An expectorant is a phlegm-thinning drug that is used to treat coughs with phlegm and relieve breathing when you have a cold, flu, or allergy cough. This drug is available in the form of tablets, capsules, syrup and suspension.

Expectorants work by thinning phlegm that clogs the respiratory tract, so that phlegm is more easily expelled when coughing. That way, breathing becomes more relieved and coughs heal faster.

Expectorants can be found in single drug form or in combination with other drugs in cold and cough products. There are expectorant drugs that are sold freely and some that must be purchased with a doctor's prescription.

Precautions Before Taking Expectorants

Expectorants should not be used carelessly. There are several things that must be considered before using this drug, namely:

  • Do not take expectorants if you are allergic to this drug. Always tell your doctor about any allergies you have.
  • Consult your doctor about using an expectorant if you are pregnant or breastfeeding.
  • Do not drive a vehicle or do activities that require alertness after taking expectorants, because these drugs can cause drowsiness and dizziness.
  • Do not give expectorants to children unless directed by a doctor.
  • Consult your doctor about using an expectorant if you have or have ever had tuberculosis , asthma, chronic bronchitis , emphysema , chronic cough, coughing up blood , or electrolyte disturbances .
  • Tell your doctor if you have thyroid disease, kidney disease, heart disease, Addison's disease , myotonia congenita (a genetic muscle disorder), or hyperkalemia .
  • Tell your doctor if you have diabetes, phenylketonuria , or liver disease. Expectorant medications in syrup or suspension form generally contain sugar, aspartame, alcohol, or other substances that people with these conditions need to avoid.
  • Drink more water while taking expectorants, as these medications use water from your body to thin phlegm.
  • Talk to your doctor about using expectorants if you are taking other medications, supplements, or certain herbal products.
  • See a doctor if your symptoms do not improve or are accompanied by fever, sore throat, skin rash, or persistent headache after 1 week of using the expectora.
  • Immediately consult a doctor if you experience an allergic drug reaction or overdose after taking expectorants.
