Ozempic vs Tirzepatide: What Switching Really Costs in 2026

Find the line that matches how you pay today.

• Lowest cash price: compounded tirzepatide at Arbor, about $150 a month on a prepaid year. It is mixed by a pharmacy and not FDA-approved.
• FDA-approved, paying cash: Zepbound from LillyDirect or a local pharmacy, about $300 to $450 a month by dose.
• Insured with type 2 diabetes: keep Ozempic on its savings card, or ask your plan whether it covers Mounjaro. Either card can bring a fill down to $25.
• On Medicare: the GLP-1 Bridge charges $50 a month for the Zepbound KwikPen if you qualify. It does not cover Ozempic, and it excludes people with type 2 diabetes.
• Both brands from one clinician: Ro, our pick, prescribes branded Ozempic and Zepbound and helps with insurance.

Tirzepatide vs Ozempic cost, by way to pay

The table shows the monthly price you would actually pay. Here is what sits behind each line, starting with the programs that can prescribe.

Ro: Ozempic and Zepbound from the same clinician

Ro Body prescribes branded GLP-1 drugs only, with nothing compounded. Its site names both Ozempic and Zepbound. That makes it the simplest place to ask whether a switch makes sense for you.

• Zepbound: about $300 at 2.5 mg, about $400 at 5 mg, about $450 from 7.5 mg, at Lilly's own cash prices.
• Membership: about $150 a month, about $40 the first month. About $75 a month if you prepay a year, about $890 upfront.
• Ozempic: mainly an insurance route. Ro checks your coverage, and its membership is cash only.

Ro says plainly that Ozempic is not FDA-approved for weight loss. Its clinicians may still prescribe it for weight loss, outside its label. Without coverage, Ro quotes Ozempic at list price, so Novo Nordisk's own self-pay pharmacy costs less.

A first year of Zepbound at Ro costs about $5,600 to $6,100 with the yearly prepay. Month to month, it reaches about $6,870. The program is not offered in Hawaii, Louisiana, Mississippi or Virginia. It offers no hormone therapy. Trustpilot, a public review site, rates it 3.9 out of 5 on about 6,800 reviews. Our Ro review covers the rest.

Arbor: the lowest tirzepatide price, if you prepay a year

Arbor sells compounded tirzepatide at one price for every dose, with no membership. The low price needs a full year paid at once.

• 12-month plan: about $150 a month, paid upfront as about $1,790.
• 6 months: about $170 a month · 3 months: about $190 · Month to month: about $250.
• Included: clinician visits through MD Integrations, check-ins, shipping and a dietitian.

Two conditions matter if you are coming off Ozempic. Once a prescription is written, nothing is refunded, unshipped months included. Its 12-month money-back guarantee also excludes anyone who took a weight-loss drug in the year before joining. Arbor does not name its pharmacies. Trustpilot rates it 4.5 out of 5, on only 51 reviews under its old Harbor name.

Gala: compounded tirzepatide and hormone therapy on one account

Gala is built around women in midlife. Compounded tirzepatide costs about $180 a month on the yearly plan and about $200 on the 3-month plan. Every dose, dose changes and shipping are included.

Gala also sells brand-name Ozempic, from about $1,300 a month. That is far above Novo Nordisk's own self-pay price, so it is not the way to buy Ozempic. The reservations are real. Its terms refund nothing if you cancel. The pharmacy is not named. The Better Business Bureau gives Gala a C-, with billing complaints. Trustpilot rates it 4.6 out of 5 on about 4,200 reviews. Our Gala review has the detail.

Zepbound self-pay: FDA-approved tirzepatide at a cash price

Eli Lilly sells Zepbound to people paying cash. The KwikPen holds four weekly doses, and each vial holds one. A month of either costs the same.

• 2.5 mg: about $300 a month.
• 5 mg: about $400 a month.
• 7.5 mg to 15 mg: about $450 a month if you refill within 45 days.

The 45-day clock is the catch. Refill late and a fill costs about $500 at 7.5 mg. At 10 mg and above, a late fill costs about $700. Since March 16, 2026, major pharmacies also fill the KwikPen at the self-pay price. The vial stays a LillyDirect product. Our Zepbound cost page tracks every channel.

Ozempic pen self-pay: the price if you stay on Ozempic

Novo Nordisk sells the Ozempic pen through NovoCare Pharmacy and its self-pay offer. New patients pay about $200 for each of their first two monthly fills at 0.25 or 0.5 mg. That intro offer runs through December 31, 2026.

