This medicine may cause your bones to lose calcium, which can lead to osteoporosis (thin or weak bones). This calcium loss could continue the whole time you are receiving this medicine. Your bones should start to rebuild calcium after you stop using this medicine. This is more of a concern if you are a teenager, smoke or drink alcohol regularly, have other bone problems, anorexia nervosa (an eating disorder), a family history of osteoporosis, or use other medicines that also affect your bones (such as steroids or medicine to treat seizures).
You will need to talk with your doctor if you want to use this medicine for more than 2 years. You might need to be tested to make sure your bones are not losing too much calcium.
