Which cleansing agent should be used to clean needles and syringes between intravenous drug users (IDUs)?

Using bleach as a cleansing agent for needles and syringes between intravenous drug users is grounded in its effectiveness as a disinfectant. Bleach is a strong antimicrobial agent that can kill a wide range of pathogens, including viruses and bacteria associated with bloodborne infections, such as HIV and hepatitis.

The recommended procedure involves using a bleach solution to soak the syringe and needle, followed by rinsing with water. This process helps to reduce the risk of transmission of infectious diseases among IDUs, as it significantly lowers the viral load that can be present on shared equipment.

In contrast, hot water is not effective alone in eliminating all pathogens; ammonia is not recommended for such purposes in medical contexts due to its potential harmful effects and ineffectiveness against certain viruses, while rubbing alcohol, while a good disinfectant for skin and surfaces, is less effective in this specific context compared to bleach for cleaning needles and syringes. The critical aim is to ensure that cleaning agents used can adequately address the types of contaminants present in shared injection equipment, with bleach being the most reliable option.