After that, the pen costs about $350 a month at doses up to 1 mg. At 2 mg, it costs about $500. Novo says the money spent does not count toward your insurance deductible. Our Ozempic cost page lists the other ways to pay.

Ozempic pill: the cheapest brand-name Ozempic

Since May 4, 2026, the tablet once sold as Rybelsus has been sold as the Ozempic pill. It is a daily tablet, approved for type 2 diabetes like the pen. Self-pay starts at about $150 a month at 1.5 mg. It costs about $200 at 4 mg and about $300 at 9 mg.

No tirzepatide pill is FDA-approved. So if you want a brand-name drug without a needle, staying on semaglutide is the only route here.

Savings cards with insurance and type 2 diabetes

Both makers run copay cards for people with commercial insurance, the kind you get through work or buy yourself. Each card needs a prescription for an FDA-approved use, which means type 2 diabetes for both drugs.

• Ozempic card: pay as little as $25. The card pays at most $100 per 1-month fill, $200 per 2-month fill or $300 per 3-month fill.
• Mounjaro card: pay as little as $25 for up to a 3-month fill. It pays at most $150 a month and $1,950 a year. This card expires December 31, 2026.
• Mounjaro without coverage: if your commercial plan does not cover Mounjaro, the same card brings a 1-month fill to as low as $499.

Read the cap, not just the $25. If your copay is $300, the Ozempic card takes off $100 and you pay $200. A plan with a high deductible can use up the Mounjaro card's yearly cap before December.

Mounjaro has no cash program for people with no insurance at all. With a GoodRx coupon, it still costs about $1,060 to $1,090 a month at most pharmacies. Our Mounjaro savings page explains that card in full.

Medicare GLP-1 Bridge: $50 a month for the Zepbound KwikPen

Since July 1, 2026, Medicare's GLP-1 Bridge has let eligible people with Part D, Medicare's drug coverage, get certain weight-loss drugs for $50 a month. It covers the Zepbound KwikPen, Wegovy and Foundayo, Lilly's weight-loss pill. Zepbound vials and single-dose pens are not included.

Ozempic and Mounjaro are not on the list. People with type 2 diabetes, moderate to severe sleep apnea or fatty liver disease cannot join, and neither can anyone already getting a GLP-1 through Part D. You also need to meet a BMI threshold. Your prescriber sends a prior authorization, meaning Medicare's approval before it pays, and it holds through December 31, 2027.

Will I lose more on tirzepatide? What the head-to-head trial found

The best answer comes from SURMOUNT-5, published in 2025. It enrolled 751 adults with obesity and without type 2 diabetes for 72 weeks. Weight fell by 20.2% on tirzepatide and 13.7% on semaglutide. The trial had no placebo group, so it compares the two drugs only against each other. Its semaglutide group took up to 2.4 mg, a Wegovy dose above Ozempic's 2 mg ceiling, so it was not an Ozempic trial.

Those are averages, not a promise for any one person. Our semaglutide vs tirzepatide comparison covers the trial, how the drugs differ and their side effects.

Already on Ozempic: is switching to tirzepatide worth the money?

A switch restarts your dose ladder, and the price follows it. Here is a first year paid in cash, following the label's dose steps. Each line counts 12 monthly fills.

• Stay on the Ozempic pen at 1 mg: about $4,190 for the year.
• Stay on the Ozempic pen at 2 mg: about $5,990.
• Switch to Zepbound and stop at 5 mg: about $4,690, starting with one month at 2.5 mg.
• Switch to Zepbound and reach 7.5 mg in month three: about $5,190, refilling on time.
• Switch to compounded tirzepatide: about $1,790 at Arbor, prepaid, or about $2,150 on Gala's yearly plan.

So the answer depends on your Ozempic dose. From 1 mg, a switch to Zepbound costs about $500 to $1,000 more in year one. From 2 mg, it saves about $800 to $1,300. Compounded tirzepatide saves the most, but it is not an FDA-approved drug.

Offered Ozempic but not started yet? The intro price changes the math. A new patient's first year runs about $3,890 if she stays at or below 1 mg. Reaching 2 mg in month four brings it to about $5,240. Each fill covers about four weeks, so a full 52 weeks can need a 13th fill on either drug.

What a switch does to your savings card, insurance and Medicare

Your Ozempic coverage does not carry over to tirzepatide. Each drug brings its own rules.

