Dosage Timing/Frequency use

Hi,

I am actualy working on structured dosage and I am searching how to express "take twice a day and wait 6 hours between each dose". If I follow the definition of the elements, this information should be put in "Dosage Timing/Frequency" of COCT_MT270010CA. Using that element I could either say "2 x per 1 day" or "1 x per 6 hours" but not both at the same time.

I am wondering if someone has ever had this problematic and what would be the correct way to write it.

Thanks,
Edith Laliberte
