I would recommend you first try treatments such as breathing steam, or keeping a vaporizer in the room. You can use a saline nasal rinse or spray for nasal congestion or dryness. Also be sure to maintain adequate hydration, typically 8-12 eight ounce glasses of water daily unless directed otherwise by your doctor.
It is important you talk with your doctor prior to starting any new prescription or over-the-counter remedies, and to let your doctor know of any ailments or new symptoms you experience.
