Quick remedies for a cough include increasing fluid intake to thin out mucus in postnasal drip, taking lozenges because they help suppress the cough reflex somewhat, and drinking tea with honey to soothe the throat, states WebMD. Another remedy is to loosen nose secretions via hot showers.
Humidifiers often help by cycling moisture through the air, according to WebMD. However, they must be cleaned; otherwise, they tend to spread bacteria, fungus and mold in the air. Decongestants and cough suppressants are also two ways to help treat a cough. In cases of thick phlegm, a cough expectorant such as guaifenesin can be helpful. Children three years old and younger should not be given over-the-counter medications.
