How does this medication work? What will it do for me?
Abrocitinib belongs to the class of medications called selective immunomodulators. Specifically, it is in the family of Janus Kinase 1(JAK) inhibitors. It is used to treat moderate-to-severe atopic dermatitis in adolescents and adults when other non-topical medications haven't been effective or cannot be used.
This medication works by blocking an enzyme called Janus kinase, a chemical in the body that starts the immune response. This immune response causes swelling, redness, itching, and pain. Abrocitinib reduces this immune response and the inflammation that occurs with dermatitis.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Blood clots: This medication may increase the chance of blood clot formation, causing reduction of blood flow to organs or the extremities. If you have a history of clotting you may be at increased risk of experiencing blood clot-related problems such as heart attack, stroke, or clots in the deep veins of your leg. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms such as sharp pain and swelling in the leg, difficulty breathing, chest pain, blurred vision, or difficulty speaking, contact your doctor immediately.
Cancer: Although not common, abrocitinib has been associated with several different types of cancer including lymphoma and non-melanoma skin cancer. Discuss any concerns that you may have with your doctor.
Cholesterol: Abrocitinib can cause increased blood cholesterol levels. Your doctor will check your cholesterol prior to starting treatment and during treatment with abrocitinib.
Driving/Operating Machinery: Abrocitinib may cause dizziness, affecting your ability to drive or operate machinery. Avoid driving, operating machinery, or performing other potentially hazardous tasks until you have determined how you are affected by this medication.
Infection: This medication can increase the risk of developing serious infections such as pneumonia, chicken pox, fungal infections, and tuberculosis. Before starting treatment with abrocitinib, your doctor may test to see if you have had tuberculosis or hepatitis. People taking abrocitinib have a higher risk of reactivation of these infections, as well as other viral infections including herpes simplex (cold sores), or herpes zoster (shingles).
If you notice signs of an infection such as fever, chills, pain, swelling, coughing, or pus, contact your doctor as soon as possible. This medication should also not be started while you have an active infection. Abrocitinib should not be used in combination with certain other medications that suppress the immune system, as this can increase the risk of severe infection.
Kidney function: People who have reduced kidney function may require lower doses of this medication. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Vaccines: Live vaccines such as yellow fever, BCG, and cholera should not be given while you are taking abrocitinib. Other vaccines may not be as effective when given during treatment with medications like abrocitinib. It is advisable to make sure all your vaccines are up-to-date before starting this medication.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. Women who may become pregnant should use effective birth control while taking abrocitinib and for at least 1 month after stopping the medication. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if abrocitinib passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children under 12 years of age.
