How should the usage and dosage of Nintedanib/Vigat capsules be regulated?

Nintedanib (Nintedanib) capsules are prescription drugs that require long-term and standardized use. Its dosage and usage must be strictly followed by the doctor's instructions. The standard recommended dose is 150 mg taken orally twice daily, approximately 12 hours apart. The drug should be taken with food to reduce gastrointestinal adverse reactions. At the same time, the capsule should be swallowed whole. Do not chew, crush or open the capsule, because the internal drug activity is strong and contact with the contents may cause irritation to the skin or mucous membranes. If the patient accidentally comes into contact with the powder in the capsule, he should wash it thoroughly with water immediately.

If the patient misses a dose, he or she should not take the extra dose and should take the dose as normal at the next scheduled time. Excessive dosage will not only not enhance the efficacy, but may increase the risk of abnormal liver function or gastrointestinal reactions. For patients who cannot tolerate the 150 mg dose (such as severe diarrhea or elevated liver function), the doctor can adjust the dose to 100 mg twice daily. During long-term treatment, liver enzymes (ALT, AST) and bilirubin levels need to be tested regularly to ensure safe use.

Nintedanib treatment needs to be continued, and discontinuation of treatment midway is generally not recommended because sudden interruption may lead to disease progression. If patients experience serious adverse reactions (such as persistent diarrhea, significant liver enzyme elevations, or bleeding tendencies), they should contact their physician immediately to evaluate whether a suspension or dose reduction is needed. For patients taking concomitant anticoagulants or NSAIDs, doctors need to comprehensively assess the risk of bleeding before deciding whether to use them together. In addition, nintedanib is contraindicated during pregnancy or lactation, and female patients must take effective contraceptive measures during treatment and for at least 3 months after stopping the drug.

In general, the principle of taking nintedanib can be summarized as "Three determinations": quantitative, regular, and regular meals. Taking medication regularly and adjusting dosage as directed by your doctor are the keys to ensuring efficacy and safety. Through long-term standard treatment, nintedanib can significantly delay the progression of pulmonary fibrosis and provide patients with a longer stable period.
