Summary
Corticosteroids raise blood glucose and counteract pioglitazone. Dexamethasone may also lower pioglitazone exposure via CYP3A4 induction, but the net effect with topical use is small.
What this interaction means in plain words
Dexamethasone-tobramycin and Pioglitazone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Dexamethasone-tobramycin belongs to Anti Bacterial; Pioglitazone belongs to Endocrine.
Why it happens
Glucocorticoid-induced insulin resistance opposes pioglitazone, and CYP3A4 induction may modestly increase its clearance.

Monitor blood glucose during systemic corticosteroid courses and adjust diabetes therapy if control worsens.
