Refill LevothyroxineWhat is levothyroxine?
Levothyroxine is a synthetic form of thyroxine (T4), the primary hormone produced by the thyroid gland. It replaces or supplements endogenous thyroid hormone and is prescribed long-term for hypothyroidism, after thyroidectomy or radioactive iodine ablation, for goiter, and for TSH suppression in certain thyroid cancers.
Levothyroxine is the third most-dispensed prescription in the United States, with 80.9 million prescriptions written for 18.2 million patients in 2023 per ClinCalc DrugStats. The American Thyroid Association’s 2014 hypothyroidism guideline names levothyroxine monotherapy as the standard of care and recommends against routine combination L-T4/L-T3 therapy, a position reaffirmed by the 2021 joint ATA/BTA/ETA consensus statement, which found no consistent benefit from combination therapy across 14 clinical trials.
The generic name is levothyroxine. Common brand names are Synthroid, Levoxyl, Unithroid, Tirosint (a dye-free gelatin capsule), and Euthyrox. All deliver synthetic T4, but levothyroxine is classified as a narrow-therapeutic-index drug, so endocrinologists recommend staying on the same product, branded or a specific generic manufacturer, between refills and rechecking TSH if a switch is unavoidable.
Temi refills levothyroxine for patients who already have an active prescription. We don’t write new prescriptions. Starting levothyroxine from scratch requires an initial workup with a physician who can order TSH, free T4, and related labs to confirm the diagnosis and set the starting dose.
What conditions does levothyroxine treat?
- Hypothyroidism. The most common indication. Includes Hashimoto’s thyroiditis, the autoimmune cause of most primary hypothyroidism in adults.
- Post-thyroidectomy and post-radioactive iodine ablation. Full or partial thyroid removal requires lifelong thyroid hormone replacement.
- Goiter. Used to suppress TSH and shrink or prevent growth of an enlarged thyroid.
- TSH suppression for differentiated thyroid cancer. Higher doses keep TSH low after treatment of papillary or follicular thyroid cancer.
- Congenital hypothyroidism. Lifelong replacement started in infancy and continued into adulthood.
Common levothyroxine dosages
Levothyroxine comes in an unusually large number of tablet strengths so doses can be fine-tuned to TSH targets. Available strengths include 25, 50, 75, 88, 100, 112, 125, 137, 150, 175, and 200 mcg. Your physician picks the dose based on your TSH, age, body weight, and cardiovascular history.
| Dose range | Typical use |
|---|---|
| 25 to 50 mcg | Starting dose for older adults, patients with cardiac disease, or mild subclinical hypothyroidism. Start low, go slow. |
| 75 to 125 mcg | Common maintenance range for most adults with primary hypothyroidism. |
| 125 to 200 mcg | Typical post-thyroidectomy replacement or TSH-suppression dosing for thyroid cancer follow-up. |
Temi refills your existing dose. If you’re already stable on levothyroxine, our physician can refill it. We don’t adjust doses or start new prescriptions. Dose changes belong with your regular prescribing physician, who has your recent TSH.
What are the side effects of levothyroxine?
When dosed correctly, levothyroxine has few side effects because it’s replacing a hormone your body normally makes. Most problems come from under-replacement (dose too low) or over-replacement (dose too high).
Signs of over-replacement (dose too high)
- • Palpitations or fast heart rate
- • Anxiety, tremor, or insomnia
- • Heat intolerance or sweating
- • Unintentional weight loss
- • Diarrhea or more frequent bowel movements
- • Long-term: osteoporosis and atrial fibrillation, especially in older adults
Signs of under-replacement (dose too low)
- • Fatigue and low energy
- • Weight gain or difficulty losing weight
- • Cold intolerance
- • Constipation
- • Dry skin, hair thinning, brain fog
Narrow therapeutic index: same product every refill
Ask your pharmacy to dispense the same manufacturer every refill.
Levothyroxine is classified as a narrow-therapeutic-index drug. Small differences in absorption between manufacturers can shift TSH out of your target range. If you switch brands or generic manufacturers, your physician should recheck TSH 6 to 8 weeks after the change.
Cardiac caution in older patients
In adults over 50 or with coronary artery disease, levothyroxine is started low (often 25 to 50 mcg) and titrated up slowly to avoid precipitating angina, arrhythmia, or an ischemic event.
Monitoring while taking levothyroxine
After any dose change, TSH is rechecked at 6 to 8 weeks. Once stable, every 6 to 12 months is standard. Pregnancy, significant weight change, or a new interacting medication (PPIs, calcium, iron, estrogen, certain anticonvulsants) usually warrants an earlier recheck.

When and how to take levothyroxine
Absorption is sensitive to food, other supplements, and some medications. Small routine changes can meaningfully shift your TSH, which is why consistency matters.
- Take it on an empty stomach, first thing in the morning, 30 to 60 minutes before eating or drinking anything except water.
- Wait at least 4 hours between levothyroxine and calcium supplements, iron, antacids, soy products, or high-fiber foods.
- Coffee can reduce absorption. If you drink coffee in the morning, wait at least 60 minutes after the dose.
- Proton-pump inhibitors (omeprazole, pantoprazole) reduce absorption over time. Starting or stopping one usually requires a TSH recheck.
- If mornings are hard, a bedtime dose (at least 3 hours after the last meal) is acceptable. Pick one routine and stick to it.

