This was my error. Before I knew more I knew less. Mesochem supplied in a standard quantity of 36 g (90 x 400 mg) so I made the incorrect assumption that it was 90 days treatment, rather than 84. To be totally compliant with the guidelines we now use 84 days.
If it was me I would reserve the extra 6 to resume treatment in the (unlikely) event of recurrence. That will minimise any delay while further medication is shipped to you.
Over treating for 6 days should not cause any harm, but given the recent Gecko data the 8 weeks works well for most people we are probably overtreating by quite a bit with the 84 day course.
The trouble is we can only ever know we under treated....
