Levothroid at a Glance: The Decision You're Making
Levothroid is an oral tablet form of levothyroxine, the synthetic version of the T4 thyroid hormone that the thyroid gland normally produces. We carry it across seven strengths, from 25 mcg up to 200 mcg, so the main decision when ordering is not whether the medicine is right for you - that is a decision for your prescriber - but which exact strength and package size match the regimen you have already been prescribed. Because levothyroxine dosing is highly individualized and adjusted according to clinical response and laboratory results, confirming the strength carefully is essential.
Levothyroxine products contain the same active hormone and use the same labeled strength units, but absorption can vary slightly between brands or manufacturers. If your prescription specifies Levothroid by name, order the matching strength and confirm it against your prescription label. Discuss any switch to another levothyroxine product with your prescriber because follow-up thyroid-function testing may be appropriate.
How Levothyroxine Works and What It's Used For
Levothyroxine replaces or supplements the hormone that an underactive thyroid gland fails to produce in sufficient amounts. Once absorbed, some of it is converted in body tissues to triiodothyronine (T3), the more metabolically active hormone. Together, these hormones help regulate metabolic rate, heart rate, body temperature, and energy use throughout the body. Oral levothyroxine tablets such as Levothroid are established first-line treatment for hypothyroidism in adults and children. Levothyroxine is also used for thyroid-stimulating hormone suppression in selected patients with certain thyroid cancers or after thyroid surgery, always under a physician's direction.
Because the hormone works gradually, symptom improvement in hypothyroidism unfolds over weeks rather than days. The full therapeutic effect of a dose change commonly takes four to six weeks, which is why thyroid-function tests are generally not repeated immediately after an adjustment. TSH is the principal monitoring test for most people with primary hypothyroidism, although a prescriber may also assess free T4 or use a different monitoring approach in particular clinical situations.
Strengths and Package Sizes We Offer
We stock Levothroid oral tablets in 25 mcg, 50 mcg, 75 mcg, 100 mcg, 112 mcg, 125 mcg, and 200 mcg strengths. Package sizes vary by strength: the 25 mcg, 50 mcg, and 75 mcg tablets are available in 270- or 360-count packages, while the 100 mcg, 112 mcg, 125 mcg, and 200 mcg tablets are available in 120-, 270-, or 360-count packages. Select the exact strength established by your prescriber and a quantity appropriate for your refill plan. Do not combine tablets or change strengths to reproduce a prescribed dose unless your prescriber or pharmacist has specifically instructed you to do so.
If your prescriber has you on a particular levothyroxine product for consistency, we also carry Levo-T as an alternative levothyroxine product. It can be useful for comparing available packaging and pricing before choosing a supply, but switching products should still be discussed with your prescriber because absorption can differ slightly from one levothyroxine product to another.

Taking Levothroid and Storing It Correctly
Levothroid is generally taken once daily, but the correct dose is individualized according to factors such as age, body weight, the cause and severity of hypothyroidism, pregnancy, other medical conditions, and cardiovascular status. Younger, otherwise healthy adults may be started near an estimated full replacement dose, while older adults and people with heart disease are usually started more conservatively. Dose adjustments are commonly made at intervals of about four to six weeks based on TSH and clinical response until a stable maintenance dose is reached. Children require age- and weight-based dosing with ongoing monitoring as they grow.
The general recommendation is to take levothyroxine consistently on an empty stomach, approximately 30 to 60 minutes before breakfast. Food and coffee can reduce absorption when taken too close to the dose. Calcium supplements, iron supplements, antacids, and some other medicines can also interfere with absorption and usually need to be separated from levothyroxine by several hours. Follow the timing instructions from your prescriber or pharmacist rather than changing the schedule independently.
Tell your prescriber about all medicines and supplements you use because levothyroxine has clinically important interactions. Thyroid-hormone replacement can affect the response to warfarin, diabetes medicines, and certain antidepressants, among other treatments. People with diabetes may need closer glucose monitoring when levothyroxine is started or adjusted. During pregnancy, treatment should generally be continued when needed, but dose requirements often increase, so prompt thyroid-function monitoring is important.
Adverse effects at an excessive dose resemble symptoms of an overactive thyroid and can include a rapid or irregular heartbeat, tremor, nervousness, sweating, diarrhea, or trouble sleeping. Contact your prescriber if these develop rather than reducing or stopping the medicine on your own. Seek urgent medical attention for severe chest pain, fainting, or a markedly rapid or irregular heartbeat. Levothyroxine is contraindicated in people with uncorrected adrenal insufficiency and should not be used for weight loss or obesity treatment.
For storage, keep Levothroid tablets between 68°F and 77°F, with excursions from 59°F to 86°F permitted. Protect the container from light and moisture, and avoid storing it in a humid bathroom medicine cabinet. When your order arrives, check that the strength on the label matches what you ordered, the tablets are intact, and the container is properly sealed. Keep taking the medicine at the same time each day to support consistent absorption and stable hormone levels.
