Analysis of possible adverse reactions of Clofazimine

Clofazimine (Clofazimine) is an effective anti- leprosy drug, but during clinical use, patients may experience some adverse reactions. Usually, the occurrence of these adverse reactions is closely related to factors such as the dosage of the drug, the length of treatment, and individual differences. Understanding the possible side effects of clofazimine is important for clinicians to manage the treatment and safety of their patients.

First, the most common adverse effects of clofazimine are skin-related problems. About half of patients will experience skin changes during treatment, including skin discoloration (especially black or red patches), dryness, itching and other symptoms. Skin discoloration is one of the most typical side effects of clofazimine. It usually manifests as red or brown discoloration of the skin and conjunctiva (the white part of the eye). This condition usually recovers gradually after stopping the drug, but it may also last for a long time. Skin pigment changes are caused by clofazimine reacting with pigments in the skin. This reaction usually does not require treatment but may have an impact on the patient's appearance.

Secondly, gastrointestinal discomfort is also one of the common side effects of clofazimine. Patients may experience gastrointestinal discomfort symptoms such as nausea, vomiting, abdominal pain, and diarrhea. Although these symptoms are usually mild, in some cases they may lead to reduced compliance with treatment and affect the effectiveness of treatment. If a patient develops severe gastrointestinal discomfort while taking clofazimine, the doctor may adjust the dose or change the medication regimen.

In addition to skin and gastrointestinal effects, clofazimine may cause some rare side effects. For example, long-term use of clofazimine may have adverse effects on the eyes, including dry eyes and blurred vision, especially when used at high doses. Eye symptoms are usually mild, but patients still need regular eye exams to ensure their eyes are healthy.
