Take orally once daily exactly as prescribed, preferably in the morning on an empty stomach 30–60 minutes before breakfast with water. Avoid taking with calcium/iron/antacids or multivitamins; keep a 4-hour gap. Use the same brand consistently and do not stop or change dose without medical advice; dose is adjusted based on TSH/T4 tests.
