What drugs cause low iron?

Several medications can contribute to low iron levels, including proton pump inhibitors (PPIs) like omeprazole, which reduce stomach acid and can impair iron absorption. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen may cause gastrointestinal bleeding, leading to iron deficiency. Additionally, certain antibiotics and antacids can interfere with iron absorption. It's essential to consult a healthcare provider if you're concerned about the effects of medications on iron levels.
