1. What Alendros is and what it is used for

What Alendros is
Alendros contains the active substance alendronic acid and belongs to a group of
medicines called bisphosphonates, which act on the structure and density
(mineralization) of bones.

What Alendros is used for
Alendros is used to treat a disease that causes bones to become fragile and more likely to break
(osteoporosis) in both men and postmenopausal women.
Alendros is also used in men and women for the treatment and prevention
of osteoporosis caused by a specific class of medicines used to treat inflammation, called glucocorticoids.

What is osteoporosis?
Osteoporosis is a disease that weakens bones, making them more likely to fracture. During
menopause, the ovaries stop producing female hormones, oestrogens, which help maintain a woman’s skeletal health. As a result, bone tissue is lost and bones become more fragile. The risk of osteoporosis is greater the earlier a woman reaches menopause.
Osteoporosis can also occur in men. Glucocorticoids can also cause loss of bone tissue and osteoporosis in both men and women.
In its early stages, osteoporosis usually causes no symptoms. However, if left untreated, fractures may occur. Although fractures are often painful, fractures of the spinal bones may go unnoticed until a decrease in height becomes apparent. Fractures can occur during normal daily activities, such as lifting weights, or following minor trauma that would not normally cause a fracture in healthy bone. Fractures most commonly occur in the hip, spine, or wrist and can be not only painful but may also lead to significant deformity and disability, such as increased curvature of the back (kyphosis) and limitations in movement.

2. What you need to know before taking Alendros

Do not take Alendros

  • if you are allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6)
  • if you have problems with your esophagus (the tube connecting your mouth to your stomach) that delay its emptying, such as narrowing (stenosis) or impaired function (achalasia)
  • if you are unable to remain upright or sitting with your back straight for at least 30 minutes
  • if you have low levels of calcium in your blood (hypocalcemia)
  • if you have severe kidney problems (severe renal insufficiency)
  • if you are pregnant or breastfeeding

If you think any of these apply to you, do not take the tablets. Consult your doctor and follow their instructions.

Warnings and precautions

Talk to your doctor or pharmacist before taking Alendros.

Inform your doctor before starting Alendros:

  • if you have difficulty swallowing (dysphagia), or if you have gastrointestinal problems such as esophageal diseases, inflammation of the stomach (gastritis), or of the first part of the intestine (duodenitis). If you have previously suffered from severe gastric or duodenal diseases such as ulcers, gastric or intestinal bleeding within the past year, or have undergone surgery on the stomach or esophagus, because Alendros may cause irritation and potentially worsen underlying gastrointestinal disease
  • if you have been diagnosed with a condition involving changes in the cells lining the lower part of the esophagus (Barrett's esophagus)
  • if you have cancer
  • if you are undergoing chemotherapy, radiotherapy, or treatment with medicines that inhibit angiogenesis (the development of new blood vessels from pre-existing ones)
  • if you are taking medicines for inflammation (glucocorticoids)
  • if you smoke, as smoking may increase the risk of dental problems

You may be advised to have a dental examination before starting treatment with Alendros.
It is important to maintain good oral hygiene during treatment with Alendros. You should have regular dental check-ups throughout your treatment and contact your doctor or dentist if you experience any mouth or dental problems such as tooth loss, pain, or swelling.
If you are under dental care or need a dental procedure or tooth extraction, inform your dentist that you are taking Alendros.
Stop taking Alendros and contact your doctor immediately if you experience difficulty swallowing (dysphagia), pain when swallowing (odynophagia), chest pain (retrosternal pain), or the onset or worsening of heartburn (pyrosis).
If Alendros is not taken correctly or if you continue taking it after experiencing these symptoms, the risk of serious adverse effects on the esophagus may increase.
It is very important that you understand how to take this medicine correctly (see section 3).
Treatment with Alendros should only be started after your doctor has confirmed that your osteoporosis is due to lack of female hormones (estrogens) and/or age, having ruled out other causes.
Alendros may irritate the mucosa of the upper gastrointestinal tract.
The risk of serious adverse effects on the esophagus appears to be higher in patients who do not take Alendros appropriately or who continue taking it after experiencing symptoms of esophageal irritation. It is important to know that failure to follow certain precautions may increase the risk of esophageal problems.
In patients treated with Alendros, adverse effects on the esophagus have been reported, including irritation (esophagitis), lesions (ulcers and erosions), rarely followed by narrowing or perforation. Some of these adverse effects have been severe and required hospitalization.
In cancer patients taking bisphosphonates, mainly by intravenous route, death of bone tissue in the jaw (osteonecrosis) has been reported, usually associated with tooth extraction or local infection (including osteomyelitis). Many of these patients were also receiving chemotherapy and corticosteroids. Osteonecrosis of the jaw has also been reported in patients with osteoporosis taking oral bisphosphonates.
Bone, joint, and muscle pain have been reported in patients treated with bisphosphonates. Since the medicine has been marketed, these symptoms have rarely been severe or disabling (see section 4). The onset of symptoms has varied from one day to several months after starting treatment. In most patients, discontinuation of treatment led to improvement of symptoms. Following re-administration of the same medicine or another from the same class, some patients experienced recurrence of symptoms.
Unusual femoral fractures have been reported, primarily in patients on long-term treatment with this class of drugs for osteoporosis. These fractures occur spontaneously or after minor trauma, and some patients experience thigh or groin pain.
X-rays often reveal these types of fractures (stress fractures) weeks or months before a complete femoral fracture occurs.
Fractures often occur in both femurs (bilateral fractures); therefore, in patients treated with bisphosphonates who have experienced a femoral fracture, the other femur should also be examined.
Delayed healing of these fractures has also been reported. In patients with suspected femoral fracture, your doctor will assess whether bisphosphonate therapy should be discontinued, weighing the benefits against the risks.
During treatment with this type of medicine, you should report any thigh, hip, or groin pain to your doctor. If you experience such symptoms, you should be evaluated to rule out the presence of a femoral fracture.
Since the medicine has been marketed, rare cases of serious skin reactions have been reported, including skin peeling (Stevens-Johnson syndrome) and skin decomposition (toxic epidermal necrolysis).
Before starting Alendros treatment and periodically thereafter, your doctor may request blood tests to monitor your calcium levels (calcemia). Low calcium levels in the blood (hypocalcemia) must be corrected before starting Alendros treatment (see section 2). Your doctor will monitor your blood calcium levels and symptoms of hypocalcemia during Alendros treatment and will also manage other disorders such as vitamin D deficiency.
During treatment with Alendros, rare cases of low calcium levels (hypocalcemia), occasionally severe, have occurred, particularly in conditions that may predispose to hypocalcemia, such as low parathyroid hormone production (hypoparathyroidism), vitamin D deficiency, and calcium malabsorption, especially in patients taking glucocorticoids, which reduce calcium absorption. Adequate calcium and vitamin D intake is recommended in patients receiving glucocorticoids.

