What are Sudafed Mucus Relief Day & Night Capsules?

These Sudafed capsules are a form of treatment that is intended to treat the symptoms of a cold and the flu, including a blocked, stuffy nose, a headache, a fever, and any other symptoms associated with the illnesses. This treatment contains two different types of a capsule that are intended to be taken during the day and at night. Both types of capsule contain two active ingredients. These are:

  • Paracetamol
  • Phenylephrine

Paracetamol is a painkiller that is found in a variety of different types of medication that also helps to treat a fever. Phenylephrine is a decongestant that works to ease congestion in the nose that has been caused by inflammation and swelling in the nasal airways. The day capsules also contain a third active ingredient, caffeine. Caffeine helps to treat drowsiness and fatigue and when combined with paracetamol, can improve the painkilling effect.


What causes a cold or the flu?

A cold or the flu are both viruses that are caused by the spread of germs, either in the air or on hard surfaces that are touched regularly. Germs get into the air through someone who is infected coughing or sneezing which can also get germs onto the hands. The symptoms of a cold are slower to become visible and are less severe than the flu.
