These capsules are used for the relief of the symptoms of colds and flu and the pain and congestion of sinusitis, including aches and pains, headache, blocked nose and sore throat, chills and feverishness (high temperature). They can also loosen stubborn mucus (phlegm) and provide relief from chesty coughs.

  • medicines to control feeling sick or being sick such as metoclopramide or domperidone
