Criteria

Inclusion Criteria:

• The patient should have participated in an ongoing placebo-controlled trial regarding the effect of paroxetine in PMD; to be included in that trial, she must have fulfilled the diagnostic criteria A-C of PMDD in DSM-IV and certain other inclusion and exclusion criteria which are listed in appendix 1.

• The patient should a) have been given paroxetine during the previous trial, b) have reported that she has been "much improved" or "very much improved" by this treatment, c) have displayed a marked reduction in VAS-rated irritability during treatment, and d) have reported that she has found the side-effects tolerable.

• The patient should display at least a 50% increase in VAS-rated irritability during the luteal phase (mean of last five days prior to menses) as compared the follicular phase (days 6-10) during one cycle of pretreatment symptom rating (without medication).

• The patient should have given written informed consent to participate in the study.

Exclusion Criteria:

• Any concomitant psychiatric disorder for which SRIs are known to be effective.

• Any other concomitant psychiatric disorder that, in the investigator's opinion, would render the patient unsuitable for the study.

• Any somatic disorder that, in the investigator's opinion, would render the patient unsuitable for the study.

• Any ongoing medication which, in the opinion of the investigator, would render the patient unsuitable for the study. Examples of medications that preclude participation in the study are: 1) any psychotropic drug, with the exception of the occasional use of hypnotics, 2) any hormonal preparation, with the exception of thyroid hormone, 3) anti-coagulants, and 4) 5HT1D agonists. Occasional use of analgesic compounds does not preclude participation.

• Patient characteristics which, in the opinion of the investigator, are likely to reduce compliance with the protocol.
