Zaxine (rifaximin) is a prescription medication used to treat hepatic encephalopathy and IBS with diarrhea (IBS-D). This oral antibiotic works in the intestines by stopping harmful bacteria from growing and producing toxins. Take Zaxine exactly as prescribed by your doctor, with or without food. The full course should be completed even if symptoms improve. Zaxine should be used cautiously in people with severe liver disease and is not recommended for certain age groups.

Zaxine 550 mg tablets are used to treat:
Zaxine (rifaximin) works in the gut by stopping certain bacteria from growing and making toxins. Since it is not absorbed much into the bloodstream, it stays in the intestines where it is needed. By blocking the bacteria’s ability to make RNA, it reduces harmful activity. For people with IBS-D, it helps calm gut bacteria, ease diarrhea, and reduce bloating. For those with hepatic encephalopathy, it reduces the amount of ammonia produced by gut bacteria. This helps prevent confusion and other serious problems.
If you want to use Zaxine for hepatic encephalopathy and IBS-D, follow these administration guidelines:
If you miss a dose of Zaxine, take it as soon as you can. If it is almost time for your next scheduled dose of Zaxine, skip the missed one. After that, continue with your regular Zaxine dosing schedule. Do not take two tablets at once to make up for a missed dose. Doing so may increase the risk of serious side effects of Zaxine.
If you take too much Zaxine, you may experience more side effects than usual. This includes nausea, stomach pain, or dizziness. However, serious problems from an overdose are rare because the drug is not absorbed much into the bloodstream. If you suspect a Zaxine overdose, contact the poison control center or your healthcare provider immediately.
