How Topex Expectorant works

Topex Expectorant is a combination of four medicines: Citric Acid, Diphenhydramine, Ammonium Chloride and Menthol. Citric Acid is a natural substance that helps relieve mild cough. Diphenhydramine is an antiallergic which relieves cough associated with allergies by blocking a chemical messenger, histamine. Ammonium Chloride is an expectorant which works by decreasing the stickiness of mucus (phlegm) and helps in its removal from the airways. Menthol produces a cooling sensation and relieves throat irritation.

Quick tips

  • Topex Expectorant is prescribed to get relief from cough.
  • Drink warm water to help loosen the congestion and lubricate your throat while you are taking this medication.
  • Take exactly as directed by your doctor or on the label. Do not increase the dosage or take for longer than is recommended. Use a proper measuring cup or spoon to measure the dosage.
  • In general, most coughs do not last more than 2 weeks. If your cough does last longer than this then it's better to see your doctor.
  • Inform your doctor if you have a history of stomach ulcers or asthma.
