The following observations relevant to systemic absorption were made in clinical studies. In one uncontrolled study a statistically significant decrease in responsiveness to metyrapone was noted in 15 adult steroid-independent patients treated with mg of flunisolide per day (the maximum recommended dose) for 3 months. A small but statistically significant drop in eosinophils from % to % of total circulating leucocytes was noted in another study in children who were not taking oral corticosteroids simultaneously. A 5% incidence of menstrual disturbances was reported during open studies, in which there were no control groups for comparison.
Don't ignore a chronic cough — but don't panic just because your cough lingers for more than three or four weeks. Most often, the puzzle can be solved without elaborate tests, and the problem can be corrected with simple treatments. In fact, you may be able to diagnose and treat yourself, especially if postnasal drip or gastroesophageal reflux is the culprit. Even so, your doctor can also help. In most cases, it won't take much more than a stethoscope and a treatment trial or two. But if your cough is accompanied by sputum production, bloody sputum, fever, weight loss, night sweats, breathlessness, undue fatigue, or chest pain, you should consult your doctor without delay. You can expect tests ranging from sputum exams and chest x-rays to pulmonary function tests, CT scans, and bronchoscopies. In most cases, you'll get good news — and you can expect to get a treatment program that will quiet your nagging cough.
