The name of your medicine is APO-Alendronate Once Weekly. It contains the active ingredient, alendronate (as alendronate sodium).
It is used to treat osteoporosis.
Bone is living, growing tissue. Throughout life, our bodies are breaking down old bone and rebuilding new bone in a continuous cycle.
Until our late 20's, while bones are still developing, we gain bone by building more than we lose. From then until about age 35 the process is usually in balance, so that the amount of bone lost is about equal to the amount that is replaced.
After about age 35 this balance is disturbed, with bone loss occurring at a slightly faster rate than it can be replaced. In women, after menopause, hormonal changes cause bone loss at an even faster rate.
When bone loss is excessive, bones can become thinner and weaker, and therefore are more likely to break.
"Osteo" means bone, and "porosis" means something that has holes in it, like a sponge.
Therefore, osteoporosis is a disease which causes bones to become more porous, gradually making them weaker, more brittle and likely to break.
Osteoporosis is common in post-menopausal women. The menopause occurs when the ovaries virtually stop producing the female hormone, oestrogen, or are removed (which may occur, for example, at the time of a hysterectomy). At this time, bone is removed faster than it is formed, so bone loss occurs and bones become weaker. The earlier a woman reaches the menopause, the greater the risk of osteoporosis.
Osteoporosis also occurs in men but is less common than in women.
Osteoporosis can also occur in people receiving corticosteroid medicines. If taken in high doses or for a long period of time, corticosteroid medicines can cause bone to be removed faster than it is formed. This causes loss of bone and therefore, bones become weaker and are more likely to break.
Maintaining bone mass and preventing further bone loss are important to keep your skeleton healthy.
Early on, osteoporosis usually has no symptoms. However, if left untreated it can result in broken bones, also called fractures. Although fractures usually cause pain, fractures of the bones of the spine may go unnoticed until they cause height loss.
Fractures may occur during normal, everyday activity, such as lifting, or from minor injury that would not ordinarily fracture normal bone. Fractures usually occur at the hip, spine, or wrist and can lead not only to pain, but also to considerable deformity and disability, such as stooped posture from curvature of the spine, and loss of mobility.
Alendronate belongs to a group of medicines called bisphosphonates.
In osteoporosis, it works by slowing down the process of old bone being removed, which allows the bone-forming cells time to rebuild normal bone.
Alendronate not only helps prevent the loss of bone but actually helps to rebuild bone and makes bone less likely to fracture. Thus, alendronate prevents or reverses the progression of osteoporosis.
Alendronate starts working on the bone cells immediately, but measurable effects on bone mass may not be seen for several months or more.

Therefore, take alendronate at least 30 minutes before taking any of these or other medicines to make sure there is no problem with absorption.
You may take aspirin while you are being treated with alendronate. However, both aspirin and alendronate may increase the chance of stomach upsets.
Other medicines not listed above may also interact with alendronate.
Follow carefully all directions given to you by your doctor or pharmacist. Their instructions may be different to the information in this leaflet.
Your doctor or pharmacist will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
The usual dose of this medicine is one 70 mg tablet once a week.
Do not stop taking your medicine or change your dosage without first checking with your doctor.
Swallow one tablet whole with a full glass of plain water only.
It is important to take alendronate with plain water only, not mineral water. Mineral water and other drinks, including fruit juices, coffee and tea, will reduce the effect of alendronate by interfering with its absorption into the body.
Do not crush, chew or suck on a tablet of alendronate.
Mouth ulcers or irritation to your mouth or food pipe (oesophagus) may occur if the tablet is crushed, or chewed or dissolved in the mouth.
Stay upright for at least 30 minutes after swallowing the tablet and do not take any food, medicines or drinks other than plain tap water during this time.
Do not lie down immediately after swallowing it.
It is important to stay upright (sitting, standing or walking around) for at least 30 minutes after swallowing your tablet. It is also very important to stay upright until after you have eaten your first food of the day. These actions will help make sure the tablet reaches your stomach quickly and help reduce the potential for irritation to your food pipe (oesophagus).
Choose a day of the week that best fits your schedule. Every week take one tablet on your chosen day.
Take alendronate immediately after getting up for the day. Do not take it at bedtime, or before you get up in the morning.
Alendronate is effective only if taken when your stomach is empty. Food, drinks other than plain water, and other medicines will lessen the effect of alendronate by interfering with its absorption into the body.
Continue taking your medicine for as long as your doctor tells you.
Alendronate can only prevent or treat your osteoporosis, by helping prevent further loss of bone and continuing to rebuild bone, if you take it every week.
Make sure you have enough to last over weekends and holidays.
If you miss a tablet take one tablet on the morning after you remember.
Do not take two tablets on the same day.
This may increase the chance of you getting an unwanted side effect.
Return to taking one tablet once a week, as originally scheduled on your chosen day.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
