It is generally safe to take Duphaston (dydrogesterone) and Brufen (ibuprofen) together, as there are no known harmful interactions between them. Duphaston is a hormone therapy, while Brufen is used to manage pain and inflammation. To protect your stomach, it is always a good idea to take Brufen with some food or milk. If you have any ongoing concerns or experience any discomfort, please feel free to consult your doctor.
