Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
3-month Baseline Period occurred prior to randomization to Clinical Limit or Formulary Limit groups. 42 subjects discontinued from total enrollment of 197: (2) Adverse Event (AE), (10) Lost to Follow Up (LFU), (11) Withdrew consent, (1) Pregnancy, (16) Failed to meet Inclusion/Exclusion at Visit 4 Randomization, (2) Other

Reporting Groups
  Description
Rizatriptan 27 Tablets - Clinical Limit Eligible patients were randomized to one of two treatment regimens in a 1:1 ratio. Those randomized to receive a "clinical limit" of study medication received Rizatriptan 10mg orally disintegrating tablet (ODT): 27 tablets per month.
Rizatriptan 9 Tablets - Formulary Limit Eligible patients were randomized to one of two treatment regimens in a 1:1 ratio. Those randomized to receive a "formulary limit" of study medication received Rizatriptan 10mg orally disintegrating tablet (ODT): 9 tablets per month.
