allergic rhinitis
"As a nurse on a busy unit, I can not afford to be drowsy nor work effectively with intense ear and eye itchiness. At times, I would even get wheezy and have problems with my breathing. None of the meds worked and they all made me extremely drowsy. My new family doctor recommended this med, saying 'even fighter pilots can take this'. That was in UK, But in Canada, the highest dosage one can get is 120 mg, that's my one complaint about the med."
