Key takeaways
Trizivir (abacavir/lamivudine/zidovudine) and Baraclude (entecavir) are both antiviral medications, but they are used to treat different conditions. Trizivir is a combination medication used for HIV treatment, while Baraclude is primarily used for hepatitis B. Both medications belong to the nucleoside reverse transcriptase inhibitor (NRTI) class, but Trizivir combines three NRTIs, whereas Baraclude contains only one. Trizivir is taken as one tablet twice daily, while Baraclude is typically taken once daily on an empty stomach. Trizivir is available in generic form, making it more affordable, whereas only the tablet form of Baraclude has a generic version. Common side effects of Trizivir include nausea, headache, and fatigue, while Baraclude may cause headache, fatigue, and dizziness. Trizivir requires a genetic test before starting due to the risk of a severe allergic reaction, and it is not recommended for people with heart problems. Baraclude, on the other hand, is not recommended for those with both hepatitis B and untreated HIV due to potential drug resistance.
