Back to Guanfacine (Intuniv)

Daily-use question

Can I take Guanfacine (Intuniv) every day?

Daily use is reasonable for most users — cycle if effect attenuates. Guanfacine (Intuniv) can be used daily by most healthy adults at standard doses. Watch for tolerance signs — diminishing subjective effect at the same dose — and either cycle off (1 week per quarter) or rotate compounds within the same goal.
