Are there generic versions of Intuniv (guanfacine ER) yet?
Yes. Intuniv is an extended-release form of guanfacine, and generic equivalents are generally available as patents/exclusivity expire and as manufacturers obtain approval. The key is confirming you’re comparing the same formulation (extended-release) and strength.
What counts as a “generic for Intuniv”?
A true generic substitute for Intuniv is typically labeled as guanfacine hydrochloride extended-release (ER) and comes in the same extended-release dosing style used for Intuniv. Regular (immediate-release) guanfacine is not interchangeable in the same way because the release profile differs.
How to make sure the pharmacy gives the right version
When you fill a prescription, check the label for:
- “guanfacine” plus “extended-release” (ER)
- the dose (for example, 1 mg, 2 mg, 3 mg, or 4 mg—whatever matches your prescription)
- that it’s the ER product, not an immediate-release formulation
If you tell me your Intuniv dose and whether you’re in the US (or another country), I can help you figure out what the matching generic wording usually looks like.
