About Onimex Syrup

Onimex Syrup belongs to the class of medicines called 'expectorants' primarily used to treat cough associated with mucus. Coughing (dry or productive) is the body's mechanism to remove irritants from the airways and prevent infection. Coughs are classified into two types: dry cough and chesty cough. A dry cough does not produce mucus, whereas a chesty cough (wet cough) produces mucous or sputum to help clear the airways.

Onimex Syrup is a combination of two drugs: Ambroxol hydrochloride (mucolytic agent) and Guaiphenesin (expectorant). Ambroxol hydrochloride acts by thinning and loosening phlegm (mucus) in the lungs, windpipe, and nose. Guaiphenesin raises the volume of fluid in the airways, lowers the stickiness of mucus, and aids in its removal from the airways. Thereby, Onimex Syrup helps provide relief from cough.

Take Onimex Syrup with or without food. Your doctor will prescribe how frequently you need to take Onimex Syrup based on your medical condition. Some people may experience nausea, vomiting, sleepiness, headache, dizziness, stomach upset and diarrhoea. Most of these side effects do not necessitate medical treatment and resolve gradually over time. However, please consult your doctor if the side effects persist or worsen.

Please inform your doctor if you are allergic to any of the components in Onimex Syrup . Consult your doctor if you are pregnant or breastfeeding. Inform your doctor if you have heart, liver, or kidney problems, stomach ulcers, thyroid disorders, diabetes, inflammation of air passages, lung disorders, or difficulty breathing. Keep your doctor updated about your medical condition and medications to rule out any potential negative effects.

Disease/Condition Glossary

Productive cough: Coughing is a body's way of clearing irritants (like allergens, mucus or smoke) from airways and preventing infection. A productive cough (wet cough) brings up sputum (phlegm, mucus and other matter) from the lungs. Cough occurs 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 a bacterial infection in the airways. If the mucus is clear or light-coloured, it indicates allergies or a minor infection in the respiratory tract, and yellow or green mucus indicates a respiratory infection.
