Periway Syrup is a combination of two drugs, namely: Levodropropizine and Chlorpheniramine maleate. Levodropropizine 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, thereby decreasing the urge to cough. Chlorpheniramine maleate belongs to the class of antihistamines (anti-allergic drugs) 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, running nose, watery eyes, itching, swelling, and congestion or stiffness. Together, Periway Syrup provides relief from cough.

If you are allergic to Periway Syrup or any other medicines, please tell your doctor. If you are pregnant or breastfeeding, it is advised to inform your doctor before using Periway Syrup. Periway Syrup is not recommended for children below 2 years of age. If you have high blood pressure, fits, glaucoma, hyperthyroidism (overactive thyroid), chronic bronchitis, asthma, cough with mucus, cough caused by smoking, chronic bronchitis or emphysema (a lung condition causing shortness of breath), chronic obstructive pulmonary disease (COPD), blockage in stomach or intestines, phenylketonuria (a birth defect that causes accumulation of amino acid, phenylalanine in the body), enlarged prostate, pheochromocytoma (tumour in the adrenal glands), kidney, liver, heart or urinary problems, inform your doctor before taking Periway Syrup.

• You are recommended to inform your doctor that you are taking Periway Syrup before undergoing any medical tests or surgery.
• Drink plenty of fluids while taking Periway Syrup to loosen mucus and protect yourself from being dehydrated or overheated during exercise and in hot weather as Periway Syrup contains chlorpheniramine maleate that decreases sweating and increases the risk of heatstroke.

Cough: Coughing is a 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.
