What Fonat is used for
Fonat is used to treat osteoporosis.
This condition is caused by changes in the way bone is normally maintained.
How does Fonat work?
Fonat belongs to a group of non-hormonal medicines called bisphosphonates.
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.
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.
"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
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
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.

Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any
that you get without a prescription from a pharmacy, supermarket or health food shop.
Some medicines are likely to interfere with the absorption of Fonat if taken at the
same time. These include:
antacids, medicines used to treat indigestion
These medicines may be affected by Fonat or may affect how well it works. 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.
Check with your doctor or pharmacist if you are not sure whether you are taking any
of these medicines.
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.

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.
How to take it
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 tap 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
Stay upright for at least 30 minutes after swallowing Fonat 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).
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.
When to take it
Choose the day of the week that best fits your schedule. Every week, take one table
of Fonat on your chosen day.
How long to take it for
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 it
Skip the dose you missed and take your next dose the following morning.
If you take the forgotten tablet after you have eaten or had a drink, Fonat will not
work as well as it should.
Therefore, it is better to skip the dose that you missed.
If you are not sure about what to do, talk to your doctor or pharmacist.
Do not take a double dose 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 (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13
11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you
think that you or anyone else may have taken too much Fonat. Do this even if there
are no signs of discomfort or poisoning.
If you take too many tablets at one time, drink a full glass of milk. Do not induce
vomiting. Do not lie down.
