It sounds very uncomfortable to have persistent thick mucus and an uncontrollable cough despite your current treatment. Since you are already taking Bro-Zedex Syrup, which contains ingredients to thin and loosen mucus, and Mahacef-200 (an antibiotic), the lack of relief suggests that your mucus may be particularly stubborn or there could be another underlying issue.

• You might benefit from a medication specifically aimed at helping to expel mucus more effectively, such as an expectorant or mucolytic agent, but this should be prescribed by your doctor after reassessment.
• It is important to follow up with your prescribing doctor or a pulmonologist (lung specialist) to evaluate your symptoms further, as persistent mucus and cough can sometimes indicate infections, bronchitis, or other respiratory conditions needing tailored treatment.
• Meanwhile, continue to stay well hydrated and avoid irritants like smoke or strong fumes, which can worsen mucus production.
• If you experience worsening symptoms such as difficulty breathing, chest pain, high fever, or coughing up blood, seek emergency medical care immediately.

Please consult your doctor or a pulmonologist promptly to review your treatment and consider additional or alternative medications to help clear the mucus safely and effectively.To narrow down potential causes, we will need some more information.I understand you've been having a very wet cough for a week and haven't found relief from your current medication.
