What are they?
Your doctor may choose to prescribe a JAK inhibitor if other medications aren’t an option for you, or if they aren’t controlling your AD symptoms. JAK inhibitors for moderate-to-severe AD are oral medicines (i.e., taken by mouth) and may be used with or without topical corticosteroids.
JAK inhibitors require a prescription from your healthcare professional.
How do they work?
JAK inhibitors interfere with immune signals in the body to help lower inflammation. JAK inhibitors lower the activity of an enzyme in your body called JAK, which stands for “Janus kinase”. JAK normally helps to turn on your immune system when you need it. However, if it’s too active, it can lead to inflammation.
In people with AD who have inflammation, JAK inhibitors can improve the condition of the skin and reduce itching, flares, and overall symptoms of AD.
How often do you use them?
JAK inhibitors are taken daily at about the same time each day.
How are they administered?
JAK inhibitors come in the form of tablets and are taken by mouth.
You may need blood tests before you start taking a JAK inhibitor. These tests may be repeated to help your healthcare professional know how the medication is affecting your blood and liver.
What are the possible side effects?
JAK inhibitors may cause side effects such as: throat and nose infections, cough, bronchitis, pneumonia, headache, dizziness, nausea, vomiting, cold sores, infections, Herpes Zoster (shingles), back pain, acne, weight gain, inflammation of the hair follicles, flu (influenza), pain in your belly, fatigue (feeling unusually tired and weak), and allergic reactions (trouble breathing, chest tightness, wheezing, severe dizziness or light-headedness, hives, or swelling of the lips, tongue or throat). JAK inhibitors may also cause abnormal blood test results.
Serious warnings and precautions for JAK inhibitors include increased risk for developing serious infections that may lead to hospitalization or death; lymphoma, skin cancer and other cancers; blood clots; and major heart-related problems like heart attack or stroke.
