MERICOF TABLET is used to treat cough. It works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough, thereby decreasing the urge to cough. Also, it blocks the action of histamine, responsible for causing allergic reactions. It irritates the airways, which increases the production of respiratory tract fluids and decreases the stickiness of mucus that can be coughed out easily. Thus, it helps remove mucus from the airways and helps with easy breathing. Some people may experience dry mouth, throat or nose, nausea, stomach upset, vomiting, drowsiness, headache, blurred vision, constipation, dizziness, restlessness, or nervousness. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.

About MERICOF TABLET

MERICOF TABLET belongs to a class of medications called ‘expectorants’ primarily used to treat 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 your airways. 

MERICOF TABLET contains four medicines, namely: Dextromethorphan (cough suppressant), Chlorpheniramine (antihistamine/antiallergic), Guaifenesin (expectorant), and Ammonium chloride (irritative agent). Dextromethorphan belongs to the class of cough suppressants that work by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough, thereby decreasing the urge to cough. Chlorpheniramine belongs to the class of antihistamines (anti-allergic drugs) that work by blocking the action of histamine and is responsible for causing allergic reactions. It also provides relief from allergic symptoms such as sneezing, running nose, watery eyes, itching, swelling, congestion or stiffness. Guaifenesin and Ammonium chloride belong to the class of irritants and expectorants that work by irritating the airways, which increases the production of respiratory tract fluids and decreases the stickiness of mucus that can be coughed out easily. Thus, together, MERICOF TABLET helps remove mucus from the airways and helps with easy breathing, especially.

Take MERICOF TABLET as prescribed. Your doctor will recommend how often you take MERICOF TABLET based on your medical condition. Some people may experience dry mouth, throat or nose, nausea, stomach upset, vomiting, drowsiness, headache, blurred vision, constipation, dizziness, restlessness, or nervousness.
