Description
Additional information

What is Rifaximin 550mg?

Rifaximin 550mg is used to treat certain intestinal infections caused by bacteria. It works by stopping the growth of bacteria that causes infection. Unlike many antibiotics that travel through the body, Rifaximin mostly stays in your gut, enabling it to act directly where the infection is occurring.

Rifaximin is commonly prescribed for traveller’s diarrhea, irritable bowel syndrome with diarrhea (IBS-D), and hepatic encephalopathy. It helps decrease noxious bacteria that may cause loose stools, gas, or confusion in people with liver problems.

How does Rifaximin 550mg work?

Rifaximin acts by inhibiting a critical bacterial enzyme, RNA polymerase. If this enzyme is inhibited, then the bacteria cannot produce the proteins necessary to proliferate or exist. Hence, it leads to the death of the bacteria and consequently an improvement in symptoms.

Because Rifaximin stays mainly in the intestines, it causes fewer side effects and has less of a chance of creating resistant bacteria compared to other antibiotics that circulate in the blood.

Uses of Rifaximin 550mg

Rifaximin is used to combat several health problems related to the digestive system:

Traveller’s Diarrhoea:

Rifaximin is used to treat diarrhoea caused by some kinds of E. coli. It stops the frequent bowel movements and stomach cramps so one can get well sooner.

Irritable Bowel Syndrome with Diarrhea (IBS-D):

It is common for individuals with IBS-D to have too many bacteria in the intestines. Rifaximin normalizes gut bacteria and alleviates symptoms such as bloating, discomfort, and frequent stools.

Hepatic Encephalopathy:

In individuals with liver disease, toxins produced by intestinal bacteria may affect the brain functions. Rifaximin lowers the count of these bacteria, helping prevent confusion, forgetfulness, or drowsiness.

Dosage Instructions

Take Rifaximin 550mg as directed by your doctor. Your dose and length of treatment depend upon your condition and also upon your body’s response.

Traveller’s Diarrhoea: 200mg three times a day for 3 days.

IBS-D: 550mg three times a day for 14 days.

Hepatic Encephalopathy: 550mg twice a day as directed.

Swallow the tablet with water. You can take it with or without food. Do not skip doses, and complete the entire course even if you begin to feel better.

If you forget to take a dose, take it when you remember. If it’s nearly time for your next dose, then skip the missed dose. Do not take two doses together.

Possible Side Effects

Most people tolerate Rifaximin 550mg well. Common side effects are usually mild and short in duration. You may notice:

If you develop severe diarrhoea, a rash or swelling, contact your doctor immediately. Rarely, a few people may have an allergic reaction or new infection of resistant bacteria.

Drug Interactions

Rifaximin acts mainly in the gut; interactions are minimal. However, always notify your physician about the use of other medications or supplements.

Do not take it with certain antibiotics or drugs that affect its absorption. Your doctor may want to monitor you closely if you are being treated for liver or kidney problems.

Before taking Rifaximin, tell your doctor if you have:
