Expectorant cough mixture
Last reviewed June 2026
Who is this for?
This is a cough mixture that combines three ingredients — ammonium chloride helps loosen thick phlegm in your chest so you can cough it out, sodium citrate helps thin the mucus, and menthol gives a soothing, cooling feeling in your throat.
Stimulates mucus secretion and reduces mucus viscosity through vagal stimulation of bronchial glands, while menthol acts as a topical irritant on respiratory mucosa to promote clearance of airway secretions and provide mild analgesic effects on throat irritation.

Adults should take 2 to 4 teaspoonfuls (10–20 mL) three to four times a day. You can take it with or without food. Shake the bottle well before use. You may find it easier to take if slightly chilled.
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, just skip the missed one and continue as normal. Do not double up to make up for it.
Buy from reputable pharmacies — brands like Pendorex Cough Mixture are well known, so avoid unlabelled or roadside versions. If your cough lasts more than 7 days or you start coughing blood, stop and see a doctor immediately. Do not use this to treat dry cough — it is meant for cough with phlegm.
Avoid taking this with antacids or ulcer drugs containing aluminium or magnesium as they may reduce effectiveness. If you are taking any kidney medication, consult your doctor first. Alcohol may increase the feeling of nausea.
