Full Consumer Medicine Information (CMI)

This leaflet provides important information about taking FONAT. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about taking FONAT.
Where to find information in this leaflet:

1. Why am I taking FONAT?

FONAT contains the active ingredient alendronate sodium. FONAT belongs to a group of nonhormonal medicines called bisphosphonates.
FONAT is used to treat osteoporosis. This condition is caused by changes in the way bone is normally maintained.
FONAT works by slowing down the process of old bone being removed, which allows the bone-forming cells time to rebuild normal bone. FONAT not only helps prevent the loss of bone but actually helps to rebuild bone and makes bone less likely to fracture. Thus, FONAT prevents or reverses the progression of osteoporosis.
FONAT starts working on the bone cells immediately, but measurable effects on bone mass may not be seen for several months or more.
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. This balanced process keeps your skeleton healthy and strong. 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.
Osteoporosis
"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.
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.
Ask your doctor if you have any questions about why FONAT has been prescribed for you.
Your doctor may have prescribed FONAT for another reason.
FONAT is not addictive.

2. What should I know before I take FONAT?

Warnings

Do not take FONAT if:

you are allergic to alendronate sodium, or any of the ingredients listed at the end of this leaflet.
Always check the ingredients to make sure you can take this medicine.
you have certain disorders of the food pipe (oesophagus) including those that cause difficulty in swallowing
you are unable to stand or sit upright for at least 30 minutes
your doctor has told you that you currently have low blood calcium
your dentist advises you to consult your doctor first

If you have not told your doctor about any of the above, tell him/ her before you start taking FONAT.
During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?
Irritation of the food pipe (oesophagus)
You should know that in some people, FONAT can irritate or burn the food pipe (also called oesophagus). The chances of this happening should be reduced when you follow the instructions in section 4. How do I take FONAT?.
During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Do not take FONAT if you are pregnant or breastfeeding.
FONAT has not been studied in pregnant or breastfeeding women.
Talk to your doctor if you are pregnant or breastfeeding or plan to become pregnant or breastfeed.

Children

Do not give FONAT to a child.
FONAT has not been studied in children.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines may interfere with FONAT and affect how it works. These include:
antacids, medicines used to treat indigestion
calcium supplements
vitamins
You may need different amounts of your medicines, or you may need to take different medicines.
Therefore, take FONAT at least 30 minutes before taking any of these or other medicines to make sure there is no problem with absorption.
You can take aspirin while you are being treated with FONAT. However, both aspirin and FONAT may increase the chance of stomach upsets.
Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking FONAT.
Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect FONAT.

4. How do I take FONAT?

How much to take

Take FONAT only when prescribed by your doctor.
The usual dose of FONAT is one 70 mg tablet once a week.

When to take FONAT

Choose the day of the week that best fits your schedule. Every week, take one table of FONAT on your chosen day.

How to take FONAT

Take FONAT after getting up for the day. Do not take it at bedtime.
Swallow one tablet whole with a full glass of plain water only.
Do not take any food, medicines or drinks other than plain water with your FONAT. It is important to take FONAT with plain water only, not mineral water.
Food, other drugs, mineral water and other drinks, including fruit juices, coffee and tea, will reduce the effect of FONAT by interfering with the absorption into the body.
Stay upright for at least 30 minutes after swallowing FONAT and do not take any food, medicines or drinks other than plain 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 burn or irritation to your food pipe (oesophagus).
FONAT is effective only if taken when your stomach is empty. Food, drinks other than plain water, and other medicines will lessen the effect of FONAT by interfering with its absorption into the body.
Do not chew or suck on a tablet of FONAT.
Mouth ulcers may occur if the tablet is chewed or dissolved in the mouth.

How long to take FONAT

It is important that you continue taking FONAT for as long as your doctor prescribes.
FONAT 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 FONAT

Skip the tablet you missed and take one tablet the following morning after you remember.
If you take the missed FONAT tablet after you have eaten or had a drink, it may not work as well as it should.
Therefore, it is better to skip the missed tablet and continue with your regular schedule on your chosen day.
If you are not sure about what to do, talk to your doctor or pharmacist.
Do not take two tablets on the same day to make up for the dose that you missed.
If you have trouble remembering to take your FONAT, ask your pharmacist for some hints.

If you take too much FONAT

If you take too many tablets at one time, drink a full glass of milk. Do not induce vomiting. Do not lie down.
If you think that you or anyone else has taken too much FONAT, urgent medical attention maybe needed.
You should immediately:
phone the Poisons Information Centre
(by calling 13 11 26) for advice, or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.

Things that would be helpful for your osteoporosis

Some self-help measures suggested below may help your osteoporosis.
Talk to your doctor or pharmacist about these measures and for more information.
Exercise - can be helpful in building and maintaining strong bones. Regular exercise such as a brisk walk is a good idea. Talk to your doctor before you begin any exercise program.
Diet - eat a balanced diet. You may need to increase the amount of calcium in your diet by eating calcium-rich foods or taking a calcium supplement. Your doctor will advise you.
Smoking - appears to increase the rate at which you lose bone and, therefore, may increase your risk of fracture. Your doctor may ask you to stop smoking or at least cut down.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how FONAT affects you.
There have been side effects reported with alendronate that may affect your ability to drive or operate machinery. Individual responses to alendronate may vary. (See 6. Are there any side effects?)

Drinking alcohol
