What is in this leaflet
This leaflet answers some common questions about risedronate. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you using this medicine against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may want to read it again.
What this medicine is used for
Risedronate is used to treat osteoporosis, including osteoporosis caused by taking steroids. It is also used to preserve bone mineral density in patients on long term steroid therapy.
Throughout life, old bone is broken down and replaced with new bone. After the age of 35, bone loss may occur faster than your body can replace it. Excessive bone loss causes bones to become thinner and weaker, and therefore more likely to break.
Osteoporosis is a disease that gradually weakens bones. Early osteoporosis may not show symptoms. However, if left untreated, it can result in broken bones. Osteoporosis can also cause back pain, height loss and a curved back.
How it works
Risedronate works by slowing down the process of old bone being removed, which allows the bone-forming cells time to rebuild normal bone. This reverses the progression of osteoporosis by creating stronger bone which is less likely to fracture.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
This medicine is not addictive.
There is not enough information to recommend the use of risedronate in children under the age of 18 years.

Taking other medicines

Some medicines and risedronate may interfere with each other. These include:
- antacids, used to treat indigestion
- other products containing calcium, magnesium, iron or aluminium supplements
These medicines may be affected by risedronate or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

How to take this medicine

How much to take
The usual dose is either:
- one 35 mg tablet weekly on the same day each week; or
- one 75 mg tablet taken on two consecutive days (two tablets in total) each month; or
- one 150 mg tablet monthly on the same date each month.
Choose the day that best fits your schedule.
How to take it
Swallow your tablet whole with a glass of plain water. Do not chew or suck the tablet.

Do not lie down immediately after swallowing it.
Do not take any food, medicines or drinks other than plain water for 30 minutes during this time.
These actions will help make sure the tablet reaches your stomach quickly and helps avoid irritation to your oesophagus.
When to take it
