is a long acting drug that is mostly used in managing asthma
and chronic obstructive pulmonary disease. It is marketed worldwide under the brand names Foradil and Oxis.
Formoterol when inhaled works in relaxing the muscles in the airway by diffusing molecules in the plasma
membrane of the lung
cells. It has been found to be more potent and works a lot faster than Salmeterol
. In the latter part of 2005, Formoterol’s effectiveness was put in question as FDA released an advisory regarding its possible relationship with the worsening of symptoms. However, that did not stop Formoterol users from enjoying the benefits of the medicine. In most cases, it is used in combination with inhaled steroids.
Before using Formoterol, you must first consult your doctor if you are safe with it. An allergy
to this medicine and to other drugs is an important detail to note since it can lead to serious conditions. You must also tell your doctor if you are already using a medicine of the same kind. Salmeterol used solely or in combination with other medicines should not be used alongside Formoterol because drug interactions may occur. Your doctor would tell you which medicine you should use and which medicine you should discard in this case. Your doctor must also be duly informed about your use of other medicines apart from Salmeterol. You must also tell him if you have had experiences of irregular heartbeat
, seizure, high blood pressure
, or thyroid disease. Pregnancy and lactation must also be put on the list of your doctor’s concerns.
Like most asthma medications, Formoterol is administered through an inhaler. It comes in a powder filled capsule that is transferred to a special inhaler. Be extra cautious in handling your inhaler. You must keep it clean at all times and free of any foreign bit. For treatment of asthma and COPD
, Formoterol is usually prescribed to be used every 12 hours. To enjoy the full benefits of this medicine, make sure that you follow strictly whatever your doctor tells you to do. Make it clear with your doctor when you can take your other inhaled medicines if you are using them alongside Formoterol.
Note that Formoterol is a long-acting drug. It can prevent asthma attacks from happening but not stop one that is already occurring. Ask your doctor about a different, short-acting medicine that can help you through an attack.
Formoterol may cause side effects, like most medicines available. Those side effects may be mild or severe depending on how your body reacts to the medicine. Episodes of nervousness, headache
, dry mouth
, muscle cramps, and stomach
pain are but normal. However, persistence of such symptoms may need your doctor’s insights as they are supposed to go away after a while. More serious and severe side effects include breathing difficulty, severe chest pain
, lightheadedness, and fainting. Existence of such symptoms would require an immediate medical attention. To ensure your safety with this medicine, work closely with your doctor. Any difference in your condition whether it is for better or for worse must be noted and duly acted upon by a qualified physician.
