Fosamax Side Effects

Fosamax is a group of medicines that alter the cycle of bone development and deterioration within the body. Drugs.com explains that Fosamax slows bone loss while increasing bone mass, which may reduce fractures. It is often prescribed for the treatment or prevention of osteoporosis in postmenopausal women. As with any medication, Fosamax has the potential for side effects. It should not be used by those who are nursing, pregnant or who have existing esophageal health issues.
