If you have any further questions on the use of this product, ask your doctor or pharmacist.

If you stop taking FOSAMAX
It is important that you continue taking FOSAMAX for as long as your doctor prescribes the medicine. FOSAMAX can treat your osteoporosis only if you
continue to take the tablets.

If you forget to take FOSAMAX
If you miss a dose, just 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 take more FOSAMAX than you should
If you take too many tablets by mistake, drink a full glass of milk and contact your doctor immediately. Do not make yourself vomit, and do not lie down.

6) After swallowing your FOSAMAX tablet, wait at least 30 minutes before taking your first food, drink, or other medicine of the day, including
antacids, calcium supplements and vitamins. FOSAMAX is effective only if taken when your stomach is empty.

5) If you develop difficulty or pain upon swallowing, chest pain, or new or worsening heartburn, stop taking FOSAMAX and contact your doctor.

4) Do not take FOSAMAX at bedtime or before getting up for the day.

3) Do not lie down — stay fully upright (sitting, standing or walking) — for at least 30 minutes after swallowing the tablet. Do not lie down until after
your first food of the day.

Do not crush or chew the tablet or allow it to dissolve in your mouth.

2) After getting up for the day and before taking any food, drink, or other medicine, swallow your FOSAMAX tablet whole with a full glass of water only
(not mineral water) (not less than 200 ml or 7 fl. oz.).
• Do not take with mineral water (still or sparkling).
• Do not take with coffee or tea.
• Do not take with juice or milk.

It is very important to follow instructions 2), 3), 4) and 5) to help the FOSAMAX tablet reach your stomach quickly and help reduce the chance of irritating your
gullet (oesophagus - the tube that connects your mouth with your stomach).

1) Choose the day of the week that best fits your schedule. Every week, take one FOSAMAX tablet on your chosen day.

Follow these instructions carefully to make sure you will benefit from FOSAMAX.

Take one FOSAMAX tablet once a week.


Important information about some of the ingredients of FOSAMAX
FOSAMAX contains lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this

Driving and using machines
There have been side effects (including blurred vision, dizziness and severe bone, muscle or joint pain) reported with FOSAMAX that may affect your
ability to drive or operate machinery. Individual responses to FOSAMAX may vary (See POSSIBLE SIDE EFFECTS.)

Pregnancy and breast-feeding
FOSAMAX is only intended for use in postmenopausal women. You should not take FOSAMAX if you are or think you may be pregnant, or if you are

Children and adolescents
FOSAMAX should not be given to children and adolescents.

Taking FOSAMAX with food and drink
It is likely that food and beverages (including mineral water) will make FOSAMAX less effective if taken at the same time. Therefore, it is important that
you follow the advice given in section 3. HOW TO TAKE FOSAMAX.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Certain medicines for rheumatism or long-term pain called NSAIDs (e.g. aspirin or ibuprofen) might cause digestive problems. Therefore, caution should
be used when these medicines are taken at the same time as FOSAMAX.

Taking other medicines
It is likely that calcium supplements, antacids, and some oral medicines will interfere with the absorption of FOSAMAX if taken at the same time.
Therefore, it is important that you follow the advice given in section 3. HOW TO TAKE FOSAMAX.

Irritation, inflammation or ulceration of the gullet (oesophagus – the tube that connects your mouth with your stomach) often with symptoms of chest
pain, heartburn, or difficulty or pain upon swallowing may occur, especially if patients do not drink a full glass of water and/or if they lie down less than
30 minutes after taking FOSAMAX. These side effects may worsen if patients continue to take FOSAMAX after developing these symptoms.

It is important to maintain good oral hygiene when being treated with FOSAMAX. You should have routine dental check-ups throughout your treatment
and you should contact your doctor or dentist if you experience any problems with your mouth or teeth such as loose teeth, pain or swelling.

You may be advised to have a dental check-up before starting treatment with FOSAMAX.

Take special care with FOSAMAX
It is important to tell your doctor before taking FOSAMAX if:
• you suffer from kidney problems,
• you have any swallowing or digestive problems,
• your doctor has told you that you have Barrett’s oesophagus (a condition associated with changes in the cells that line the lower oesophagus),
• you have been told you have low blood calcium,
• you have poor dental health, gum disease, a planned dental extraction or you don’t receive routine dental care,
• you have cancer,
• you are undergoing chemotherapy or radiotherapy,
• you are taking corticosteroids (such as prednisone or dexamethasone),
• you are or have been a smoker (as this may increase the risk of dental problems).

If you think any of these apply to you, do not take the tablets. Talk to your doctor first and follow the advice given.

Do not take FOSAMAX
(1) if you are allergic (hypersensitive) to alendronate sodium trihydrate or any of the other ingredients
(2) if you have certain problems with your gullet (oesophagus - the tube that connects your mouth with your stomach) such as narrowing or difficulty
(3) if you cannot stand or sit upright for at least 30 minutes
(4) if your doctor has told you that you have low blood calcium


Eating a balanced diet Your doctor can advise you about your diet or whether you should take any dietary supplements (especially calcium and
Vitamin D).

Smoking appears to increase the rate at which you lose bone and, therefore, may increase your risk of broken bones.

Stopping smoking

As well as your treatment with FOSAMAX, your doctor may suggest you make changes to your lifestyle to help your condition, such as:

How can osteoporosis be treated?
Osteoporosis can be treated and it is never too late to begin treatment. FOSAMAX not only prevents the loss of bone but actually helps to rebuild bone
you may have lost and reduces the risk of bones breaking in the spine and hip.

Early on, osteoporosis usually has no symptoms. If left untreated, however, it can result in broken bones. Although these usually hurt, breaks in the
bones of the spine may go unnoticed until they cause height loss. Broken bones can happen during normal, everyday activity, such as lifting, or from
minor injury that would not generally break normal bone. Broken bones usually occur at the hip, spine, or wrist and can lead not only to pain but also
to considerable problems like stooped posture (‘dowager’s hump’) and loss of mobility.

What is osteoporosis?
Osteoporosis is a thinning and weakening of the bones. It is common in women after the menopause. At the menopause, the ovaries stop producing
the female hormone, oestrogen, which helps to keep a woman’s skeleton healthy. As a result, bone loss occurs and bones become weaker. The earlier a
woman reaches the menopause, the greater the risk of osteoporosis.

FOSAMAX is a once weekly treatment.

What is FOSAMAX used for?
Your doctor has prescribed FOSAMAX to treat your osteoporosis. FOSAMAX reduces the risk of spine and hip fractures.

What is FOSAMAX?
FOSAMAX belongs to a group of non-hormonal medicines called bisphosphonates. FOSAMAX prevents the loss of bone that occurs in women after
they have been through the menopause, and helps to rebuild bone. It reduces the risk of spine and hip fractures.
