Adults and children: At the onset of symptoms, dissolve 5 pellets under the tongue 3 times a day until symptoms are relieved or as directed by a doctor. Do not use for persistent or chronic cough such as occurs with smoking, asthma, or emphysema, or if cough is accompanied by excessive phlegm (mucus) unless directed by a doctor. Stop use and ask a doctor if cough lasts more than 3 days, returns, or is accompanied by fever, rash, or persistent headache, as these could be signs of a serious condition. If pregnant or breastfeeding, ask a health professional before use. Keep out of reach of children. In case of accidental overdose, get medical help or contact a Poison Control Center right away.
