How Does Trizivir React With Other Drugs?
Trizivir can interact with other drugs or supplements you are taking. These interactions can change the amount of each drug in your bloodstream and cause an under- or overdose. New interactions are constantly being identified. Make sure that your health care provider knows about ALL drugs and supplements you are taking. Trizivir should not be taken with stavudine (d4T, Zerit®) or with emtricitabine (Emtriva®, FTC). Blood levels of lamivudine may be increased by bactrim or septra. See Fact Sheet 535 for more information on these drugs. Zidovudine’s side effects may be worse if you are taking several other drugs. Methadone may increase blood levels of zidovudine. If you take Trizivir and methadone, watch for zidovudine side effects.
