Expectorants are medications that break apart mucus and make it easier to cough up and expel from your body. There are many over-the-counter expectorants available at drug stores, but you can go to your doctor for a prescription as well.
The cough medicine I have has Dextromethorphan HBr, USP 15 mg per dose. I also have a bottle of vicks vaporub I'm inhaling but with little effect. I have Mucinex but my lungs feel pretty much clear now (the congested phlegmy phase is past) so I didn't think I needed an expectorant.
