ABOUT DAYQUIL

Dayquil is a cold and flu OTC medication, made by a combination of products that contain 3 active ingredients: Acetaminophen, Dextromethorphan, and Phenylephrine. Most cold medications are night-time treatments, as they tend to make you feel dizzy or drowsy after taking them, however, Dayquil was designed as a day-time treatment as it does not contain doxylamine –an antihistamine that can make you feel drowsy.

  • Dextromethorphan is a cough suppressant used to temporarily relieve cough without phlegm caused by the common cold, flu, or other conditions that may affect your air passages. It works by decreasing activity in the part of the brain that triggers coughing, hence, suppressing your urge to cough.
  • Phenylephrine is a decongestant. It works by reducing swollen blood vessels in your nasal passages and also clears a stuffy nose by tightening your blood vessels, which causes less fluid to leak out.

HOW IT WORKS

PSE, the active ingredient in most forms of Sudafed relieves nasal congestion by making the blood vessels in the nasal airways narrower, thereby opening them up and allowing your sinuses to drain, so your nasal passages are no longer congested and you can breathe more easily.

CAN YOU TAKE DAYQUIL AND SUDAFED TOGETHER?

Can you take Dayquil and Sudafed together? Let’s consider the 3 active ingredients in Dayquil and their possible drug interactions. As a general rule, multi-symptom cold and cough medications should not be taken with each other, but single-symptom medications could be taken along with other single-symptom medications as long as they all do different things.

For instance, multi-symptom medication containing acetaminophen such as Tylenol, should not be taken along with other multi-symptom medication such as Dayquil since they’re both pain relievers and fever reducers. Taking both medications at the same time may be an overdose of the amount of acetaminophen recommended in 24 hours.

Dayquil also contains dextromethorphan. Medications that contain this active ingredient should not be taken along with medications that contain cough suppressants. Lastly, Dayquil contains phenylephrine which should not be combined with antidepressants, blood pressure medications, or other decongestants. With the breakdown of drug interactions, can you take Dayquil and Sudafed together? No, is the simple answer.

Sudafed is a decongestant, and the phenylephrine component of Dayquil would react to a combination of a medication that is also a decongestant, and since Dayquil is a multiple-symptom medication for cold and flu, it should not be taken together with medications such as Sudafed which provides the same benefits – relief for nasal congestion.

Therefore, taking Dayquil and Sudafed together could be an overdose of phenylephrine, which could result in:

  • Frequent vomiting
  • Irregular heartbeat
  • Severe dizziness and probably fainting
  • Hallucination
  • Shallow breath
  • Shocks and seizure

CAN YOU TAKE SUDAFED WITH MUCINIX?

Yes, Sudafed can be taken together with Mucinix if you have nasal congestion with a phlegmy cough. While Sudafed contains PSE which helps in treating nasal congestion or stuffy nose, Mucinix contains guaifenesin which helps in treating chest congestion. They’re 2 different drugs performing different functions so if you have nasal congestion and you’re coughing up a lot of phlegm, combining both drugs might not be a bad idea.

CONCLUSION

 Dayquil and Sudafed are 2 OTC medications used for temporarily treating symptoms of a cold. Although they are used to treat cold, they both have different active ingredients that make them function differently. Can you take Dayquil and Sudafed together? No. 

Dayquil has decongestant properties and so does Sudafed, taking them together may lead to an overdose of phenylephrine. Phenylephrine is the decongestant in Dayquil and it should not be taken together with other decongestants. Speak to your doctor to know what drugs to take with Dayquil or Sudafed to minimize the risk of side effects.
