Unprotected intercourse with HIV positive. Is there any medication that can prevent the infection?

Doctor, maybe about an hour ago I had unprotected intercourse with someone who may be HIV positive. Is there a way that I can be tested now or are there any medications that can prevent the infection? I know it was quite unresponsable of myself to have had unprotected sex and I normally always use a condom. Thank you for your help in advance

Although there are very less chances for a person to get HIV with just one unprotected sexual encounter but still you should not take any chance.
The best is to go for post-exposure prophylaxis (PEP).
 This is a one-month course of anti-HIV drugs that, if started within 72 hours of potential exposure, may reduce the risk of HIV infection. If PEP does not successfully prevent HIV infection in someone, the presence of the PEP drugs may still reduce HIV replication until the drugs are finished. This may delay the time it takes for a person’s body to create HIV antibodies.
After a one month course you can go for HIV detection tests.
Please consult your doctor as early as possible and start PEP.
