Antihistamines topical

About topical antihistamines

Exposure to irritant substances can cause the body to produce a chemical called histamine. The release of histamine causes allergic symptoms which can include itching and swelling. Antihistamines reduce the effects of histamine and help to relieve these symptoms. They are effective when taken by mouth as tablets, but antihistamine creams (topical antihistamines) are also available to apply to the skin and can be used for short periods of time.

Some topical antihistamines preparations also contain camphor to help cool the skin and zinc oxide to help reduce the itching.

Before using topical antihistamines

Before using topical antihistamines make sure your doctor or pharmacist knows:

• If you are pregnant, trying for a baby or breast-feeding.
• If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.
• If you have ever had an allergic reaction to this or any other medicine.

How to use topical antihistamines

• Before beginning treatment, read the instructions on the container and the manufacturer's printed information leaflet.
• Apply the cream to the affected area as detailed on the container.
• Do not use this preparation for more than three days at a time. If your symptoms do not begin to improve during this time, or if they get worse, ask your pharmacist or doctor for further advice.
