After a viral fever or cold, cough and mild cold symptoms can last 2 to 3 weeks, even after antibiotics. It is fine to continue Piriton CS syrup for symptom relief, along with fluids and rest. See a doctor if the cough worsens, lasts beyond 3 weeks, or if fever or breathing difficulty returns.

A cough lasting 7 days is often due to a viral infection, throat irritation, or allergy, and it may take time to settle. Since Piriton and Levolin have not helped much, continue warm fluids, steam inhalation, and rest. Avoid smoke and cold air. See a doctor if the cough worsens, lasts more than 2 to 3 weeks, as you may need a different treatment.

Piriton CS Syrup is usually not recommended for children below 2 years. It is best to consult a paediatrician before giving it to your child, as the doctor can assess the condition and prescribe a safe and suitable medicine based on your child's age and symptoms.
