Before using Fortical
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of calcitonin nasal spray in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of calcitonin nasal spray in the elderly. However, elderly patients are more likely to have unwanted side effects (eg, irritation or redness of the nose, stuffy or runny nose), which may require caution in patients receiving calcitonin nasal spray.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Interactions with food/tobacco/alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

This medicine is for use only in the nose. Do not get any of it in your eyes or on your skin. If it does get on these areas, rinse it off with water right away.
Each spray bottle contains 30 doses of the medicine. Keep track of the doses you use and throw away any unused medicine after 30 doses, even if the bottle is not completely empty.
This medicine usually comes with patient instructions. Read the instructions carefully before using this medicine. If you have any questions about using the pump spray, ask your doctor.
To assemble the pump:

To prepare this medicine:
- Before you use a new bottle of calcitonin spray, the spray pump will need to be primed (started). If your pharmacist assembled the unit for you, check to see if it has already been primed by pumping the unit once. If a full spray comes out, the unit has already been primed; if not, you must prime the pump.
- To prime a new bottle, hold the bottle upright and away from you, then pump it several times until you see a faint spray.
- Do not prime the pump again before each daily use.
