I currently take Metformin 500mg twice a day, plus Perindopril 8mg to manage hypertension. The recommendation is to take Perindopril half an hour before a meal, and Metformin with food. Now, I'd like to follow the instructions to the letter, but either my life seems too haphazard or I'm just not very organised, so I take them both together, either half an hour before a meal or with my food. Does it matter?
