Contact dermatitis is an inflammatory skin reaction that occurs when the skin comes into contact with an irritating substance or an allergen. It causes redness, itching, swelling, and sometimes blistering or scaling at the site of exposure. There are two main types: irritant contact dermatitis, caused by direct damage to the skin, and allergic contact dermatitis, a delayed immune reaction to a specific trigger—with poison ivy being a classic and common example, along with nickel and fragrances. Symptoms typically improve once the trigger is identified and avoided, though treatment is often needed to reduce inflammation and relieve discomfort, especially in reactions like poison ivy exposure.

# Contact Dermatitis Treatment Summary Contact dermatitis treatment follows a stepwise approach. **Allergen avoidance** is the most effective long-term strategy for prevention. For acute flares, **hydrocortisone 1%** serves as an accessible first-line option for mild cases, while stronger topical steroids like **betamethasone dipropionate** and **mometasone furoate** are reserved for more severe reactions unresponsive to OTC treatments. **Oral prednisone** is a second-line systemic option for severe cases requiring rapid relief, though systemic side effects warrant careful dosing and tapering. **Topical tacrolimus** offers a non-steroidal alternative for sensitive areas or steroid-resistant cases.
