Answers on Week 2 Questions

The woman had sexual intercourse with a guy without a condom. The next day she found out that he had HIV. What should she do?

This young lady should find the nearest HIV Care medical clinic. It is easy to locate HIV Care setting near you in the Life4me+ mobile app. While visiting a doctor, it is necessary to inform that a risky behavior has occurred recently and the doctor about nPEP, post-exposure HIV prophylaxis. When prescribed, this young lady should take pills without interruption for 28 days. If everything was done on time and correctly, the risks of becoming HIV-positive will be greatly reduced. It is worth noting that starting nPEP should be in the first 72 hours after a risky contact.

Does PrEP safe for the body?

PrEP means a daily intake of pills, which have some degree of toxicity.

But PrEP is delivered mainly to a young audience, where the risk of such effects is reduced. There are few studies of new drugs. Researchers want to decrease PrEP toxicity. Individual methods of prevention for different categories of people will soon be offered. For example, vaginal rings with PrEP create a barrier only in the vagina, the female's internal organs are not exposed to toxic effects of drugs. For detailed advice, contact your doctor or PrEP counselor.
