What Is A Generic?×
A generic drug is essentially a copycat version of a brand-name medication, offering the same safety, quality, and effectiveness, but often at a lower cost. When a brand-name drug's patent expires, other companies can produce the generic version. These generics contain the same active ingredients and work in the same way in the body as the original brand-name drug. However, they might differ in color, shape, or inactive ingredients. The appeal of generic drugs lies in their affordability; they provide a more cost-effective option for consumers without sacrificing the benefits of the original medication. This makes healthcare more accessible to a larger portion of the population, ensuring that more people can receive the treatment they need without the burden of high costs associated with brand-name drugs.
The antibacterial agent Rifaximin plays a vital role in medical treatment as part of the rifamycin antibacterial family. Combined with lactulose, it contributes to preventing hepatic encephalopathy recurrence in adults. People with chronic liver disease are frequently affected by hepatic encephalopathy, which impairs the ability of the body to eliminate waste products such as ammonia efficiently. Uncontrolled accumulation of ammonia can result in neurological changes, coma, or even death. By eliminating ammonia-producing bacteria in the digestive system, Rifaximin effectively addresses this issue. The medication primarily affects the gastrointestinal tract due to its limited absorption into the bloodstream.
Additionally, Rifaximin relieves irritable bowel syndrome (IBS) with diarrhea. As a result, symptoms such as bloating, stomach pain, and diarrhea are improved due to reduced bacterial populations and related products in the gut.
Rifaximin may be marketed under different brand names and forms; not all brands are appropriate for all conditions. Physicians may prescribe this medication for other services as well. Consult your healthcare provider before discontinuing Rifaximin if you have yet to discuss its purpose with your doctor.
Even if they exhibit similar symptoms, it is crucial not to share this medication with anyone else. Consumption of Rifaximin without a prescription can be harmful and should be avoided.

Different Forms and Administration Guidelines
Rifaximin is available as pink, oval-shaped, biconvex tablets imprinted with “rfx” on one side. Each tablet contains 550 mg of rifaximin, accompanied by nonmedicinal ingredients such as colloidal silicon dioxide, glyceryl distearate, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, red iron oxide, sodium starch glycolate, talc, and titanium dioxide.
For the prevention of hepatic encephalopathy recurrence, the recommended adult dosage of Rifaximin is 550 mg, taken twice a day. In the case of irritable bowel syndrome with diarrhea, the prescribed adult dosage entails taking one tablet three times a day.
To ensure optimal efficacy, Rifaximin should be ingested on an empty stomach. Swallow the tablets whole with water, avoiding crushing or chewing them. Dosage adjustments may be necessary based on individual factors such as body weight, concurrent medical conditions, and other medications. Any modifications to the prescribed dosage should be made in consultation with your healthcare provider.
Strict adherence to the prescribed regimen is vital for maximizing the benefits of Rifaximin. In case of a missed dose, take it as soon as possible and continue with the regular schedule. However, if the next dose is approaching, skip the missed one to avoid a double dose. If you are uncertain about the appropriate action to take after missing a dose, seek advice from your doctor or pharmacist.
Store Rifaximin at room temperature, protect it from light and moisture, and ensure it remains inaccessible to children. Proper disposal of unused or expired medication is crucial, so consult your pharmacist regarding the appropriate method.
Who Should Refrain from Taking Rifaximin?
Avoid using Rifaximin if you have a known allergy to rifaximin or any ingredients present in the medication. Additionally, individuals allergic to other rifamycin antibacterial drugs should also refrain from using this medication.
Potential Side Effects and Precautions
As with any medication, Rifaximin may produce side effects, which can vary in severity, duration, and occurrence. It is important to note that not everyone experiences these side effects, and their presence should be evaluated in relation to the medication’s benefits.
Some commonly reported side effects, experienced by at least 1% of individuals, include bloating, mild diarrhea, dizziness, headache, itchiness, nausea, and reddish discoloration of sweat, urine, or tears. Most of these side effects are manageable and tend to diminish over time. Consult your doctor or pharmacist if any of these side effects become severe or bothersome.
Although infrequent, certain side effects can potentially lead to serious complications if left unaddressed. Contact your doctor immediately if you experience abdominal pain, muscle spasms, signs of depression, or a skin rash. Furthermore, seek immediate medical attention if you notice signs of bowel inflammation or severe allergic reactions.
Before initiating Rifaximin treatment, it is crucial to inform your doctor about any pre-existing medical conditions, allergies, current medications, and pregnancy or breastfeeding status. Antibiotic-related diarrhea, known as pseudomembranous colitis, can occur with Rifaximin usage. If severe diarrhea occurs during or shortly after treatment, promptly notify your doctor.
Individuals with liver disease or impaired liver function should exercise caution while using Rifaximin, as it may accumulate in the body, potentially leading to side effects. Regular liver function tests may be necessary, and your doctor can provide guidance on monitoring liver health during treatment.
The use of Rifaximin during pregnancy should be carefully considered, with the potential benefits outweighing the risks. In the event of pregnancy while using this medication, contact your doctor immediately for appropriate guidance. Breastfeeding mothers should consult their healthcare provider to assess the potential effects of Rifaximin on their infants.
Regarding the safety and effectiveness of Rifaximin in children, no established data are available. Therefore, its use in pediatric patients has not been determined.
Potential Drug Interactions
Rifaximin may interact with various medications, leading to altered effectiveness or increased risks. Some notable interactions include amiodarone, “azole” antifungal medications, BCG vaccine, carvedilol, cyclosporine, dronedarone, elagolix, eliglustat, erdafitinib, flibanserin, hepatitis C antivirals, lapatinib, lumacaftor and ivacaftor, macrolide antibiotics, osimertinib, propafenone, quinidine, quinine, ritonavir, sodium picosulfate, verapamil, and warfarin. It is crucial to inform your doctor or pharmacist about all medications you are currently taking, including prescription, over-the-counter, and herbal products. Based on your specific circumstances, your doctor may recommend adjusting the dosage, substituting medications, or maintaining the current regimen without modifications.
Remember that interactions between medications do not always necessitate discontinuation. Your doctor can guide you on managing and addressing potential drug interactions.
Inform your doctor or prescriber about any medications, including caffeine, alcohol, nicotine, or recreational drugs, as they can influence the action and efficacy of various medications.
In conclusion, Rifaximin serves as a valuable medication for hepatic encephalopathy recurrence prevention and the treatment of irritable bowel syndrome with diarrhea. By understanding its mechanism, administration guidelines, potential side effects, precautions, and drug interactions, you can utilize Rifaximin effectively under the guidance of your healthcare provider.
