Nystatin Oral Suspension 100,000 units/mL — Oral Thrush Reference
Prescription nystatin oral suspension contains 100,000 units/mL for candidiasis of the oral cavity and is not a systemic-candidiasis treatment.
Prescription nystatin oral suspension indicated for candidiasis of the oral cavity; its minimal GI absorption makes it a local oral treatment rather than therapy for systemic candidiasis.

Key tradeoff: Repeated mouth dosing and local action versus systemic azole therapy.
This is a factual fit-and-tradeoff summary, not a product recommendation. Formula, device and brand claims remain manufacturer claims unless the cited source is explicitly regulatory or independent testing.
What it is
Nystatin oral suspension is a prescription polyene antifungal. The cited DailyMed formulation contains 100,000 USP units per mL and is indicated for candidiasis of the oral cavity.
Why its route matters
Nystatin is absorbed only minimally from the gastrointestinal tract. Its role is therefore local treatment in the mouth; the same pharmacology explains why the label says it should not be used to treat systemic mycoses.
How it fits into oral-thrush treatment
IDSA lists nystatin suspension as an alternative treatment for mild oropharyngeal candidiasis. More significant disease may require systemic treatment such as fluconazole.

What should make you slow down?
Prescription oral antifungal for candidiasis of the oral cavity. It is not an effective systemic-candidiasis treatment because gastrointestinal absorption is minimal. Follow the prescribed dose and course.
- Prescription medicine; use as directed by a clinician.
- Retain the suspension in the mouth as directed before swallowing.
- Not a substitute for systemic therapy when esophageal or invasive candidiasis is suspected.
