Synthroid - Overview
Synthroid is the brand name for the medication levothyroxine and is used in the treatment of people with hypothyroidism and conditions requiring TSH suppression. People who might need a prescription for Synthroid can use Push Health to connect with a licensed medical provider who can prescribe Synthroid medication, including Synthroid tablets, when appropriate to do so..
What Is Synthroid Used For?
Synthroid prescription medication contains levothyroxine sodium - a synthetic form of the T4 thyroid hormone naturally produced by the thyroid gland. It is used to replace thyroid hormone in patients with hypothyroidism (an underactive thyroid), to suppress TSH in patients with thyroid cancer following thyroidectomy, and in some patients with thyroid nodules or goiter. Synthroid medication is not used for transient hypothyroidism during the recovery phase of thyroiditis.
Synthroid medication, similar to Euthyrox, Levoxyl, Tirosint and Unithroid - contain the same active ingredient at similar doses. The most important practical consideration when using Synthroid or any levothyroxine product is consistency. Patients should use the same specific formulation consistently rather than alternating between different brands or between brand and generic. For complete clinical information on levothyroxine, see the levothyroxine page.
Synthroid - Dosage and Cost
Synthroid tablets are available in 13 strengths ranging from 25 mcg to 300 mcg, color-coded to reduce dispensing errors. The appropriate dose is highly individualized and depends on age, weight, the severity of hypothyroidism, the presence of cardiac disease, and other factors. Dose determination and adjustment is guided by periodic TSH monitoring - a TSH test is typically rechecked 6-8 weeks after any dose change.
Synthroid should be taken once daily on an empty stomach, 30-60 minutes before breakfast or coffee. It can also be taken at bedtime, at least 3-4 hours after the last meal, as an alternative that avoids morning timing challenges. For complete food and drug interaction information, see the levothyroxine page.
Synthroid is a branded medication and is more expensive than generic levothyroxine when not covered by insurance - typically $10-25 or more per month depending on dose and pharmacy. Generic levothyroxine is significantly more affordable at approximately 15 cents per tablet and is bioequivalent to Synthroid. Some patients and providers prefer to remain on Synthroid specifically for consistency. Prescription savings cards and manufacturer copay cards may help reduce Synthroid costs for eligible patients.

Synthroid - Frequently Asked Questions
Is Synthroid the same as levothyroxine?
Yes. Synthroid is a brand-name tablet containing levothyroxine sodium — the same active ingredient found in generic levothyroxine and other branded thyroid medications such as Levoxyl, Tirosint, and Euthyrox. All are bioequivalent and interchangeable by FDA standards, though many clinicians recommend that patients remain on whichever specific formulation they are stabilized on, rather than switching frequently. For complete information on levothyroxine, see the levothyroxine page.
Should I take Synthroid or generic levothyroxine?
For most patients with hypothyroidism, generic levothyroxine is appropriate and significantly more affordable - typically about 15 cents per tablet vs. $0.30–$1 or more for branded Synthroid. The FDA considers them bioequivalent. Some patients and providers prefer to stick with Synthroid for consistency, particularly patients with narrow target TSH ranges such as those being treated for thyroid cancer. If you are currently stable on one formulation, it is generally advisable to continue with it rather than switching.
What is the difference between Synthroid and Tirosint?
Synthroid is a standard levothyroxine tablet with a number of inactive ingredients (acacia, lactose monohydrate, magnesium stearate, etc.). Tirosint is a levothyroxine gelcap that contains only the active ingredient plus a small number of inactive ingredients (gelatin, glycerin, water) — no dyes, gluten, lactose, or acacia. Tirosint is sometimes preferred for patients who have absorption issues with standard tablets, sensitivities to tablet excipients, or GI conditions that may affect levothyroxine absorption. It is generally more expensive than Synthroid.
Can I get a Synthroid refill online?
Yes. Through Push Health, patients who need a Synthroid prescription renewal or refill can connect with a licensed medical provider for a quick online consultation. This is particularly useful for patients between primary care appointments or who have relocated and need a new prescriber.
What time of day should I take Synthroid?
Synthroid is most commonly taken in the morning on an empty stomach, 30–60 minutes before eating or drinking coffee. Coffee, calcium supplements, iron supplements, and several other substances can reduce Synthroid absorption if taken too close to the dose. An alternative is bedtime dosing — at least 3–4 hours after the last meal — which avoids morning timing challenges. For complete food and drug interaction information, see the levothyroxine page.
Synthroid - Side Effects
When taken at the correct dose, Synthroid is generally very well tolerated and most patients experience symptom improvement rather than side effects. Adverse reactions that can result from excessive Synthroid use include fatigue or tremors, heat intolerance, weight loss, hair loss, nausea, dizziness and palpitations. Signs that the Synthroid dose might be too low include persistent fatigue, weight gain, cold intolerance, and brain fog.
Prior to using Synthroid, it is important to discuss possible side effects with one's medical provider and pharmacist. Moderate alcohol use does not have a well-documented direct pharmacokinetic interaction with Synthroid but patients should discuss alcohol consumption with their medical provider before using it while taking Synthroid medication. People with a known hypersensitivity to levothyroxine or any component of Synthroid medication should not use Synthroid prescription tablets. Patients with concerns about specific inactive ingredients in Synthroid tablets may find that Tirosint - a levothyroxine gelcap with a simpler formulation - is better tolerated.
