Some medications are only a problem at certain dosages or intervals.[ref] Primaquine, an anti-malaria drug, is linked to a dose-dependent risk of hemolytic anemia in people with G6PD deficiency.[ref] Other drugs that cause Predictable or Possible hemolysis include:[ref] Drugs that cause predictable hemolysis: Dapsone Primaquine Methylene Blue Cotrimoxazole Sulfadiazine Quinolones (ciprofloxacin, ofloxacin, nalidixic acid) Nitrofurantoin Rasburicase Toluidine blue Drugs causing possible hemolysis: Chloroquine Quinine high dose aspirin, acetaminophen Sulfasalazine Chloramphenicol Isoniazid Ascorbic acid (very high doses[ref]) Glibenclamide Vitamin K Isosorbide Dinitrate What about hydroxychloroquine
The vast majority of patients feel fine and benefit from the injection without any problems
Some of them have heavy metals
Unopened vials: Store at controlled room temperature (20-25 degrees C / 68-77 degrees F) Protected from light in original packaging Good until manufacturer-printed expiration date (typically 18-24 months from production) Do not freeze freezing can compromise the glass vial seal and alter preservative distribution After first puncture: Refrigerate at 2-8 degrees C (36-46 degrees F) 28-day use window from first needle puncture per Pfizer/Hospira prescribing information Swab the rubber stopper with 70% isopropyl alcohol before every puncture Label the vial with the first-puncture date Discard after 28 days regardless of remaining volume or visual appearance What shortens the 28-day window: Room-temperature storage after puncture (can reduce effective window to 7-10 days) Excessive puncture count (30+ punctures accelerate preservative depletion) Poor aseptic technique (skipping alcohol swabs introduces surface contamination) Temperature cycling (moving between fridge and room temp repeatedly) For a deep dive on shelf life, degradation signs, and the science behind the 28-day rule, see How Long Does Bac Water Last After Opening