Children and adolescents

Alendros is not recommended for children under 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, including those without a prescription.
Calcium supplements, antacids, and certain oral medicines may interfere with the absorption of Alendros if taken at the same time. At least 30 minutes must pass after taking Alendros before taking any other medicine (see instructions in section 3 “How to take Alendros”).
Some medicines called NSAIDs (e.g., aspirin or ibuprofen), used to treat joint and bone inflammation (rheumatism) or long-term pain, may cause gastrointestinal disturbances. Therefore, caution should be exercised when taking these medicines together with Alendros.

Alendros with food and drink

Food and drink (including mineral water) may reduce the effectiveness of Alendros if taken at the same time. It is therefore important to follow the instructions provided in section 3 “How to take Alendros”.

Pregnancy and breastfeeding

If you are pregnant, suspect you may be pregnant, planning to become pregnant, or breastfeeding, consult your doctor or pharmacist before taking this medicine.
Alendros is indicated only for postmenopausal women.

Driving and using machines

During treatment with Alendros, adverse effects (including blurred vision, dizziness, and severe bone, muscle, or joint pain) have been reported, which may affect your ability to drive or operate machinery. Individual responses to Alendros may vary (see section 4).

Alendros contains lactose

If your doctor has diagnosed you with an intolerance to certain sugars, contact them before taking this medicine.

3. How to take Alendros

Take this medicine exactly as directed by your doctor or pharmacist. If you have any doubts, consult your doctor or pharmacist.
The recommended dose is 1 tablet of 10 mg once daily.
The optimal duration of treatment for osteoporosis with this medicine has not been established.
Your doctor will periodically evaluate the optimal duration of treatment based on the benefits achieved versus the potential risks of Alendros, particularly after 5 or more years of use.
Alendros must be taken at least 30 minutes before any food, drink, or other medicine of the day, and only with tap water. Other beverages (including mineral water), food, and certain medicines may reduce the absorption of Alendros (see section 2).
Alendros is effective only when taken on an empty stomach.
To facilitate gastric release and reduce the risk of irritation/local adverse effects and esophageal damage:

  • take the Alendros tablet in the morning, only after getting up from bed to start the day, with a full glass of tap water (not mineral water, at least 200 ml);
  • swallow the Alendros tablet whole. Do not chew, crush, or allow the tablet to dissolve in the mouth, due to the potential risk of injury to the mouth and pharynx;
  • do not lie down until you have eaten something, and ensure at least 30 minutes have passed after taking the Alendros tablet before lying down;
  • do not take the Alendros tablet at bedtime or before getting up from bed in the morning;
  • do not take Alendros with coffee or tea;
  • do not take Alendros with juices or milk;
  • if you experience difficulty or pain when swallowing, chest pain, or new or worsening heartburn, stop taking Alendros and contact your doctor immediately.

