluefish reduces the risk of vertebral and hip fractures in women, after menopause.
What is osteoporosis?
Osteoporosis is a wasting and fragility of bones. It is common in women after menopause. During menopause, the ovaries stop producing a type of female hormone, estrogen, which helps to maintain a healthy skeleton. As a result, bone loss occurs and bones become more fragile. The earlier a woman reaches menopause, the greater the risk of osteoporosis.
Initially, osteoporosis does not present symptoms. However, if left untreated, it can cause bone fractures. Although these are usually painful, vertebral fractures can go unnoticed until they cause loss of height. Weakened bones can break during normal daily activity, such as when getting up or from minor injuries that would not normally break a normal bone. Bone fractures usually occur in the hip, spine, or wrist, and can cause not only pain but also significant problems such as a hunched posture (dowager's hump) and loss of mobility.
How can osteoporosis be treated?
In addition to your treatment with Alendronic Acid/Cholecalciferol Weekly Bluefish, your doctor may suggest that you make lifestyle changes to help slow down your disease, such as:
Quit smokingSmoking seems to increase the rate of bone loss and, therefore, may increase your risk of bone fractures.
ExerciseLike muscles, bones need exercise to stay strong and healthy. Consult your doctor before starting any exercise program.
