If you can’t stop coughing, simple measures like drinking warm fluids, staying hydrated, and using over-the-counter medication can often provide relief.
However, if your cough lasts for more than three weeks, keeps coming back, or is accompanied by symptoms such as coughing up blood, chest pain, or difficulty breathing, you should speak to a healthcare professional. In some cases, an ear, nose and throat specialist can investigate persistent coughs and recommend treatments to address the underlying cause.
Key Points
• Stay hydrated, soothe your throat, and avoid irritants like smoke to help reduce coughing.
• Over-the-counter medicines and home remedies can provide temporary relief depending on the cause.
• See a GP if your cough persists or worsens, and an ENT specialist if it becomes a long-term problem.
What can you do instantly to stop coughing?
If you suddenly develop a coughing fit, there are a few things that may help calm it quickly. Taking slow, controlled breaths through your nose instead of gasping through your mouth can reduce throat irritation. Sipping warm water or a warm drink can also help soothe the throat and loosen mucus.
If your throat feels dry, sucking on a sugar-free lozenge may stimulate saliva production and reduce the urge to cough.
Sitting upright rather than lying flat can also help, particularly if your cough is caused by acid reflux or postnasal drip. If you are in a smoky or dusty environment, moving to fresh air may stop further irritation.
Which home remedies can help with constant coughing?
Many coughs improve with simple home remedies such as staying well hydrated helps to keep mucus thin and easier to clear, while also preventing your throat from becoming dry. Warm drinks such as herbal tea or hot water with honey and lemon may provide temporary relief by coating the throat.
Honey has been shown to reduce coughing in some people over the age of one year, particularly when taken before bed. Gargling with warm salt water can also ease throat irritation if your cough is linked to a sore throat.
Using a humidifier or breathing in steam from a warm shower may help if dry air is making your cough worse. It is also worth avoiding cigarette smoke and other airborne irritants, as these can trigger ongoing coughing.
Around 90% of acute coughs are caused by viral infections, meaning they usually improve without antibiotics. Most viral coughs settle within two to three weeks.
Which over-the-counter medication can help with constant coughing?
The right over-the-counter medication depends on the type of cough you have. Simple pain relief such as paracetamol or ibuprofen can help if your cough is associated with a sore throat, fever or general aches.
Cough syrups may provide temporary relief, although evidence for their effectiveness is mixed. Some products are designed to suppress a dry cough, while others help loosen mucus in a chesty cough. Throat lozenges can also soothe irritation and reduce the urge to cough for a short period.
If your cough is caused by allergies, an antihistamine may help reduce symptoms. If acid reflux is the trigger, pharmacy treatments to reduce stomach acid may also improve your cough.
When should you speak to a healthcare professional if you can’t stop coughing?
Most coughs improve on their own, but some require medical assessment. You should speak to a GP if your cough lasts longer than three weeks, keeps returning, or is interfering with your sleep or daily activities.
You should also seek medical advice if you develop a high fever, cough up blood, experience unexplained weight loss, have persistent shortness of breath, or chest pain. These symptoms may need further investigation.
Each year, cough is one of the most common reasons people visit their GP, accounting for millions of consultations across the UK. While most cases are not serious, a persistent cough should always be assessed to rule out underlying conditions.
When should you see an ENT or throat specialist about your coughing?
If your cough continues despite treatment or no clear cause can be found, your GP may refer you to an ear, nose and throat (ENT) specialist. Persistent coughing can sometimes be linked to problems affecting the throat or voice box rather than the lungs.
An ENT specialist will assess your symptoms, examine your throat and may use a small flexible camera to look at your voice box and upper airway. This can help identify conditions such as chronic throat irritation, postnasal drip, vocal cord problems or laryngopharyngeal reflux, where stomach acid reaches the throat.
A specialist assessment is particularly useful if your cough has lasted for several weeks or months and standard treatments have not worked.
What treatments are available from an ENT specialist?
Treatment for chronic coughing depends on the underlying cause of your cough. If postnasal drip is responsible, nasal sprays or allergy treatment may help. If acid reflux is irritating your throat, medication to reduce stomach acid alongside lifestyle changes may improve symptoms.
For people with voice disorders, voice box irritation or muscle tension affecting the throat, speech and language therapy can help reduce the cough reflex. If an infection or another condition is identified, your specialist will recommend the most appropriate treatment.
In some cases, further investigations may be arranged to ensure there is no more serious underlying condition. The aim is not simply to stop the cough but to treat the cause and reduce the chance of it returning.
Is there anything else you can do to stop coughing?
Looking after your overall health can reduce your risk of developing persistent coughs. Washing your hands regularly helps prevent viral infections, while staying hydrated keeps your airways moist. Avoiding smoking and second-hand smoke is one of the most effective ways to protect your throat and lungs.
If you have allergies or asthma, following your treatment plan can help prevent coughing episodes. Managing acid reflux by avoiding large meals before bed, reducing alcohol intake and maintaining a healthy weight may also reduce throat irritation.
Although most coughs improve with time, a cough that persists, keeps coming back or affects your quality of life should not be ignored. Early assessment can identify the cause and ensure you receive the most appropriate treatment.
