For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Hemin is used to treat acute porphyria attacks, and glucocorticoids may induce hepatic ALA synthase, counteracting the heme-mediated suppression. This could reduce the benefit of hemin.
What this interaction means in plain words
Dexamethasone and Hemin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Dexamethasone belongs to Endocrine; Hemin belongs to Miscellaneous.
Why it happens
Corticosteroids can induce delta-aminolevulinic acid synthase, opposing hemin's feedback inhibition of porphyrin synthesis.
What to do
Avoid dexamethasone in acute porphyria unless essential, and monitor porphyrin precursors and clinical response to hemin.
What to ask your pharmacist

- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
