Hypothyroidism

Thyroid care that reads your full chart, not just your last TSH.

Clara reads your full thyroid history, lab results, medications, and interactions. Our physicians sign off on every dose and every lab order.

Clara: Your labs show an elevated TSH and high thyroid antibodies, consistent with Hashimoto's thyroiditis. I can draft an updated levothyroxine dose for physician review. Are you experiencing any new symptoms?

Values and scenarios shown are illustrative examples only. All clinical assessments are individualized and reviewed by a licensed physician.

How it works

Records synced, thyroid panel read in context, dose drafted, then Clara tracks TSH on schedule.

Connect your records

Clara auto-syncs your records from 150,000+ doctors' offices, hospitals, labs, and pharmacies. Before anything is prescribed, Clara reads every TSH and Free T4 you have had drawn, any TPO or TgAb antibody results, your weight trend, your resting HR from wearables, and every medication on your chart. Free to start, no credit card.

A dose grounded in your data

Clara reads your TSH history, your symptoms, and any prior levothyroxine doses, then drafts an appropriate starting dose or dose adjustment based on your weight and medical history. Clara also checks your full medication list for any interactions before drafting a plan. Every change is reviewed and signed off by a licensed physician.

Regular retesting

Clara orders a repeat TSH at 6 to 8 weeks after any dose change, not at your next annual visit. Plans start at $25/mo for physician-approved prescriptions and lab orders. Standard ($50/mo) and Concierge ($150/mo) plans include bundled biomarker panels that capture thyroid, metabolic, and nutrient markers in one pass.

Symptoms

Common symptoms patients describe with an underactive thyroid.

Persistent fatigue not fixed by sleep

Unexplained weight gain

Cold intolerance

Dry skin and hair thinning

Constipation

Low mood and brain fog

Heavy or irregular periods

Bradycardia on your wearable

These symptoms overlap with perimenopause, iron deficiency, sleep apnea, and depression. Clara reads all of that context at once rather than anchoring on the first plausible explanation. If TSH alone is not enough, Clara recommends other labs that might provide a better picture.

Treatments

Levothyroxine dosed to your weight and TSH, with monitoring on the right cadence.

Rx · First-line

Levothyroxine (T4)

The standard of care for primary, secondary, and tertiary hypothyroidism. Clara sizes the starting dose by weight per the Synthroid label and flags interactions with calcium, iron, PPIs, estrogens, and bile acid sequestrants before drafting. Clara also checks the timing of supplements and other medications that affect absorption.

1.6 mcg/kg

Full-replacement daily dose per the Synthroid label, Section 2.1 ¹

Monitoring · Hashimoto's

Autoimmune thyroiditis

TPO antibodies indicate Hashimoto's, which is a common cause of hypothyroidism. Clara folds antibody status into the plan, monitors for associated deficiencies (B12, vitamin D, ferritin), and surveils thyroid function on schedule even when TSH is in range, because patients with Hashimoto's can see their thyroid function decline over time.

Longitudinal

Tracked across every panel

Supportive · Nutrients

Iron, B12, vitamin D

Persistent fatigue on levothyroxine isn't always a dose issue. Nutrient deficiencies like low ferritin, B12, or vitamin D can contribute and are worth checking. Clara reads these alongside your TSH to help identify what may be driving the symptom. Nutrient labs are included in the Standard and Concierge biomarker panels.

The AI difference

Understanding your thyroid means reading years of data, not just the latest result.

TSH levels can change over time. Levothyroxine absorption changes with iron, calcium, PPIs, estrogen, and age. Hashimoto's slowly reduces thyroid function over time. The pattern that matters lives across years of labs, not just the last panel.

Reads every TSH you have ever had drawn

Clara auto-syncs from 150,000+ medical sources and cross-correlates every TSH, Free T4, antibody result, and resting HR in one pass. Single bad readings get context. Multi-year trends get surfaced.

Checks for medication interactions before prescribing

Calcium, iron, PPIs, estrogens, SSRIs, rifampin, bile acid sequestrants, soy, and coffee all affect levothyroxine absorption. Clara checks the full label against every medication and supplement on your chart before drafting a dose change.

Questions don't wait for office hours

Palpitations on a new dose. Cold intolerance that has gotten worse. A wearable resting HR that dropped 8 bpm in two weeks. Clara reads your chart and responds with context from your full history. If a dose change looks warranted, it drafts a summary and routes it to a physician for review.

Common questions

Thyroid questions patients actually search for.

What does Clara cost?

Connecting your medical records and chatting with Clara is free. Paid plans start at $25/month, which includes physician-approved prescriptions and lab orders but does not include bundled biomarker tests or wearable integration. Standard ($50/mo) adds 74 biomarker tests including TSH, Free T4, Free T3, and antibodies, plus wearable integration. Concierge ($150/mo) includes 108 biomarker tests and expanded panels. All plans are HSA/FSA eligible and cash-pay. Medications and ad-hoc lab orders are billed by your pharmacy or lab and may be covered by your insurance.

Can I use my insurance, HSA, or FSA?

Clara's membership is cash-pay and not billed through insurance, but every plan is HSA/FSA eligible. Prescriptions Clara's physicians write go to your pharmacy and may be covered by your plan like any other script. A levothyroxine prescription from Clara goes to your pharmacy exactly as any other script would. Ad-hoc lab orders may also be covered by your insurance when applicable.

Is Clara a real medical practice?

Yes. Clara operates through affiliated professional corporations licensed in all 50 states. All diagnoses, prescriptions, and lab orders are reviewed and signed off by licensed physicians. Clara's AI handles intake, continuous monitoring, and clinical reasoning. The physician sign-off happens before any clinical action reaches you.

How is this different from my regular doctor?

A 15-minute annual visit reviews your most recent results. Clara reads every TSH you have had drawn, every medication you have been on, and every wearable data point in a single pass, and does it every time you interact. Your PCP remains the right choice for in-person exams and anything Clara refers out. Clara fills the continuous monitoring gap between those visits.

What if I need in-person care or an endocrinologist?

Clara manages hypothyroidism remotely through labs, prescriptions, and monitoring. When something requires a physical exam, imaging, or an in-person specialist, Clara prepares a summary and helps you navigate the next steps.

How quickly does levothyroxine work?

Symptoms typically begin to improve within 2 to 3 weeks of the right dose. Steady state after a dose change is reached in approximately 4 to 6 weeks per the Synthroid prescribing information, with monitoring recommended at that interval. ¹ Clara orders the repeat TSH on schedule rather than waiting for the next annual visit.

Is my data private?

Clara is HIPAA compliant. Your medical records and wearable data are used solely to personalize your care. They are not sold to third parties and are not used to train public AI models.
