Hi doctor,

I am a 39 year old female. My eosinophil count increase during when the season changes. From the past month, I am having a persistent cough, which is not allowing me to talk. Phlegm is also present. I have taken two bottles of cough syrup Zeet, Sensiclav 625, Montek LC, Rinifol, twice a day for five days, and Mucus cough syrup. By the time I finished taking the medicines, my cough had almost disappeared. But it returned after stopping the medicines. So, I got a blood test done, in which, my erythrocyte count was 5.38, hemoglobin was 13.9, PCV was 43.2, MCV was 80.3, neutrophils were 59.1, eosinophils were 6.1, lymphocytes were 26.8, monocytes were 7.3, and basophils were 0.7. I am taking Banocide forte from the past 10 days, but still, I did not get any relief. I am allergic to dust, and I have a dandruff problem. Please advise.



Welcome to

  • Not to worry, it is something called as hypereosinophilia, which is caused because of infective sources in the body. It can also occur because you are allergic to dust and pollens.
  • I would suggest taking syrup Tossex (combination of Chlorpheniramine and Codeine) two teaspoons, four times a day before meals and tablet Prednisone 5 mg ones a day, early morning before breakfast only for three days. Consult your specialist doctor, discuss with him or her and start taking the medicines after their consent.
  • Your symptoms should improve. Also, continue Banocide forte (Diethylcarbamazine) for three days more.

Thank you and get well soon.

Thank you doctor,

Will these medicines or cough syrup cause sleepiness? As I am a working lady, it will be difficult to work if I am sleepy.



Welcome back to

  • Absolutely not, you can work and do all your routine. I would request you to stay away from dust, pollens, and all things that cause allergy.

Thank you.
