What is indomethacin’s active ingredient?
Indomethacin is a medication whose active ingredient is indomethacin itself (the drug substance/“API”). It is sold in multiple oral and other formulations, but the common active component across brands is indomethacin.
What “ingredients” besides indomethacin might be in the tablets/capsules?
In addition to indomethacin (the active ingredient), finished products also include non-medicinal (inactive) ingredients such as fillers/binders, starches, cellulose derivatives, colorants, and film-coating components. The exact inactive ingredients vary by manufacturer and by formulation (for example, immediate-release vs. extended-release, capsules vs. suppositories).
How to check the exact indomethacin ingredient list for your specific product
To see the precise ingredient list (especially the inactive ingredients), check the packaging or the “Inactive ingredients” section of the prescribing information for your exact brand and strength, or the patient leaflet included with it.
Are there different indomethacin forms with different excipients?
Yes. Different dosage forms (tablets, capsules, suppositories, and other formulations) and different brands can use different excipients even though the active ingredient remains indomethacin.
Why inactive ingredients matter for some patients
Inactive ingredients can matter for people with allergies, sensitivities, or conditions affected by certain excipients (for example, some products use dyes or specific binders). If you share the brand name and strength (or a photo/text from the label), I can help identify what ingredients are typically listed for that specific product.