• Savings card: the Ozempic card stops being useful. Mounjaro has its own card with the same type 2 diabetes condition. Zepbound's card needs a commercial plan that covers Zepbound.
• Zepbound card terms: pay as little as $25 for a 1- to 3-month fill. It pays at most $100, $200 or $300 per fill and $1,300 a year, and it expires December 31, 2026.
• Prior authorization: a new drug usually means your plan reviews the request again before it pays.
• Medicare with type 2 diabetes: Ozempic and Mounjaro stay under your Part D plan's normal coverage. Part D caps your yearly drug spending at $2,100 in 2026. The Bridge is closed to you.
• Medicare without diabetes: Part D does not cover Ozempic for weight loss. The Bridge can bring the Zepbound KwikPen to $50 a month if you qualify.

Check your plan's drug list before you ask for a switch. Our pages on Ozempic savings, Zepbound savings and tirzepatide insurance coverage go through each rule.

Brand Zepbound or Mounjaro, or compounded tirzepatide?

Zepbound and Mounjaro are the same molecule with different FDA labels. Zepbound is approved for weight management and for sleep apnea in adults with obesity. Mounjaro, like Ozempic, is a diabetes drug. Our Mounjaro vs Ozempic page covers that pairing, and Ozempic vs Zepbound covers the weight-loss label.

Compounded tirzepatide is mixed by a pharmacy and is not FDA-approved. Since the shortage ended in December 2024, it is legal only on a narrow one-patient basis. On April 30, 2026, the FDA proposed not to add semaglutide, tirzepatide and liraglutide to its 503B bulks list. That list governs large outsourcing facilities only. Comments closed July 30, 2026, and there is no final decision yet. Our guide to compounded tirzepatide explains the legal side.

Which online programs sell Ozempic, and which sell tirzepatide

Most cash-pay programs sell compounded tirzepatide, not brand-name Ozempic. Here is what each source on this page names on its own site.

• Ro: brand-name Ozempic and Zepbound, plus Wegovy and Foundayo. Nothing compounded.
• Gala: compounded tirzepatide and brand-name Ozempic. Its Ozempic page does not mention Zepbound or Mounjaro.
• Arbor: compounded tirzepatide and compounded semaglutide only. No brand-name Ozempic.
• LillyDirect: Lilly's own pharmacy for Zepbound, with the KwikPen also at major pharmacies.
• NovoCare Pharmacy: Novo Nordisk's own pharmacy for the Ozempic pen and pill at self-pay prices.

How the switch from Ozempic to tirzepatide works in practice

There is no dose that matches your Ozempic dose. A 2026 clinical review for pharmacists in The Pharmaceutical Journal says no validated dose equivalence exists between the two drugs. The tirzepatide label starts everyone at 2.5 mg, whatever Ozempic dose you were on.

Your prescriber sets the timing of your first tirzepatide dose.

The restart has a price effect too. Your first Zepbound month is the cheapest fill, and the 45-day refill clock starts with it. Our tirzepatide dosage chart shows each step and how soon it can come.

Switching at 45, with shifting hormones

One label detail matters in your forties. Tirzepatide's label advises anyone on birth control pills to switch to a non-oral method or add a barrier method. That applies for 4 weeks after starting and 4 weeks after each dose increase. Pregnancy is still possible in perimenopause, so plan this before your first dose.

Lilly also says there are no data on tirzepatide with oral hormone therapy, because it has not been studied. If you take estradiol by mouth, a clinician who handles both is useful. If you have moderate to severe sleep apnea with obesity, Zepbound carries an FDA approval for that too.

Ozempic or tirzepatide: stay or switch, by profile

• On Ozempic 2 mg, paying cash: switching to Zepbound costs less from 7.5 mg up, even after the restart. It saves about $800 to $1,300 in year one.
• On Ozempic 1 mg or less, paying cash: staying is cheaper. Switch for a medical reason, not for the price.
• Insured, with type 2 diabetes: stay unless your plan covers Mounjaro. The Mounjaro card's yearly cap and end date are worth checking first.
• On Medicare, with type 2 diabetes: stay within Part D. The Bridge is not open to you.
• On Medicare, without diabetes: the Bridge's $50 Zepbound KwikPen beats any cash price, if you meet its criteria.
• Lowest cash price: compounded tirzepatide, accepting that it is not FDA-approved and that these plans are rarely refunded.
• Not sure yet: a program like Ro can review both options with your insurance in one visit.
