HIV prevention medication is highly effective, but it can complicate blood donor screening
Taking medicine to prevent HIV might seem a good reason to feel confident about being able or eligible to give blood.
AI Summary
People who take pre‑exposure prophylaxis (PrEP) to prevent HIV are not allowed to donate blood while on the medication. They must wait three months after their last dose before they can give blood. PrEP is used by people who do not have HIV to lower their risk of infection. The NHS reports that daily PrEP is about 99 % effective when taken correctly.
