Baricitinib is an oral JAK inhibitor used to treat autoimmune diseases. Standardized medication is the key to ensuring efficacy and safety, and management should be done from three aspects: usage, efficacy monitoring, and risk prevention.

1、 Standard usage and dosage

Conventional dose: The recommended starting dose is once daily, 4mg each time; for specific populations (such as those over 75 years old or those with moderate kidney function impairment), it can be reduced to 2mg per day.

Usage: Can be taken with meals or on an empty stomach. Swallow the whole tablet and do not chew or crush it. It is recommended to take medication at a fixed time every day to maintain stable blood drug concentration.

Omission treatment: If missed, it should be replenished as soon as possible when remembered on the same day; If it is close to the next medication time, skip the missed dose and do not double it.

2、 Key points of efficacy evaluation

Effective time: Clinical improvement usually begins 4-8 weeks after treatment and reaches a relatively stable effect around 12 weeks, requiring patient persistence.

Therapeutic efficacy indicators: Based on specific diseases such as rheumatoid arthritis and alopecia areata, objective indicators such as joint swelling, skin lesion range, or hair regeneration are used to evaluate.

Regular follow-up: Every 3 months, the doctor will comprehensively evaluate the efficacy. If there is not enough response within 16 weeks, the adjustment plan should be considered.

3、 Key precautions

Infection prevention and control: Screening for tuberculosis and hepatitis is necessary before medication; If there are signs of infection such as fever and cough during treatment, seek medical attention promptly.

Thrombosis risk: Those with a history of thrombosis should use it with caution; If there is sudden unilateral limb swelling or chest pain, seek medical attention immediately.

Liver and kidney function monitoring: Regularly test liver enzymes and blood creatinine before and during treatment. If liver enzymes significantly increase, discontinue medication for evaluation.
