Did the doctor prescribe both of these medications at the same time for you?
What are your symptoms or diagnosis?
How long have you been coughing for?
Thanks, XXXXX XXXXX await your reply.
After 5 days of z-pack and no improvement, you must call the doctor. You probably need another round of antibiotic to treat the infection, otherwise there will be no improvement in you condition. No interactions between guaifenesin (mucinex) and other medicines have been recorded. Drink plenty of water while you are taking guaifenesin; this will help loosen the mucus. It will loosen the mucus in your lungs and encourage expectoration. It won't stop the cough. Tessalon on the other hand works to control the coughing. I do not recommend taking them together without speaking with your doctor first.
