I was taking a 200mg tablet once per week for a fingernail fungus. My blood sugar levels which are always under 130 (I'm very careful), went up 150, 160. 185. I stopped medication and my blood glucose is back under 130.
That's interesting. I can't find anything that it does that, however that doesn't mean it wasn't doing it to you.
I know it's been years since you wrote this but I just searched for the same information and nothing confirms that fluconazole raises blood levels... except you, another consumer like me.
I am in the midst of taking 100 mg each day for a week. My blood sugar has risen about 20 pts to numbers I've never seen.
I won't be able to fully test this theory out until I finish the medication and find out if my numbers go back down. I wanted to be sure to validate your question. Even if you don't come back to read what I've said, maybe others will feel there is reason to suspect their rise in blood sugar both before and after taking fluconazole, which is a generic for Diflucan.
Real numbers are important for your doctor so be sure to keep records. I usually test my fasting blood sugar each morning before drinking (or eating) anything... well, except water, that is.
I took the 3 day 150mg course and I had blood work done while still on the drug. My glucose level was elevated as well. This drug can affect the adrenal glands function which control the metabolic functions of the liver related to the cortisol production.
My wife's blood glucose levels have always been a bit borederline, though she has never been pronounced to be diabetic. Several months ago she was diagnosed with stage 4 ovarian cancer. This does seem to be responding to chemotherapy, but obviously what is happening in her body is quite complex due to chemotherapy, various other drugs, and the cancer itself. A few weeks ago she developed oral thrush which didn't respond to Nystatin, and she has been taking Fluconazole daily for several weeks. Her blood sugar levels have risen significantly, but we won't be able to tell if this is due to the Fluconazole until after she stops taking the medication.
