Key takeaways
Talicia (omeprazole/amoxicillin/rifabutin) and clarithromycin are both used to treat infections, but they have some key differences. Talicia is a combination of three medications: a proton pump inhibitor (omeprazole), a penicillin antibiotic (amoxicillin), and a rifamycin antibiotic (rifabutin). It is specifically used to treat *Helicobacter pylori* (H. pylori) stomach infections in adults and is only available as a brand name medication. Clarithromycin, on the other hand, is a macrolide antibiotic available in generic form and treats a variety of bacterial infections, including lung, sinus, and skin infections, as well as *H. pylori* stomach ulcers. Talicia is taken as four capsules every 8 hours for 14 days, while clarithromycin dosing varies based on the infection type and can be taken as immediate-release or extended-release tablets. Talicia is not recommended for those with liver or severe kidney problems, while clarithromycin has many drug interactions and is not the best option for those with kidney issues. Both medications can cause serious side effects, but Talicia can also change the color of your skin and body fluids, which is not a side effect of clarithromycin.
