How Ducof LS Syrup works

Ducof LS Syrup is a combination of three medicines: ambroxol, levosalbutamol, and guaifenesin. Ambroxol is a mucolytic that thins and loosens mucus in the airways, making it easier to cough up. Levosalbutamol is a bronchodilator that relaxes the muscles around the airways, helping open them and making breathing easier. Guaifenesin is an expectorant that helps clear mucus from the airways by making it thinner and less sticky, promoting its removal through coughing. Together, these medicines help reduce mucus buildup, ease breathing, and relieve cough associated with mucus.

Quick tips

  • Ducof LS Syrup is used to relieve cough with mucus by thinning and clearing phlegm from the airways.
  • Drink plenty of fluids while taking Ducof LS Syrup, as this helps loosen mucus and improves its effect.
  • Ducof LS Syrup is not meant for dry cough (cough without mucus).
  • Ducof LS Syrup may cause dizziness or sleepiness. Do not drive or operate machinery until you know how it affects you.
  • Stop taking Ducof LS Syrup and contact your doctor if you develop severe palpitations, chest discomfort, tremors, or a very fast heartbeat.
  • Inform your doctor if you have heart disease, high blood pressure, thyroid disorders, or diabetes before taking Ducof LS Syrup.
  • Do not take more than the recommended dose, as overdose may cause rapid heartbeat, nervousness, or tremors.
  • Consult your doctor if your cough lasts more than a few days, worsens, or is accompanied by fever, breathlessness, or chest pain.
  • Do not use Ducof LS Syrup without medical advice in children, pregnant or breastfeeding women.

Frequently asked questions

Ducof LS Syrup is used to treat cough with mucus (wet or productive cough). It helps thin and loosen phlegm so it can be coughed out more easily and also relaxes the airway muscles to improve breathing. It contains ambroxol, a mucolytic that thins mucus; guaifenesin, an expectorant that reduces mucus stickiness; and levosalbutamol, a bronchodilator that relaxes airway muscles. Because it works by clearing mucus, it is usually not recommended for dry cough where little or no phlegm is present. Use it only as advised by a doctor.
Ducof LS Syrup is generally safe when used as prescribed, but some people may experience nausea, vomiting, diarrhea, stomach pain, dizziness, headache, tremors, palpitations, or muscle cramps.

Stop the medicine and contact your doctor if you develop severe rash, breathing difficulty, fainting, a very fast heartbeat, or persistent vomiting or diarrhea.
Ducof LS Syrup should not be used by people who are allergic to any of its components. Ducof LS Syrup may interact with medicines such as beta-blockers and other drugs used for heart or breathing conditions.
