Description
ZOSTRIX CRM is a topical analgesic cream developed by Prestige Brands, Inc., designed to provide relief from various types of pain, including osteoarthritis, rheumatoid arthritis, postherpetic neuralgia, and diabetic neuropathy. The active ingredient in this cream is capsaicin, available in different concentrations ranging from 0.025% to 0.1%, depending on the formulation.
Mechanism of Action
Capsaicin works by reducing levels of substance P, a chemical in the body responsible for transmitting pain signals. By diminishing this chemical, ZOSTRIX CRM helps alleviate pain over time. Users are advised to apply the cream to the affected area three to four times daily, with noticeable relief potentially beginning within two weeks and maximum effect achieved after four to six weeks of continuous use.
Application Instructions
- Age Suitability: Primarily for adults and children aged 18 years and older, though some formulations may be suitable for children as young as 2 years. Specific product labeling should be consulted.
- Application Method: Apply a small amount to the affected area and massage until no residue remains. Hands should be washed thoroughly after application unless treating the hands.
- Frequency: Do not apply more often than every four hours.
