Thyroneed 12.5 Tablet contains Thyroxine (12.5mcg). It belongs to the Thyroid hormone (Synthetic T4) class of medicines.
Levothyroxine is a synthetic form of thyroxine (T4), a natural thyroid hormone. It is converted in the body to the active hormone (T3) and helps regulate metabolism, energy, body temperature and growth. It normalizes elevated TSH levels in hypothyroidism.
Oral tablet. Take exactly as prescribed, usually once daily on an empty stomach 30–60 minutes before breakfast with water. Take at the same time every day; avoid taking with calcium/iron/antacids/soy within 4 hours. Dose is individualized based on TSH/T4 and clinical response.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Thyroneed 12.5mcg Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
Taking more Thyroneed than prescribed can be harmful. If you suspect an overdose, contact a doctor or go to the nearest emergency department at once, and carry the pack or strip with you. In India the emergency number is 112.
