How Does Fortical Work?

Fortical is a manufactured version of calcitonin, a naturally occurring hormone that helps regulate bone formation and breakdown. It is actually a synthetic version of calcitonin from salmon (known as calcitonin salmon), which is more potent and longer-acting than human calcitonin. It is made using DNA technology; it is not produced using salmon. Fortical works by slowing down the rate at which bone breaks down. Fortical also appears to have some activity as a pain reliever, independent of its effects on bone.
 

When and How to Take Fortical

General considerations for when and how to take Fortical include the following:
 
  • The medication comes as a nasal spray. It is usually taken once a day as one spray, alternating nostrils each time.
     
  • You can take Fortical at any time of the day, but it is a good idea to take it at the same time each day.
     
  • You can take Fortical with or without food.
     
  • The first time you use each bottle of Fortical, you will need to prime the pump by spraying until a fine mist appears.
     
  • Once you assemble a bottle of Fortical, it must be stored in the upright position, not on its side.
     
  • You do not need to try to inhale the medication. It is absorbed into the body from the nasal tissues. Also, you do not need to tip your head back.
     
  • For the medication to work properly, it must be taken as prescribed. Fortical will not work if you stop taking it.
