1. What ALENDROS is and what it is used for What is ALENDROS?

ALENDROS is a tablet containing the active substance alendronic acid (commonly called alendronate) and belongs to a group of non-hormonal medicines called bisphosphonates. ALENDROS 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.

What is ALENDROS used for?

Your doctor has prescribed ALENDROS to treat your osteoporosis. ALENDROS reduces the risk of spine and hip fractures.

ALENDROS is a once weekly treatment.

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.

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.

As well as your treatment with ALENDROS, your doctor may suggest you make changes to your

lifestyle to help your condition, such as:

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

Exercise    Like muscles, bones need exercise to stay strong and healthy. Consult your

doctor before you begin any exercise programme.

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).

2. What you need to know before you take ALENDROS Do not take ALENDROS

•    if you are allergic to alendronic acid or any of the other ingredients of this medicine (listed in section 6)

•    if you have certain problems with your gullet (oesophagus - the tube that connects your mouth with your stomach) such as narrowing or difficulty swallowing

•    if you cannot stand or sit upright for at least 30 minutes

•    if your doctor has told you that you have low blood calcium

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

Warnings and precautions

Talk to your doctor or pharmacist before taking ALENDROS.

It is important to tell your doctor before taking ALENDROS 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).

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

It is important to maintain good oral hygiene when being treated with ALENDROS. 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.

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 ALENDROS. These side effects may worsen if patients continue to take ALENDROS after developing these symptoms.

Children and adolescents

ALENDROS should not be given to children and adolescents less than 18 years of age.

Other medicines and ALENDROS

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

It is likely that calcium supplements, antacids, and some oral medicines will interfere with the absorption of ALENDROS if taken at the same time. Therefore, it is important that you follow the advice given in section 3 How to take ALENDROS.

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

ALENDROS with food and drink

It is likely that food and beverages (including mineral water) will make ALENDROS less effective if taken at the same time. Therefore, it is important that you follow the advice given in section 3 How to take ALENDROS.

Pregnancy and breast-feeding

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

Driving and using machines

There have been side effects (including blurred vision, dizziness and severe bone, muscle or joint pain) reported with ALENDROS that may affect your ability to drive or operate machinery.

Individual responses to ALENDROS may vary (See section 4.)

ALENDROS contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

3. How to take ALENDROS

Always take FOSAMAX exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Take one ALENDROS tablet once a week.

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

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

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

2)    After getting up for the day and before taking any food, drink, or other medicine, swallow your ALENDROS tablet whole with a full glass of water only (not mineral water) (not less than 200 ml).

•    Do not take with mineral water (still or sparkling).

•    Do not take with coffee or tea.

•    Do not take with juice or milk.

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

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.

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

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

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

If you take more ALENDROS 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.

If you forget to take ALENDROS

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 stop taking ALENDROS

It is important that you take ALENDROS for as long as your doctor prescribes the medicine. Since it is not known how long you should take ALENDROS, you should discuss the need to stay on this medicine with your doctor periodically to determine if ALENDROS is still right for you.

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