Alendronate Sandoz is used to treat osteoporosis including osteoporosis caused by a group of medicines known as corticosteroids.

This condition is caused by changes in the way bone is normally maintained.

Understanding bone

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 20s, 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 postmenopausal 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.

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.

How Alendronate Sandoz works

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 Sandoz not only helps prevent the loss of bone but actually helps to rebuild bone and makes bone less likely to fracture. Thus, Alendronate Sandoz reverses the progression of osteoporosis. Alendronate Sandoz starts working on the bone cells immediately, but measurable effects on bone mass may not be seen for several months or more.

Alendronate Sandoz contains the active ingredient alendronate sodium and belongs to a group of non-hormonal medicines called bisphosphonates.

There is no evidence that this medicine is addictive.

Before you start to take it

Tell your doctor if you have allergies to:

  • any other medicines, especially if they are in the same drug class as Alendronate Sandoz
  • any other substances, including foods, preservatives or dyes.

Tell your doctor if you plan on becoming pregnant or will be breastfeeding while you are taking Alendronate Sandoz.

Tell your doctor if you have or have had any medical conditions, especially the following:

  • kidney disease
  • swallowing or digestive problems, such as ulcers.

Tell your doctor if you are planning to have a course of dental surgery.

If you have not told your doctor about any of the above, tell him/her before you start taking Alendronate Sandoz.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines are likely to interfere with the absorption of Alendronate Sandoz if taken at the same time. These include:

  • antacids, such as Algicon#, Almacarb#, Alu-tab#, Amphojel#, De witt’s# antacid, Eno# powder, Gastrobom#, Gastrogel#, Gelusil#, Meracote#, Mucaine#, Mylanta#, Rennie#, Salvital#, Simeco#, Titralac#
  • calcium supplements
  • vitamins.

Therefore, take Alendronate Sandoz at least 30 minutes before taking any of these or other medicines to make sure there is no problem with absorption. Check with your doctor or pharmacist if you are not sure whether you are taking an antacid.

You can take aspirin while you are being treated with Alendronate Sandoz. However both aspirin and Alendronate Sandoz may increase the chance of stomach upsets.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking this medicine.


Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How much to take

Take Alendronate Sandoz only when prescribed by your doctor.

The usual dose of Alendronate Sandoz is one 70 mg tablet once a week.

Choose the day of the week that best fits your schedule. Every week, take one tablet of Alendronate Sandoz on your chosen day.

When and how to take it

Take Alendronate Sandoz after getting up for the day. Do not take it at bedtime.

Swallow one tablet with a full glass of plain water. It is important to take Alendronate Sandoz with plain water only, not mineral water. Mineral water and other drinks, including fruit juices, coffee and tea, will reduce the effect of Alendronate Sandoz by interfering with the absorption into the body.

Stay upright for at least 30 minutes after swallowing Alendronate Sandoz 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 your tablet reaches your stomach quickly and help reduce the potential for irritation to your food pipe (oesophagus).

Alendronate Sandoz 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 Sandoz by interfering with its absorption into the body.

Do not chew or suck on a tablet of Alendronate Sandoz. Mouth ulcers may occur if the tablet is chewed or dissolved in the mouth.

How long to take Alendronate Sandoz

It is important that you continue taking your medicine for as long as your doctor prescribes. Alendronate Sandoz can only treat your osteoporosis, by helping prevent further loss of bone and continuing to rebuild bone, if you take it every week.

If you forget to take it

If you miss a tablet, take one tablet on the morning after you remember.

Do not take two tablets on the same day.

Return to taking one tablet once a week, as originally scheduled on your chosen day.

If you are not sure about what to do, talk to your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Alendronate Sandoz. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

If you take too many tablets at one time, drink a full glass of milk. Do not induce vomiting. Do not lie down.


Things you must do

If you develop difficulty or pain upon swallowing, chest pain, or new or worsening heartburn, stop taking Alendronate Sandoz and call your doctor.
