Most coughs can be stopped or significantly reduced with a combination of home remedies, over-the-counter options, and treating whatever is irritating your airways in the first place. A short-term cough from a cold usually resolves on its own within a few weeks, but the right interventions can make those days far more bearable. A cough that lingers beyond that often signals an underlying cause that needs its own targeted fix.
Honey and Warm Fluids
Honey is one of the most studied natural cough remedies, and it holds up well. A systematic review published in BMJ Evidence-Based Medicine found that honey significantly reduced combined cold symptoms, including cough, compared to placebo. When compared head-to-head with dextromethorphan (the active ingredient in most OTC cough syrups), honey performed roughly the same for cough frequency and severity. That makes it a reasonable first option, especially since it carries almost no side effects for adults.
A spoonful of honey coats the throat and appears to calm the nerve signals that trigger coughing. You can take it straight, stir it into warm water, or mix it with herbal tea. Warm liquids on their own also help by thinning mucus and soothing irritated tissue. One important exception: never give honey to a child under 12 months old due to the risk of botulism.
Keep Your Air Moist (but Not Too Moist)
Dry air irritates already-inflamed airways and makes coughing worse, especially at night. A humidifier in your bedroom can help, but the target range matters. The Mayo Clinic recommends keeping indoor humidity between 30% and 50%. Go higher and you risk condensation that encourages mold, dust mites, and bacteria, all of which can make a cough worse rather than better. Clean your humidifier regularly to prevent buildup inside the tank.
A hot shower serves a similar purpose in the short term. Breathing in the steam loosens mucus and calms irritated airways for temporary relief.
Over-the-Counter Cough Medicine
OTC cough suppressants containing dextromethorphan can reduce the urge to cough by acting on the cough center in the brain. These are most useful for a dry, nonproductive cough that’s keeping you up at night or making it hard to function. If your cough is bringing up mucus, a suppressant can actually work against you by trapping phlegm in your lungs. In that case, an expectorant (guaifenesin) is a better choice because it thins the mucus so you can clear it more easily.
For children, the rules are stricter. The FDA does not recommend OTC cough and cold medicines for children under 2, citing the risk of serious side effects. Manufacturers voluntarily label these products with a cutoff of age 4. For young kids, honey (if over age 1), fluids, and humidity are safer options.
The Huff Cough Technique
If your cough is productive but you’re struggling to actually clear the mucus, a controlled breathing method called the huff cough can help. Cleveland Clinic describes it as similar to the motion of fogging up a mirror: smaller, forceful exhales rather than big, violent coughs that strain your throat and chest.
Here’s how to do it: sit upright with both feet on the floor and your chin tilted slightly up. Take a slow, deep breath until your lungs feel about three-quarters full. Hold for two to three seconds to get air behind the mucus. Then exhale slowly but firmly through an open mouth. Repeat once or twice, then follow with one strong cough to push the loosened mucus out. The key mistake to avoid is gasping in a quick breath right after coughing, which can push mucus back down and trigger uncontrolled coughing fits. Staying well hydrated throughout the day makes this technique more effective because thinner mucus moves more easily.
Post-Nasal Drip
One of the most common reasons for a cough that won’t quit is mucus dripping down the back of your throat from your sinuses. This is called post-nasal drip, or upper airway cough syndrome, and it often gets worse when you lie down, which explains why the cough seems loudest at night.
Antihistamines can help by drying up the excess secretions. Options include older antihistamines like diphenhydramine (Benadryl) and chlorpheniramine (Chlor-Trimeton), which tend to be more effective at drying secretions but cause drowsiness. Newer options like loratadine (Claritin), cetirizine (Zyrtec), and fexofenadine (Allegra) cause less drowsiness and work well when allergies are driving the drip. A saline nasal rinse can also flush irritants and thin mucus without medication.
Acid Reflux and Silent Reflux
Acid reflux is a surprisingly common cough trigger, and many people don’t realize it because they never feel heartburn. A condition called laryngopharyngeal reflux (sometimes called “silent reflux”) sends stomach acid up to the throat, irritating the tissue and triggering a persistent, dry cough. If your cough is worse after meals, when lying down, or accompanied by a scratchy throat or hoarse voice, reflux may be the cause.
Stanford Health Care outlines a three-pronged approach to treating it. The first is diet: cutting back on caffeine, alcohol, chocolate, peppermint, carbonated drinks, citrus, tomatoes, and spicy foods. These either weaken the valve between the stomach and esophagus or directly irritate the throat lining. The second is behavioral changes: eating smaller, more frequent meals, not lying down within three hours of eating, avoiding bending over or exercising for at least two hours after a meal, and propping the head of your bed up about four inches so gravity keeps acid in your stomach overnight.
The third component is medication. Proton pump inhibitors (PPIs) are the most effective option and need to be taken on an empty stomach, ideally 30 minutes before breakfast. The initial treatment course typically lasts at least six months at a twice-daily dose. Antacids like Tums can be used as needed, particularly half an hour after meals. For nighttime symptoms that PPIs don’t fully control, a second type of acid-reducing medication (an H2 blocker) taken before bed can help.
Other Quick Relief Strategies
Several simple measures can reduce coughing in the short term while you address the root cause:
- Elevate your head at night. Propping yourself up with extra pillows or a wedge keeps mucus and acid from pooling in your throat.
- Stay hydrated. Water and warm fluids thin mucus, making it easier to clear and less likely to irritate your airways.
- Suck on lozenges or hard candy. These stimulate saliva production, which soothes and lubricates an irritated throat. Menthol lozenges can also create a mild cooling sensation that temporarily suppresses the cough reflex.
- Avoid known irritants. Cigarette smoke, strong perfumes, cleaning chemicals, and very cold air can all provoke coughing in sensitive airways.
When a Cough Needs Medical Attention
A cough that persists beyond a few weeks, or one that comes with additional symptoms, deserves professional evaluation. The Mayo Clinic flags these as signs to call your doctor: thick greenish-yellow phlegm, wheezing, fever, shortness of breath, fainting, unexplained weight loss, or ankle swelling. Any of these could point to an infection, asthma, or a more serious underlying condition.
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. These symptoms require immediate evaluation regardless of how long the cough has been present.
