Benzonatate: You can try benzonatate (tesalon perles) which is a non-narcotic cough suppressant that you take by mouth three times a day. Tell your doctor your medical history, allergies, and other symptoms. When did your symptoms start?Do you have any fever or shortness of breath? If so, go get seen in person. If you have a cough but no fever/chills/shortness of breath, healthtap physician in NJ. Good luck.
