Will ferrous sulfate interact with other medications?

Certain drugs may affect how ferrous sulfate works. Don’t take certain antibiotics two hours before or after you take ferrous sulfate; ask your pharmacist which ones. Talk with your doctor if you take any of these medicines:
  • Allopurinol (Zyloprim), a medicine used to treat gout that increases the liver’s iron levels
  • Nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Cholestyramine and Colestipol
  • Bisphosphonates, which are medicines for osteoporosis
  • ACE inhibitors, which treat high blood pressure
  • Carbidopa and Levodopa
  • Levothyroxine, a thyroid replacement hormone
  • Birth control medicines
