What Compounded Thyroid Is

When manufactured thyroid medications don't cover what you need.

Levothyroxine works well for many patients with hypothyroidism. Compounded thyroid fills the gaps — custom ratios, sustained-release T3, filler-free preparations, and non-standard doses your provider wants to prescribe.

Custom T3/T4 ratios

Manufactured combination products come in fixed ratios. Compounding lets your provider prescribe specific amounts of each hormone — say, 50mcg levothyroxine plus 10mcg liothyronine in a single capsule — based on your labs and how you respond to treatment.

Sustained-release T3

Pure T3 (liothyronine) has a short half-life — it peaks within a few hours and clears quickly. Sustained-release T3 spreads the dose over 12+ hours, which some providers prefer for stable thyroid hormone levels throughout the day.

Filler-free options

Many manufactured thyroid medications contain fillers — corn starch, lactose, dyes, gluten — that some patients react to or want to avoid. Compounded thyroid lets you and your provider specify what's in your capsules (or what isn't).

Why Compounding Matters for Thyroid

Four situations where manufactured isn't enough.

Most patients with hypothyroidism do well on manufactured levothyroxine. The patients we see at Okuley's for compounded thyroid are usually here because one of these specific situations applies.

When manufactured doses don't fit

Levothyroxine comes in fixed manufactured strengths. If your provider wants 62mcg, you can't get that from a retail pharmacy — the closest options are 50mcg and 75mcg. Compounding makes the exact prescribed dose possible.

When you need T3 added

Some patients don't convert T4 to T3 well — genetics, inflammation, nutrient deficiencies, and other factors can affect conversion. For these patients, providers may prescribe T3 alongside T4 in a custom ratio that retail pharmacies can't make.

When fillers cause problems

Manufactured thyroid products contain various fillers and excipients. Some patients are sensitive to corn, lactose, gluten contamination, or dyes — and these sensitivities can affect how the medication works. We compound with hypoallergenic fillers when your provider specifies.

When NDT supply is disrupted

Manufactured natural desiccated thyroid (Armour, NP Thyroid) has had supply disruptions over the past several years. When supply is short, we can compound T3/T4 combinations in NDT-like ratios so patients can stay on their protocol.

What We Compound

Thyroid medications we compound at our Defiance lab.

Working from prescriptions written by your provider, we compound the major thyroid hormone preparations — individually or in combinations — in the form your protocol calls for.

Levothyroxine (T4)

  • Compounded T4 capsulesFor patients who need filler-free formulations or doses between manufactured strengths
  • Hypoallergenic filler optionsFiller choices for patients with corn, lactose, or gluten sensitivities

Liothyronine (T3)

  • Immediate-release T3Standard T3 capsules for patients on a typical twice-daily dosing schedule
  • Sustained-release T3Slow-release capsules for steady T3 levels throughout the day — not available as a manufactured product
  • Custom dosesDoses below or between manufactured strengths (2.5mcg, 7.5mcg, 12.5mcg, etc.)

T3/T4 combinations

  • Custom ratio combinationsSingle-capsule combinations at the T4/T3 ratio your provider specifies
  • NDT-style ratiosApproximate 4:1 T4/T3 ratio mimicking manufactured NDT products
  • With sustained-release T3Combinations using SR T3 for stable levels

Specialty preparations

  • Liquid thyroid medicationsFor pediatric patients or adults who have trouble swallowing capsules
  • Dye-free preparationsFor patients sensitive to FD&C colorants
  • Reverse T3 considerationsProtocols where providers want to reduce reverse T3 via specific T3-forward dosing

Common Protocols

The thyroid protocols we fill most often.

Your provider designs the protocol based on your symptoms, labs, and how you've responded to previous treatment. Here are the approaches we see most commonly.

T4 with T3 added

The most common compounded thyroid protocol we fill. Patients already on levothyroxine who still have symptoms — fatigue, weight gain, cold intolerance, brain fog — have their providers add T3 (typically 5-15mcg) compounded as a separate capsule or combined with T4 in one preparation.

Sustained-release T3 protocol

For patients whose providers want stable T3 levels throughout the day rather than the peaks and valleys of immediate-release T3. Often used by functional medicine practitioners and a growing number of endocrinologists open to T3 supplementation.

Compounded NDT alternatives

When manufactured Armour Thyroid or NP Thyroid is on backorder (which has happened multiple times in recent years), we compound T3/T4 combinations in NDT-like ratios so patients can stay on their protocol without disruption.

Filler-free T4 only

For patients who do well on T4 alone but react to the fillers in manufactured Synthroid or generic levothyroxine. Compounded T4 with hypoallergenic fillers — or no fillers at all when possible.

How It Works

From comprehensive labs to ongoing optimization.

Thyroid optimization is a process, not a one-time event. Here's what to expect when starting or transferring a compounded thyroid prescription.

