Since your cough has lasted for 10 days without improvement, I highly recommend consulting a healthcare professional for a proper diagnosis rather than self-medicating with another syrup. A persistent cough can be due to underlying issues like post-nasal drip, allergies, or a mild infection that may require targeted prescription treatments. For temporary relief, identify your cough type: a dry cough may benefit from a generic suppressant like dextromethorphan, while a wet cough is better managed with an expectorant like guaifenesin or ambroxol. Meanwhile, stay well-hydrated with warm fluids and try steam inhalation. Please see a doctor to ensure you get the correct treatment.