Your doctor may recommend calcium and vitamin D supplements if your dietary intake of these nutrients is inadequate (see section 2).
Use in children and adolescents
Alendros is not recommended for children under 18 years of age.
Use in the elderly
No dose adjustment is necessary in elderly patients.
Use in patients with impaired renal function
No dose adjustment is required in patients with mild to moderate renal impairment (creatinine clearance greater than 35 ml/min). Alendros must not be administered in patients with severe renal impairment (creatinine clearance <35 ml/min), as there is insufficient information available.
If you take more Alendros than you should
If you accidentally take too many tablets, drink a glass of milk or take an antacid and contact your doctor immediately or go to the nearest hospital. Do not induce vomiting and avoid lying down to prevent esophageal irritation.
If you forget to take Alendros
If you forget to take an Alendros tablet, take one tablet the morning after the day you remember.
Do not take a double dose to make up for the missed tablet. Resume taking the tablet daily as previously scheduled. If in doubt, consult your doctor.
If you stop taking Alendros
It is important to continue taking Alendros for as long as prescribed by your doctor. Alendros is effective in treating osteoporosis only if the tablets are taken continuously.
If you have any questions about the use of this medicine, consult your doctor or pharmacist.

1. What ALENDROS is and what it is used for

What is ALENDROS?
ALENDROS is a tablet containing the active substance alendronic acid (commonly known as alendronate) and belongs to a group of non-hormonal medicines called bisphosphonates. ALENDROS prevents the loss of bone tissue that occurs in women after menopause and promotes bone rebuilding. It reduces the risk of vertebral and hip fractures.
What is ALENDROS used for?
Your doctor has prescribed ALENDROS for the treatment of osteoporosis. It reduces the risk of vertebral and hip fractures.
ALENDROS is a treatment to be taken once a week.
What is osteoporosis?
Osteoporosis is the thinning and weakening of bones. It is common in women after menopause. During menopause, the ovaries stop producing the female hormones, estrogens, which help maintain a woman's skeletal health. As a result, bone tissue is lost and the bone becomes weaker. The risk of osteoporosis is greater the earlier a woman reaches menopause.
In its early stages, osteoporosis usually causes no symptoms. However, if left untreated, fractures may occur. Although fractures are usually painful, fractures of the spinal bones may go unnoticed until they result in a decrease in height. Fractures can occur during normal daily activities such as lifting weights, or following minor trauma that would not cause fractures in normal bone. Fractures typically occur in the hip, spine, or wrist and can be not only painful but may also lead to significant deformities and disability, such as curvature of the back (kyphosis) and limitations in movement.
How can osteoporosis be treated?
Along with treatment with ALENDROS, your doctor may recommend lifestyle changes to improve the condition, such as:
Stopping smoking Smoking appears to increase the rate at which bone tissue is lost and therefore may increase the risk of fractures.
Physical exercise Like muscles, bones need physical activity to stay strong and healthy. Consult your doctor before starting any exercise programme.
Balanced diet Your doctor can provide information on diet or the possible need for dietary supplements (especially calcium and vitamin D).

2. What you should know before taking ALENDROS

Do not take ALENDROS

  • if you are allergic to alendronate acid or to any of the other ingredients of this medicine (listed in section 6)
  • if you have certain problems with your oesophagus (the tube connecting your mouth to your stomach), such as narrowing or difficulty swallowing
  • if you cannot stand upright or sit in an upright position for at least 30 minutes
  • if your doctor has told you that you have low levels of calcium in your blood.

If you think any of these apply to you, do not take the tablets. Consult your doctor and follow
the advice given.
Warnings and precautions
Talk to your doctor or pharmacist before taking ALENDROS if:

  • you have kidney problems,
  • you have or have recently had difficulty swallowing or digestive problems,
  • your doctor has told you that you have Barrett's oesophagus (a condition associated with changes in the cells lining the lower part of the oesophagus),
  • you have been told that you have a problem absorbing minerals in your stomach or intestine (malabsorption syndrome),
  • you have been told that you have low levels of calcium in your blood,
  • you have poor dental health, gum disease, are scheduled for a tooth extraction, or do not regularly visit a dentist,
  • you have cancer,
  • you are undergoing chemotherapy or radiotherapy,
  • you are taking angiogenesis inhibitors (such as bevacizumab or thalidomide) used in the treatment of cancer,
  • you are taking corticosteroids (such as prednisone or dexamethasone) used to treat conditions such as asthma, rheumatoid arthritis, and severe allergies,
  • you are or have been a smoker (as this may increase the risk of dental problems).

You may be advised to have a dental examination before starting treatment with ALENDROS.
It is important to maintain good oral hygiene during treatment with ALENDROS. You should
have regular dental check-ups throughout your treatment and contact your doctor or dentist
if you experience any mouth or dental problems such as tooth loss, pain, or swelling.
Irritation, inflammation, or ulceration of the oesophagus (the tube connecting the mouth to the
stomach) may occur, often with symptoms such as chest pain, burning in the upper stomach,
difficulty or pain when swallowing, especially if patients do not drink a full glass of water and/or
lie down during the first 30 minutes after taking ALENDROS.
These side effects may worsen if patients continue taking ALENDROS after experiencing these
symptoms.
Children and adolescents
ALENDROS must not be given to children and adolescents under 18 years of age.
Other medicines and ALENDROS
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any
other medicines.
Calcium supplements, antacids, and certain oral medicines are likely to interfere with the
absorption of ALENDROS if taken at the same time. It is therefore important to follow the
