My order says 30 mg. twice a day. I am diabetic and my blood sugar goes up after I take it. My doctor is aware, he told me to adjust my Novalog to maybe an additional 5 units. I took 15 mg. this a.m. and 20 mg. this p.m. My b.s. went up very high tonight, so I am going to take only 15 mg. tomorrow. I am only to take it for 5 days.
