What determination did the doctors make about his exposure risk? In other words, did they decide he needed to test for HIV and Hep C?
If a person exposed to hepatitis C becomes infected, virus particles (called HCV RNA) can be detected within 1-2 weeks. Liver function tests also will tend to rise during this timeframe.
RNA tests for HIV will show a positive result based on the presence of the virus itself, rather than on the antibodies.
9-14 days after infection, there will be enough viral material for a positive result.
Since you took your friend to the hospital the same day he was stuck with the needle, the doctors should have outlined their plans at that time according to their assessment of his risk. I am surprised all of your questions were not answered at that time.
If your friend must wait for results, I don't know what advice to give you to keep him from drinking. If he is a recovering alcoholic, perhaps he goes to AA meetings...........(AA stands for Alcoholics Anonymous here in the US and may go by another name in the UK, but I'm sure they exist) I would suggest you contact that organization for help in this matter.
Please post to us again if there are still questions and concerns.
We all wish the very best for your friend

If he was taken to a hospital the same day this happened, they would assess his risk and start him on PEP for HIV if they decided he was, in fact, at risk.
I am not a doctor and do not know what they would (or could) do for the possible Hep C exposure. I am sure if there IS something they could do, they would.
I'm sorry this happened to your friend and we all wish him the best, but going to the hospital was the very best thing you could have done.
