I'm sorry to hear your child is experiencing persistent coughing that leads to vomiting. This can be distressing for both the child and the family.

The medications prescribed—Beridil Syrup, Clamp-Kid Forte Suspension, and Lecope M Kid Tablet—include an antibiotic (Clamp-Kid Forte Suspension) that targets bacterial infections. However, if the cough is not improving, it might be due to a viral infection, allergies, or another underlying cause that these medicines do not address.

Here are some important points and recommendations:

• Persistent cough with vomiting in children can sometimes indicate irritation or inflammation in the airways or throat, or other conditions like asthma, whooping cough, or gastroesophageal reflux.
• Since the current treatment has not helped, it is important to revisit the pediatrician or consult a pediatric pulmonologist (lung specialist for children) for a thorough evaluation.
• The doctor may need to perform a physical examination, possibly order chest X-rays or other tests, and review the child's medical history to identify the cause.
• Avoid giving any additional medications without medical advice, as inappropriate use of antibiotics or cough medicines can cause side effects or delay proper treatment.
• Ensure your child stays well-hydrated and rests adequately.
• If your child develops difficulty breathing, high fever, or worsening symptoms, seek emergency care immediately.

Please arrange for a specialist consultation promptly to ensure your child receives the appropriate diagnosis and treatment.To narrow down potential causes, we will need some more information.Please provide the age and gender of your child.
