Can Bactrim make a child's cough worse?

I am afraid that it will be necessary to consult a doctor. Usually, the administration of an antibiotic alone does not cause the severity of cough, but it may indicate the progression of infection and the need to introduce, for example, inhalation with steroids. Coughing attacks after Bactrim may occur in very rare cases. According to the manufacturer: "The occurrence of pulmonary infiltrates similar to those that occur in the case of eosinophilic or allergic alveolitis. They may be manifested by coughing, shortness of breath (shortness of breath). If similar symptoms occur or worsen unexpectedly, the patient should be reassessed and discontinuation of Bactrim treatment should be considered." Therefore, if the therapy is not effective, and you even see a deterioration in the child's health, you should urgently consult a pediatrician.
