Equate Nite Time Cherry Flavor Multi-Symptom Cold/Flu Relief is Walmart's generic version of Nyquil. They both have the same ingredients and the same doses. Each has acetaminophen (generic Tylenol) to relieve pain and reduce fever, dextromethorphan to suppress coughing, and doxylamine succinate, an antihistamine to reduce congestion. The label says that this product causes "drowsiness" but it knocked me out and woke up 12 hours later. I'm not complaining; I needed the sleep, but you might not want to take this if you have to work or be alert, thinking that you'll just get a bit drowsy. The cherry flavoring didn't do too much to mask the medicinal taste, so I use the capsule form now instead (same dose, same ingredients as the liquid, and less messy, too.) The real test is how well this worked: for me, this is very good if you only have a mild case of the flu. It helped somewhat with the cough and pain and fever, but I have had prescription strength flu medicines that worked better, but if you can't get to a doctor's office when you have the flu, Equate Nite Time does a good job of lessening (but not entirely alleviating ) the symptoms.
