Methadone reduces risk of HIV infection in people who inject drugs, a new study says.
Researchers analyzed previous research on opioid substitution therapy (OST) and HIV transmission available from countries like the USA, Canada, UK, Netherland, Austria, Italy, Thailand, Puerto Rico, etc. A total of nine studies were selected for the analysis. The studies were mostly conducted on men between the ages of 26 and 39 years.
Researchers found that OST reduced the risk of HIV infection by 54 percent. Absolute reduction in HIV risk was difficult to calculate because the study participants had different risk backgrounds. However, researchers found an association between OST use and lower HIV risk.
