Metformin Online · AI Primary Care for Type 2 Diabetes & Prediabetes

How it works

Chart in, renal and B12 checked, prescription to your pharmacy, trend watched quarterly.

Connect your records

Clara auto-syncs your records from 150,000+ doctors' offices, hospitals, clinics, labs, and wearables. The AI reads your A1C trend, fasting glucose, eGFR, vitamin B12 status, LFTs, and history of lactic acidosis against the metformin label before anything is prescribed.

Prescription to your pharmacy

A licensed physician signs the metformin prescription and it's sent to your pharmacy. Metformin is generic and reliably covered by nearly every commercial and government insurance plan — cash price is also low even without coverage.

Titrate slowly, watch the trend

Clara titrates from 500 mg daily to 1000–2000 mg daily over 4–6 weeks to minimize GI side effects⁶, rechecks A1C and eGFR every 3 months, and flags if B12 trends low. If A1C isn't at target by 3–6 months, Clara recommends adding a GLP-1 or alternate second agent.

Dosing

Metformin 101, and when to combine it with a GLP-1.

Rx · Start

Metformin IR 500 mg

Start once or twice daily with meals. Titrate up by 500 mg weekly as tolerated to the effective dose (usually 1000 mg BID). Gradual titration significantly reduces the characteristic GI side effects.

500 mg

Starting dose

Rx · Alternative

Metformin ER (extended-release)

Once-daily dosing with meals, generally better GI tolerability. Useful if IR metformin caused intolerable diarrhea or bloating. Clara recommends ER when the GI trade-off tilts clearly toward it.

500–2000 mg

Once daily

Rx · Add-on

Pair with GLP-1 if needed

If your A1C isn't at target on metformin alone after 3–6 months, guidelines support adding a GLP-1 receptor agonist like Ozempic or Mounjaro. Metformin almost always stays in place when the GLP-1 is added.

Off-label

Prediabetes and PCOS

Metformin is widely used off-label for prediabetes (supported by the Diabetes Prevention Program) and for insulin resistance in PCOS. Clara discusses these uses transparently and notes when a use is off-label before any script goes out.

Why Clara

Metformin is cheap. Getting it prescribed in context is the hard part.

The AI difference

Metformin is not "set and forget." It needs a chart-reader who never blinks.

Metformin is safe, cheap, and effective — but it has its own quirks. eGFR can change. B12 can drift low. GI tolerability can wax and wane. A1C responds fast initially, then plateaus, and many patients need a second agent by month 6. None of that happens well with a 15-minute annual visit.

Renal function watched, not assumed

Metformin should not be initiated at eGFR <45 and is contraindicated at eGFR <30⁶. Clara tracks eGFR every labs panel and flags if the trend is heading toward dose adjustment or discontinuation — long before your old doctor's next visit.

B12 rechecked annually

Long-term metformin is associated with reduced vitamin B12 absorption. Guidelines recommend periodic monitoring. Clara queues a B12 level annually and flags low results before they become symptomatic.

Knows when to add a GLP-1

If A1C isn't at target after 3–6 months, it's time for a second agent. Clara reads the trend and surfaces the most appropriate add-on: a GLP-1, SGLT2, or another class, based on your weight, renal, and cardiovascular context.

Common questions

Metformin questions patients actually search for.

What does Clara cost?

It's free to connect your medical records and start chatting with Clara. If you want Clara to provide medical advice, prescribe medications, or order labs, plans start at $25/month. All plans are HSA/FSA eligible. Metformin itself is a generic and typically costs $0–10/month with insurance.

Who is metformin appropriate for?

Metformin is FDA-approved for adults and pediatric patients aged 10+ with type 2 diabetes as an adjunct to diet and exercise⁶. It's also widely used off-label for prediabetes and for insulin resistance in PCOS. Clara reads your A1C trend, eGFR, LFTs, B12, and history of lactic acidosis before recommending a starting dose.

Why does metformin give some people GI side effects?

Diarrhea, nausea, and cramping are the most common side effects of immediate-release metformin, especially early in treatment. They usually improve after the first few weeks. Two things help: slow titration (start at 500 mg, step up weekly) and taking every dose with food. If tolerability remains poor, Clara may switch you to extended-release (ER), which is generally gentler on the gut.

Can I take metformin with a GLP-1 like Mounjaro or Ozempic?

Yes, and most patients should. Metformin is first-line in every T2D guideline, and adding a GLP-1 is the most common next step when A1C isn't at target. The two classes work via different mechanisms and are complementary. See Mounjaro, Ozempic, and our GLP-1s overview for specifics.

Is metformin a weight-loss drug?

No — metformin is an anti-hyperglycemic, not a weight-loss medication. It may produce modest weight loss (a few kilograms on average) as a secondary effect, but it's not FDA-approved for weight loss. If weight is your primary goal and you don't have T2D, the right conversation is about Zepbound or Wegovy, which are on-label for chronic weight management. Some DTC brands prescribe metformin as a weight-loss adjunct; Clara is transparent that that is an off-label use.

Can I take metformin with kidney issues?

Metformin should not be initiated in patients with eGFR <45 mL/min/1.73m² and is contraindicated at eGFR <30⁶. Clara reads your eGFR trend and flags early if renal function is approaching a threshold that requires dose adjustment or discontinuation.

Is Clara a real medical practice?

Yes. Clara is licensed in all 50 states. Diagnoses, prescriptions, and lab orders are reviewed and signed off by licensed physicians. Clara's AI handles intake, continuous monitoring, and follow-up; the clinical sign-off happens at the end.

How is this different from my current doctor writing the script?

Can your current doctor read your full chart, your A1C and eGFR trends, your wearable data, and your labs every time they see you? That's Clara's job. Clara refers you to an in-person clinician when a procedure or physical exam is needed — but the chart-reading, the ongoing titration, and the quarterly follow-ups happen continuously.

Can I use my insurance, HSA, or FSA?

Clara's membership is cash-pay, not billed through insurance, but every plan is HSA/FSA eligible so you can pay it with pre-tax dollars. Metformin prescriptions Clara writes go to your pharmacy and are reliably covered by insurance (typical copay $0–10/month). Ad-hoc labs Clara orders may also be covered.

What is my data used for? Is it private?

Clara is HIPAA compliant. Your records are used to personalize your care. They're not sold, and they're not used to train public AI models.

Can I use Clara for other health issues too?

Yes. One membership covers full primary care, not just diabetes. The same chat handles blood pressure, cholesterol, thyroid, annual labs, sick-day questions, and longevity work.
