Baricitinib is a prescription pill that belongs to a group called JAK inhibitors. Doctors most often use it for moderate to severe rheumatoid arthritis when other medicines haven’t worked well. It’s also approved for some other conditions and has been used in hospital settings for certain severe COVID-19 cases. This guide explains how baricitinib works, common doses, what to watch for, and practical tips for safe use.
Baricitinib blocks enzymes called Janus kinases (JAKs). These enzymes help immune cells send signals that cause inflammation. By slowing those signals, baricitinib reduces joint swelling, pain, and tissue damage in autoimmune conditions.
Usual adult doses for rheumatoid arthritis are 2 mg or 4 mg once daily by mouth. Your doctor chooses the dose based on how well you respond and your kidney function. People with reduced kidney function may need a lower dose. Always take the exact dose your prescriber gives you—don’t split or double up.
Common side effects include upper respiratory infections, nausea, increased cholesterol, and headache. More serious risks are possible: serious infections (like TB), blood clots, changes in blood counts, and liver or kidney problems. Older adults and people with a history of heart disease or blood clots seem to have higher risk.
Before starting baricitinib, your clinician will likely test for TB, check liver enzymes, kidney function, and blood counts. During treatment, expect periodic blood tests and lipid checks. Avoid live vaccines while taking baricitinib and for a short time after stopping it. If you develop a high fever, persistent cough, sudden leg pain, unusual bruising, or yellowing skin, contact your doctor right away.
Baricitinib can interact with some drugs. Probenecid (used for gout) raises baricitinib levels and is usually avoided together. Other strong interactions are less common, but always tell your provider about all medicines, vitamins, and supplements you take.
If you’re pregnant, planning pregnancy, or breastfeeding, discuss this with your doctor. JAK inhibitors may affect fetal development and are often avoided unless benefits outweigh risks.
Want to buy baricitinib? You need a prescription. Be careful with online sellers—use a licensed pharmacy and check credentials. If cost is a concern, ask your provider about patient assistance programs or generic options where available.
Bottom line: baricitinib helps many people with inflammatory conditions, but it carries clear risks that need monitoring. Talk openly with your clinician about your health history, ask how you’ll be monitored, and report side effects quickly.

Granulomatosis with Polyangiitis (GPA) is a rare, complex disease that affects blood vessels and usually requires intensive treatment. Baricitinib, although initially known for treating rheumatoid arthritis, has shown potential in managing GPA symptoms. This article explores the mechanisms of Baricitinib and its potential advantages in treating GPA, shedding light on current research and future possibilities. By understanding Baricitinib's role, patients and healthcare providers can better navigate treatment options.
