Glyzex Syrup belongs to a class of medication called 'cough and cold preparations' 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: 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. 

Glyzex Syrup is a combination of three drugs, namely: Chlorpheniramine maleate (antihistamine), Phenylephrine (decongestant), and Dextromethorphan (cough suppressant). Chlorpheniramine maleate works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine helps in shrinking the blood vessels located in the nasal passage, thereby reducing the stuffy nose. Dextromethorphan works by blocking the transmission of nerve signals from the cough center in the brain to the muscles that produce cough. Collectively, it helps to provide relief from dry cough.

Take Glyzex 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 Glyzex 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 Glyzex Syrup do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

Glyzex Syrup is not recommended for children below 12 years of age. If you are about to undergo any medical tests or surgery, please inform your doctor that you are taking Glyzex Syrup . Avoid using Glyzex Syrup if you have taken medicines such as linezolid, phenelzine, selegiline, rasagiline, isocarboxazid, tranylcypromine, and methylene blue injection in the past 14 days. Drink plenty of fluids while taking Glyzex Syrup to loosen mucus.

Glyzex Syrup contains Chlorpheniramine maleate, Phenylephrine, and Dextromethorphan used to treat dry cough. Chlorpheniramine maleate helps to provide relief from allergy symptoms such as sneezing, running nose, watery eyes, itching, swelling, congestion, or stiffness. Phenylephrine helps in shrinking the blood vessels located in the nasal passage, thereby reducing the stuffy nose. Dextromethorphan works by blocking the transmission of nerve signals from the cough center in the brain to the muscles that produce cough. Thus, Glyzex Syrup helps to relieve overall cough, cold and allergic symptoms.

Cough: Coughing is the body's way of clearing irritants from the airways (such as allergens, mucus, or smoke) and preventing infection. Coughs can be productive or dry. A productive cough (wet cough) causes sputum (phlegm, mucus, and other matter) to be expelled from the lungs. Coughing is commonly caused by an allergic reaction or a viral infection, but coughing up mucus could indicate a respiratory infection. You may have a bacterial infection in your airways if you cough up thick, solid white mucus. If your mucus is clear or light-coloured, you may have allergies or minor respiratory infections, whereas yellow or green mucus indicates a respiratory infection.
