WHAT RISEDRONATE 
WINTHROP IS USED FOR 
Risedronate Winthrop is used to treat 
bone disease and belongs to a group of 
medicines called bisphosphonates. 
Risedronate Winthrop works directly 
on your bones to make them stronger 
and therefore less likely to break or 
fracture. 
Risedronate Winthrop 5mg daily, 
35mg Once-a-Week and 150mg Once-
a-Month tablets are used to treat: 
  osteoporosis (brittle or fragile 
bones that may fracture easily) 
  osteoporosis caused by taking 
steroids  
Risedronate Winthrop 30mg tablets are 
used to treat: 
  Paget's disease of the bone.  
These conditions are caused by 
changes in the way bone is normally

_UNDERSTANDING BONE _
Bone is a living tissue consisting of 
calcium and other minerals.  
Throughout life, old bone is constantly 
broken down and replaced with new 
bone.  After the age of 35, bone loss 
may occur faster than your body can 
replace it. If you lose too much bone 
then they become weaker and are more 
likely to break. 
_OSTEOPOROSIS _
Osteoporosis (brittle bone disease) is a 
disease that causes bones to become 
weaker. Weak bones break (fracture)
