There are several things you can do to stop coughing, depending on the underlying cause of your cough. Here are some tips from various sources:

• Drink plenty of fluids, such as water, tea, or broth, to soothe an irritated throat and loosen mucus.
• Have a little honey before bed, as it can help ease a cough. However, do not give honey to children under 12 months.
• Use a cool-mist humidifier or vaporizer to moisten the air, which can help loosen mucus and congestion behind your cough. A steamy shower or bath can also have a similar effect.
• Sip a hot drink, such as chamomile or ginger tea, to ease cold symptoms, including a cough.
• Try over-the-counter cough remedies that contain soothing ingredients such as aloe or menthol. If its hard to get the mucus out, or if it’s thick, look for medicine that says “expectorant” to help you get rid of it. If youre having post-nasal drip with lots of juicy mucous, you may do better with a medicine that dries you up like Sudafed (pseudoephedrine) .
• Use cough drops or hard candy to stop that tickle in the back of your throat. However, do not give cough drops to children younger than 4.
• Stay hydrated and avoid dairy products and alcohol, which can make mucus thicker.
• Avoid inhaled irritants such as dust, perfumes, or pollutants, and dont smoke or be around secondhand smoke.
• Elevate your head at night with an extra pillow to help reduce coughing.
• Use natural remedies such as honey, ginger tea, eucalyptus oil, or mint to soothe throat inflammation and loosen mucus in the lungs. However, it is important to talk to your doctor before using any herbal remedies or natural supplements as some may interact with medications you take.

If your cough is accompanied by other symptoms such as fever, shortness of breath, or foul-smelling phlegm, or if it lasts for a long time or is recurrent, it is important to consult your doctor.
