Understanding Mucinex Products

Mucinex D and Mucinex DM both help with coughs and colds. They have an active ingredient called guaifenesin. But, they are different because Mucinex D has pseudoephedrine, while Mucinex DM has dextromethorphan.2

Mucinex D: Guaifenesin and Pseudoephedrine

Mucinex D has a decongestant called pseudoephedrine. It might make your blood pressure go up. So, people with high blood pressure should be careful.2

Mucinex DM: Guaifenesin and Dextromethorphan

Mucinex DM doesn’t have pseudoephedrine. It uses a different ingredient to calm coughs.2 This might be a better choice for people with high blood pressure.2

The main difference is in their use for people with high blood pressure.2

Guaifenesin: The Expectorant Component

Guaifenesin is in both3Mucinex D and Mucinex DM as an expectorant. It helps by breaking down thick mucus and secretions. This makes them easier to cough up, clearing the airways.

People with chest congestion and a cough, whether or not they have2high blood pressure, can find relief. This happens because of guaifenesin’s work.

Loosening Phlegm and Thinning Bronchial Secretions

3Guaifenesin is the star in Mucinex for a reason. It makes you cough more by thinning out mucus. The cool part? It does all this without messing with blood pressure.

If you’re all congested or have a cough, Guaifenesin is here to help. Even those with high blood pressure. And for some, especially with chronic coughs, Mucinex DM might be the right pick.

Pseudoephedrine: The Decongestant in Mucinex D

Pseudoephedrine is the key decongestant in Mucinex D. It helps by narrowing blood vessels, which opens up your nose. This action also helps in draining the sinuses and reduces pressure.4 Yet, it might boost your blood pressure. This makes Mucinex D not the best pick for people with high blood pressure.1

Relieving Nasal Congestion and Sinus Pressure

Mucinex D is placed behind the pharmacy counter. It’s because it has pseudoephedrine, a decongestant, in it.1 This decongestant works by tightening blood vessels. This could spike your blood pressure.1 So, if you already have high blood pressure, Mucinex D isn’t for you. The pseudoephedrine could make your condition worse.1

On the other hand, Mucinex DM is different. It uses dextromethorphan, a cough suppressant, not a decongestant. So, it doesn’t affect your blood pressure like Mucinex D might.1

Dextromethorphan: The Cough Suppressant in Mucinex DM

Dextromethorphan is the active ingredient in Mucinex DM. It acts by changing the brain signals that start the cough reflex.45 This change can lower how often and how hard you cough, and it’s great for dry coughs. It’s safe for those with high blood pressure since it doesn’t increase blood pressure unlike pseudoephedrine.1
