"My experience with people who are HIV positive is that those individuals usually have more worry and guilt about protecting their partners," Killian said. "One of the main reasons I started prescribing Truvada was to reduce that kind of anxiety."
Tibbett and Literski said the FDA's approval of Truvada was a "huge relief," not only for them but for other serodiscordant couples -- one person with HIV and one without -- who will now have an easier time obtaining the drug.
They said they the belief that Truvada could actually increase HIV transmission by lowering inhibitions is false.
"The people who are going to throw caution to the wind are the same people who would take risks regardless," Literski said.
By consulting with a doctor and strictly sticking to taking the pill every day, the couple said they believe their relationship is safer and stronger.
"It gives me a peace of mind to know that I'm not going to harm my partner. That's a pretty big bonus in anyone's relationship," Tibbett said.
