Calamine, also known as calamine lotion, is a medication used to treat mild itchiness. This includes from sunburn, insect bite, or other mild skin conditions. It may also help dry out skin irritation. It is applied as a cream or lotion to the skin.
Side effects may include skin irritation. It is considered to be safe in pregnancy. Calamine is a combination of zinc oxide and 0.5% ferric oxide (Fe2O3). The lotion is produced following the addition of other ingredients such as phenol and calcium hydroxide.
Calamine lotion has been used as far back as 1500 BC. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. Calamine is available as a generic medication and over the counter. The wholesale cost in the developing world is about 0.25 to 3.85 USD per 100 ml bottle.
