What is in this leaflet

This leaflet answers some common questions about alendronate. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you using this medicine against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may want to read it again.

What this medicine is used for

Alendronate is used to treat osteoporosis. It belongs to a group of medicines called bisphosphonates.

Osteoporosis is a disease which causes bones to become more porous, gradually making them weaker, more brittle and likely to break.

Understanding Bone

Bone is living, growing tissue. Throughout life, our bodies are breaking down old bone and rebuilding new bone in a continuous cycle.

How it works

Alendronate works by slowing down the process of old bone being removed, which allows the bone-forming cells time to rebuild normal bone. Alendronate helps prevent the loss of bone and helps to rebuild bone, making bone less likely to break. This helps to prevent or reverse the progression of osteoporosis.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed alendronate for another reason.

This medicine is available only with a doctor’s prescription.

This medicine is not addictive.

There is not enough information to recommend the use of alendronate in children.

Before you take this medicine

Alendronate can irritate or burn your mouth or food pipe (also called the oesophagus). The chances of this happening should be reduced if you follow the instructions for taking alendronate in this leaflet.

When you must not take it

Do not take this medicine if you have an allergy to:

  • alendronate
  • any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue, throat or other parts of the body
  • itching or hives on the skin

Do not take this medicine if you have the following medical conditions:

  • certain disorders of the food pipe (oesophagus)
  • conditions that cause difficulty in swallowing
  • unable to stand or sit upright for at least 30 minutes
  • low blood calcium (hypocalcaemia)

Do not take this medicine if you are pregnant, plan to become pregnant or are breastfeeding. Alendronate has not been studied in pregnant or breast-feeding women.

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

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

  • serious kidney disease
  • swallowing or digestive problems, such as stomach pain, reflux, ulcers, Barrett’s oesophagus
  • low vitamin D levels
  • diabetes
  • alcohol abuse
  • any bone fractures

Tell your doctor if you have any of the following, which may increase your risk of getting jaw bone problems:

  • cancer
  • radiotherapy, chemotherapy treatment
  • taking angiogenesis inhibitors
  • problems with your teeth, mouth or gums
  • anaemia
  • problems with blood clotting
  • infection
  • you are a smoker
  • you are taking steroids
  • you are planning to have any dental procedures such as tooth extraction or other oral surgery
  • you don’t regularly look after your teeth or see a dentist.

If you have not told your doctor about any of the above, tell them before you start taking this medicine.

Taking other medicines

Tell your doctor 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 may interfere with alendronate if taken at the same time. These include:

  • antacids
  • calcium supplements
  • non-steroidal anti-inflammatory drugs (NSAIDs), e.g. ibuprofen.

Take alendronate at least 30 minutes before taking any of these or other oral medicines.

Other medicines not listed above may also interact with alendronate.

How to take this medicine

Follow all directions given to you by your doctor or pharmacist carefully. They may differ to 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

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

How to take it

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).

When to take it

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.

How long to take it for

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 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. 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.

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 of this medicine. 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 or take some antacids. Do not make yourself vomit and do not lie down. If you take too much alendronate, you may have an upset stomach, heartburn, throat or stomach pain or problems swallowing.

While you are taking this medicine

Things you must do

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

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.

Tell your doctor immediately if you develop pain in your hip or thigh. This may be a sign that you have a stress fracture of your hip or upper thigh bone.

Tell your doctor immediately if you break a bone, or you develop bone, muscle or joint pain.

Tell your doctor and dentist if you require a dental procedure, or if you develop toothache, jaw pain, delayed healing or infection.

Tell your doctor if you are going to have surgery.

Keep up good oral hygiene practices by:

  • regularly brushing teeth
  • cleaning between teeth with floss or interdental cleaner
  • eating a balanced diet
  • visiting your dentist regularly

Make sure you receive enough calcium and Vitamin D in your diet.

Your doctor, dietician or pharmacist can tell you what foods you should eat, and whether you should take a supplement.

Things you must not do

Do not give this medicine to anyone else, even if they have the same condition as you.

Do not take your medicine to treat any other complaint unless your doctor tells you to.

Do not stop taking your medicine, or change the dosage, without first checking with your doctor.

Things that would be helpful for your osteoporosis

Talk to your doctor or pharmacist about the following self-help measures for more information:

  • Exercise can help to build and maintain strong bones.
  • Eat a balanced diet, ensuring you have enough calcium and Vitamin D in your diet.
  • Smoking may increase the rate at which you lose bone, increasing your risk of fracture. You may need to stop or cut down on smoking.
  • Drinking alcohol excessively on a regular basis may increase your risk of developing osteoporosis. You may need to cut down on the amount of alcohol you drink.

Things to be careful of

Be careful driving or operating machinery until you know how this medicine affects you. Alendronate can make some people feel giddy or dizzy or have blurred vision.

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