There’s no instant cure for a cough, but several remedies can noticeably reduce coughing within minutes to hours. Most coughs from colds and respiratory infections clear up on their own within three weeks. What you can do right now is calm the irritation, thin the mucus, and create conditions that let your body heal faster.
Honey: The Fastest Home Remedy
Honey is one of the most effective things you can take for a cough, and it works quickly. A clinical trial published in BMJ found that honey improved cough frequency and overall symptom scores in children better than no treatment, and performed at least as well as dextromethorphan, the active ingredient in most over-the-counter cough suppressants. Honey coats and soothes the irritated lining of your throat, and its thick consistency helps suppress the cough reflex almost immediately after swallowing it.
For adults, one to two tablespoons of honey straight or stirred into warm water or tea is a practical dose. For children aged 2 to 5, half a teaspoon is appropriate. Children 6 to 11 can take a full teaspoon, and those 12 and older can take two teaspoons. Never give honey to a child under 1 year old because of the risk of infant botulism.
Saltwater Gargle for Immediate Throat Relief
If your cough is driven by a sore, swollen throat, a saltwater gargle can bring relief within minutes. The warm saline solution draws excess fluid out of inflamed throat tissue, reducing the swelling that triggers your cough reflex. Salt also has natural antimicrobial properties that help lower bacterial levels in the throat.
Mix a quarter to half a teaspoon of table salt into 8 ounces of warm water. Gargle for 15 to 30 seconds, spit it out, and repeat two or three times. You can do this several times throughout the day. It won’t cure the underlying infection, but it reliably takes the edge off throat-driven coughing.
Over-the-Counter Medications
OTC cough products fall into two main categories, and picking the right one depends on the type of cough you have. Suppressants (containing dextromethorphan) work by quieting the cough reflex in your brain. They’re best for dry, hacking coughs that aren’t producing mucus. Expectorants (containing guaifenesin) work differently: they thin out mucus so you can cough it up more easily, which is what you want when your chest feels congested.
Many combination products contain both ingredients. These are widely available under brand names like Mucinex DM and Robitussin. For adults, the typical dose is 10 to 20 mg of dextromethorphan every four hours, with a maximum of 120 mg per day. Follow the label directions for whichever product you choose. Keep in mind that the clinical evidence for dextromethorphan is surprisingly modest. The BMJ trial found it performed no better than honey or even no treatment for nocturnal cough in children, so don’t expect dramatic results.
Humidity and Steam
Dry air irritates already-inflamed airways and makes coughing worse. Adding moisture to your environment helps. A humidifier in your bedroom, particularly at night, can ease coughing and congestion. Cool-mist and warm-mist humidifiers are equally effective because by the time the water vapor reaches your lower airways, it’s the same temperature regardless of how it started.
For a quicker fix, run a hot shower and sit in the steamy bathroom for 10 to 15 minutes. Breathing in the warm, moist air helps loosen mucus in your chest and soothes irritated airways. This is especially useful right before bed.
How to Stop Coughing at Night
Nighttime coughing is often worse than daytime coughing because lying flat allows mucus to pool at the back of your throat, triggering your cough reflex repeatedly. The simplest fix is elevating your head. Add an extra pillow or prop up the head of your bed so gravity keeps drainage moving downward instead of collecting in your throat. Don’t stack pillows so high that your neck is at an awkward angle, though, as that can cause neck pain and disrupt your sleep in a different way.
If you have a dry cough, sleeping on your side rather than your back can reduce irritation. Combining this position change with a dose of honey and a humidifier running in the bedroom gives you the best shot at an uninterrupted night.
Stay Hydrated
Drinking plenty of fluids, particularly warm ones like tea, broth, or warm water with honey and lemon, thins mucus and keeps your throat moist. When mucus is thinner, your body clears it more efficiently, and thick, sticky secretions are less likely to trigger prolonged coughing fits. There’s no magic amount to drink; just sip consistently throughout the day and aim for warm liquids over cold ones when your throat is irritated.
When a Cough Needs Medical Attention
Most coughs resolve within three weeks without any medical treatment. But certain symptoms alongside a cough signal something more serious. Contact a healthcare provider if your cough lasts beyond a few weeks or comes with thick greenish-yellow phlegm, wheezing, fever, shortness of breath, fainting, ankle swelling, or unexplained weight loss.
Seek emergency care if you’re coughing up blood or pink-tinged phlegm, having difficulty breathing or swallowing, experiencing chest pain, or choking and vomiting. For persistent coughs that don’t respond to home remedies or OTC medications, prescription options exist. One common one works by numbing the stretch receptors in your lungs so they stop sending cough signals to your brain. It’s typically reserved for stubborn coughs that resist other treatments.
