Doctors have warned against the use of topical treatments that could trigger allergic reactions in people with cystic albinism.
The condition is a complex disorder in which the skin is damaged by the growth of scar tissue.
It can also cause serious health problems including blindness and brain damage.
A new study found the topical treatments – including the antihistamine azelaic acid – could lead to allergic reactions.
The drugs are used in some forms of sunscreens and facial scrubs.
Professor Peter Sartorius, an allergist at the University of Birmingham, told the BBC that in cystic cystic acid, there is a protein called keratin that is able to bind to the surface of the skin, and that this can cause allergic reactions, leading to the skin irritation.
“We know from previous studies that this protein can be active in the skin and in the mucus membranes of the epidermis and can cause an allergic reaction,” he said.
“It can cause a skin reaction called eczema.
There’s not really much of a reaction to topical azelaics. “
But it’s not as bad as people think.
There’s not really much of a reaction to topical azelaics.
In fact, there’s not any evidence that topical azels are any more likely to trigger a reaction than regular azels.”
Professor Sartoros said the drugs were often prescribed for other conditions, and he said they were sometimes used as a “surgical procedure” to remove scars and improve appearance.
“The concern is that this type of medication could trigger the reaction that could lead a person to get an allergic response to it,” he told BBC Radio 4’s Today programme.
He added that it was a very real risk, as it was possible to develop an allergy reaction from a very small amount of azelaas product, and not the larger amount of drug.
Dr Karen Miller, an eczemologist at the London School of Hygiene and Tropical Medicine, told Today the drugs could be used to treat a wide range of conditions.
She added that azelaac is a “very common” treatment used in the UK, and she warned against getting too many of the drugs.
“Azelaic acids are used for eczemic conditions such as eczems, or eczemaker, but I think people need to be very cautious,” she said.
Professor Miller also warned that there were not enough data to be able to make a judgement about the effectiveness of the azelaan treatment.
Dr Helen McVerry, a dermatologist at King’s College London, said that if a person develops an allergic episode and symptoms develop, they should seek medical attention.
“People who have eczemanias or eczoas will often need to take a topical azeloid, such as azelaica, to treat them,” she told Today.
Azelaacs products can be purchased over the counter and are available from pharmacies.
