I have been on glicazide for 8 years now, and it suits me. I started on max dose (320mg/day) and it initially did not work because I had very high insulin resistance. I went onto a low carb diet (LCHF) and very soon I found I was having ro reduce my dose to avoid hypo;s. The hypo;s when they occurred were quite gentle and short lived so not a problem, but is a noted side effect. I had no other side effects and for me it has worked well. I am still lowish carb diet but not keto. i find it can drop my bgl by abour 3 mmol/l even at just 40mg minimum dose, so I use it to allow me to eat a higher catb meal without worry,
If you are a driver then you can talk to your GP about getting a meter since this drug can causd hypos and they should support you with test strips. Mine does. But you need to have some evidence of reaching near hypo levels. I privately funded for a short while and got some impressive graphs to back me up.
gliclazide is a second generation sulfonyl drug, and does not suffer from the supposed beta cell burnout that the original ones were reputed. Studies have shown long term use does not thrash the pancreas.
Some stuudies show that this drug has benefits in terms of cardio care and has other benefits other than just blood sugar levels. Since going onto the Glic, all my HbA1c results are below 48. I started 8 years ago at 106 so the diet + med combination has been effective for me.
