Orlistat 120 mg and Xenical: Prescription Product Research

Orlistat is a lipase inhibitor used in weight-management products. In the United States, the strength and product matter: orlistat 120 mg is a prescription product, while alli contains orlistat 60 mg and is sold as an over-the-counter weight-loss aid for adults under its current FDA-approved labeling.

This page belongs to Valencia Town Center Pharmacy’s broader metabolic medication research section. Orlistat should not be described as a Type 2 diabetes drug. It is a weight-management medication with a different mechanism, product history, and regulatory status from diabetes medicines such as metformin, sitagliptin, or semaglutide products.

Xenical and prescription orlistat 120 mg

Xenical is the branded 120 mg orlistat capsule. Current DailyMed labeling identifies Xenical as a human prescription drug under NDA 020766. The label lists each capsule as containing 120 mg of orlistat and identifies the product as Rx only.

The current label describes Xenical as a reversible inhibitor of gastrointestinal lipases for obesity management, including weight loss and weight maintenance, when used with a reduced-calorie diet. The same active ingredient also appears in a 120 mg authorized generic label under the same NDA. DailyMed identifies that product as “ORLISTAT” 120 mg and classifies its marketing category as “NDA authorized generic.”

An authorized generic is not the same regulatory pathway as a separate ANDA generic. It is a product marketed under the brand product’s approved NDA without the brand name on the label. That distinction is useful when a patient is comparing a bottle labeled simply “orlistat” with a Xenical-branded bottle.

Why 120 mg prescription orlistat is not the same as OTC orlistat

The lower-strength OTC product alli contains 60 mg of orlistat per capsule. Current DailyMed labeling classifies alli as a human OTC drug, and FDA describes it as a nonprescription weight-loss aid for overweight adults 18 years and older when used with a reduced-calorie, low-fat diet.

FDA’s June 10, 2026 Drug Safety Communication also explicitly distinguishes the two categories: alli 60 mg is OTC, while the higher-strength Xenical 120 mg product is available by prescription.

That means a search result for “orlistat” is incomplete unless it identifies the exact strength and product. A 60 mg OTC capsule and a 120 mg prescription capsule should not be treated as interchangeable versions of one retail item.

Product details to verify

For a prescription written for orlistat 120 mg or Xenical, useful details include:

  • active ingredient: orlistat;
  • strength: 120 mg per capsule;
  • dosage form: oral capsule;
  • whether the product is Xenical or an authorized-generic orlistat product;
  • the labeler/distributor and NDC on the dispensed package;
  • prescription status;
  • whether the payer covers the prescribed product or treats weight-management medications under a separate benefit rule.

The current Xenical label identifies CHEPLAPHARM as the licensor and H2-Pharma as the U.S. distributor on the representative package labeling. Current product labeling can change, so the actual bottle and current DailyMed record are more reliable than an old marketplace image.

Cost and coverage questions

Weight-management medication coverage varies widely among plans. Even when two products contain the same active ingredient, coverage can differ by strength, branded versus authorized-generic status, plan exclusions, prior authorization criteria, or pharmacy network.

Before obtaining a 120 mg prescription product, a patient may want to verify:

  • whether the prescription specifies Xenical or allows an orlistat product;
  • whether the plan covers prescription weight-management drugs;
  • whether prior authorization or another coverage step is required;
  • whether the pharmacy can obtain the exact 120 mg product if it is not currently on hand;
  • whether a quoted price is for 120 mg prescription capsules rather than 60 mg OTC alli.

Safety and labeling differences matter

Orlistat reduces absorption of dietary fat in the gastrointestinal tract. Its labeling includes gastrointestinal adverse effects and important warnings and interaction considerations. FDA updated OTC alli labeling in 2026 to add kidney-stone and kidney-injury warnings, aligning the renal-risk warning across FDA-approved orlistat products.

Because orlistat can affect absorption of some medicines and fat-soluble vitamins, product selection should not be reduced to “120 mg is stronger than 60 mg.” The prescription product and OTC product have different labeling, intended-use instructions, and regulatory status.
