Eli Lilly Medical Questions
Lilly Medical provides information about the company’s prescription medicines and products.
Patients and caregivers with questions about a Lilly medication can call 1-800-545-5979.
Before contacting Lilly, have the exact product information available:
- Medication name
- Strength
- Dosage form or device type
- Lot number when relevant
- Expiration date when relevant
- Pharmacy where the medication was obtained
- Description of the question or product problem
Lilly’s product-information service does not replace the healthcare professional responsible for an individual’s diagnosis, prescription, dose, or treatment plan.
How to Report an Eli Lilly Side Effect or Adverse Event
Lilly specifically instructs customers who want to report an adverse event to call 1-800-LILLYRX.
When reporting an event, Lilly may ask for information such as:
- Name of the Lilly medicine
- When the event occurred
- Description of what happened
- How the product was being used
- Lot or device information when available
- Other information needed to investigate the report
Patients and consumers can also voluntarily report serious problems involving FDA-regulated medicines through the FDA MedWatch program.
Reporting a suspected side effect to Lilly or FDA does not determine whether the medicine caused the event. A healthcare professional should evaluate medical symptoms and treatment questions.
How to Report an Eli Lilly Product Complaint
Lilly also directs product-quality complaints to 1-800-545-5979.
Examples of product concerns can include:
- Damaged packaging
- Broken or malfunctioning injection device
- Missing component
- Product that appears damaged or altered
- Labeling or package problem
- Unexpected appearance
- Suspected product-quality issue
Before disposing of the product:
- Keep the medication or device unless its safe handling instructions require otherwise.
- Keep the carton and packaging.
- Record the lot number and expiration date.
- Keep the pharmacy receipt or prescription information.
- Take photographs if they can safely document the problem.
- Call Lilly and request product-specific instructions.
Do not mail medication, needles, injection devices, or other medical products to Lilly unless the company specifically provides return instructions.
Eli Lilly Medication Cost and Savings Help
Lilly operates savings and patient-support programs for certain medicines, but eligibility and terms differ by product.
Current Lilly programs can include:
- Commercial-insurance savings cards for eligible patients
- Coverage-support resources
- Patient enrollment programs
- Product-specific Lilly Support Services
- Pharmacy-access assistance
- Injection-training resources for selected medicines
Call 1-800-LILLYRX or use the official website for the exact prescribed medicine to determine which current programs may apply.
Savings-card terms can change and can include eligibility requirements, annual limits, insurance restrictions, expiration dates, and exclusions for certain government insurance programs.
Do not rely on an old coupon, screenshot, social-media post, or third-party website to determine current eligibility.
Eli Lilly Insurance and Pharmacy Problems
Lilly cannot control every prescription insurance decision.
When a pharmacy says a Lilly medicine is not covered or requires additional approval, determine whether the issue involves:
- Insurance formulary coverage
- Prior authorization
- Step therapy
- Quantity limits
- Pharmacy network restrictions
- Deductible or coinsurance
- Prescription expiration
- Pharmacy inventory
- Manufacturer availability
The appropriate contacts may include the prescriber, pharmacy, insurer or pharmacy-benefit manager, as well as Lilly’s product-specific support program.
Keep denial letters, pharmacy messages, prior-authorization information, and support-case numbers until the access problem is resolved.
Eli Lilly Product Availability Questions
Lilly Medical specifically directs customers who cannot find a Lilly product to call 1-800-545-5979.
A pharmacy may be unable to fill a prescription because of:
- Local inventory
- Wholesaler availability
- Product presentation or strength
- Insurance restrictions
- Prescription requirements
- Temporary supply conditions
Ask the pharmacy whether the problem involves its inventory or broader product availability before contacting Lilly. Do not substitute another strength, formulation, device, or medicine without guidance from the prescribing healthcare professional.
Eli Lilly Support for Injection Devices
Several Lilly medicines are supplied using pens, single-dose devices, vials, or other administration systems.
If a Lilly device appears damaged or does not operate as expected:
- Follow the Instructions for Use supplied with the exact product.
- Do not force or dismantle the device.
- Keep the device and packaging.
- Record the lot number and expiration date.
- Call 1-800-LILLYRX for product-specific assistance.
If a dose may have been missed, incomplete, or administered incorrectly, contact the prescribing healthcare professional or pharmacist for medical guidance rather than guessing whether another dose should be used.
Eli Lilly Products and Therapeutic Areas
Eli Lilly and Company develops and markets prescription medicines across several major therapeutic areas, including:
- Cardiometabolic health
- Oncology
- Immunology
- Neuroscience
Lilly’s current portfolio includes medicines used in areas such as diabetes, obesity, cancer, inflammatory diseases, Alzheimer’s disease, and other medical conditions.
Because prescription indications, age ranges, warnings, dosing, approvals, and availability can change, use Lilly’s current product information and FDA-approved prescribing information rather than an independent summary when making healthcare decisions.
How to Escalate an Eli Lilly Product or Support Complaint
- Identify the exact Lilly medicine, device, or support program involved.
- Call 1-800-545-5979 for a medical question, adverse event, product complaint, or product-availability concern.
- Provide the product details and problem privately.
- For a product complaint, keep the medication, device, packaging, lot information, and receipt unless instructed otherwise.
- Request and save any case or reference number.
- For insurance or pharmacy problems, document which company made the coverage or dispensing decision.
- For a medical concern, contact the prescribing healthcare professional separately.
- If the concern involves a serious product-safety problem, consumers can also submit a report to FDA MedWatch.
