Yes, what you are describing is very common after an episode of bronchitis, especially during winter. Even though the infection has resolved, the airways often remain hyper-reactive and sensitive for a few weeks. Cold air in the early morning and evening can trigger this residual dry cough. The absence of mucus, fever, breathlessness, or chest pain is reassuring and suggests post-infectious or allergic cough, not an active infection.
You may safely continue an anti-allergic combination like Fexy-M or Allegra-M for another 7–10 days if the cough is bothersome, preferably taken in the evening. These medicines help by reducing airway allergy, post-nasal drip, and cough reflex sensitivity, especially in cold weather. There is no need to restart antibiotics or steroids since she has already improved well and there are no signs of ongoing infection.
In addition, simple supportive measures such as avoiding cold air exposure, using a scarf or mask outdoors, taking warm fluids, and steam inhalation once daily can help settle the cough faster. If the cough persists beyond 2–3 weeks, worsens, or is associated with wheezing, breathlessness, or fever, then a follow-up with the treating doctor would be advisable to assess for asthma-like bronchial hyperreactivity.
At present, continuing Fexy-M or Allegra-M for a few more days is appropriate and safe.
