Not necessarily: No, not per se. 'decongestant' usually refers to medications like sudafed, afrin, etc. That open up your airways. Mucinex (guaifenesin) works by loosening up the mucous so you can hack/snort/cough it out. It is safe to use if you have high blood pressure, whereas the others can raise your blood pressure.

No.: Guaifenesin is thought to act as an expectorant by increasing the volume and reducing the viscosity of secretions in the trachea and bronchi.

Nasal spray: I would not recommend either sudafed or phenylephrine as a decongestant during breastfeeding. Afrin or neo-synephrine, decongestant nasal sprays, can be used for a few days, are effective, and are not absorbed into the blood stream.

Suppresses cough: An anti-tussive suppresses cough. This is only beneficial is you are having frequent coughing spells or pain with coughing. Coughing is an important reflex that happens when the body senses something foreign or irritating in the respiratory tract. It's a way to expel that quickly and forcefully.

Variable: Mucinex (guaifenesin) is a mucus thinner and generally doesn't have a immediate impact during a cold/sinus infection. However, it can be very useful to help speed the resolution of the symptoms overall from the infection. Mucinex (guaifenesin) d with sudafed typically has a more immediate impact with drying up the nose. Caution using sudafed products if underlying high blood pressure is present.
