Leukocytoclastic vasculitis may need medicines like dapsone, and a G6PD test is done to check if your blood can safely handle such treatment. This test looks for an enzyme that protects red blood cells; if it is low, certain medicines can damage the blood. The result helps the doctor decide which treatment is safe for you. A doctor can explain your report and guide the right treatment based on it.

Scarring alopecia is a long-term condition in which hair loss can be permanent, and improvement may take time, so 3 weeks is often too early to see any change. Keep using the treatment as advised, avoid harsh products, reduce scalp irritation, and follow a gentle hair-care routine to protect remaining hair. Do not expect quick regrowth, as the main aim is to stop further damage. A doctor can review your response and adjust treatment if needed to control the condition better.

Lichen planus requiring long-term dapsone may indicate the condition is ongoing, and taking it for many years can carry risks that require regular monitoring. Keep your skin care gentle, avoid scratching, manage stress, and try to notice any triggers that worsen your symptoms. Regular blood tests and check-ups are important for monitoring side effects and keeping treatment safe. A doctor can review your current status, check reports, and decide if you should continue, adjust, or switch to a safer option.
