L-Thyroid 100 mcg Tablet

L-Thyroid 100 mcg Tablet is a levothyroxine (thyroxine) medicine used as thyroid hormone replacement. Each tablet contains 100 mcg of levothyroxine sodium, and the strip/box is supplied by Johnlee Pharmaceuticals, India. It belongs to the thyroid hormone class and is used to treat hypothyroidism and other conditions when a doctor prescribes thyroid hormone replacement.

How it works: Levothyroxine works by replacing the thyroxine hormone your thyroid would normally make, helping your body’s metabolism run more normally. In tablet form, L-Thyroid 100 mcg Tablet is absorbed after swallowing and then helps normalize energy, temperature control, heart rate, and other thyroid-related functions.

L-Thyroid 100 mcg Tablet is a higher-strength option compared with L-Thyroid 25 mcg Tablet, L-Thyroid 50 mcg Tablet, and L-Thyroid 75 mcg Tablet. It may be chosen for people who need a larger daily thyroid hormone dose, so it is usually used only after a clinician has reviewed thyroid tests, symptoms, age, weight, and heart health. Because 100 mcg is not a starting dose for everyone, it should not be swapped in for lower strengths without medical advice.

• Hypothyroidism (underactive thyroid)
• Thyroid hormone replacement after thyroid surgery
• Thyroid hormone replacement after radioactive iodine treatment
• Goiter management in selected patients
• TSH suppression therapy when prescribed by a doctor

• Swallow L-Thyroid 100 mcg Tablet whole with a full glass of water.
• Take it on an empty stomach, usually 30 to 60 minutes before breakfast.
• Take it at the same time every day to keep hormone levels steady.
• Do not crush, split, or chew unless your prescriber specifically tells you to.
• Separate it from calcium, iron, antacids, and multivitamins by several hours because they can block absorption.
• If you miss a dose, follow your prescriber’s instructions rather than doubling up.

Each L-Thyroid 100 mcg Tablet provides 100 mcg of levothyroxine in one tablet. The dose is taken once daily for many patients, but some people may need a different schedule or a different strength based on lab results and medical history. There is no single maximum daily dose for everyone; your doctor decides the right dose and may adjust it gradually.

Do not change your dose or stop the medicine without speaking to your doctor.
