What is Alendronate/Colecalciferol Weekly?

This medication is a tablet that contains two active ingredients, alendronate (commonly known as alendronate) and colecalciferol, also known as vitamin D3.

What is Alendronate?

Alendronate belongs to a group of non-hormonal medications called bisphosphonates. Alendronate prevents bone loss that occurs in women after they enter menopause, and helps to rebuild bone. It reduces the risk of fractures of the spine and hip.

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 correctly from food if it contains sufficient vitamin D, which occurs in very few foods. The main source of vitamin D is the production in the skin, through exposure to sunlight. As we age, our skin produces less vitamin D. A deficiency in vitamin D can lead to bone loss and osteoporosis, and in severe cases can cause muscle weakness that can lead to falls and increase the risk of fractures.

Why is this medication used?

Your doctor has prescribed this medication to treat your osteoporosis and because you are at risk of having a vitamin D deficiency. This medication reduces the risk of fractures of the spine and hip in women after menopause.

What is Osteoporosis?

Osteoporosis causes wear and fragility of the bones. It is common in women after menopause. In 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 the bones become more fragile. The earlier a woman reaches menopause, the greater her risk of osteoporosis.

Initially, osteoporosis does not present symptoms. However, if left untreated, it can cause bone fractures. Although these are usually painful, spinal fractures can go unnoticed until they cause loss of height. Weakened bones can break during normal daily activities, such as standing up or 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 back (widow's hump) and loss of mobility.

How can Osteoporosis be treated?

In addition to your treatment with this medication, your doctor may suggest that you make lifestyle changes to help slow down your disease, such as:

Stopping smokingSmoking appears to increase the rate of bone loss and, therefore, may increase your risk of bone fractures.

ExerciseAs muscles and bones need exercise to stay strong and healthy, consult your doctor before starting any exercise program.

Eating a balanced dietYour doctor may advise you on your diet or whether you should take any dietary supplements.
