A patient who has a viral upper respiratory infection reports having a runny nose and a cough that prevents sleep and asks the nurse to recommend an over-the-counter medication. Which me-dication will the nurse recommend?
a. Diphenhydramine [Benadryl]
b. Fexofenadine/pseudoephedrine [Alle-gra-D]
c. Guaifenesin [Mucinex]
d. Phenylephrine drops
A
Diphenhydramine is effective in suppressing cough and also has sedative effects when used in doses to suppress cough. Fexofenadine/pseudoephedrine is a combination antihista-mine/decongestant and will not help with cough. Guaifenesin helps make coughs more produc-tive but will not suppress cough or help with sleep. Phenylephrine drops have decongestant properties.
