Some clinics will support you and provide advice and testing if you buy PrEP online. However, the NHS is only responsible for meds that it supplies.
First, please talk to a health adviser, nurse, doctor or community worker. These people can help you if you want to start PrEP, or are already taking it.
Then it is essential to have an HIV test before or as you start.
If you are already HIV positive and don't realise it, you could develop drug resistance.
Ask for a 4th generation HIV blood test. This is also called an antigen/antibody test. This will tell you if you have HIV so long as you haven't had other risks in the last six weeks.
Most finger prick tests are currently 3rd generation. This test needs 2-3 months to show a positive result. Don’t rely on a finger prick test before PrEP if you have a more recent risk.
If you are just starting PrEP and had a risk in the last six weeks, have another 4th generation HIV test six weeks after starting. This is to be sure an early infection is not missed.
