Quick answer: Stromectol is the FDA-approved brand-name ivermectin tablet, manufactured to FDA standards and reviewed by the FDA before it reaches patients. Compounded ivermectin tablets contain the same active ingredient but are prepared by a licensed compounding pharmacy for an individual patient and are not themselves FDA-approved. Both require a prescription, and both are used to treat the same two FDA-approved indications when prescribed for that purpose.
The two products, side by side
Regulatory status. Stromectol is FDA-approved: the FDA has reviewed its safety, effectiveness, and manufacturing process for its approved indications (FDA-approved Stromectol drug label, accessdata.fda.gov). Compounded ivermectin is not FDA-approved; the FDA does not independently review a compounded product's specific safety, effectiveness, or manufacturing quality (FDA, Compounding and the FDA: Questions and Answers).
Active ingredient. Both contain ivermectin as the active ingredient. This does not change between the two products.
Manufacturing. Stromectol is manufactured at scale under FDA-regulated pharmaceutical manufacturing standards. Compounded ivermectin is prepared by a licensed compounding pharmacy for an individual patient, under a different regulatory framework than mass drug manufacturing.
Approved uses. When prescribed for an FDA-approved indication, intestinal strongyloidiasis or onchocerciasis, both products are used for the same purpose. Compounding does not expand or change what ivermectin is approved to treat; see What Is Ivermectin Used For? FDA-Approved Uses Explained.
Prescription requirement. Both require a prescription from a licensed provider under federal law in most states. Neither product changes the underlying access rules; see Is Ivermectin Over the Counter? for the current state-by-state picture.
Where each is typically available. Stromectol and its generic equivalents are typically filled through retail and mail-order pharmacies as a manufactured product. Compounded ivermectin is typically dispensed through pharmacies with compounding capability, including the compounding pharmacy infrastructure that fulfills 50 Stars Health prescriptions.
Why a patient might receive one or the other
Which product a patient receives depends on the prescribing provider and the dispensing pharmacy, not on a difference in what condition is being treated. A provider who works with a compounding pharmacy, or a patient using a telehealth service built on compounding pharmacy infrastructure, will typically receive the compounded product. A provider who sends a prescription to a standard retail pharmacy will typically result in the brand-name or generic manufactured product, subject to that pharmacy's standard substitution practices.
What does not change between the two
Regardless of which product a patient receives, a licensed provider still determines whether treatment is appropriate, prescriptions are still issued at that provider's discretion, and the approved use is still limited to intestinal strongyloidiasis and onchocerciasis. For side-effect information that applies to ivermectin generally, see Ivermectin Side Effects: What to Know Before Treatment.

Bottom line
- Stromectol is FDA-approved and manufactured to FDA-regulated standards. Compounded ivermectin is not FDA-approved and is prepared by a licensed compounding pharmacy for an individual patient.

- Both require a prescription from a licensed provider.
- Which product a patient receives depends on the prescribing provider and dispensing pharmacy, not on the condition being treated.
Frequently Asked Questions
Is compounded ivermectin as effective as Stromectol?
This page does not make an effectiveness comparison beyond what is stated on the record: both contain the same active ingredient, but only Stromectol has been independently reviewed and approved by the FDA. A licensed provider can discuss what's appropriate for your situation.
Why would a pharmacy dispense compounded ivermectin instead of Stromectol?
This depends on the prescribing provider and the pharmacy's infrastructure. Some telehealth services, including 50 Stars Health, are built on compounding pharmacy fulfillment.
Do Stromectol and compounded ivermectin treat the same conditions?
Yes, when prescribed for an FDA-approved indication. Both are used to treat intestinal strongyloidiasis or onchocerciasis. Compounding does not expand what ivermectin is approved to treat.
Is a prescription required for both Stromectol and compounded ivermectin?
Yes. Both require a prescription from a licensed provider under federal law in most states.
This page is for general educational purposes only and is not medical advice, nor a substitute for consultation with a licensed healthcare provider. Ivermectin is a prescription medication approved by the FDA to treat certain parasitic infections. It is not approved to prevent or treat viral infections or cancer. Only a licensed provider can determine whether a treatment is appropriate for you, and prescriptions are issued at the provider's discretion following a clinical evaluation. Compounded medications are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or manufacturing quality. If you believe you may have a parasitic infection, speak with a healthcare provider. Do not self-treat. In an emergency, call 911.
