While prevention is the best medicine, there are some times that you absolutely need your voice. For those occasions, I've found Chloroseptic spray to be quite useful. The taste takes some getting used to, but it's almost a miracle drug for short-term emergencies. If you suspect anything more than cold- or flu-induced temporary laryngitis, get thee to a doctor quick! But for those occasional emergencies, Chloroseptic is handy, and it's over-the-counter.
