Some Precautions and Warnings With Formoterol SolutionSome of the warnings and precautions to be aware of with formoterol solution include the following:
- Tell your healthcare provider immediately if you are using formoterol solution more often than usual. Breathing problems can get worse very quickly and can become a medical emergency.
- Rarely, formoterol solution can make bronchospasms (spasms of the airways) worse, which is exactly the opposite of what should happen. Tell your healthcare provider immediately if formoterol solution makes your symptoms worse.
- Formoterol solution is not intended for quick relief of breathing problems (especially in emergency situations). In these instances, a "rescue inhaler" (such as albuterol) should be used.
- Formoterol solution can have a stimulatory effect on the heart and blood pressure, which can result in a fast heart rate (tachycardia), high blood pressure (hypertension), or an irregular heart rhythm (arrhythmia). If you have heart disease or high blood pressure, make sure your healthcare provider is aware of it. He or she may wish to use particular caution if he or she recommends formoterol solution in your case.
- People who have an overactive thyroid (hyperthyroidism), diabetes, or epilepsy should use caution when using formoterol solution, as the medication can make these conditions worse or increase the risk of side effects.

- Formoterol solution can interact with other medications (see Drug Interactions With Formoterol Solution).
