What is Thalix?
Thalix is an immunomodulatory drug used to treat multiple myeloma and erythema nodosum leprosum (ENL). It strengthens the immune system to fight cancer cells and reduces inflammation by blocking natural substances that cause swelling. Initially developed as a sedative, it was found to have severe teratogenic effects, leading to strict control of its use.

What is the usual dose of Thalix?
For multiple myeloma, the recommended dose is 200 mg once daily, taken at bedtime. For ENL, doses range from 100–300 mg daily, adjusted based on symptom severity and weight. Dosing for other conditions is determined individually by a healthcare provider.

How do I take Thalix?
Thalix capsules should be taken orally with water, preferably at bedtime or at least 1 hour after the evening meal. Patients taking it for ENL may need to divide the dose throughout the day. Avoid opening or handling broken capsules, as they can be harmful if absorbed through the skin.
