Clofazimine treatment courses are long, and side effect management directly affects medication adherence. The following provides response points for three common reactions.

1.Skin red-brown discoloration: inform in advance, focus on psychological support

Red-brown or purple-brown discoloration of the skin and mucous membranes is the most common reaction to clofazimine, resulting from drug accumulation in adipose tissue and the reticuloendothelial system, with a high incidence.

Response points: ①Proactively inform patients before medication that this is a reversible reaction that gradually fades over months after discontinuation, to avoid self-discontinuation due to panic;②The degree of discoloration is related to cumulative dose and does not affect continued treatment, with no dose adjustment needed;③Recommend wearing dark clothing and reducing sun exposure (which can worsen pigmentation), using sun protection when necessary;④If accompanied by severe itching or rash, rule out allergic reactions and seek medical attention promptly.

2.Dry skin: moisturizing care, symptomatic treatment

The drug can reduce sebum secretion, causing dryness, desquamation, and even fissures.

Response points: ①Use a gentle moisturizer daily (those containing urea or ceramides are preferable), avoid excessively hot water and prolonged bathing;②Avoid strongly alkaline soaps and irritating skincare products;③For marked dryness, short-term topical emollient occlusion may be used, with petroleum jelly added to fissures;④If secondary eczema or infection occurs, dermatology consultation is needed, with short-term topical glucocorticoids if necessary, generally not affecting continued use of clofazimine.

3.Abdominal pain: take after meals, distinguish severity

Abdominal pain, diarrhea, and nausea are mostly related to gastrointestinal irritation and drug deposition in the intestine.

Response points: ①Insist on taking the drug with meals or immediately after meals, avoiding an empty stomach, which can significantly reduce irritation;②Eat small, frequent meals, avoiding spicy, cold, and excessively high-fat foods;③Mild abdominal pain can be observed and treated symptomatically (such as antispasmodics), while recording bowel movement frequency and characteristics;④If persistent severe abdominal pain, bloody stools, abdominal distension and vomiting, or weight loss occur, be alert to serious complications such as intestinal obstruction or intestinal bleeding, and immediately discontinue the drug and seek medical attention, with abdominal imaging if necessary.Long-term users should regularly monitor abdominal symptoms.
