Cough syrup has 5 different functions, and you probably don't want all 5
- Acetaminophen: A painkiller with the same active ingredient as Tylenol. This is surprisingly easy to overdose on so be careful not to take any more acetaminophen.
- Cough suppressant: This reduces the urge to cough, which is useful for dry coughs which do more harm than good.
- Expectorant: This makes your mucus thinner so it can be coughed up more easily. If you have a lot of mucus in your lungs, you may want to cough more so mixing this with a cough suppressant is counterproductive.
- Doxylamine: An antihistamine that can make people drowsy. This is only found in NyQuil and its copycats. DayQuil does not have an antihistamine.
- Alcohol: Literally just booze. A very small amount (up to 10%), but it's not something people should be consuming by accident. Not all cough syrups have this so check the label.
You'll get better results if you use these things separately.
- Take acetaminophen or ibuprofen as needed for pain and fever. Follow the dosing directions on the bottle (you can take both).
- Take cough suppressants for DRY coughs, because they don't do much beyond give you a soar throat. Sip water to keep your throat moist.
- Take expectorants for WET coughs, to get gunk out of your lungs.
- Take whatever antihistamines or sleep aids work for you. This varies dramatically from person to person. #finance
