Relieves cold and flu symptoms.

Alka-Seltzer Plus Day Severe Cold And Flu (Acetaminophen / Dextromethorphan / Guaifenesin / Phenylephrine) is okay for multiple cold symptoms, but it's more medicine than you need if you only have one symptom.

Upsides
  • Alka-Seltzer Plus Day Severe Cold And Flu (Acetaminophen / Dextromethorphan / Guaifenesin / Phenylephrine) 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. It doesn't raise your blood pressure and heart rate as much, or cause as much trouble falling asleep.
  • The cough medicine (dextromethorphan) works well and has very few side effects.
  • The pain reliever (acetaminophen) is easier on your stomach and has fewer drug interactions than other pain medications like aspirin or ibuprofen.
  • Robitussin Dm (Guaifenesin / Dextromethorphan) is a combination medicine that relieves multiple cold symptoms. It's good to use if you have chest congestion and a cough.
  • Helps loosen the mucus and phlegm that builds up and causes productive, wet coughs.
Downsides
  • 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.
  • Guaifenesin isn’t useful if you have a dry cough without chest congestion.
  • Phenylephrine doesn't last as long as other 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.
  • Robitussin Dm (Guaifenesin / Dextromethorphan) isn’t useful if you have a dry cough without mucus or phlegm.
  • The two medications in this product could potentially work against each other. Guaifenesin makes mucus easier to cough up, while dextromethorphan (the "DM" in Robitussin Dm (Guaifenesin / Dextromethorphan)) stops you from coughing.
  • Needs to be taken more often during the day than other products with guaifenesin, like Mucinex.
  • Can cause sleepiness, dizziness, and an upset stomach.
