Levothyroxine Sodium

Description

Thyrox 100 is a synthetic version of the thyroid hormone Levothyroxine, used to treat hypothyroidism. It helps replace the hormone that the thyroid gland fails to produce sufficiently. Regular monitoring and dosage adjustment based on blood tests ensure its effectiveness in managing energy, metabolism, and other bodily functions.

Benefits

• Replaces missing thyroid hormone
• Regulates energy and metabolism
• Supports the treatment of thyroid disorders like hypothyroidism
• May suppress thyroid-stimulating hormone (TSH) levels in goiters or after thyroid cancer treatment

Uses and Doses

For adults, the starting dose typically ranges from 25-50 mcg/day, adjusted in 12.5-25 mcg increments every 6-8 weeks. Pediatric doses vary by age, starting at 10-15 mcg/kg/day in newborns and gradually decreasing with age. For those over 50 or with cardiac disease, the dose is 1.7 mcg/kg/day. It is essential to follow the prescribed dosage, usually taken on an empty stomach.
