Can nurse counseling and daily texts keep HIV prevention pills on track?
NCT ID NCT04316715
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers at the University of Miami are testing two ways to help men who have sex with men take their HIV prevention medication, known as PrEP, more consistently. One group receives four weekly counseling sessions with a nurse, using techniques from cognitive behavioral therapy and motivational interviewing, plus optional booster sessions. Another group gets daily text message reminders to take their pill. The study measures medication levels in dried blood spots and self-reported adherence over 18 months to see which approach works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A behavioral program of four weekly nurse-led counseling sessions plus daily text message reminders
- What this could lead to
- If the counseling and text reminders help, this approach could become a practical way to support people in taking HIV prevention medication consistently.
- What could go wrong
- Behavioral support does not work for everyone, and text reminders can be easy to ignore. The study measures pill levels in blood over 18 months, so real-world adherence may still fall short of the target.
