Why Some People Can't Stop Coughing

Understanding Refractory Chronic Cough: What You Need to Know

Have you ever faced a cough that simply refuses to subside?

While most coughs resolve independently, some persist for an unacceptable length of time—weeks, months, or even years. This condition is known as refractory chronic cough (RCC), and it is a significant issue that demands attention in the medical community, especially among specialists in ear, nose, and throat (ENT) care.

In this blog post, we will clearly outline what RCC is, why it occurs, and the most promising treatments available to those suffering from relentless coughing.

What is Refractory Chronic Cough?

A chronic cough is defined as one that lasts longer than eight weeks in adults. For many individuals, it is associated with conditions such as asthma, allergies, acid reflux, or certain medications. However, there are instances where the cough continues even after these underlying causes have been effectively addressed.

This persistent and unexplained coughing is referred to as refractory chronic cough (RCC), which impacts as many as 46% of patients referred to specialists. RCC is not just a nuisance; it can severely disrupt breathing, interfere with daily activities, degrade sleep quality, and hinder social interactions.

It is critical for patients to seek appropriate evaluation and treatment for this distressing condition.

Why Does RCC Happen?

Coughing is a natural reflex that helps clear irritants from our airways. However, in RCC, this reflex becomes overly sensitive, causing a person to cough even when there’s no real need to. Researchers believe that both the nerves in the throat and the brain’s response to cough signals play a role in this hypersensitivity. Factors such as airway inflammation, nerve dysfunction, and central sensitization (similar to chronic pain conditions) can contribute to RCC. Additionally, exposure to pollutants, infections, or prior respiratory illnesses can make the airway more susceptible to developing RCC.

Symptoms and Impact of RCC

People with RCC often experience persistent coughing fits triggered by talking, laughing, exposure to certain smells, or temperature changes. The condition can lead to complications such as voice strain, throat pain, headaches, sleep disturbances, and even urinary incontinence due to the repetitive pressure from coughing. The social impact can also be significant, as people may avoid public places due to embarrassment or discomfort caused by their persistent cough.

New Advances in RCC Treatment

Neuromodulators – Medications like amitriptyline and gabapentin help calm overactive nerves that trigger chronic coughing. Studies show that these drugs can significantly reduce symptoms in many patients. However, they may cause side effects such as drowsiness and dizziness, so careful dosage adjustments are needed.
Superior Laryngeal Nerve (SLN) Block – This involves injecting a local anesthetic and steroid near a key nerve in the throat. It has shown promising results in reducing cough severity and frequency, with some patients experiencing relief lasting several months.
Behavioral Cough Suppression Therapy (BCST) – Speech therapists teach patients techniques to control their cough reflex, including breathing exercises, vocal hygiene, and habit reversal strategies. Many people experience lasting improvement after therapy. This approach is particularly beneficial because it does not involve medication, making it a safer option for many patients.
Capsaicin Therapy – Surprisingly, exposure to capsaicin (the compound that makes chili peppers spicy) in controlled doses can help desensitize the cough reflex over time. This method is still being studied, but early results suggest it may be effective in reducing cough hypersensitivity.
Laryngopharyngeal Reflux (LPR) Management – Since acid reflux can contribute to RCC, new treatments like alginate therapy (which forms a protective barrier in the stomach) are being explored alongside traditional acid-reducing medications. Lifestyle changes, such as dietary modifications and avoiding late-night meals, can also help manage reflux-related cough.
P2X3 Antagonists – A new class of medications targeting the P2X3 receptor, which is involved in the cough reflex, is being studied. Early trials have shown that these drugs may help reduce RCC symptoms, providing another potential treatment avenue.

What This Means for You

The good news is that doctors are finding better ways to treat RCC. Here are some of the latest approaches:

If you or someone you know has a chronic cough that doesn’t improve with standard treatments, it’s important to see a specialist. ENT doctors and pulmonologists (chest physicians) now have a growing range of options to help manage RCC. The key is to undergo a thorough evaluation to rule out underlying conditions and explore the best treatment plan tailored to individual needs.

With ongoing research, treatment for refractory chronic cough is becoming more effective, improving the quality of life for many patients. By spreading awareness about RCC, we can help those affected find the relief they need.

What this leaflet tells you This leaflet explains what to expect after the Epley (canalith repositioning) manoeuvre for posterior-canal BPPV, what you should and shouldn’t do, and when to seek help. 1. Quick summary — what the Epley did The manoeuvre moves tiny particles (otoconia) out of the balance canal of your inner ear and back into a place where they don’t cause spinning (vertigo).

Why Does My Child Have a Lump in Their Neck? A Parent’s Guide to Swollen Glands Discovering a lump in your child’s neck can be unsettling. You may notice it while washing their hair, fastening a school shirt or cuddling them at bedtime. Sometimes your child finds it first and says there is a small “ball” under the skin. One of the first questions parents understandably ask is: “Should I be worried?” Fortunately, the majority of neck lumps in children have a benign explanation , and swollen lymph nodes associated with infections are particularly common. NICE states that reactive cervical lymphadenopathy is the most likely cause of a neck lump in children. However, not every neck lump is simply a swollen gland. Its position, size, duration, whether it is painful and whether your child has other symptoms all matter.

Something Stuck Up Child’s Nose? What Parents Should Do | London & Essex ENT

Something Stuck Up My Child’s Nose? A Parent’s Guide to Nasal Foreign Bodies Young children explore the world with extraordinary curiosity. Unfortunately, that curiosity sometimes involves putting things in places they do not belong. Beads, peas, bits of toys, paper, foam, seeds and small pieces of food can all end up inside a child’s nose. Sometimes a parent actually sees it happen. At other times nobody notices, and the first clue appears days later when the child develops a blocked nostril, an unpleasant smell or discharge from only one side of the nose. A nasal foreign body is the medical term for an object that has become lodged inside the nose. Most can be removed safely, but how parents respond matters . Repeated attempts with tweezers, fingers or other instruments can push an object deeper or injure the nasal lining. There is also one particularly important exception that every parent should know about: a button battery in the nose requires urgent hospital assessme...

Endoscopic Transcanal Cholesterol Granuloma Surgery | London & Essex

Endoscopic Transcanal Cholesterol Granuloma Surgery: Advanced Minimally Invasive Ear Care A persistent feeling of fullness in one ear, fluctuating hearing loss, or a deep, dull earache can easily be mistaken for a standard Eustachian tube dysfunction or stubborn middle ear fluid. However, when these symptoms persist despite routine medical treatment, a closer clinical examination may reveal a dark, bluish discolouration glowing behind the eardrum. In many cases, this distinct visual sign points to a Cholesterol Granuloma —an inflammatory, fluid-filled cystic lesion packed with cholesterol crystals. While hearing the term "granuloma" can cause immediate anxiety, these lesions are non-cancerous, benign formations. Historically, accessing and draining a cholesterol granuloma required large incisions behind the ear and extensive bone removal (a mastoidectomy). Today, modern surgical advancements allow skilled otologists to access and drain these lesions using minimally invasive...
