MY daughter who is 17, has a really bad cough. She has had a cold for about a week. her firends have had the same symptoms. She is not really producing any mucus with the cough. A teacher told her when she had this virus, she took Tessalon Pearls. I have looked into these but they look kind of dangerous. Also, she takes Sertraline daily. (She also takes Trazodone at night sometimes) I am not sure they would be the best option, but she is really struggling with this cough, and was coughing a lot during the night despite trying delsym cough syrup. What do you think about the Tessalon pearls? and can you recommend something else.
