1. What Ibandronic acid tablets is and what it is used for

Ibandronic acid belongs to a group of medicines called bisphosphonates. It contains the active substance ibandronic acid. Ibandronic acid may reverse bone loss by stopping more loss of bone and increasing bone mass in most women who take it, even though they won’t be able to see or feel a difference. Ibandronic acid may help lower the chances of breaking bones (fractures). This reduction in fractures was shown for the spine but not for the hip.

Ibandronic acid is prescribed to you to treat postmenopausal osteoporosis because you have an increased risk of fractures. Osteoporosis is a thinning and weakening of the bones, which is common in women after the menopause. At the menopause, a woman’s ovaries stop producing the female hormone, oestrogen, which helps to keep her skeleton healthy.

The earlier a woman reaches the menopause, the greater her risk of fractures in osteoporosis.

Other things that can increase the risk of fractures include:

  • not enough calcium and vitamin D in the diet
  • smoking, or drinking too much alcohol
  • not enough walking or other weight-bearing

    exercise

  • a family history of osteoporosis

A healthy lifestyle will also help you to get the most benefit from your treatment. This includes:

  • eating a balanced diet rich in calcium and

    vitamin D

  • walking or any other weight-bearing exercise
  • not smoking; and not drinking too much alcohol.

2. What you need to know before you take Ibandronic acid tablets

Do not take Ibandronic acid tablets

  • If you are allergic to ibandronic acid, or any of

    the other ingredients of this medicine listed in section 6.

  • If you have certain problems with your gullet/

    food pipe (oesophagus) such as narrowing or difficulty swallowing.

  • If you can’t stand or sit upright for at least one

    hour (60 minutes) at a time.

  • If you have, or had in the past low blood

    calcium. Please consult your doctor.

Warnings and precautions

A side effect called osteonecrosis of the jaw (ONJ) (bone damage in the jaw) has been reported very rarely in the post marketing setting in patients receiving ibandronic acid for osteoporosis. ONJ can also occur after stopping treatment.

It is important to try and prevent ONJ developing as it is a painful condition that can be difficult to treat. In order to reduce the risk of developing osteonecrosis of the jaw, there are some precautions you should take.

Atypical fractures of the long bones, such as in the forearm bone (ulna) and the shinbone (tibia), have also been reported in patients receiving long-term treatment with Ibandronate. These fractures occur after minimal, or no trauma and some patients experience pain in the area of the fracture prior to presenting with a completed fracture.

Before receiving treatment, tell your doctor/nurse (health care professional) if:

  • you have any problems with your mouth or teeth

    such as poor dental health, gum disease, or a planned tooth extraction

  • you don’t receive routine dental care or have not

    had a dental check up for a long time

  • you are a smoker (as this may increase the risk

    of dental problems)

  • you have previously been treated with a

    bisphosphonate (used to treat or prevent bone disorders)

  • you are taking medicines called corticosteroids

    (such as prednisolone or dexamethasone)

  • you have cancer

Your doctor may ask you to undergo a dental examination before starting treatment with ibandronic acid.

While being treated, you should maintain good oral hygiene (including regular teeth brushing) and receive routine dental check-ups. If you wear dentures you should make sure these fit properly. If you are under dental treatment or will undergo dental surgery (e.g. tooth extractions), inform your doctor about your dental treatment and tell your dentist that you are being treated with ibandronic acid.

Contact your doctor and dentist immediately if you experience any problems with your mouth or teeth such as loose teeth, pain or swelling, or non-healing of sores or discharge, as these could be signs of osteonecrosis of the jaw.

Some people need to be especially careful while they’re taking ibandronic acid. Talk to your doctor before taking ibandronic acid:

  • If you have any disturbances of mineral

    Previous Pip-Code

    707-5886

    Guides

    • If your kidneys are not functioning normally.
    • If you have any swallowing or digestive problems.

Irritation, inflammation or ulceration of the gullet/ food pipe (oesophagus) often with symptoms of severe pain in the chest, severe pain after swallowing food and/or drink, severe nausea, or vomiting may occur, especially if you do not drink a full glass of water and/or if you lie down within an hour of taking ibandronic acid. If you develop these symptoms, stop taking ibandronic acid and tell your doctor straight away (see section 3).

