Carmol 40 is a topical solution used to prevent dry, itchy and rough skin, according to WebMD. Some conditions that may warrant the use of Carmol 40 include eczema, kertatosis and xerosis. Carmol 40 includes two different types of ingredients: emollient ingredients, which trap water under an oily layer on top of the skin, and keratolytic ingredients, which soften the skin.
Many people who use Carmol 40 do not experience significant side effects; however, some complications that can occur include burning, itching, redness, stinging and general irritation, as explained by WebMD. Although rare, some patients have reported serious allergic reactions, which result in swelling of the face, tongue or throat; rash; severe dizziness; and trouble breathing.
Carmol 40 contains urea, lactic acid and salicylic acid, and patients should let their physicians know if they have any allergies to these or any other keratolytic ingredients, as WebMD advises. This medication can make certain users more sensitive to the sun. Doctors or pharmacists may suggest the continued use of a strong sunscreen and additional protective clothing during prolonged exposure to the sun. It is best to discontinue the use of tanning beds or sunlamps when applying this medication on a regular basis.
