The initial sign of an emerging cold sore is a tingling, itching or burning feeling occurring on the lip, nose or cheek area. A small red bump appears after about one or two days, which turns into several tiny fluid-filled blisters. If the blisters burst, the fluid that oozes out is highly contagious. Symptoms of cold sores can last up to a week. Some people who have the infection for the first time may also experience:
Cold sores will usually heal by themselves in 7–10 days, but can take several weeks. Some people get cold sores frequently. Recurrences can often appear at the same site of a previously infected area.

Cold sores are caused by a virus called herpes simplex 1 (HSV-1) which is related to the virus that causes genital herpes.

Always inform pharmacy staff if you are taking any other medicines, or if you have any other health conditions, because some over-the-counter medicines may not be suitable for you. There are several pharmacy options to relieve the symptoms of cold sores. Anti-viral medicines can help ease the symptoms of cold sores and hasten healing. They are best used when the very first symptoms occur (in other words as soon as the tingling, itching or burning feeling starts). They are available as creams or tablets. Anti-inflammatory medicines may reduce the redness and aid healing. Some combination products contain an anti-viral and an anti-inflammatory medicine (such as hydrocortisone). Special patches can be applied to seal the cold sore, provide an ideal environment and speed healing. Other medicines that may also help symptoms and healing time are lysine (an amino acid), available as tablets or cream, or propolis cream (beeswax).
Ask your pharmacist for advice on the most suitable treatment for you.
