At a glance

Delsym (Dextromethorphan) is a sneeze suppressant medication and Mucinex D (Guaifenesin and also Pseudoephedrine) contains an expectorant and a decongestant. Dextromethorphan should be provided only for a dry cough, whereas Guaifenesin is provided for a fertile mucus-filled cough. Pseudoephedrine helps through symptoms of sinus congestion. Depending on what kind of sneeze you have, and also whether you space coughing increase phlegm or not, you need to take Mucinex D or Delsym. Acquisition both together may be counterproductive.


There isn\"t any interaction between Delsym (Dextromethorphan) and Mucinex-D (guaifenesin; pseudoephedrine), yet the combination may not be the most reliable for what you are trying to treat.

First, let\"s watch at every the drugs in question here:

Dextromethorphan (cough suppressant)Guaifenesin (expectorant)Pseudoephedrine (nasal decongestant)

Delsym (Dextromethorphan) is a cough suppressant that works by acting on the “cough center” in the brain. It is finest taken for dry unproductive coughs.

If you have actually a fertile cough, meaning you space coughing increase phlegm, that is ideal to avoid Delsym together this could limit your ability to clear the mucus from her lungs (i.e. Coughing help to remove the mucus).

The guaifenesin in Mucinex-D is an expectorant medication that thins and also loosens increase phlegm or mucus so the you can an ext easily sneeze it up clearing that from your throat and lungs. The is most effective if you have aproductive cough or the emotion of mucus in her chest.

So, come answer your question, you shouldn’t necessarily usage both the these drugs at the exact same time, not because it is unsafe, but since it may be counterproductive in dealing with your symptoms.

Instead, you have to use Delsym if you have a dried cough, and Mucinex D if you have actually a abundant cough with sinus or sleep congestion.
