keith mixtard is a fixed combination insulin
. 30 % of regular or short acting and 70% is a long acting insulin combination . short acting will take care of your breakfast and long acting for your lunch and upto night . so you have to take twice daily . before bf and before dinner. dosage depends on your sugar level. so you have to check your fasting , pre lunch , pre dinner and depending on that you have to adjust. but only thing is you can not increase that you can not increase or decrease one part of that insulin. but nothing wrong in using this . 50 / 50 means 50% short acting and 50% long acting . this is given when when your post break fast sugar is not well controlled but your post lunch is well controlled.
so its just a premixed insulin of both short acting and long acting insulin
hope u got it. keeep in touch bye
