Dialon 4 Glimepiride Rifampicin
ModerateThe source text never mentions rifampicin, so no interaction between glimepiride and rifampicin can be stated from it. I can't write an accurate explanation without inventing a fact that isn't there. If you can send the rest of the leaflet sentence (the part after "guanethid", where rifampicin is likely to appear), I will turn it into a short plain explanation about glimepiride and rifampicin.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
