Upsides
- Works to clear nasal congestion and helps you breathe better.
- Helpful in relieving congestion-related headaches.
- Has fewer side effects than other decongestants like pseudoephedrine.
- It doesn't raise your blood pressure and heart rate as much, or cause as much trouble falling asleep.
- Doesn't give you rebound congestion (worse symptoms when you stop taking it) like nasal spray decongestants do.
- Dayquil Cold And Flu (Acetaminophen / Phenylephrine / Dextromethorphan) is a combination medicine that relieves multiple cold symptoms. It's good to use if you have a stuffy nose, a cough, fever, and pain.
- The decongestant (phenylephrine) has fewer side effects than other decongestants like pseudoephedrine. It doesn't raise your blood pressure and heart rate as much, or cause as much trouble falling asleep.

Downsides
- Phenylephrine doesn't last as long as other decongestants like pseudoephedrine (Sudafed).
- You shouldn't use it if you have high blood pressure.
- Can make your heart race or make you feel anxious and restless.
- Shouldn't use it before you want to sleep.
- Not as effective after using it for 4 days in a row.
- If you don't really need all of the medications in this combination, you're taking extra medicine and might have extra side effects for no reason.
- Phenylephrine doesn't last as long as other oral decongestants like pseudoephedrine.
- You shouldn't use it if you have high blood pressure.
- To avoid hurting your liver, you have to keep track of the total amount of acetaminophen (APAP) you're taking since it's a very common ingredient in pain and cold/flu combination medicines.
