The Biggs article includes the Daily Record Scale which is use in treatment studies.
All sources comment the mechanism of RX is specific to the SSRI as opposed to antidepressants and cite a) immediate clinical effect in PMDD b) lack of effect from non-SRI antidepressants.
Occasional use of the SSRI (ie symptoms onset ) as opposed to daily use is simply to minimize side effect.
The issue of increasing the dose temporarily for patients already on SSRI I did not see addressed.
