Parlox Sparfloxacin Warfarin Sodium
MinorThe leaflet for Sparfloxacin (sold as Spark) says it does not interact with warfarin. So if you are taking warfarin and your doctor adds Sparfloxacin, the leaflet does not expect Sparfloxacin to change how warfarin works in your body. The same leaflet also lists theophylline, caffeine and cimetidine as medicines it does not interact with.
Little or no effect is expected. You usually do not need to change anything, but still tell your doctor or pharmacist about every medicine you take.
