What Zoledronate-DRLA 4 is used for

  • Zoledronate-DRLA 4 is used to lower the amount of calcium in the blood when it becomes too high, as may happen in some forms of cancer. Some cancers can speed up normal changes in bone so that the amount of calcium released from the bones into the blood is increased. It belongs to a group of medicines called bisphosphonates, which strongly bind to bone. These medicines slow down the rate of bone change and help to restore the amount of calcium in the blood to normal.
  • Zoledronate-DRLA 4 is also used to slow down the spread of cancers in bone, helping to prevent changes to the bones that may cause them to weaken.

It is used in people with advanced cancer of the bone marrow (called multiple myeloma) and other advanced cancers that have spread to the bone. This medicine is used in addition to other standard cancer treatments.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another purpose.

Zoledronate-DRLA 4 is only available with a doctor’s prescription. It is not addictive.

There is not enough information to recommend the use of this medicine in children.

Before you have Zoledronate-DRLA 4

When you must not have it

Do not have Zoledronate-DRLA 4 if you have ever had an allergic reaction to:

  • zoledronic acid (the active ingredient in Zoledronate-DRLA 4) or to any of the other ingredients listed at the end of this leaflet
  • any other bisphosphonate medicine

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

If you are not sure whether you are allergic to other bisphosphonate medicines, talk to your doctor. Other bisphosphonate medicines can cause breathing difficulties in people with asthma who are allergic to aspirin. It is not known whether it can have this effect.

Do not have Zoledronate-DRLA 4 if you are pregnant. There is no information on the use of this medicine in pregnancy.

Do not breast-feed while you are having treatment with Zoledronate-DRLA 4. It is not known if the active ingredient, zoledronic acid, passes into the breast milk and could affect your baby.

If you are being treated with zoledronic acid, you should not be treated with Aclasta concomitantly.

Do not have Zoledronate-DRLA 4 after the expiry date printed on the label or if the packaging is torn or shows signs of tampering. In that case, return the medicine to your pharmacist.

Before you start to have it

Tell your doctor if:

  • you have a kidney or liver problem
  • you have a heart condition
  • you have asthma and are also allergic to aspirin
  • you have had surgery on your thyroid
  • you take any other biphosphonates
  • you had or have pain in the teeth, gums or jaw, swelling or numbness of the jaw or a “heavy jaw feeling” or loosening of a tooth or any other oral issues
  • you had or have joint stiffness, aches and pains and difficulty in movement (especially of the hip or thigh) or pain around the external ear canal
  • you take medication that may lower calcium levels in your blood and you may require calcium with Vitamin D supplements.

It is advisable to have a dental check-up before starting on Zoledronate-DRLA 4 and regular dental check- ups while on it.

Tell your dentist you may be receiving Zoledronate-DRLA 4.

Tell your doctor if you need to have any dental treatment or dental surgery. If you are undergoing dental treatment or will undergo dental surgery, tell your dentist that you are being treated with Zoledronate-DRLA 4.

A dental condition called jaw osteonecrosis has been reported in some patients being treated with Zoledronate-DRLA 4 or with other drugs in the same class as Zoledronate-DRLA 4. You may need to have dental treatments completed before starting it.

Ensure sufficient intake of fluid (water) prior to infusions as directed by your doctor as this will help prevent dehydration.

Your doctor may want to take special precautions if you have any of the above conditions.

Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines and Zoledronate-DRLA 4 may interfere with each other. These include:

  • medicines that may have side effects on your kidneys
  • aminoglycoside medicines, used to treat severe infections. The combination of aminoglycoside and bisphosphonate medicines may cause the level of calcium in the blood to become too low.
  • anti-angiogenic medicines as part of your cancer treatment. The combination of these medicines and bisphosphonate medicines may increase the risk of bone damage in the jaw (osteonecrosis)
  • Aclasta or any other bisphosphonates, such as Actonel, Fosamax
  • loop diuretics, medicines used to treat high blood pressure or oedema
  • calcitonin (a type of medicine used to treat post-menopausal osteoporosis and high calcium levels).

You may need to take different amounts of these medicines or you may need to take different medicines. Your doctor and pharmacist have more information.

If you have not told your doctor about any of these things, tell him/her before you have Zoledronate-DRLA 4.

Practice good dental hygiene. Your routine dental hygiene should include:
