Aredronet 90mg Injection is used to treat high levels of a mineral called calcium in people who have cancer. It is also used to treat or prevent weakening of the bones. Using this medicine can reduce your risk of breaking bones. Aredronet 90mg Injection is given by a doctor or nurse. You will not need to do this yourself. How much you are given, and how often, will be decided by your doctor. It may just be a single injection but if you are being treated for bone problems caused by the spread of cancer you may need regular injections. Your doctor will ask you to drink plenty of water before the injection, to avoid getting dehydrated. It may take several days to get the full benefit of this drug. Aredronet 90mg Injection is only part of a program of treatment that may also include changes to your diet and taking calcium and vitamin supplements. The most common side effects include headache, back pain, muscle pain, indigestion, diarrhea, and heartburn. These are usually mild and will disappear after a short time. If they do not go away, tell your doctor. Aredronet 90mg Injection can cause serious kidney problems, especially if you are dehydrated, if you take diuretic medicine (water pills), or if you already have kidney disease. It can also cause low levels of calcium in the blood and pain in the mouth or jaw. These are serious side effects and need urgent medical attention. Tell your doctor straight away. You should not be given this medicine if you are breastfeeding. Before taking it, tell your doctor if you have kidney problems or low calcium levels. Also, let your doctor know what other drugs you are taking. Some of them may affect, or be affected by, this injection, especially medicines used to treat severe infections and medicines used to treat cancer and osteoporosis. You may need frequent medical tests to check your kidney function and mineral levels. Avoid smoking or try to quit as smoking can reduce your bone mineral density, making fractures more likely. Drinking large amounts of alcohol can also cause bone loss and should be avoided.
