Hi Dear !! Thanks for your query to HCM . Read and reviewed your query and health concerns. You seem to suffer from -Loeffler s Syndrome or AEP(Acute Eosinophilic Pneumonia).Here the Clotrimoxazole does not reduce the dry cough, as the cough is from the eosinophilic bronchospasm. X-ray Chest and Tests for Blood eosinophilia / Stool-Ova /Cyst for- Ascariasis /pinworm infestations/tabpeworms in pork eaters / chronic amoebiasis, need to be done to fix the cause. Possibility of hidden/undetected TB and GERD with acid reflux needs to be ruled out. Occurrence of red dots all over the body of your brother- indicate-Urticarial reaction due to drug reaction to Clotrimoxazole(Sulpha Drug reaction) with reashes all over his body. Do s Suggested- Stop Clotrimoxazole immediately Tab Montelukast(Singulare) 1 x 3 times a day x 1-2 weeks Tab-loratidine- Tab -Banoside fort-100 mg x 3 times a day-x 3 weeks. Tab Dexona- 1 x 2-3 times with tapering of doses over next 10 days time-for control of bronchospasm and drug hypersensitivity. Plenty of fluids to keep airway humid.
