At what interval should I take Glucophage and Femoston Mini?

At the outset, it should be noted that all the medicines mentioned in the question - Glucophage and Femoston Mini, are only available with a prescription, so please follow your doctor's instructions. So please follow the recommended dosage schedule.

As a pharmacist, I can only give you general information:
Femoston Mini may cause an increase in blood glucose levels. Thus, the current dose of Glucophage will not be effective enough. Please monitor your blood sugar regularly. Between their use, please keep a break of a few hours, at least 2-3 hours.

Glucophage: should be taken with the evening meal. https://www.gdziepolek.pl/produkty/33313/glucophage-xr-tabletki-o-przedluzonym-uwalnianiu/apteki

Femoston Mini: can be taken with or without food. Try to take your tablet at the same time each day. This keeps the concentration of the medicine in your body constant and helps you remember to take the pill every day. https://www.gdziepolek.pl/produkty/29460/femoston-mini-tabletki-powlekane/apteki
