20 mg. Great erections but after 3rd day, blood sugar went from normal(75 - 95) to 150. I was prediabetic but eating high carbs and sugar(Matt Stone 180degree health) normalized my blood glucose months ago…until going on tadalafil. That is the only change! Cannot find any information about this. All abstracts state that PDE5i improve glucose control. I’m done with taking it. I’ll miss my erections but not worth highly elevated BG. I’m the original biochemical outlier.
Tadalafil improves insulin resistance. You’re not a unicorn. All disease processes see a reduction in the action or levels of nitric oxide, Cialis enhances nitric oxide effects on the bodies tissues.
The cause of your worsening diabetes is something else. Changes in hormones can affect glucose control.

Results
Of the 68 patients who completed this study, 45 and 23 patients were allocated to the tadalafil and placebo groups, respectively. The mean HbA1c level was significantly different between the groups over the 6-month study period (P = 0.021). After 6 months of treatment, the HbA1c decrement in the tadalafil group was greater than that in the placebo group (− 0.14 ± 0.53% vs. 0.20 ± 0.69%, P = 0.030). The International Index of Erectile Function-5 scores improvement was significantly greater in the tadalafil group than in the placebo group at 6 months (P = 0.003).
