I'm sorry to hear your child has been experiencing a chesty cough with rattling for 20 days. Prolonged cough in a young child can be concerning and may indicate an underlying infection or other respiratory issue that needs careful evaluation.

Here are some important points and recommendations:

• Duration and Symptoms: A cough lasting more than two weeks warrants medical assessment to rule out infections like bronchitis, pneumonia, or other causes such as asthma or allergies.
• Medications Given: Maxtra (likely an antibiotic), Ambrolite (a mucolytic to thin mucus), and Piriton (an antihistamine) are commonly used, but persistent symptoms despite these suggest further evaluation is needed.
• Next Steps: It is important to have your child examined by a pediatrician or a pediatric pulmonologist. They may recommend:
  • A thorough physical examination including listening to the lungs.
  • Possible chest X-ray or other investigations to identify any infection or lung involvement.
  • Review and adjustment of medications based on findings.
• When to Seek Urgent Care: If your child develops difficulty breathing, high fever, persistent vomiting, or appears very unwell, seek emergency care immediately.

Please arrange a consultation with a pediatrician promptly to ensure appropriate diagnosis and treatment. If symptoms worsen or new symptoms develop, do not delay seeking urgent medical attention.To narrow down potential causes, we will need some more information.Please tell me your child's gender.
