You don't necessarily need PEP. But you do need to see a professional in person to decide, not rely on this or any other forum, website, etc.
Oh gosh I was hoping not to have to take PEP I was hoping I was just over reacting !!! I feel like an idiot I was hoping that because nothing was injected and only the needle tip pierced slightly with no visible blood I would be ok! The needle tip had been exposed to air for quite a few seconds before it pricked me would that make a difference ??
Thanks
Your risk for HIV is extremely low. Sharp instrument injuries that transmit HIV (mostly in health workers) generally involve visibly contaminated (bloody) instruments and with substantial injury, not a superficial needle stick.
However, it isn't possble to say this was zero risk and it would be a good idea to see an expert ASAP to discuss PEP; some might recommend it, others probably wouldn't. I think you're also on the right track to ask the other fellow to be tested. You can do both: sometimes PEP is started (the sooner the better) then stopped after a day or two if it becomes known there was no exposure, in this case if he tests negative. If he is willing, you could go together to the doctor/clinic to discuss both PEP and testing him.