1

Work with a thyroid-experienced provider

Many primary care providers prescribe levothyroxine but aren't comfortable with compounded combinations or T3. Functional medicine practitioners, integrative endocrinologists, and some forward-thinking PCPs are the most common compounded-thyroid prescribers. We can suggest providers in the area.

2

Get comprehensive labs

Beyond TSH, providers typically order free T4, free T3, reverse T3, and thyroid antibodies (TPO, thyroglobulin). Comprehensive labs let your provider see the full picture rather than just the screening marker.

3

Send the prescription

Your provider sends the prescription to us electronically, by fax, or by phone. New compounded thyroid prescriptions are typically ready in 24-48 hours. Transfers from another pharmacy: we handle the calls.

4

Retest, adjust, optimize

Most providers retest labs at 6-8 weeks after a change to a compounded thyroid prescription, then every 3-6 months once you're stable. Dose adjustments are common — we adjust the compound when your provider sends an updated prescription.

Common Questions

Thyroid compounding questions, answered.

The questions we hear most from patients starting compounded thyroid, switching from manufactured products, or doing research before talking to their provider.

Why would my provider prescribe compounded thyroid instead of Synthroid or levothyroxine?
Levothyroxine works well for many patients with hypothyroidism — it's the standard of care for good reason. Compounded thyroid medications are typically prescribed in specific situations: when a patient has persistent symptoms despite normal TSH on levothyroxine alone, when a provider wants to add T3 (liothyronine) to T4 in a custom ratio, when a patient is sensitive to the fillers in manufactured products, when manufactured doses don't match what the provider wants to prescribe, or when supply issues affect manufactured natural desiccated thyroid (NDT) products. Your provider is the one making that clinical decision — we fill what they prescribe.
What's the difference between T3 and T4?
T4 (thyroxine) and T3 (triiodothyronine) are the two main hormones your thyroid produces. T4 is the storage form — your body converts it into T3 as needed. T3 is the active form that does the work in your cells. Most thyroid medications (Synthroid, levothyroxine) provide T4 only, relying on your body to convert it to T3. Some patients have trouble with this conversion — genetic factors, inflammation, nutrient deficiencies, and other variables can affect it. For these patients, providers may prescribe T3 directly (liothyronine, Cytomel) or a combination of T4 and T3. Compounding pharmacies make it possible to dial in the exact ratio.
What is sustained-release T3 and why is it compounded?
Pure T3 (liothyronine) has a short half-life — it peaks in the blood within a few hours and clears quickly. Some providers find this creates uneven thyroid hormone levels throughout the day. Sustained-release T3 is compounded with a slow-release matrix that spreads the dose out over 12+ hours, which some providers prefer for stable blood levels. Sustained-release T3 isn't available as a manufactured product, so it has to come from a compounding pharmacy. We compound SR T3 regularly.
What is natural desiccated thyroid (NDT) and do you compound it?
Natural desiccated thyroid (NDT) is thyroid hormone derived from porcine (pig) thyroid glands — manufactured under brand names like Armour Thyroid and NP Thyroid. It contains both T4 and T3 in a roughly 4:1 ratio that mimics human thyroid hormone production. We don't make NDT from actual porcine thyroid (that's manufactured by Armour and NP Thyroid). What we do compound is custom T3/T4 combinations that can mimic NDT ratios — useful when manufactured NDT is on backorder (which has happened several times in recent years) or when a patient wants a specific ratio that isn't available in a manufactured product.
Will my insurance cover compounded thyroid medication?
Coverage varies by plan. Many commercial insurance plans cover compounded thyroid, often with prior authorization required. Medicare Part D generally does not cover compounded medications. The good news is that compounded thyroid is typically affordable as a self-pay medication, and it's eligible for HSA and FSA spending. We'll run your prescription through your insurance up front and let you know your out-of-pocket cost before you commit.
How is compounded thyroid different from Armour Thyroid?
Armour Thyroid is a manufactured product made from porcine (pig) thyroid extract — it's standardized to contain T4 and T3 in a fixed ratio. Compounded thyroid lets your provider customize the T4/T3 ratio, dose, fillers, and delivery form (immediate-release vs sustained-release) — none of which is possible with Armour. Many patients do fine on Armour and don't need compounded thyroid; for those who need customization, compounding fills the gap.
Can I switch from levothyroxine to a compounded T4/T3 combination?
Only with your prescribing provider's guidance. Switching thyroid medications — especially adding T3 — affects how your body responds and how your labs read. Most providers retest your labs at 6-8 weeks after a change. Don't switch on your own; the change should always come through your provider, who'll write the new prescription with the specific T4/T3 amounts they want you to take.
Why do I have to retest labs every few months on compounded thyroid?
Thyroid hormone levels change over time, especially after starting a new medication, changing doses, gaining or losing weight, or going through stressful periods. Providers typically retest TSH, free T4, free T3, and sometimes reverse T3 every 6-12 weeks at first, then less often once you're stable. Lab-based dose adjustments are how thyroid optimization actually works — you and your provider find the dose where you feel best and your labs look right.
