Finding the right Zepbound customer service number feels a bit like trying to find a specific needle in a haystack of corporate automated menus. You're likely here because you have a savings card that won’t scan, a pen that malfunctioned, or you're just trying to figure out where your next box is coming from.
Honestly, the frustration is real. When you’re dealing with a medication that’s fundamentally changing your health, the last thing you want is a "please hold" loop that lasts longer than your lunch break.

The main number you need for Eli Lilly, the manufacturer of Zepbound, is 1-800-LillyRx (1-800-545-5979). They are generally available Monday through Friday, from 9 a.m. to 5 p.m. Eastern Time.
But here’s the thing: that’s just the front door. Depending on why you’re calling, that number might just be the start of your journey.
Why a single Zepbound customer service number isn't enough
Medicine is complicated. Insurance is more complicated. Consequently, Lilly has different teams for different problems.
If you are calling because your Savings Card is getting rejected at the pharmacy—a common headache—you might actually need the specific savings support line. For those issues, people often have better luck calling 1-833-366-7157. This is the dedicated line for savings card questions and pharmacy processing errors.
If you're a patient in Canada, the rules change. You’ll want the Lilly Canada Customer Response Centre at 1-888-545-5972.
The Savings Card Drama
It happens all the time. You get to the counter, the pharmacist looks at the screen, sighs, and tells you the "system is down" or "it’s not taking the coupon."
Usually, this isn't because the card is fake. It's often a "Coordination of Benefits" error. Your pharmacist needs to know how to "secondary bill" the card. If they seem stuck, you can literally hand them the phone with the savings support team on the line.
- Primary Support: 1-800-545-5979
- Savings Card Specifics: 1-833-366-7157
- Lilly Cares (Patient Assistance): 1-800-545-6962
The Lilly Cares Foundation is a separate entity. It’s for folks who truly cannot afford the medication and meet specific low-income requirements. If you're looking for the Patient Assistance Program (PAP), don't waste time on the main clinical line. Go straight to the 6962 number.

What to do if your pen fails
Nobody likes wasting a dose. Zepbound comes in a single-dose autoinjector. Sometimes, they misfire. Maybe the needle didn't retract, or the liquid sprayed across the room instead of into your thigh.
Do not throw the pen away.
Basically, Eli Lilly needs that pen back to investigate what went wrong. When you call the Zepbound customer service number at 1-800-545-5979 to report a "product quality complaint," they will ask for the Lot Number. This is printed on the side of the pen and the box.
They might send you a "return kit" which is a fancy way of saying a padded envelope to mail them the broken pen. Often, if they determine the pen was at fault, they’ll send a voucher to your pharmacy for a replacement box.
It takes time. It won't happen overnight.
Side Effects and Medical Questions
If you’re experiencing a medical emergency, call 911. Don't call a pharmaceutical company.
However, if you want to report a side effect (an "adverse event" in industry speak), Lilly is legally required to take that report. You can use the main 1-800-LillyRx number for this. You can also report side effects directly to the FDA MedWatch program at 1-800-FDA-1088.
The LillyDirect Factor
In 2024 and 2025, Lilly pushed hard into "LillyDirect," their direct-to-consumer delivery service. If your prescription is being handled through LillyDirect, you aren't actually dealing with Lilly's corporate office for shipping—you're dealing with their third-party pharmacy partners like Truepill or Eversana.
If your package is lost in the mail or your ice packs melted, calling the corporate Zepbound customer service number will just result in them transferring you.
Instead, check your confirmation email. Most LillyDirect orders are currently managed through a separate portal with its own support staff.
Pro Tips for Calling
- Morning is better. Call right when they open at 9 a.m. ET. Tuesday through Thursday are usually quieter than Mondays.
- Have your box ready. They will ask for the NDC number (the barcode number) and the Lot Number.
- Note the Case Number. If they open a "case" for you, write that number down. If you have to call back, it saves you 15 minutes of re-explaining your life story.
- Pharmacist on standby. If it's a billing issue, try to call while you are actually at the pharmacy or have your pharmacist’s direct line ready.
Dealing with big pharma is rarely "fun." It’s a lot of bureaucracy. But knowing which specific number to dial can save you about three hours of hold music.
If the phone lines are slammed, Lilly also has a "Submit a Question" form on their official website. It’s slower, but it creates a paper trail, which is sometimes better for insurance appeals.
To get moving, check your current Zepbound box for the Lot Number right now. Save the 1-800-545-5979 number into your contacts as "Lilly Support" so you aren't scrambling the next time the pharmacy system decides to act up. If the issue is strictly about the cost, call the savings line at 1-833-366-7157 first to verify your card is active.
