Commentary on the possibility that Viagra may contribute to transmission of HIV and other sexual diseases among older adults

Psychol Rep. 1999 Dec;85(3 Pt 1):942-4. doi: 10.2466/pr0.1999.85.3.942.


Many older male adults experiencing impotence are being treated with Viagra. Scientific and media reports indicate that this medication is effective in re-establishing sexual relationships among these men. Despite the benefits that Viagra may have in the treatment of impotence among older adults, increased sexual activities could also facilitate the spread of HIV infection and other sexually transmitted diseases. This holds for older adults who may lack factual knowledge of HIV transmission and perceive themselves as nonsusceptible to this disease. Prescription of Viagra in combination with HIV/AIDS prevention programs may be helpful.
