How long does Dihexa take to work?
In the first week of Dihexa, subjective cognitive shifts within days for responders. Around week 4, cycle endpoint, limited safety data on chronic use. By week 8, off-cycle. Reassess. Response varies between people, this is the commonly reported pattern, not a guarantee.
