How Does Zaxine Work?

Zaxine works by inhibiting bacterial RNA synthesis, which effectively reduces the population of harmful bacteria in the gut. Taking this action can help reduce symptoms of conditions like diarrhea-predominant irritable bowel syndrome (IBS-D) and traveler’s diarrhea. Additionally, by reducing ammonia-producing bacteria, Zaxine aids in managing hepatic encephalopathy, improving cognitive function and quality of life for patients with liver disease.

Frequently Asked Questions 

How long does it take for Zaxine to take effect?

The time it takes for Zaxine to work varies based on the condition being treated. Clinical studies indicate that symptoms of travelers’ diarrhea typically improve within one to two days (about 32 hours) after starting the medication. For hepatic encephalopathy (HE) and irritable bowel syndrome with diarrhea (IBS-D), symptom improvement is usually observed within a month of beginning treatment. 

How long does Zaxine stay in your system?

After a single dose of Zaxine, it generally takes a little over a day (approximately 30 hours) to be mostly eliminated from the body. This duration is based on the medication’s half-life, which measures the time it takes for the body to reduce the drug’s concentration by half. Since the liver is involved in metabolizing and excreting Xifaxan, individuals with liver problems may experience a longer duration for the drug to leave their system.

Can Zaxine be crushed?

The manufacturer does not specify whether Zaxine can be crushed. To ensure effectiveness, it is best not to crush the tablets. If you have difficulty swallowing them whole, inform your prescriber or pharmacist. They may recommend a compounding pharmacy to create a liquid suspension of the medication for easier consumption.

How long do side effects from Zaxine last?

Side effects from Zaxine, such as headache or nausea, typically last until the medication clears from your body, which is about a day after your last dose. The length of time may differ based on the particular side effect. If you experience severe or ongoing symptoms, consult a healthcare professional for an assessment.
