  • Phenylephrine Hydrochloride which is a decongestant, it shrinks the blood vessels in the nose and sinuses which opens the airways helping you to breathe more easily.

Flu Relief Capsules with Decongestant are used for the relief of the symptoms of colds and flu including aches, pains and feverishness, headache, nasal congestion and sinus pain.

  • medicines for nausea or sickness, such as metoclopramide or domperidone
  • colestyramine for high cholesterol or high blood fats
