Product information


Solaraze is a gel manufactured by Almirall. It is a non-steroidal anti-inflammatory drug used in the medication of actinic keratosis. It is applied to the affected patches of skin for a period of up to 90 days. You need a prescription to buy Solaraze in the UK.

Actinic keratosis (or solar keratosis) is a skin ailment caused by prolonged exposure to ultraviolet light. It generally affects older people who have spent long periods in the sun over several years.

It is extremely common, affecting more than 20 percent of those over 60. It manifests as very small patches of scaly skin usually on the legs, arms, hands, face or forehead. In men it may also occur on bald areas of the scalp and the ears. The size of the affected area varies from a pinprick to a diameter of up to three centimetres, and the patches often become very rough and bumpy, resembling warts.

Factors that can increase your susceptibility to actinic keratosis are having fair skin that burns easily, working outside, having outdoor hobbies or living in a hot country. As the disease is caused by ultraviolet light, the use of tanning machines also increases risk.

Lesions may often disappear after a short period but the areas of skin can become irritated and sore, and people can have several keratoses at the same time. In a small proportion of cases it can lead to the skin cancer squamous cell carcinomaif left untreated. If your doctor believes there is a risk of this, or your symptoms are severe, they may advise treatment. This may include Solaraze gel and regular monitoring with your physician.

Solaraze usually forms a course of treatment lasting between 60-90 days. The active component, diclofenac sodium, is thought to work by inhibiting the ability of the enzyme cyclo-oxygenase to produce prostaglandins. These are organic compounds which can promote inflammation in the body.

Please note that we do not offer this medication through our site. Contact your GP if you are seeking treatment for keratosis, or are looking to renew your prescription.
