TOFANIB 5 MG

# Tofacitinib 5 mg ## Short Description **Tofacitinib 5 mg** is a prescription medicine known as a **Janus kinase (JAK) inhibitor**. It is used to treat certain inflammatory and autoimmune conditions, including **rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis**, when appropriate. Tofacitinib reduces abnormal immune-system activity by blocking JAK signaling pathways involved in inflammation. Because it suppresses parts of the immune system, it can increase the risk of **serious infections, blood clots, certain cancers, and cardiovascular events** in some patients. > **Important:** Tofacitinib should be prescribed and monitored by a qualified healthcare professional. It is not appropriate for every patient with an inflammatory or autoimmune disease. --- ## Key Benefits * Helps reduce inflammation associated with certain autoimmune diseases * Can improve **joint pain, swelling, and stiffness** in rheumatoid arthritis and psoriatic arthritis * Can help control symptoms of **ulcerative colitis** * May improve physical function and disease activity in eligible patients * Oral treatment that can be taken without injections * Selectively targets **JAK signaling pathways** involved in immune and inflammatory responses --- ## Uses / Indications Tofacitinib 5 mg may be prescribed for adults with certain moderate-to-severe inflammatory conditions. ### **Rheumatoid Arthritis** May be used for adults with moderately to severely active rheumatoid arthritis who have had an inadequate response or intolerance to certain other treatments. ### **Psoriatic Arthritis** May be used to reduce signs and symptoms of active psoriatic arthritis in appropriate patients. ### **Ulcerative Colitis** Tofacitinib may be prescribed for adults with moderately to severely active ulcerative colitis when appropriate conventional or biologic treatments have not provided adequate benefit or were not tolerated. ### Other Approved Uses The approved indications, age restrictions, and treatment requirements can vary by country and regulatory authority. --- ## How It Works Tofacitinib is a **JAK inhibitor**. JAK enzymes, particularly **JAK1 and JAK3**, participate in signaling pathways used by various cytokines that regulate immune responses and inflammation. Tofacitinib inhibits JAK signaling, which reduces the activity of certain inflammatory pathways. **Tofacitinib → inhibits JAK signaling → reduces inflammatory cytokine activity → decreases abnormal immune-mediated inflammation** Because the medicine suppresses immune-system activity, it can also reduce the body's ability to fight certain infections. --- ## Dosage & Administration > **Important:** Tofacitinib dosing is highly condition-specific. The 5 mg tablet is commonly used as a maintenance dose for several indications, but some conditions require different doses or treatment phases. Always follow the prescription provided by your healthcare professional. ### Rheumatoid Arthritis / Psoriatic Arthritis A commonly used adult regimen is: **5 mg twice daily** or an equivalent extended-release regimen where available and appropriate. ### Ulcerative Colitis Treatment may involve a **higher induction dose followed by a lower maintenance dose**.
