FDA Updated OTC alli Label: Ask First If You’ve Had Kidney Disease

Quick takeaway: If you’ve ever had kidney disease or kidney stones, FDA now says you should ask a health care provider before using the OTC weight-loss drug alli (orlistat 60 mg).

FDA also added “stop and contact a doctor” guidance: The updated alli label tells people to stop using alli and contact a doctor if they develop kidney-injury or kidney-stone symptoms listed on the label.

What the FDA updated on June 10, 2026

On June 10, 2026, FDA approved changes to the Drugs Facts label for OTC alli (orlistat 60 mg). The FDA update adds clearer warnings about a rare risk of acute kidney injury and highlights the importance of knowing your kidney history before using orlistat.

FDA’s safety communication explains the label update reflects postmarketing safety information and biological plausibility related to kidney injury and kidney stone concerns (including reports involving oxalate-related findings).

Who should check first (before taking alli)?

According to the updated alli label, check with a health care provider before using alli if you have ever had:

Kidney disease
Kidney stones

This is important because some kidney conditions can be undetected until kidney function is checked with testing.

Symptoms that should make you stop alli and contact a doctor

The label lists kidney-injury or kidney-stone symptom categories. If any of the following happen, the label instructs you to stop using alli and contact a doctor:

Back or groin pain
Painful urination
Blood in the urine
Swelling of the feet and legs
Less frequent urination

If symptoms are severe, rapidly worsening, or you suspect a medical emergency, seek urgent/emergency care right away.

Background: kidney problems can be hard to spot

Chronic kidney disease (CKD) often progresses without obvious early symptoms. The CDC notes that blood and urine tests are needed to check for CKD.

Kidney stones also vary by person, but kidney-stone education resources describe common patterns like pain (often in the back) and blood in the urine—patterns that help readers understand why the alli label highlights specific kidney-related symptoms. (These are general patterns, not a diagnosis.)

What we know—and what we don’t

This FDA label change is based on postmarketing safety information. FDA’s action is intended to improve consumer safety by adding clear “ask first” and “stop and contact a doctor” instructions for relevant histories and symptoms.

Evidence describing orlistat-associated kidney injury includes case-report information. Case reports can show that an event is possible, but they cannot tell you the exact risk for every individual patient.

What to do today

Check your kidney history: If you’ve ever had kidney disease or kidney stones, talk with a health care provider before using alli.
Know the label’s warning symptoms: If you develop any of the label-listed kidney-injury/kidney-stone symptom categories, stop using alli and contact a doctor.
Use the medication label: Review the Drugs Facts information and consider sharing a medication list with your clinician—especially if you have any kidney risk factors.
