This medication is generally used twice per day and works best if used at the same time each day. It is important to use formoterol exactly as prescribed in order to lessen the chances of developing complications that are sometimes associated with the use of this product.
Some of the more common side effects of formoterol include headaches, dizziness, and nausea. Many patients have also reported side effects such as uncontrollable muscle twitching or stomach pain. Insomnia, runny nose, or a sore throat may also be present in some patients. Many patients are able to tolerate these side effects and do not need to discontinue the medications. Any questions or concerns should be directed to a physician in order to determine whether this type of medication is appropriate for the individual patient or if the doctor needs to prescribe a different type of asthma medication.
Some of the more severe formoterol side effects may include swelling of the throat, face, or legs. This type of swelling, especially involving the face and throat, can be life-threatening and should be considered a medical emergency.
