Pre-Exposure Prophylaxis (PrEP)
|Is Truvada® as PrEP Safe?
Truvada® can cause minor side effects in some people, but, typically, these subside during the first month of taking Truvada® as PrEP. Common side effects include: upset stomach, headache, vomiting, and loss of appetite. Some people will experience more serious side effects including loss of bone density (1 in 100), or kidney issues (1 in 200). If you are taking Truvada®, tell your provider about any side effects that are severe, or do not go away within a month.
|If I Take Truvada® as PrEP, Can I Stop Using Condoms?
You should not stop using condoms if you are taking Truvada® as PrEP. Truvada® helps protect you against HIV. It does not offer protection against other STDs or pregnancy. While taking Truvada® as PrEP daily can significantly reduce your risk of HIV infection, using condoms in conjunction with PrEP will reduce your risk even further.
|How Effective is Truvada® as PrEP?
Studies have shown that Truvada® as PrEP reduces the risk of HIV infection from sex by more than 90% and from injection drug use by 70% when used consistently.
Adherence is Key! You must be willing and able to follow a regimen of oral Truvada® taken once daily. In addition, you will need to schedule provider visits every 3 - 4 months for lab work, and HIV testing.
|If you decide that Truvada® as PrEP is right for you?
Talk to your health care provider and get informed on all the facts. Working together with your provider is the best defense against HIV.
