What is famotidine’s active ingredient?
Famotidine’s active ingredient is famotidine itself (the drug substance). Products typically list it on the label as “famotidine” along with the strength (for example, 10 mg or 20 mg), while other items on the label are non-medicinal components (excipients).
What “ingredients” besides famotidine might be in tablets or capsules?
The exact non-active ingredients depend on the manufacturer and the specific formulation (tablet vs. capsule, immediate-release vs. other types). Common categories of excipients that may appear on labels include:
- fillers or binders (to shape the tablet)
- starches or cellulose-based materials (for structure)
- lubricants (to help with manufacturing and swallowing)
- coatings (for tablets)
- capsule shell components (for capsules)
To know the precise ingredient list for a particular product, you need the label from that specific brand (or the package insert).
What ingredients are listed in “inactive ingredient” sections?
Many consumer listings and FDA-style labeling separate:
- Active ingredient: famotidine
- Inactive ingredients: excipients unique to that brand/formulation
If you share the brand name (and strength, e.g., “Pepcid AC 10 mg” or a generic NDC), I can help interpret what the label is saying.
Where can I check the exact ingredient list for a specific famotidine product?
For the most reliable “inactive ingredients” list, use:
- the package insert or carton labeling for your exact product, or
- a drug product database that matches by manufacturer/NDC.
If you tell me the brand and strength (and country), I can guide you to the exact label wording for that formulation.