Children and adolescents

Do not give ibandronic acid to children or adolescents below 18 years.

Other medicines and Ibandronic acid

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

  • Supplements containing calcium, magnesium, iron or aluminium, as they could possibly influence the effects of ibandronic acid.
  • Acetylsalicylic acid and other non-steroidal anti-inflammatory medicines (NSAIDs) (including ibuprofen, diclofenac sodium and naproxen) may irritate the stomach and intestine. Ibandronic acid may also do so. So be especially careful if you take painkillers or anti-inflammatories while you’re taking ibandronic acid.

After swallowing your monthly ibandronic acid tablet, wait for 1 hour before taking any other medication, including indigestion tablets, calcium supplements, or vitamins.

Ibandronic acid with food and drink:

Do not take Ibandronic acid with food. Ibandronic acid is less effective if it’s taken with food. You can drink water but no other drinks

After you have taken Ibandronic acid tablets, please wait for 1 hour before you can have your first food and further drinks. (see 3. How to take Ibandronic acid tablets).

Pregnancy and breast feeding

Ibandronic acid is for use only by postmenopausal women and must not be taken by women who could still have a baby.

Do not take ibandronic acid if you are pregnant or breast feeding.

Ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

You can drive and use machines as it’s expected that ibandronic acid has no or negligible effect on your ability to drive and use machines.

Ibandronic acid tablets contains lactose.

If you have been told by your doctor that you cannot tolerate or digest some sugars (e.g. if you have a galactose intolerance, the Lapp lactase deficiency or have problems with glucose-galactose absorption), talk to your doctor before taking this medicine.

3. How to take Ibandronic acid tablets

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

The usual dose of Ibandronic acid is one tablet once a month.

Taking your monthly tablet

It’s important to follow these instructions carefully. They are designed to help your Ibandronic acid tablet reach your stomach quickly, so it’s less likely to cause irritation.

  • Take one Ibandronic acid 150 mg tablet once a month.
  • Choose one day of the month that will be easy to remember. You can choose either the same date (such as the 1st of each month) or the same day (such as the first Sunday of each month) to take your Ibandronic acid tablet. Choose the date that best fits your routine.
  • Take your Ibandronic acid tablet at least 6 hours after you last had anything to eat or drink except water.
  • Take your Ibandronic acid tablet

    • after you first get up for the day, and
    • before you have anything to eat or drink

      (on an empty stomach)

  • Swallow your tablet with a full glass of water

    (at least 180 ml).

Do not take your tablet with water with a high concentration of calcium, fruit juice or any other drinks. If there is a concern regarding potentially high levels of calcium in the tap water (hard water), it is advised to use bottled water with a low mineral content.

  • Swallow your tablet whole, do not chew it, crush it or let it dissolve in your mouth.
  • For the next hour (60 minutes) after you’ve taken your tablet

    • do not lie down; if you do not

      stay upright (standing or sitting), some of the medicine could leak back into your oesophagus

    • do not eat anything
    • do not drink anything (except

      water if you need it)

    • do not take any other medicines
  • After you’ve waited for an hour, you can have your first food and drink of the day. Once you’ve eaten, it’s OK to lie down if you wish, and to take any other medication you need.

Continuing to take Ibandronic acid tablets

It’s important to keep taking ibandronic acid every month, as long as your doctor prescribes it for you. After 3-5 years of using ibandronic acid, please consult with your doctor whether you should continue to take ibandronic acid.

If you take more Ibandronic acid tablets than you should

If you’ve taken more than one tablet by mistake, drink a full glass of milk and talk to your doctor straight away.

Do not make yourself vomit, and do not lie down — this could cause Ibandronic acid to irritate your oesophagus.

If you forget to take Ibandronic acid tablets

If you forget to take your tablet on the morning of your chosen day, do not take a tablet later in the day. Instead, consult your calendar and find out when your next scheduled dose is.

If you forgot to take your tablet on your chosen day and your next scheduled dose is only 1 to 7 days away.

Never take two Ibandronic acid tablets within the same week.

You should wait until the next scheduled dose is due and take it as normal; then, continue taking one tablet once a month on the scheduled days you’ve marked on your calendar.
