Vitamins with mineral supplements such as iron

Taking Disodium Etidronate Tablets with food and drink
Dairy products and other foods containing calcium can stop your Disodium Etidronate Tablets from being absorbed
properly and if they are not absorbed, they cannot work. For this reason, you should not eat or drink anything but
plain water at least two hours before and two hours after taking your Disodium Etidronate Tablets (i.e. in the middle of
a four hour fast).
How to take Disodium Etidronate Tablets
You should always take this medicine exactly as prescribed by your doctor. Do not take more than the doctor told
you to. Read and follow the instructions on the pharmacist’s label. If you are not sure about anything please ask
your doctor or pharmacist.
Your doctor will tell you how many Disodium Etidronate Tablets to take and when to take them. The amount depends
on your weight and illness. The usual dose to begin with is approximately 5mg a day for each kilogram of your weight.
The tablets should be swallowed with plain water. They should not be taken with milk or other drinks.
How long can you take your Disodium Etidronate Tablets for? If you are taking 5mg or 10mg of disodium
etidronate for each kilogram of your weight, you can take the tablets for up to six months. If you are taking more than
10mg for each kilogram of your weight, you must stop after three months. After three months have elapsed your
doctor may want to put you onto another course of tablets if your condition has flared up again.

Some people with Paget’s disease get new or worse bone pains when beginning their treatment. When therapy
continues the pain resolves in some patients but persists in others. Paget’s patients are also more likely to get broken
