About Oncet CF Syrup

Oncet CF Syrup is primarily used to treat common cold symptoms and allergies like sneezing, runny/stuffy nose, fever, headache, body pains, congestion, or watery eyes. The common cold is a respiratory illness affecting the nose and throat. It is mostly caused by viruses known as rhinovirus.

Oncet CF Syrup is a combination of Paracetamol, Phenylephrine and Chlorpheniramine. Paracetamol inhibits the production of prostaglandins. Phenylephrine works by shrinking the blood vessels in the nasal passage. Chlorpheniramine blocks the action of histamine, which is responsible for causing allergic reactions.

Some people may experience drowsiness, nervousness, headache, dizziness, blurred vision, constipation, and dry mouth. Most of these side effects do not require medical attention and gradually resolve over time. However, if the side effects persist, please consult your doctor.

Please tell your doctor if you are allergic to Oncet CF Syrup or any other medicines. If you are pregnant, it is advised to inform your doctor before using Oncet CF Syrup. Do not use Oncet CF Syrup if you are breastfeeding without a doctor’s advice, as it may be excreted in breast milk and cause harm to the baby.
