What is the best way to pack diabetic supplies while traveling on an airplane?

I’m a non-insulin diabetic, although I do take injection drugs for it. Should I take the medication and needles in my carry-on, check the needles but carry the meds, or pack everything in my checked luggage?

I’m not worried about putting the meds in my checked luggage because it isn’t insulin and I will be okay (medication-wise) if my luggage gets lost.

I do have a MedicAlert card and ID that identifies me as diabetic, but no prescription label for the medication (it’s in a pen).
