L-Thyro 12.5 Tablet

L-Thyro 12.5 Tablet is a levothyroxine (thyroxine) tablet used as thyroid hormone replacement. Each tablet contains 12.5 micrograms of levothyroxine sodium, a synthetic form of the hormone your thyroid normally makes. It belongs to the thyroid hormone class and is prescribed to treat hypothyroidism and other thyroid hormone deficiency states. In some patients, L-Thyro 12.5 Tablet may also be used as part of treatment to suppress thyroid-stimulating hormone when a clinician decides that is appropriate.

How it works: Levothyroxine in L-Thyro 12.5 Tablet acts like the natural thyroid hormone T4 and helps replace what the body is missing. The tablet is absorbed after swallowing, then your body converts it to the active hormone T3 to support energy use, metabolism, heart function, and body temperature control.

L-Thyro 12.5 Tablet is a low-strength levothyroxine tablet, which makes it useful when a doctor wants a very small dose increase or a cautious starting point. Because thyroid hormone needs vary a lot from person to person, this 12.5 mcg strength can help fine-tune therapy more gradually than larger tablets and may be chosen for older adults, people with heart disease, or patients who are sensitive to dose changes.

• Hypothyroidism
• Thyroid hormone replacement therapy
• TSH suppression in selected thyroid conditions
• Dose titration for sensitive patients

• Swallow L-Thyro 12.5 Tablet whole with a full glass of water unless your clinician tells you otherwise.
• Take it on an empty stomach, ideally 30 to 60 minutes before breakfast.
• Take it at the same time every day to keep thyroid levels steady.
• Do not take it at the same time as calcium, iron, antacids, or bile acid sequestrants; separate by several hours if instructed.
• If you miss a dose, take it when you remember unless it is close to the next dose; do not double up unless your doctor tells you to.
• Food, especially high-fiber meals and soy products, can reduce absorption, so consistent timing matters.

L-Thyro 12.5 Tablet provides 12.5 micrograms of levothyroxine per tablet. Depending on your thyroid labs and medical history, it may be taken once daily, but the exact schedule and maximum daily dose are set by your doctor and can be adjusted slowly over time. This is not a one-size-fits-all dose, and 12.5 mcg is often used as a cautious low dose or add-on strength rather than a full replacement dose for many adults.

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