I seem to have a cold and am losing my voice, what's the best tx for this? Sx are mild nasal congestion, sore throat, very mild/occasional cough

Symptomatic therapy. Hoarseness due to laryngitis is common with viral upper respiratory infections, like the common cold, and should return to normal after a few days. Meanwhile, simple measures with warm, soothing liquids and menthol throat lozenges may help. Zinc lozenges may also help as well as non-prescription cold remedies that target your symptoms (nasal congestion, cough).
