Yes, it is okay for people who inject drugs to use injectable PrEP (like CAB-LA) to protect themselves against HIV that may be transmitted during sex. However, we do not yet know if it also protects against HIV from sharing needles or injecting drugs. While research continues, healthcare providers should offer PrEP together with other support services for people who inject drugs. This way, they can still benefit from the protection of PrEP against sexual HIV transmission while staying informed about its limitations for needle use.
