Cufzer Syrup is used to treat cough. It works by increasing the volume of fluid in the airways, blocking the action of histamine, and facilitating the removal of phlegm. In some cases, this medicine may cause side effects such as drowsiness, dizziness, dry mouth, nervousness, stomach pain, diarrhoea, or constipation. Let the doctor know if you are pregnant or breastfeeding, taking any other medication, or have any pre-existing medical conditions.
