What DRONALEN PLUS is used for
DRONALEN PLUS is used to treat osteoporosis and to provide additional vitamin D.
Osteoporosis is caused by changes in the way bone is normally maintained. Vitamin D is an essential nutrient required for
calcium absorption and healthy bones.
Bone is a 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
"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.
What should I know about vitamin D?
Vitamin D is an essential nutrient, required for calcium absorption and healthy bones. The main source is through exposure
to summer sunlight, which makes vitamin D in our skin. Clothing or sun block can prevent enough sunlight from getting through.
In addition, as people age, their skin becomes less able to make vitamin D. Very few foods are natural sources of vitamin
Too little vitamin D leads to inadequate calcium absorption and low phosphate-minerals that make bones strong. Even if you
are eating a diet rich in calcium or taking a calcium supplement, your body cannot absorb calcium properly unless you have
enough vitamin D. Too little vitamin D may lead to bone loss and osteoporosis. Severe vitamin D deficiency may cause muscle
weakness which can lead to falls and a higher risk of fracture.
How does DRONALEN PLUS work?
The alendronate in DRONALEN PLUS 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 make bone less likely to fracture. Thus, DRONALEN PLUS reverses the progression of osteoporosis. DRONALEN PLUS starts
working on the bone cells immediately, but measurable effects on bone mass may not be seen for several months or more.
The alendronate in DRONALEN PLUS belongs to a group of non-hormonal medicines called bisphosphonates.
In addition to alendronate, DRONALEN PLUS also contains vitamin D, an essential nutrient required for calcium absorption and

Taking other medicines
Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from your
pharmacy, supermarket or health food shop.
Some medicines may affect the way other medicines work.
Some medicines are likely to interfere with the absorption of DRONALEN PLUS if taken at the same time. These include:
antacids, medicines used to treat indigestion e.g. Gaviscon, Mylanta
Therefore, take DRONALEN PLUS 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 DRONALEN PLUS. However, both aspirin and DRONALEN PLUS may increase
the chance of stomach upsets.
Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking DRONALEN PLUS.
How to take DRONALEN PLUS
How much to take
Take DRONALEN PLUS only when prescribed by your doctor.
The usual dose of DRONALEN PLUS is one tablet once a week.
Choose the day of the week that best fits your schedule. Every week, take one tablet of DRONALEN PLUS on your chosen day.
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.
When and how to take it
Take DRONALEN PLUS after getting up for the day and before taking your first food, beverage or other medication. Do not take
it at bedtime.
Swallow one tablet whole with a full glass of plain water [not mineral water, not coffee or tea, not juice]. Do not take any
food, medicines or drinks other than plain tap water with your DRONALEN PLUS.
It is important to take DRONALEN PLUS with plain water only, not mineral water. Food, other drugs and mineral water and other
drinks, including fruit juices, coffee and tea, will reduce the effect of DRONALEN PLUS by interfering with the absorption
into the body.
Stay upright for at least 30 minutes after swallowing DRONALEN PLUS 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).
DRONALEN PLUS is effective only if taken when your stomach is empty. Food, drinks other than plain water, and other medicines
will lessen the effect of DRONALEN PLUS by interfering with its absorption into the body.
Do not chew or suck on a tablet of DRONALEN PLUS.
Mouth ulcers may occur if the tablet is chewed or dissolved in the mouth.
How long to take it
It is important that you take DRONALEN PLUS for as long as your doctor prescribes it. DRONALEN PLUS can only treat your
osteoporosis, by helping prevent further loss of bone and continuing to rebuild bone, if you take it every week. Since it
is not known how long you should take DRONALEN PLUS, you should discuss the need to stay on this medication with your doctor
periodically to determine if DRONALEN PLUS is still right for you.
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
If you are not sure about what to do, talk to your doctor or pharmacist.

nearest hospital, if you think that you or anyone else may have taken too much DRONALEN PLUS. 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.