Alternatives to levothyroxine
Levothyroxine (T4 monotherapy) is the standard of care for hypothyroidism. A handful of alternatives exist for specific situations, though they are not first-line. Your physician chooses based on symptom response, labs, and patient history.
- Liothyronine (Cytomel): Synthetic T3. Occasionally added to T4 in combination regimens for patients whose symptoms persist despite normal TSH, though the 2021 ATA/BTA/ETA consensus did not find consistent benefit.
- Desiccated thyroid extract (Armour Thyroid, NP Thyroid, Nature-Throid): Porcine-derived, contains both T4 and T3. Not recommended as first-line per ATA 2014 but still prescribed in some practices.
- Tirosint (levothyroxine gelatin capsule or solution): Dye-free and filler-free formulation for patients with allergies, severe malabsorption, or gluten/lactose sensitivity.
Temi refills any non-controlled medication you already take. Submit a request and we’ll confirm coverage before charging you.

Frequently asked questions about levothyroxine refills
Can I get a levothyroxine refill online without a new appointment?
Yes, if you already have an active levothyroxine prescription and you're stable on your current dose. You fill out a short health form, a board-certified physician reviews it, and the prescription goes electronically to whichever pharmacy you pick. No video visit and nothing to schedule.
How fast can I get my levothyroxine refill from Temi?
Most refill requests get a physician review within 24 hours. After approval, the prescription goes to your pharmacy electronically. Levothyroxine is widely stocked, so pickup is usually same-day once the pharmacy receives the e-prescription. Submit the refill a few days before you run out to be safe.
Can Temi send my levothyroxine to Cost Plus Drugs?
Yes. Temi sends prescriptions to any licensed US pharmacy, and Cost Plus Drugs is a common choice. When you submit the refill, pick Cost Plus as your pharmacy and we route it there. Generic levothyroxine is typically a few dollars for a 30-day supply at Cost Plus.
What's the cheapest way to get levothyroxine refilled online without insurance?
Pair the $15 Temi refill with a low-cost cash pharmacy like Cost Plus Drugs. Generic levothyroxine runs under $10 for a 30-day supply there, so your total out-of-pocket usually lands in the $20 to $25 range: the $15 physician review from us plus whatever the pharmacy charges for the drug itself.
What's the difference between levothyroxine and Synthroid?
Levothyroxine is the generic name. Synthroid is the most widely recognized brand. Other brands include Levoxyl, Unithroid, Tirosint, and Euthyrox. All contain the same active ingredient (synthetic T4), but because levothyroxine has a narrow therapeutic index, the American Thyroid Association recommends staying on the same product between refills and rechecking TSH if a switch is unavoidable.
Can I switch between levothyroxine brands and generics?
It's possible but not ideal without rechecking labs. Different manufacturers can produce small differences in absorption, which can shift TSH out of your target range. The American Thyroid Association's 2014 hypothyroidism guideline recommends staying on the same product you've been stabilized on. If you do switch, plan for a TSH check 6 to 8 weeks after the change.
When and how should I take levothyroxine?
Take it on an empty stomach, first thing in the morning, 30 to 60 minutes before eating or drinking anything except water. Wait at least 4 hours before calcium supplements, iron, antacids, soy products, or high-fiber foods, because these interfere with absorption. Consistency matters more than the exact time, so pick a routine and stick to it.
What should I do if I miss a dose of levothyroxine?
Take the missed dose as soon as you remember, as long as it's still the same day and you can take it on an empty stomach. If your next scheduled dose is coming up soon, skip the missed one and continue as normal. Do not double up. Levothyroxine has a long half-life of about 7 days, so one missed dose rarely causes symptoms, but consistency is what keeps your TSH stable.
Does insurance cover my Temi levothyroxine refill?
No. Temi is cash-pay and doesn't bill insurance for the $15 physician review fee. Your pharmacy can still apply insurance to the medication itself. Generic levothyroxine is inexpensive at most cash pharmacies, often cheaper than an insurance copay, so it's worth comparing Cost Plus Drugs, a local cash price, and your insurance copay before deciding.
How often do I need TSH tests while on levothyroxine?
Once your TSH is stable on a set dose, a recheck every 6 to 12 months is standard. After any dose change, your physician rechecks TSH at 6 to 8 weeks. More frequent labs may be needed in pregnancy, after significant weight change, or when starting a new medication that affects thyroid absorption or metabolism.
In which states does Temi refill levothyroxine?
California, Delaware, and Florida. We add states as we license more physicians, including through the Interstate Medical Licensure Compact. Join the waitlist at usetemi.com and we'll email you when your state opens.
What happens if a provider cannot approve my levothyroxine refill?
You get a full refund of the $15 fee plus a short clinical explanation. This might happen if your TSH labs are significantly out of date, if a new contraindication has come up, or if the requested dose doesn't match what we'd expect from your recent labs. You pay nothing unless you actually get the prescription.
