Fortical Side Effects
Back pain, runny or stuffy nose, and other nasal symptoms are the most common side effects of Fortical. These side effects are generally mild and don't require medical attention. However, there are some less common but potentially serious Fortical side effects that should be reported to a healthcare provider right away, including depression, severe or frequent nosebleeds, and allergic reactions.
As with any medicine, side effects are possible with Fortical® (calcitonin salmon nasal spray); however, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Fortical. Your healthcare provider can discuss a more complete list of Fortical side effects with you.)
Calcitonin salmon (the active ingredient in Fortical) has been studied thoroughly in clinical trials, in which a group of people taking the drug have side effects documented and compared to another group not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, the most common side effects of calcitonin salmon nasal spray included:
- Runny or stuffy nose -- in up to 12 percent of people
- Other nasal symptoms (such as nasal redness, crusting, bleeding, or irritation) -- up to 10.6 percent
- Back pain -- up to 5 percent.
Other common side effects (occurring in 1 to 3 percent of people) included:
- Muscle pain
- Indigestion or heartburn
- Constipation or diarrhea
- Bladder infection
- Wearing away of joint cartilage
- Sinus infection
- Upper respiratory tract infection (such as the common cold)
- High blood pressure (hypertension)
- Unusual sensations (such as burning or tingling).
