It is FDA-approved to treat the following conditions in patients who have received one or more TNF (tumor necrosis factor) blocker medications without adequate relief of symptoms or intolerable side effects [<a href=\"https:\/\/www.accessdata.fda.gov\/drugsatfda_docs\/label\/2025\/203214s038,208246s025,213082s010lbl.pdf\">2<\/a>]:<\/p>\n\n\n\n<p><strong>Rheumatoid Arthritis:<\/strong> This is a long-term autoimmune condition that causes inflammation in your joints.

Xeljanz is used to treat adult patients with active psoriatic arthritis.<\/p>\n\n\n\n<p><strong>Ulcerative Colitis:<\/strong> <a href=\"https:\/\/ameripharmaspecialty.com\/conditions-treatments\/ulcerative-colitis\/\">Ulcerative Colitis<\/a> is a chronic disease that causes inflammation in your colon and rectum.

This leads to inflammation in your joints, intestines, skin, and other organs. A group of enzymes called Janus kinases (JAKs) helps send signals inside cells that lead to inflammation.<\/p>\n\n\n\n<p>The active ingredient in Xeljanz is tofacitinib, which is a JAK inhibitor. It works by blocking the action of JAK enzymes. This helps reduce the production of inflammatory chemicals in your body, which in turn lowers inflammation, pain, and joint damage [<a href=\"https:\/\/www.accessdata.fda.gov\/drugsatfda_docs\/label\/2025\/203214s038,208246s025,213082s010lbl.pdf\">2<\/a>].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-side-effects\"><span class=\"ez-toc-section\" id=\"Side_Effects\"><\/span>Side Effects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"420\" height=\"280\" src=\"https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/06\/common-cold.jpg\" alt=\"a woman holding a tissue and her aching throat\" class=\"wp-image-27571\" srcset=\"https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/06\/common-cold.jpg 420w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/06\/common-cold-300x200.jpg 300w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/06\/common-cold-330x220.jpg 330w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/06\/common-cold-86x57.jpg 86w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/06\/common-cold-167x111.jpg 167w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/06\/common-cold-280x187.jpg 280w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/06\/common-cold-370x247.jpg 370w\" sizes=\"auto, (max-width: 420px) 100vw, 420px\" \/><\/figure>\n<\/div>\n\n\n<p>Like any other medication, Xeljanz can also have some side effects.

Is Xeljanz an Immunosuppressant?<\/h4>\n\n\n\n<p>Yes. Xeljanz (tofacitinib) is an immunosuppressant medicine. It lowers your body\u2019s ability to fight off infections. That is why regular monitoring and caution are important during your treatment with this medication.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-2-how-long-does-it-take-for-xeljanz-to-work\">2. How long does it take for Xeljanz to work?<\/h4>\n\n\n\n<p>The response time to Xeljanz varies depending on the individual who uses it and the condition being treated.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For ulcerative colitis, it can take up to 8 weeks or longer to work.&nbsp;<\/li>\n\n\n\n<li>In the case of arthritis-related conditions, some patients may begin to experience symptom relief within 2 weeks, while others may take 3 to 4 months to see noticeable results [<a href=\"https:\/\/www.accessdata.fda.gov\/drugsatfda_docs\/label\/2025\/203214s038,208246s025,213082s010lbl.pdf\">2<\/a>].<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-3-can-i-take-xeljanz-during-pregnancy-and-breastfeeding\">3. Can I take Xeljanz during pregnancy and breastfeeding?<\/h4>\n\n\n\n<p>No. Xeljanz may harm your unborn child, so you should not take the medication during pregnancy. Also, breastfeeding is not recommended while taking Xeljanz and for at least 18 hours after the last dose, as the medication can pass into breast milk and may affect your baby [<a href=\"https:\/\/www.accessdata.fda.gov\/drugsatfda_docs\/label\/2025\/203214s038,208246s025,213082s010lbl.pdf\">2<\/a>].<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-4-can-i-take-vaccines-while-on-xeljanz\">4. Can I take vaccines while on Xeljanz?<\/h4>\n\n\n\n<p>Xeljanz is a medicine that weakens your immune system\u2019s ability to fight foreign pathogens like viruses and bacteria.<\/p>\n\n\n\n<p>This is why you should avoid live vaccines while on this medication. However, non-live vaccines are generally considered safe, and you can receive them.
