How long does it take to see obvious effects after taking Upatinib/Refu, and what are the rules?

Upadacitinib is a JAK inhibitor used to treat immune system-related diseases, especially rheumatoid arthritis (RA). It reduces the excessive response of the immune system and improves arthritis symptoms by inhibiting the Janus kinase (JAK) signaling pathway. Many patients have certain expectations for the therapeutic effect of upadatinib, so how long does it take to see obvious effects?

Clinical studies show that most patients with rheumatoid arthritis can feel certain effects within 4 weeks. Especially those with more severe joint swelling and pain usually see significant improvement in symptoms within 2 to 4 weeks. At around 6 weeks, patients may notice significant improvement in their joint function and morning stiffness (a symptom of limited movement in the morning). The efficacy of upadatinib reaches its peak around 12 weeks. Most patients experience significant improvement in arthritis symptoms and control of the progression of joint damage.

According to clinical research data, during this time period, approximately**70%-80%** of patients with rheumatoid arthritis can significantly improve and meet clinical improvement standards (such as the ACR20 standards of the American College of Rheumatology). After long-term use of upadatinib (more than 1 year), patients usually maintain good efficacy without significant side effects. However, some patients may require dosage adjustments, especially if they are insensitive or resistant to the drug.

The efficacy of upadatinib may vary among patients. Some patients may see results earlier, while others may take longer to feel significant effects. This difference is often related to the individual's immune system response, the course of the disease, and the severity of the disease. The effect of treatment is often closely related to the patient's medication compliance. Taking your medication on time, following your doctor's dosage recommendations, and having regular follow-up exams will significantly increase your effectiveness. If the patient does not take the medicine as prescribed or misses the medicine, it may affect the effectiveness of the medicine.
