Red flags & when to go in person for Postnasal Drip in Children

Audience: pediatric

Postnasal drip occurs when excess mucus from the nose or sinuses drips down the back of the throat, causing discomfort in children. It often leads to coughing, throat clearing, or a sore throat. Many cases are mild and can be managed at home or through telemedicine visits. However, some symptoms may signal a more serious problem requiring in-person medical evaluation. Telemedicine can help assess symptoms, provide advice, and suggest treatments for common causes like allergies or mild infections. Parents should watch for warning signs such as difficulty breathing, high fever, or persistent symptoms lasting more than 10 days. Knowing when to seek in-person care helps ensure children receive timely and appropriate treatment while avoiding unnecessary visits. This guide explains the red flags, what telemedicine can and cannot handle, and how to prepare for and follow up after a telemedicine visit for postnasal drip in children.

Red flags — go in person / ER

• Difficulty breathing or wheezing — seek emergency care immediately.
• High fever over 39°C (102°F) lasting more than 48 hours — arrange in-person evaluation.
• Severe throat pain or difficulty swallowing — see a healthcare provider promptly.

What telemedicine can do

• Assessment of mild to moderate postnasal drip symptoms.
• Advice on home care and over-the-counter treatments.
• Monitoring symptom progression and providing follow-up guidance.

• High or persistent fever requiring physical examination.
• Complications such as suspected bacterial infections needing laboratory tests or imaging.

What is Postnasal Drip in Children?

Postnasal drip happens when extra mucus from the nose or sinuses flows down the back of the throat. In children, this can cause coughing, throat irritation, or a feeling of mucus in the throat. It is often caused by colds, allergies, or mild sinus infections.

When is Telemedicine Appropriate?

Telemedicine can help assess symptoms, review medical history, and suggest treatments for mild cases of postnasal drip. It is useful for monitoring symptoms, recommending over-the-counter remedies, and advising on allergy management without needing to visit a clinic.

FAQs

Can postnasal drip cause a cough in children?

Yes, postnasal drip often causes a cough because mucus dripping down the throat can irritate it and trigger coughing to clear the mucus.

When should I worry about my child's postnasal drip?

You should seek medical care if your child has difficulty breathing, a high fever lasting more than two days, severe throat pain, or if symptoms last longer than 10 days without improvement.

Can allergies cause postnasal drip?

Yes, allergies are a common cause of postnasal drip in children. Managing allergies can often reduce symptoms.

Is it safe to treat my child's postnasal drip at home?

Many mild cases can be managed at home with hydration, nasal saline sprays, and avoiding irritants. However, if symptoms worsen or red flags appear, see a healthcare provider.

Can telemedicine replace in-person visits for postnasal drip?

Telemedicine is helpful for mild cases and follow-up but cannot replace in-person visits when serious symptoms or complications occur.
