How can i help bring up mucous when i cough?

Increase Fluids: It depends on the cause of the cough but i would recommend increasing fluids. However, i would avoid dairy which seems to increase mucous production. And i would also use a guiafenesin type cough syrup which helps break up mucous. Finally, if it is a dry inflammatory cough you may need to use an anti-inflammatory inhaler or medicine as in asthma or copd.

Mucolytics: Mucolytics are medications which "thin" mucus and make it easier to expectorate (cough up). Guaifenesin is the classic example of such a medication. It is available in a short-acting syrup (robutussin) and a long-acting tablet (mucinex). Additionally, when there are other pulmonary conditions such as asthma and copd, medications which help treat these conditions will help in bringing up mucus.

Fluids...: Increasing your fluid intake will help keep your secretions thin enough to cough up easily. A non-productive cough could be a sign of other diagnoses like bronchospasm, gerd, post-nasal drip, etc. So see your doctor for any persistent, non-productive cough.
