 [ Symptoms ] how is a female sexual problem diagnosed [ Disease ] to your last point about sharing razors and piercings with your friend you should not do this not because your friend might be infected with hiv but because it is not hygienic under any circumstances there are many other bloodborne illnesses you could get from sharing razors needles and other items including hepatitis c to your larger question there probably is no way for you to know for sure what is going on with your friend due to patient privacy laws you cannot for example call up her doctor and ask if she has hiv or not it is highly unlikely that she would be prescribed complera if she did not have hiv 1 most medications can be prescribed off label  that is doctors can use prescription medications for conditions other than the ones they were approved to treat however it is unlikely that a medication like complera would have many off label uses i feel you have to err on the side of caution here go and get an hiv test on yourself it is a good idea to do this regularly anyway if you are sexually active or if you share needles razors or other items that can transmit viruses wishing you well
