For Cough "I went to the doctor after 3 days because my chest hurts so much from coughing. This helped with pain, but the cough never stops. I need sleep. The first night, I had full-body chills/shakes for a few hours. Then, I tried to get up and was hit with nausea and extreme thirst. I got very little sleep. I just went through the second night, and I got nausea and extreme thirst. I think I am going to stop tonight, I need sleep. No side effects during the day except coughing 24/7."

Codeine / guaifenesin for Cough "I was coughing and vomiting so much, I had to go to urgent care. I'd been vomiting so much, I knew when my Dr also prescribed Pepcid and Zofran. I still can't eat, but I've been hydrating with water, broth, and popsicles! This medicine works well, especially together with those other two, based on my cough with vomiting. I also took some Tylenol to deal with the pain in my neck and shoulders."

For Cough "This medicine is a waste of money. I wanted to cough because of the guaifenesin, but the codeine was stopping me. Kept me awake all night. Gave me a dull, nasty headache. The pharmacist told me to not drink or eat after taking this. I was still coughing. Ended up in the ER because I needed to get fluids to get rid of the headache. Finally, a simple nebulizer treatment three times a day got rid of the cough in 3 days. Don’t abuse antibiotics, you may end up with a C. difficile infection."
