Frequently asked questions

How should I take VANTAVO?

One tablet should be taken once a week, choosing a fixed day. The tablet should be swallowed whole with a full glass of tap water (at least 200 ml), in the morning after getting out of bed and on an empty stomach. It is essential not to eat, not to drink anything (except tap water), and not to take other medicines for at least 30 minutes after administration. Additionally, you must remain in an upright position (sitting or standing) for at least 30 minutes after taking the tablet.

When should I not take this medicine?

You must not take the medicine if you are allergic to any of its components, if you have esophageal problems (such as difficulty swallowing or narrowing), if you are unable to sit or stand with an upright torso for at least 30 minutes, or if your doctor has found low calcium levels in your blood.

What are the side effects of VANTAVO?

Common side effects may include heartburn in the upper stomach, difficulty or pain when swallowing, esophageal ulcers, bone, muscle, or joint pain, joint swelling, abdominal pain, constipation, diarrhea, headache, or dizziness. Rarer side effects have also been reported, such as allergic reactions, jaw or dental problems, and possible unusual fractures of the femur.

Can I take other medicines together with this treatment?

It is important to inform your doctor if you are taking other medications. Calcium supplements, antacids, and certain medicines taken at the same time may interfere with absorption. Caution should be exercised with NSAIDs (such as ibuprofen or acetylsalicylic acid) because they can cause digestive problems. Some drugs for weight loss, cholesterol, or seizures may reduce the effectiveness of the vitamin D contained in the product.

What should I do if I forget a dose or take too many?

If you forget the tablet, take it the following morning, but never take two tablets on the same day. In case of accidental ingestion of too many tablets, drink a full glass of milk and contact a doctor immediately, without inducing vomiting and without lying down.

1. What VANTAVO is and what it is used for

What is VANTAVO?
VANTAVO is a tablet containing two active substances, alendronic acid (commonly known as alendronate) and colecalciferol, also known as vitamin D.

What is alendronate?
Alendronate belongs to a group of non-hormonal medicines called bisphosphonates. Alendronate prevents bone tissue loss that occurs in women after menopause and promotes bone rebuilding. Alendronate reduces the risk of vertebral and hip fractures.

What is vitamin D?
Vitamin D is an essential nutrient required for calcium absorption and bone health. The body can adequately absorb calcium from food only if sufficient vitamin D is present. Very few foods contain vitamin D. The main source of vitamin D comes in summer from exposure to sunlight, which triggers vitamin D production in the skin. With aging, the skin produces less vitamin D. Too low levels of vitamin D can cause bone tissue loss and osteoporosis. Severe vitamin D deficiency can cause muscle weakness, which may lead to falls and an increased risk of fractures.

What is VANTAVO used for?
Your doctor has prescribed VANTAVO for the treatment of osteoporosis and to reduce the risk of vitamin D deficiency. This medicine reduces the risk of spinal and hip fractures in postmenopausal women.

What is osteoporosis?
Osteoporosis is a thinning and weakening of the bones. It is common in women after menopause. During menopause, the ovaries stop producing female hormones, the estrogens, which help maintain a woman's healthy skeleton. As a result, bone tissue is lost and 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, spinal bone fractures may go unnoticed until they result in a decrease in height. Fractures can occur during everyday activities such as lifting weights, or from minor trauma that would not normally 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 VANTAVO, your doctor may recommend lifestyle changes to improve the condition, such as:

Smoking cessation: 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 about diet or the possible need for dietary supplements.

2. What you should know before taking VANTAVO

Do not take VANTAVO

  • if you are allergic to alendronic acid, colecalciferol, or 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 are unable to stand or sit upright 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
instructions given.

Warnings and precautions

Talk to your doctor or pharmacist before taking VANTAVO if:

  • you have kidney problems,
  • you have or have recently had difficulty swallowing or gastrointestinal 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),
  • your doctor has told you that you have a problem with mineral absorption in the stomach or intestine (malabsorption syndrome),
  • you have poor dental health, gum disease, are planning a tooth extraction, or do not regularly visit your 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 check-up before starting treatment with
VANTAVO.
It is important to maintain good oral hygiene during treatment with VANTAVO.
You should have regular dental check-ups throughout your treatment and contact your doctor
or dentist if you experience any problems with your mouth or teeth, 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 tap water and/or lie down
within the first 30 minutes after taking VANTAVO. These side effects may worsen if patients continue taking VANTAVO after experiencing these symptoms.

Children and adolescents
VANTAVO must not be given to children and adolescents under 18 years of age.

Other medicines and VANTAVO
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 VANTAVO if taken at the same time.
Therefore, it is important to follow the instructions provided in section 3 and wait at least 30 minutes before taking any other oral medicines or supplements.
Some medicines used for rheumatism or long-term pain, called NSAIDs (e.g. acetylsalicylic acid or ibuprofen), may cause gastrointestinal problems. Therefore, caution should be used when taking these medicines together with VANTAVO.
Some medicines or food additives may prevent the vitamin D in VANTAVO from being absorbed, including artificial fat substitutes, mineral oils, weight-loss medicines such as orlistat, and cholesterol-lowering medicines such as cholestyramine and colestipol. Medicines for seizures (epilepsy) (such as phenytoin or phenobarbital) may reduce the effectiveness of vitamin D. Additional vitamin D supplements may be considered on an individual basis.

VANTAVO with food and drinks
Food and drinks (including mineral water) may reduce the effectiveness of VANTAVO if taken at the same time. Therefore, it is important to follow the instructions in section 3. You must wait at least 30 minutes before consuming any food or drink other than tap water.

Pregnancy and breastfeeding
VANTAVO is intended only for postmenopausal women. Do not take VANTAVO if you are pregnant or suspect you may be pregnant, or if you are breastfeeding.

Driving and using machines
With VANTAVO, side effects have been reported (e.g. blurred vision,
dizziness, and severe bone, muscle, or joint pain) that may impair your ability to drive
or operate machinery (see section 4). If any of these side effects occur, you must not drive until you feel well again.

VANTAVO contains lactose and sucrose.
If your doctor has diagnosed you with an intolerance to certain sugars, please consult them before taking this medicine.

VANTAVO contains sodium.
This medicine contains less than 1 mmol (23 mg) of sodium per tablet, i.e. essentially “sodium-free”.
