Drug Description

The inhaler has a protein binding of 96%, and its biological half-life is 5 hours. This term refers to the the time it takes for a substance to lose half of its pharmacologic, physiologic, or radiologic activity.

Use

Serevent is used for the treatment of asthma, exercise-induced bronchospasm and chronic obstructive pulmonary disease. This drug acts by relaxing the airway muscles and facilitate breathing.

How to use this drug?

Never exhale in to the device or wash the mouth piece. Don’t use the retainer with this device. Hold the inhaler in one hand with the mouth piece facing towards you. Click once and breathe through the mouth. Hold your breath for several seconds. Take the inhaler away from the mouth and breathe out slowly. Never use it again even if you don’t feel or taste the medicine, as the repeated use may cause overdose.
If you’re using Serevent for the prevention of bronchospasm, inhale it half an hour before starting any exercise. Controller drugs are used daily and quick-relief medicines are used if the breathing gets harder. Never use it for a long time, if you suffer from thyroid diseases, cardiovascular problems, etc. If the drug isn’t useful, if you exceeded the dose or in case of aggravation of asthma, consult the doctor as soon as possible.
