About DM Syrup

DM Syrup is primarily used to treat dry cough. Coughing (dry or productive) is the body’s way of clearing irritants (like allergens, mucus or smoke) from airways and preventing infection. There are two types of coughs, namely: Dry cough and chesty cough. A dry cough is tickly and doesn't produce any vicious or thick mucus, while a chesty cough (wet cough) means mucous or sputum is produced to help clear the airways. 

DM Syrup is a combination of two drugs, namely: Chlorphenamine maleate (antihistamine) and Dextromethorphan (cough suppressant). Chlorphenamine maleate belongs to the class of antihistamines or anti-allergic that works by blocking the action of histamine, a substance responsible for causing allergic reactions.  It helps to provide relief from symptoms of allergy such as sneezing, runny nose, watery eyes, itching, swelling, and congestion or stiffness. On the other hand, Dextromethorphan belongs to the class of cough suppressants that works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Together, DM Syrup helps relieve cough, cold and allergic symptoms. 

Take DM Syrup with or without food as advised by your doctor with the help of a measuring cup. Your doctor will recommend how often you take DM Syrup based on your medical condition. Some people may experience dry mouth, throat, or nose, drowsiness, blurred vision, constipation, dizziness, restlessness or excitation. Most of these side effects of DM Syrup do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

If you are allergic to DM Syrup or any other medicines, please tell your doctor. If you are pregnant or breastfeeding, it is advised to inform your doctor before using DM Syrup. DM Syrup is not recommended for children below 2 years of age. If you have glaucoma, urinary problems, enlarged prostate, phenylketonuria (a congenital disability that causes accumulation of amino acid, phenylalanine in the body), cough with mucus or cough caused by asthma, chronic bronchitis or emphysema (a lung condition causing shortness of breath), inform your doctor before taking DM Syrup.

Disease/Condition Glossary

Cough: Coughing is the body’s way of clearing irritants (like allergens, mucus, or smoke) from airways and preventing infection. Coughs may be dry or productive. A productive cough (wet cough) brings up sputum (phlegm, mucus, and other matter) from the lungs. Cough is commonly caused as a response to allergy or viral infection but coughing up mucus is possibly an indication of infection in the respiratory tract. If you are coughing thick, solid white mucus, it indicates you may have a bacterial infection in the airways. If the mucus is clear or light-coloured, it indicates you may have allergies or a minor infection in the respiratory tract, and yellow or green mucus indicates a respiratory infection.
