Zostrix Topical Analgesic Cream is a smooth white cream for topical application.
This medicine may be useful as an additional aid in the temporary relief of the pain associated with arthritis (inflammation of joints). It may be useful for the treatment of the pain associated with post-herpetic neuralgia (the pain that comes after shingles).
This medicine contains purified capsaicin, a natural extract from chilli peppers. This medicine is believed to act on a substance in your body which is involved in the transmission of pain impulses from nerve endings near the skin and joints to the brain. It is believed that regular application of Zostrix to the affected site will, in time, reduce the amount of this substance in nearby nerve endings. With less of this substance present, Zostrix may help the pain to be less intense and in some cases block the pain completely.
