Contraindications for Deferiprone

A contraindication is a specific condition where a medication should not be used due to potential harm. It’s important to know if you have any of these conditions before starting Deferiprone.

1. Severe neutropenia: Deferiprone can lower neutrophil counts, increasing the risk of infection. If you already have low neutrophils, taking Deferiprone could worsen this condition.
2. Hypersensitivity to Deferiprone: If you’ve had an allergic reaction to Deferiprone, you should not take it again. Allergic reactions can be severe, including symptoms like rash, itching, or difficulty breathing.
3. Pregnancy: Deferiprone is not recommended during pregnancy due to potential harm to the developing baby, including birth defects (more details in the pregnancy section below).
4. Breastfeeding: Deferiprone is not recommended while breastfeeding, as it may pass into breast milk and affect the nursing infant (more details in the breastfeeding section below).

Drug to Drug Interactions with Deferiprone

Deferiprone can interact with other medications, increasing the risk of side effects or reducing its effectiveness. Always inform your healthcare provider about all medications you are taking, including over-the-counter drugs and supplements.

1. Antacids containing aluminum or magnesium: These can reduce Deferiprone absorption, making it less effective.
2. Drugs that affect the immune system: Medications like azathioprine (Imuran) or methotrexate (Trexall) may increase the risk of infection when taken with Deferiprone, as both can lower white blood cell counts.
3. NSAIDs (Nonsteroidal Anti-inflammatory Drugs): Medications like ibuprofen (Advil, Motrin) or naproxen (Aleve) may increase the risk of gastrointestinal bleeding when taken with Deferiprone.
4. Other iron chelators: Combining Deferiprone with other iron chelators like deferasirox (Exjade, Jadenu) or deferoxamine (Desferal) may increase the risk of side effects, such as liver or kidney damage.
