More than 5000 questions have answers already online –  organised into over 30 categories. Your answer may already be here.

Please check the date of the answers! Guidelines change and older answers may only be accurate for time they were posted. Some older questions have been updated, and this is clarified at the end of the post.

Important information about this service

We are very sorry that we do not answer questions about HIV TESTING or about HIV TRANSMISSION – see: Why doesn’t i-Base answer questions on HIV testing and transmission?

We also have a new online factsheet about PEP. If your question is about PEP, please look here first .

Questions are answered by a team of treatment advocates at i-Base. We are not doctors or nurses – see: Who answers these questions?

Information is to be used in discussion with your doctor.

We use everyday language to answer your question personally. The more information you include, the better we can do this. For example, it helps to include your current CD4 count, whether you are on treatment and how long you have been HIV positive etc.

Please tell us which country you live in. This is because guidelines and treatment are different in different parts of the world.

Information we provide is based on latest treatment guidelines and research. Answers are based on best available evidence and references are included when appropriate.

If you are in the UK and worried about HIV transmission and testing or would like advice on counselling, benefits, housing or legal questions

Please contact THT Direct (0808 802 1221) or visit THT’s website.
