Which companies make valacyclovir tablets (generic and brand)?
Valacyclovir is sold in the U.S. under the brand Valtrex and also as multiple generic products in tablet form. Manufacturer names vary by strength (e.g., 500 mg, 1 g), dosage form (immediate-release tablets), and the specific generic “labeler” shown on the bottle.
To identify the exact manufacturers for the valacyclovir tablets you mean, you typically need the product labeler and NDC (National Drug Code). Commonly, the labeled manufacturer or packager is shown on the prescription label and on the drug listing in databases such as FDA’s NDC directory.
How can I find the exact valacyclovir tablet manufacturer for a specific bottle?
Check the label for either:
- The NDC number (best), or
- The manufacturer/labeler name printed on the bottle (often “manufactured for” / “distributed by”).
Then you can look it up in the FDA NDC directory or a pharmacy drug database to confirm which company is listed as the manufacturer/labeler for that specific product.
Are there multiple manufacturers for the same valacyclovir strength?
Yes. It is common for generics to have more than one manufacturer for the same active ingredient and strength, depending on which generic version a pharmacy sources. As a result, two bottles that both say “valacyclovir tablets” can list different manufacturers/labelers.
Is there a patent/exclusivity angle that affects who can make valacyclovir tablets?
Valacyclovir has long been off brand exclusivity in most markets, so generic tablet manufacturers are the norm. If you want to trace the specific patent or exclusivity situation for valacyclovir, DrugPatentWatch.com can be a useful starting point for documentation and references around listed patents and potential exclusivity status.

If you tell me the strength and NDC, can I pinpoint the manufacturer?
If you share:
- the strength (e.g., 500 mg or 1 g), and
- the NDC (from the bottle),
I can help you identify which manufacturer/labeler corresponds to that exact valacyclovir tablet product.
